Greenhouse growers are always looking for ways to increase crop yields, improve plant quality and maximize efficiency. One of the most effective strategies to achieve this is through CO2 enrichment in greenhouses. By enhancing the concentration of carbon dioxide inside the space, growers can stimulate plant growth, shorten production cycles and ultimately improve profitability.

Below, we explore the role of carbon dioxide supplementation in greenhouses and how to manage and control conditions for optimal results.

Understanding CO2 Enrichment in Greenhouses

CO2 enrichment is the practice of adding extra carbon dioxide to the air inside a greenhouse to help plants grow faster and healthier. In nature, plants rely on sunlight, water and CO2 to perform photosynthesis. However, in closed spaces, plants can quickly use up the available CO2, which can slow their growth. This is where greenhouse CO2 enrichment comes in. 

By increasing CO2 levels, growers can boost photosynthesis, improve plant development and increase yields. This technique is commonly used in commercial applications to get stronger, larger plants and more productive harvests. 

The Science Behind CO2 and Plant Growth 

The effect of supplemental CO2 on plant growth is well-documented in both research and commercial practice. Photosynthesis increases dramatically when CO2 levels are raised to around 800–1,000 parts per million (ppm). 

The advantages of CO2 enrichment in greenhouses are not just theoretical. They translate into real, measurable gains for growers:

  • Thicker stems, larger leaves and more developed fruits and flowers
  • Enhanced root and shoot growth
  • Faster leaf development
  • Shorter production cycles

The effects of CO2 levels on plants may vary between species, but most greenhouse crops respond positively to carbon dioxide supplementation.

Different Methods of Carbon Dioxide Supplementation

There are several ways to apply greenhouse carbon dioxide supplementation, each with its own advantages. 

1. CO2 Generators

These generators work by burning fuels like natural gas or propane, which release carbon dioxide as a by-product. When the generator runs, it pulls in oxygen from the surrounding air, mixes it with the fuel and combusts it in a controlled chamber. This combustion process creates CO2 gas along with a small amount of heat and water vapor.

2. Compressed CO2 Tank

Many growers use supplemental CO2 from compressed CO2 tanks. These tanks are filled with CO2 gas that has been compressed under high pressure. They provide pure carbon dioxide without adding heat or moisture, making them perfect for greenhouses in warmer climates or during summer.

3. Dry Ice

Dry ice use in greenhouses is a simple and efficient option for small-scale growers or specific zones within a controlled space. In a greenhouse, when you place dry ice (solid CO2) out in the open, it gradually turns into CO2 gas and raises the carbon dioxide levels in the air. This makes it a simple and effective method of CO2 enrichment.

How to Control Greenhouse Conditions for Best Results

Effective control of greenhouse conditions is essential to get the most from CO2 enrichment. Here are a few important management practices:

  • Monitor CO2 levels: You can monitor these levels with reliable sensors to maintain the target range.
  • Ensure ventilation systems: Ventilation needs to be adjusted to prevent CO2 loss, especially during warm weather when vents open for cooling.
  • Maintain proper humidity and temperature: Excessive moisture can reduce CO2 uptake, and high temperatures can stress plants.
  • Coordinate lighting and CO2 timing: CO2 supplementation is only useful when plants are actively photosynthesizing, so it should be applied during daylight hours or when artificial lighting is used.

For the best outcome, you can work with a knowledgeable gas supplier to design a customized CO2 delivery system suited to your operation’s size and crop mix. 

Frequently Asked Questions 

Before implementing carbon dioxide in your space, it’s essential to understand it thoroughly. Looking at some frequently asked questions can help you make informed decisions. 

What Is CO2 Enrichment in Greenhouses and Why Is It Important?

CO2 enrichment increases carbon dioxide levels above the natural atmosphere inside the house. This is important because plants need carbon dioxide. It is a key ingredient in photosynthesis, the process by which plants make food. When CO2 levels are supplemented, most crops grow faster, develop stronger stems and leaves, and produce higher yields.

How Much CO2 Should I Add to My Greenhouse?

Most greenhouse crops respond well to CO2 concentrations between 800–1,000 ppm. However, the effects of CO2 levels on plants can vary depending on the species. It’s always best to monitor CO2 levels using sensors and work with a gas supplier to customize the right concentration for your crops.

What Is the Effect of Supplemental CO2 on Plant Growth?

The effects include faster leaf development, stronger root systems, increased flowering, larger fruits and shorter production cycles. This leads to healthier plants and higher overall yields.

Are There Safety Concerns With Carbon Dioxide for Plants?

Yes. While CO2 is safe for plants at recommended levels, it can pose risks to people if it accumulates in enclosed spaces. Always follow safety guidelines, including proper ventilation and CO2 monitoring. If you’re using dry ice or gas cylinders, handle them carefully and consult credible resources for best practices.

What Are the Most Effective Methods of CO2 Enrichment?

There are several options, depending on the size of the operation and the grower’s needs. CO2 generators are great for large greenhouses. Compressed CO2 tanks are ideal for both small and large spaces, while dry ice is a good option for small spaces or short-term use. Whichever option you choose, maintaining the right CO2 levels with the help of sensors and timers is key to getting the best results.

Raising carbon dioxide (CO2) levels in a cannabis grow room can help plants develop faster, grow healthy foliage and produce resinous, bountiful buds. Knowing how to increase CO2 and what amount would benefit your grow area for maximum harvest is essential.

Growers can implement many techniques to boost growth and terpene production. CO2 enrichment is an industry secret that helps companies produce large amounts of healthy buds and keeps plants strong throughout the stages.

Read on for more information on what CO2 enrichment is, how to use it and how to overcome some of the associated challenges.

Why Is CO2 Important for Cannabis Plants?

CO2 is a key component of photosynthesis. It allows cannabis plants to convert light into energy, which keeps the branches and buds strong and enables the plant to produce higher amounts of resin. Enriching the grow process with CO2 is one of the top cannabis cultivation techniques, allowing growers to create larger yields with potent, glistening trichomes and fewer duds.

Studies show that elevated CO2 concentrations can boost plant growth. Raising CO2 levels in the right stage of cannabis growth can spur foliage development, offer plants more protection and allow strains to reach their full potential.

What Are the Benefits of CO2 for Cannabis Cultivation?

Increasing CO2 concentrations in the grow area is the secret to maximizing yield in cannabis cultivation. When paired with strategies like sea of green and low-stress training (LST), CO2 enrichment can keep plants nourished and ensure each bud is coated in sufficient resin. Sturdy branches, stems and foliage are especially beneficial when the plants undergo LST or other forms of stress training to amp up bud and trichome production.

These benefits highlight the role of carbon dioxide in plant growth:

  • Increased yield: CO2 enrichment can help plants develop bigger flowers and provide larger yields. Cultivators growing lower-yield strains can get the most out of the growth by enhancing CO2.
  • Optimized environmental control: CO2 enrichment can contribute to the health of the overall environment. It helps cultivators increase CO2 levels in the air around the cannabis plants, which boosts photosynthesis and plant growth.
  • Improved attributes: An increased availability of CO2 encourages plants to allocate their resources toward metabolites like terpenes and cannabinoids. These metabolites affect the aromas, therapeutic properties and flavors of cannabis.
  • Increased speed: CO2 enrichment can increase growth rapidly and help cultivators deliver popular strains quicker, ensuring suppliers or dispensaries can provide the high-demand cultivars.
  • Improved endurance: CO2 enrichment can help cannabis plants survive under harsh greenhouse conditions and droughts, which may be beneficial when growing complex strains and working in challenging environments.

Contact a Meritus Gas team expert for more information on how you can use CO2 to reap more benefits in your cannabis cultivation area.

How to Use CO2 to Maximize Cannabis Yield and Quality

Understanding the role of CO2 generators in cannabis plant development can inspire cultivators to enhance their growth with CO2. Knowing how and when to increase CO2 levels is crucial.

Cannabis plants go through three main growth stages — seedling, vegetative and flowering. During each phase, the plants have different needs for nutrition and CO2. The best stage to implement CO2 enrichment is the vegetative stage, when plants are actively growing new branches and foliage. Increased CO2 levels in this stage can help plants develop stronger branches and sturdier colas.

CO2 enrichment can also be helpful at the beginning of the flowering stage when buds are starting to form. Nourished, healthy plants produce bigger, juicier buds that reach their full potency levels.

Increasing CO2 levels during the vegetative and beginning of the flowering stage is beneficial for both male and female plants. Cultivators creating new strains can also benefit from CO2 enrichment when breeding new strains.

Steps to Use CO2 to Enrich Cannabis Plants

Cultivators can use CO2 to stimulate plant growth and deliver quicker, more prominent harvests. These steps are typically involved in enriching plants with CO2:

  1. Find the suitable CO2 levels: Generally, an increase of ambient CO2 of around 800-1,000 ppm is the key to significantly boosting yield, but the amount may vary depending on the cannabis strain, grow room size and desired results.
  2. Maximize light intensity: CO2 enrichment produces the best results when paired with higher light levels, which promotes more efficient photosynthesis. Most cannabis strains thrive under high light conditions anyway, so maximizing the light intensity won’t require too many extra steps.
  3. Monitoring CO2 levels and other environmental factors: When utilizing CO2 enrichment, cultivators must monitor CO2 levels regularly to ensure plants don’t become stressed. They can adjust CO2 levels accordingly to enhance growth.

Speak to a Meritus Gas team expert about the steps you can take to incorporate CO2 enrichment in your unique cannabis cultivation business.

Challenges in Cannabis Growing

Enriching cannabis plants with CO2 can substantially improve growth, but growers must prioritize the role of sensors in cultivation. Elevated CO2 levels can cause an increase in temperature and humidity. It’s important to monitor relative humidity (RH) and temperature to ensure the particular cannabis strain has the required environmental conditions.

Provide adequate airflow when raising CO2 levels. Monitoring RH levels is particularly essential when working with plants that are prone to mold and mildew. Sufficient airflow also aids in even CO2 distribution within the grow area.

Another potential challenge is safety issues with high CO2 concentrations, which can be harmful to human health. It’s crucial to follow safety measures in grow rooms. One example is the OSHA CO2 exposure limit of 5,000 ppm for an eight-hour shift.

Carbonation is crucial to the beverage industry as it allows you to offer a range of drinks to suit diverse client tastes. Through carbonation, you can produce sodas, sparking water, fizzy fruit juices and even alcoholic beverages. By carbonating beverages, you can boost a drink’s taste, aroma and mouthfeel.

Successfully carbonating soda involves understanding how carbonation techniques work and having the right equipment for commercial soda carbonation. This guide to soda carbonation explores the chemical process of carbonation, including the role of carbon dioxide (CO2), essential equipment and how to maintain beverage systems.

Making Soda Through Forced Carbonation

There are two main carbonation methods in the beverage industry — bottle carbonation, also called bottle conditioning, and forced carbonation.

Bottle carbonation is used for alcoholic beverages. You add sugar to a fermented drink and allow the yeast to convert the sugar into CO2. This process is time-consuming and labor-intensive and is not suited for carbonating soda. 

Forced carbonation is the most effective way of carbonating drinks to make soda. In this method, you use a bulk CO2 storage system and a carbonator tank, which is a pressurized vessel, to pump pressurized CO2 gas into your liquid. For soda, the liquid is a concentrated flavoring or beverage base combined with water and a sweetener to form a syrup. A carbonator pumps the CO2 gas to dissolve it into the liquid in the pressurized tank. The pressurized, dissolved CO2 gives soda its characteristic bubbles and fizz. 

Depending on your commercial setup, you will either store your drinks in a pressurized system with a dispenser — like you would see in fast food chains with soda fountains — or bottle your beverage under pressure to ensure it does not go flat.

CO2 Sources and Gas Purity Standards

To make carbonated drinks commercially, you need to use beverage-grade CO2. The Food and Drug Administration sets the criteria and standards for beverage-grade CO2 to ensure it is suitable for consumption. Generally, the gas should be purified to be suitable for its intended use, free of contaminants, and tested and analyzed to avoid an unpleasant taste or odor.

Sourcing your CO2 from a reputable provider helps ensure that the gas is suitable for your sodas.

CO2 Safety Practices

Implementing the appropriate safety measures in any industry that works with CO2 gas and pressurized gases is essential. CO2 is an asphyxiant because it displaces oxygen. Doing the following is crucial to working more safely with CO2 and pressurized gas:

  • Work in a space with proper ventilation.
  • Install CO2 alarms to monitor levels.
  • Regularly inspect and maintain all CO2 delivery systems.
  • Never modify or tamper with CO2 equipment or systems.

Carbonation Levels in Different Drinks

Different beverages have differing carbonation levels, which affect their overall characteristics and properties. For example, sodas generally have higher carbonation levels than sparkling water. Beers, sparkling wines, champagnes and cocktails also have different carbonation levels.

You can use a pressure gauge or carbonation meter to measure the carbonation in your beverages. Soda generally has between 3 to 4 volumes or the equivalent of 6 to 8 gallons per liter of CO2. It is important to remember that you can vary these levels depending on the type of drink you are producing and how that will match your customers’ preferences.

Equipment and Maintenance for Carbonation

The right equipment is essential for forced carbonation techniques to produce commercial sodas. The carbonator is one of the most important components in your beverage system, as this is where your beverage mix and CO2 combine to produce soda.

Choosing the right size beverage carbonation tank is essential for meeting your production demands and having a system you can maintain. Speaking to a professional about the right beverage system for you can help you determine the right size for your productions. You can also explore customizable beverage system solutions that cater to your industry, whether you’re a beverage distributor or own a commercial establishment.

Another essential piece of equipment is a backflow preventer that stops the carbonated liquid from pushing back into the potable water supply. A backflow preventer is critical if you have systems with copper water lines or pipes, as the carbonated liquid can erode the copper and contaminate the potable water.

Maintaining your beverage systems is key to your equipment’s longevity and efficiency. Thoroughly and regularly cleaning your system can help you keep it in top condition.

Troubleshooting Common Issues

Like any technique, you may encounter a few common issues when carbonating soda. Thankfully, most of these concerns are simple to troubleshoot:

  • Flat soda: If your beverages are flat, check that your carbonator is plugged in and functioning normally. If you have an issue with the carbonator, call your provider to repair or replace the unit. You can also check your CO2 tank in a ventilated space to ensure it still has sufficient gas and isn’t leaking. Call a professional gas provider immediately if the tank appears to be leaking. 
  • You are getting only syrup: If you notice you are not getting fizzy water and the system is supplying only syrup, your water source may be faulty. Additionally, there may be kinks in the hose preventing water from flowing to the unit. 
  • Soda discoloration: If your soda appears discolored or dirty, your dispensing nozzle and other parts of your unit may need cleaning and sanitizing. Contact your system supplier if you continue getting discolored soda after cleaning the unit. 

Advanced Calibration Techniques

The Brix scale is a way of measuring the sugar content in food and beverages. Advanced calibration techniques like Brix calibration can help you fine-tune the taste of your drinks. Brix calibration is a way of adjusting the water-to-syrup ratio for each of your soda flavors. 

An indication that you may need Brix calibration is if customers say the soda is too sweet or too watery. This regulation solution is an excellent method for quality control and producing consistent beverages.

Carbon dioxide (CO2) is an odorless, colorless, non-flammable gas naturally present in the atmosphere at safe levels. However, CO2 can pose a significant health risk when it accumulates in an enclosed space. This can happen when working with dry ice — the solid form of CO2 — or because a CO2 container or pipe leaks in a building with insufficient ventilation.

If you work with CO2, you must be aware of the health risks and how to handle a situation where CO2 levels become too high. This article outlines the symptoms of CO2 exposure, safety regulations, handling guidelines and leak detection tools. We also cover the importance of an emergency response plan and what to do in a CO2 emergency.

CO2 Health Risks

CO2 gas is relatively harmless on its own, but prolonged exposure to high concentrations of CO2 gas or contact with dry ice can result in serious health concerns. Understand the following CO2 health risks and overexposure symptoms to stay safe.

CO2 Gas

The main health risk associated with CO2 gas is asphyxiation. This can happen when there are high concentrations of CO2 in an enclosed space, as the gas will displace the oxygen in the air and make it hard to breathe. Symptoms start with drowsiness, headaches, an increased heart rate, nausea and dizziness. They can progress to difficulty breathing, convulsions, loss of consciousness and death as CO2 levels rise.

Most people will start to see mild CO2 exposure symptoms after a few hours of inhaling air with a CO2 level of 2,000 parts per million (ppm). More severe symptoms occur above 5,000 ppm, and a concentration of 40,000 ppm is immediately dangerous. Moving to an area with clean air will help relieve less severe symptoms.

Dry Ice

Handling dry ice and dry ice containers without the correct protection can result in frostbite. Dry ice freezes at -109 degrees Fahrenheit (-78 degrees Celsius), and frostbite occurs at temperatures below 31 degrees Fahrenheit or -0.55 degrees Celsius. With prolonged exposure, dry ice can cause numbness, burning sensations, blistering and tissue death.

Dry ice also sublimates incredibly fast at room temperature, which can cause rapid asphyxiation if there is insufficient ventilation. Dry ice kept in an enclosed container can also explode if the pressure rises too high. An exploding container can cause damage to the surrounding area and injure people nearby.

CO2 Safety Regulations

Paying close attention to and following industry standards for proper CO2 handling is key. The Occupational Safety and Health Administration (OSHA) sets exposure limits for those working with CO2. The OSHA permissible exposure limit for an eight-hour period is 5,000 ppm. The average CO2 level over that period cannot exceed 5,000 ppm. Always consult with local authorities regarding the safety regulations in your area.

How to Handle Carbon Dioxide Safely

Knowing the safety guidelines and precautions for working with CO2 helps increase safety and reduce risk within the workplace. The Compressed Gas Association (CGA) has created specific guidelines for working with dry ice and CO2 gas you can follow to protect yourself and others.

  • Training programs: All staff working with or around CO2 and dry ice must receive CO2 safety training. They should understand how to handle CO2 containers, the symptoms of CO2 exposure and how to respond to a leak or health emergency.
  • Install detectors: Install CO2 detectors in areas exposed to CO2 to warn occupants when levels rise too high. The detectors must have both audible and visual warning cues. Regularly inspect all alarms and equipment to ensure they are working as intended.
  • Monitoring levels: Always check the CO2 levels before entering a storage area. Only trained staff wearing the correct PPE should enter an area with a high CO2 concentration.
  • Ventilation: Rooms and vehicles with dry ice and CO2 gas must have sufficient ventilation to prevent CO2 buildup.
  • Personal protective equipment: Always wear the correct clothing, eye protection and additional gear when handling CO2 containers or entering a CO2 storage room. Use tongs or gloves to move pieces of dry ice and avoid direct skin contact.
  • Safe storage: Always store gas cylinders securely, upright and away from heat. Keep dry ice in a well-ventilated container that prevents pressure buildup.
  • Signage: Label all containers, rooms and areas with CO2 exposure risks clearly. Signs and labels should warn users of CO2-related risks and what to do in an emergency.

CO2 Leak Detection Equipment

Active CO2 detection techniques are the most effective way to warn of high CO2 accumulations in a confined space. One common piece of active detection equipment is a CO2 alarm. The alarm includes a CO2 sensing probe installed in the confined space and a control unit on the outside. The control unit displays the CO2 level within the space at all times. It uses both audible and visual indicators to warn of high CO2 levels.

Other leak detection tools, including over-run alarms, nitrogen separators and in-line flow meters for beverage gas monitoring, are available. If you currently use the passive leak detection technique of a ball floating inside a flow meter, we recommend you change to another method. This method is ineffective during busy service times.

Preparing for Emergency Situations Involving CO2

Businesses that use CO2 in their daily operations should prepare an emergency response plan for dangerous CO2 situations. This plan should include emergency numbers, a map of all CO2 systems in the building and escape routes and meetup points. Teach the plan to all staff working with CO2 and have it accessible in work areas. Staff should also be aware of areas where CO2 could accumulate to toxic levels.

If you suspect you currently have a CO2 leak, identify possible confined spaces that may accumulate high concentrations of CO2 or nitrogen. CO2 collects in low-lying and confined areas, so keg coolers, closets, basements and enclosed rooms are dangerous during a leak. Air out any contaminated areas thoroughly before entry. All staff must immediately evacuate the building at the first signs of a leak.

Do not enter the area if you suspect there is a chance of compressed gas accumulation. If you can, shut off the gas supply that feeds the leak without placing a person at risk of entering a confined space. Contact emergency services if you can’t safely shut off the gas supply to the leak or if you think there is a safety concern.

The beer-brewing process has been around since the civilization of Mesopotamia, and records suggest they brewed fermented beverages with honey and dates. Today, there are hundreds of different varieties of beer with a wide range of tastes and appearances. However, a few things remain consistent if you want to brew the perfect beer — one of them is the importance of carbon dioxide (CO2).

The Role of Carbon Dioxide in Brewing

Carbon dioxide is a natural by-product of the beer brewing process. During the fermentation stage, yeast breaks down the sugars from the beer wort into alcohol and CO2. The result is carbonation, which produces the bubbles and foam, or head, at the top of a poured beer.

Different beers have different amounts of carbonation. For example, American-style lagers tend to have very high carbonation levels, whereas certain barleywines or stouts have lower CO2 levels.

Carbon dioxide levels impact the beer’s:

  • Taste: Higher CO2 levels correspond to higher levels of bitterness and sour taste, while lower CO2 levels tend to create less bitterness and sour taste in beer.
  • Mouthfeel: Higher CO2 levels contribute to a thinner mouthfeel, while less CO2 creates a more full mouthfeel in beers.
  • Quality: Carbonation levels in beer also affect the taste, as the CO2 interacts with taste buds on the tongue to bring certain flavors forward.
  • Shelf stability: More CO2 in packaged beer can extend the shelf life by dissolving excess oxygen.

Carbonation Techniques in Brewing

During packaging, many breweries add additional CO2 to reach the correct carbonation levels for the type of beer. They can do this through secondary fermentation or by introducing additional gas.

Secondary Fermentation

If the end result of fermentation does not reach the peak carbonation for that type of beer, it will undergo a secondary fermentation, or refermentation process. By adding a small amount of sugar — called “priming sugar” or “primings”  — another small fermentation occurs and creates additional carbon dioxide. This method is mostly used by home brewers and smaller brewing operations through a process called bottle conditioning.

Gas Injection

Commercial beer production methods introduce CO2 gas rather than relying on secondary fermentation. This carbonation technique works because it allows for faster processing, more control and consistent results. With the right equipment and monitoring tools, you can achieve precise carbonation levels so every sip of beer — whether from a can, bottle or keg — has the exact right level of CO2.

There are a few ways you can inject CO2 into beer. In-line carbonation refers to the injection of CO2 into flat beer as it’s being poured into a vessel — often the bright tank. Some gas injection methods combine nitrogen (N2) with CO2, or use N2 on its own. Guinness Draught is likely the most popular example of a nitrogenated beer — the smaller bubbles produced by N2 allow for the thicker, silkier mouthfeel of many stout beers.

Brewing Equipment and Technology

Bulk CO2 systems have enormous benefits for commercial breweries looking to keep up with production and expand their market reach. Technology plays a key role in maintaining optimal CO2 levels for consistent beer quality, and Perfect CO2 supports large-scale operations with robust beverage carbonation solutions.

Draught systems must also maintain the brewer’s precise carbonation levels. Dispensing systems use CO2 to help move the beer from the keg out of the tap — using air compressors introduces too much oxygen to the beer, significantly impacting its taste and quality. The best solution for draught systems is a nitrogen separator to produce the ideal mix of gasses for dispensing beer.

The benefits of a nitrogen separator include:

  • Perfect carbonation results in greater beer profits
  • Eliminate rising costs of mixed gas and nitrogen cylinders
  • Completely hands-free operation
  • Wall-mounted design features a touch-screen user interface for ultimate operation communication
  • Safer, cleaner and easier than beer-gas and nitrogen cylinders

Achieving the perfect pint comes down to how you leverage your equipment to get the best results. To keep your brewery profitable, you must have the right mix of gasses in your dispensing system. A Gas Expert can help you calculate the gas mix and temperature conditions for your beer dispensing system.

Beer Carbonation FAQs

These are some of the most frequently asked questions concerning beer carbonation:

How Tall Should the Head on Your Finished Beer Pour Be?

To maximize your kegged beer profits and to provide the best customer satisfaction, a 16 oz pint glass should have a 3/4-inch head. The head on a pint of beer increases aroma and provides a nice mouth feel for greater customer satisfaction. The head on a pint also saves approximately 1.5 oz of beer on each pint poured. A perfect pint equals maximum profit!

What’s the Ideal Temperature for Your Keg Cooler?

As a general rule of thumb, beer kegs should be stored at a consistent 38 degrees Fahrenheit. If warmer or colder beer dispense is desired, please contact one of our Beverage Dispense experts to advise you on how to accomplish this without causing flat or foamy beer. In most cases, mixed gas from Nitrogen Separators can help compensate for temperatures outside the normal range.

How Often Should You Clear Your Draught Beer Lines, and Why?

All recognized beer institutions agree that draught beer lines should be cleaned every two weeks. Proper beer line cleaning is essential for maintaining fresh and correct-tasting draught beer. Improper cleaning frequency and/or cleaning methods can increase beer foam and will make it difficult to achieve the Perfect Pour. As your beverage gas supply partner, Perfect CO2 Beverage Carbonation can assist you in finding reputable beer line cleaning companies in your local area.

Does It Really Matter What Gas and Pressure You Use on Your Beer Kegs?

Absolutely! The correct gas mix and gas pressures will dictate the profitability of your draught beer system. Improper gas types or mixes and incorrect gas pressures will cause undesirable outcomes, including over-carbonation, foamy beer, flat beer and general customer dissatisfaction. Contact one of our Beverage Gas Experts to find out what gas and pressure is perfect for your establishment.

Is the Mix of 25% CO2 and 75% Nitrogen Right for Your Non-Stout Beers?

While 25% CO2 is perfect for your stout creamed beers, it is absolutely not acceptable for any normal ale or lager type of beer. The result will be under carbonated or flat beer.

The perfect ratio of CO2 to nitrogen is customized for your exact draught beer system. Typically, 60%-80% CO2 will be the range for most long-drawn beer keg systems. Each beer system has its own ideal mix ratio to deliver the perfect pint. Our Gas Experts can calculate your ideal gas mix and assist you in how to increase your draught beer system profits.

Why Should You Use a Nitrogen Separator Over Changing, Ordering and Storing Cylinders?

Simple! Nitrogen Separators provide perfectly carbonated beer and wine for greater beverage profits. Separators also offer a much less carbon-intensive means to deliver nitrogen for beer and wine dispensing systems. Separators provide hands-free operation and customized gas blends for all types of keg dispense systems. Perfect Pints equal maximum profit!
