Beer Gas Exchange
Fear not! We have Beer Gas.
25/75 gas—also known as "The Guinness Mix" or Beer Gas—is a pre-mixed blend containing 25% CO2 and 75% nitrogen in a single cylinder.
This blend was created to dispense nitrogen-infused beers like Guinness Stout but has been widely applied to other beers.
Applying 25/75 gas to regularly carbonated beers makes them go flat.
Nitro Beers are Different
So-called “nitro beers” are injected with Nitrogen during the brewing process to create their impressive foam and settling appearance.
They contain very low levels of carbonation - less than ½ that of normally carbonated beers.
Nitro beers become over-carbonated and foamy if dispensed with straight CO2 and thus require a dispense gas with a lower percentage of CO2.
(Nitro beers contain 1 to 1.4 volumes of CO2, depending on the brand. Normally carbonated beers contain 2.3 to 2.8 volumes of CO2 and some beer styles contain up to 4.0 volumes of CO2).
We sell and exchange tanks of beer gas in the store. Our tanks contain 20 cubic feet of beer gas.
Beer gas requires the use of a nitrogen regulator, which we sell here: nitrogen regulator
