Firkin

Firkin A firkin is a small cask used for liquids, butter, salt, and other commodities. The term is derived from the Middle Dutch word 'vierdekijn', meaning 'fourth', as it is a fourth of a barrel. The size and capacity of a firkin can vary depending on the commodity it is used for.

History

The firkin has been used since the Middle Ages and was a common unit of measurement in the United Kingdom and other parts of Europe. It was primarily used for ale, beer, and other liquids, but also for dry goods like butter and salt.

Measurement

The capacity of a firkin varies:

• For ale or beer, a firkin is equal to 9 imperial gallons or approximately 40.9 liters.
• For butter and other dry goods, the size can vary, but it is generally around 56 pounds.

Usage

Firkin casks are still used today, particularly in the brewing industry. They are often used in the production of cask ale, where the beer undergoes secondary fermentation in the cask. This traditional method is popular in British beer culture.
