The ale kilderkin likewise underwent various redefinitions. Initially 16 ale or beer gallons (73.94 L), it was redefined in 1688 as 17 ale or beer gallons (78.56 L) and again in 1803 as 18 ale or beer gallons (83.18 L). kilderkin (Beer) Until the adoption of the imperial system the beer kilderkin was defined as 18 ale or beer gallons.
A carboy, also known as a demijohn or a lady jeanne, is a rigid container with a typical capacity of 4 to 60 litres (1 to 16 US gal). [1] [2] Carboys are primarily used for transporting liquids, often drinking water or chemicals. [3] They are also used for in-home fermentation of beverages, often beer or wine.
In 1824, these units were replaced with a single system based on the imperial gallon. [a] Originally defined as the volume of 10 pounds (4.54 kg) of distilled water (under certain conditions), [b] then redefined by the Weights and Measures Act 1985 to be exactly 4.546 09 L (277.4 cu in), the imperial gallon is close in size to the old ale gallon.
A hogshead of brandy was approximately equal to 56–61 gallons (0.255–0.277 m 3). [citation needed] Eventually, a hogshead of wine came to be 52.5 imperial gallons (238.669725 L) (63 US gallons), while a hogshead of beer or ale came to be 54 gallons (249.5421 L with the pre-1824 beer and ale gallon, or 245.48886 L with the imperial gallon).
A basic formula [4] to calculate beer strength based on the difference between the original and final SG is: A B V = 131.25 ( O G − F G ) {\displaystyle ABV=131.25(OG-FG)} The formula below [ 5 ] is an alternate equation which provides more accurate estimates at higher alcohol percentages (it is typically used for beers above 6 or 7%).
Both the 42-US-gallon (159 L) barrels (based on the old English wine measure), the tierce (159 litres) and the 40-US-gallon (150 L) whiskey barrels were used. Also, 45-US-gallon (170 L) barrels were in common use. The 40 gallon whiskey barrel was the most common size used by early oil producers, since they were readily available at the time.
Brew in a bag has revolutionised home all-grain brewing as batch sizes of 9 to 45.5 litres (2.4 to 12.0 US gal) of wort into the fermenter are easily employed without any compromising on quality or versatility. A typical brew session using BIAB is typically 3 hours, not including fermentation.
[7] [8] A US liquid gallon can contain about 3.785 kilograms or 8.34 pounds of water at 3.98 °C (39.16 °F), and is about 16.7% less than the imperial gallon. There are four quarts in a gallon, two pints in a quart and 16 US fluid ounces in a US pint , which makes the US fluid ounce equal to 1 / 128 of a US gallon.
