Ways to distribute Draught Guinness
Over the years, we have had many people asking for the proper way to serve Guinness, and as a result of that, we have decided to enlighten people with this short article. In the USA, there are mostly three types of Guinness from Ireland; one is bottled, bitter and has a very high alcohol level, the other is the type drawn from a keg, mostly found in restaurants and bars all over the country. Some of the reasons this type of Guinness is being sought after is that its alcohol level is low, and it is also low in calories. The tight and creamy surface of the foam it produces when poured distinguishes it from the others. Guinness is also distributed in 14.9oz canisters found in stores. This version is as close as it gets to the draught version as the canister was designed to have a little nitrogen rush at the bottom released on opening the can.
For this article, however, our primary focus is on the second type- the type drawn from a keg. There is a pronounced difference between this kind of Guinness and the others. Some of the differences are
1. Unlike the other kind of beers where CO2 is used to propel the beer through the lines, the Draught Guinness beer uses a nitrogen and CO2 combination. This combination is a mixture of 25% CO2 and 75% nitrogen. The regulator on the gauge of the tank is also set at 35 psi ± 3 psi. The function of the nitrogen gas in the combination is to give it that tight and creamy foam surface that distinguishes it from the rest.
To achieve the desired results, The Guinness Import Company makes sure that the air tanks used by the gas traders contain the right proportion of mixed gas as some traders either usually fill a CO2 or nitrogen receptacle with the Nitrogen and CO2 combination. In situations like this, a CO-Nitrogen Adapter can be used to regulate the amount of nitrogen gas or CO2 gas in the tank.
2. The Keg Coupler. The coupler is the component that is connected to the keg and allows extraction of the beer to take place.
3. The Stout Faucet. The last noticeable difference between the Draught Guinness and the other beers is the faucet used. It differs from the common ones and sometimes referred to as the European Specialty Faucet. The handle of this faucet is different from the rest, and it has to be pulled forward first and then down before the beer comes out from the keg. It also has a restrictor disc from which the draught beer is made to pass through. The restrictor disc gives its tight and creamy foam head. With this faucet, there is no spillage or wastage while dispensing the beer.
