What do gas blenders in a draft system do?

Gas blenders in a draft system are specifically responsible for mixing different types of gases, typically a combination of carbon dioxide and nitrogen. This is essential in achieving the desired carbonation levels and mouthfeel of the beer. The use of various gas types allows for flexibility in serving different styles of craft beer, as some beers benefit from a higher nitrogen content to create a smooth, creamy texture, particularly nitro stouts, while others are best served with a standard CO2 mix.

This function ensures that the beer pours correctly, with the right amount of carbonation, which influences flavor and aroma. Proper gas blending is crucial for maintaining the quality and integrity of the beer throughout its service life. Understanding this aspect of draft systems is vital for those working in environments where beer is served, ensuring that customers enjoy beverages as intended by the brewer.
