Tierce
From Wikipedia, the free encyclopedia
For other uses, see Tierce (disambiguation).
The tierce is an old English unit of wine casks, holding about 159 litres. From 1824 on it was defined by English law to be 35 imperial gallons, before that (and still in the USA) it was 42 wine gallons—the difference being less than tenth of a percent. It is closely related to the modern petrol barrel.
