How Gas Influences Beer Taste and Texture

When it comes to the taste of a pint, we all concentrate on the quality of the hops, malt, and barley, the amount of sugar, and the skill of the brewer. But did you know that the quality of the gas used to pump out the beer has a huge impact on how it tastes? 

It’s true! What gas a publican uses plays a major role in the taste of beer, cider, or ales. Whether you’re pouring from beer kegs or straight from a bottle, Gas Bottles Wimbledon has the low-down on what gas does to the taste of your pint. 

What Gas Is Used in Pubs?

The choice of gas that a pub uses depends on what beverages are being offered. Many establishments use a variety of gases to cater to diverse drink options. Gas selections are made based on the impact they have on the taste of various beverages.

Pubs usually use a mixture of carbon dioxide (CO2) and nitrogen gas.

100% CO2 Gas

The presence of carbon dioxide (CO2) in beer significantly influences its taste. The level of carbonation determines the beer's effervescence and mouthfeel, creating a dance of bubbles that enhances the overall drinking experience. 100% CO2 gas is known as pure cellar gas and is used for some lagers, ciders and soft drinks.

70/30% Mixed Gas

Combining 70% nitrogen and 30% CO2, 70/30 gas is used to dispense beers that aren’t quite as carbonated, like stout and bitter. The nitrogen is what gives these beers their distinctive creamy taste. 

60/40% Mixed Gas

60/40 is 40% nitrogen and 60% CO2. It’s used for lagers but most often it’s used to pump craft lagers and pale ales. If you dispense lager with 60/40 gas, it will eventually impair the taste of the beer.
