The carbonation can occur before or after bottling the beer. If the beer continues fermenting in the bottle, then it naturally carbonates and the head is formed upon opening and pouring the beer. If the beer is pasteurized or filtered then the beer must be force carbonated using pressurized gas.
Beer may also be force-carbonated using a keg and special bottling equipment so that the carbonation level can be carefully controlled. Carbonation is often achieved with approximately 4 ounces (110 g) of corn sugar boiled in 2 cups (500 mL) of water then cooled and added to a typical 5-US-gallon (19 L) batch before bottling. [71]
The process of filtering removes carbonation and means the beer requires force carbonation. [1] Mechanical filtering and pasteurisation of bottled beer started at the end of the 19th century. The first beer known to have been mechanically filtered and force carbonated as draught keg beer was Watneys Red Barrel in 1931.
This means that the beer has smaller bubbles and a more creamy and stable head. [6] These less soluble inert gases give the beer a different and flatter texture. In beer terms, the mouthfeel is smooth, not bubbly like beers with normal carbonation. Nitro beer (for nitrogen beer) could taste less acidic than normal beer. [7]
Such beer is known as bright beer and requires force carbonation before bottling or serving from a keg. [1] In the United Kingdom, a beer which has been filtered in the brewery is known as "brewery-conditioned", as opposed to unfiltered bottle-conditioned and cask ales. [2]
The beer contains about a third more hops, and nearly double the amount of roasted barley than Guinness Draught. [23] [24] The beer is force carbonated. [19] The beer has 47 Bitterness Units. [23] Guinness have used a slightly different variant of their yeast to brew FES since 1960. [1]
A 16th-century brewery Brewing is the production of beer by steeping a starch source (commonly cereal grains, the most popular of which is barley) in water and fermenting the resulting sweet liquid with yeast. It may be done in a brewery by a commercial brewer, at home by a homebrewer, or communally. Brewing has taken place since around the 6th millennium BC, and archaeological evidence ...
The most common size of Cornelius keg holds 5 US gallons (19 liters) which conveniently matches the size of a typical batch of home-brewed beer, and kegs can be used to carbonate the beer. [1] This means that rather than saving, cleaning, and filling approximately fifty bottles, the brewer only needs to fill one keg.
