About Firkins
A firkin (fir) ≈ 34.07 L (9 US gallons) - the most common cask for British real-ale delivery (9 imperial gallons = 40.91 L). A busy pub cellar cycles through several firkins per week. Craft breweries stage 'firkin tappings' of limited experimental ales. The name comes from Middle Dutch 'vierdekijn' (little fourth), as a firkin was one quarter of a barrel. 1 fir = 9 US gal ≈ 34.07 L.
About Cups
A cup = 8 fl oz = 16 tbsp ≈ 236.6 mL - the fundamental unit of American cooking. Almost every US recipe uses cups for dry and liquid ingredients. The US customary cup (236.588 mL) differs from the US legal cup (240 mL, used in nutrition labelling) and the metric cup (Australia/Canada: 250 mL). Kitchen sets come in 1/4, 1/3, 1/2, and 1 cup sizes. 2 cups = 1 US pint.
