How nexAir Helps Breweries Choose the Right Gases for Quality and Consistency

Brewing great beer involves countless variables, but one of the most overlooked factors might be sitting in plain sight: the gases used throughout your process. From purging tanks to packaging finished products, the quality and composition of your CO2 and nitrogen directly affect flavor stability, shelf life, and overall beer quality. Many breweries discover too late that subpar gas supplies have been undermining their carefully crafted recipes all along.

CO2: More Than Just Bubbles

Most brewers understand that CO2 creates carbonation, but its role extends far beyond putting fizz in your finished product. Food-grade CO2 serves as an inert blanket during fermentation, protecting your beer from oxygen exposure that can create off-flavors and reduce shelf life. During bright tank conditioning and packaging operations, CO2 displaces oxygen to maintain the fresh, clean flavors you worked so hard to develop.

The purity level of your CO2 matters enormously. Industrial-grade CO2 might contain trace contaminants like sulfur compounds or hydrocarbons that introduce unwanted flavors into your beer. Food-grade CO2 undergoes additional purification steps that remove these potential flavor killers, ensuring your gas supply enhances rather than detracts from your brewing efforts.

Temperature consistency during CO2 delivery affects carbonation levels and can impact your packaging efficiency. Fluctuating gas temperatures make it difficult to achieve consistent carbonation across batches, leading to quality control headaches and potential customer complaints about flat or over-carbonated beer.

Nitrogen Applications in Modern Brewing

Nitrogen has become increasingly popular in craft brewing, particularly for creating the smooth, creamy texture associated with nitro beers. Unlike CO2, nitrogen doesn’t readily dissolve in beer, creating smaller bubbles that produce a distinctive mouthfeel and cascading visual effect that many customers find appealing.

Widget cans and draft systems that dispense nitro beers require specific nitrogen blends, typically around 75% nitrogen and 25% CO2. Getting this mixture right affects both the dispensing characteristics and the final product quality. Too much nitrogen can make beer flat-tasting, while insufficient nitrogen won’t produce the desired texture and appearance.

Beyond nitro applications, nitrogen serves as an excellent purging gas for tanks and packaging lines. Its inert properties protect beer from oxidation without affecting carbonation levels, making it particularly useful for breweries that need to maintain products for extended periods before packaging or distribution.

Maintaining Excellence Through Partnership

Brewing exceptional beer requires attention to countless details, and gas quality represents one area where the right partnership can eliminate variables that might otherwise compromise your products. Working with suppliers who understand the unique requirements of brewing operations helps ensure that gas-related factors support rather than hinder your quality goals, allowing you to Forge Forward with confidence in your finished products.
