How important is beer gas in a home brew?

There’s nothing better to come home to after a long day’s hard work than an ice-cold beer. But imagine being able to enjoy a beer you've brewed yourself! If you'd like to brew your own beer at home but have no idea where to start, London Gases can help. Here we explain the importance of gas when brewing beer and how to use it.

Why use beer gas?

Beer gas is important when making homebrews as it's responsible for the small bubbles which create the froth that is characteristic of renowned beers such as Guinness. This adds to the overall sensation of the beer, making for a creamier consistency and a longer-lasting foam head. There are plenty of other benefits of using gas beer too, including a decrease in pouring costs and the retention of the original beer flavour.

What does beer gas do?

Beer gas isn’t just one singular gas – it's made up of a mixture of Co2 and nitrogen, the proportions of which can vary. It's important to get this ratio right to ensure your beer doesn't go flat. For example, a 25% carbon dioxide and 75% nitrogen blend is suitable for stouts, but not for regular lagers or IPAs, which need more Co2.

To ensure your beer doesn't go flat, the gas also needs to be added to your solution at high pressure. However, don't be fooled into thinking that the whole process requires high pressure, as for carbonation to take place, lower volume levels, around 1.8, are ideal. This whole process should take place within the keg, as beer gas is also used in the dispensation of your brew. Brewing your own beer requires a lot of hard work and knowledge, so don't expect to get it right on your first attempt.
