—Robert Frost , "Directive"beer andale a firkin is equal to nine imperialgallon s or a quarter of a barrel (40.91481litre s). Casks in this size (themselves called firkins) are the most common container forcask ale .For
wine the firkin had a larger size, namely a third of a tun. A tun being 210 gallons in the UK and 252 fluid gallons in the US, thus a wine firkin is about 318 L (318.226 or 317.975). It is also called "tertian" or, preferably,puncheon (in the US also shortened to "pon").Butter andsoap used to be sold by the firkin, too. In these cases it was rather a measure of mass, 56 lb (25.4 kg) and 64 lb (29.0 kg) respectively.The term "firkin" is currently used to refer to antique wooden buckets, usually with wood handle and lid, about 10 inches (250 mm) high and 10 inches in diameter (about 10L or 2-3 dry gallons in capacity), formerly used to store sugar and other items.
