butts

The butt was a measure of liquid volume equalling two hogsheads. This equated to 108 imperial gallons (490 l) for ale or 126 imperial gallons (570 l) for wine (also known as a pipe).

lasts

The English last could also be understood as the volume occupied by the other lasts. In some sources, the last is equated with 640 gallons. The beer last was 12 barrels, the cod last and some herring lasts were also 12 barrels, and the pitch last was 12 or 14 barrels.
