From Wikipedia, I thought this common knowledge, but apparently not.
Hogshead . The hogshead of beer and ale was equal to a quarter of a tun, half a butt, a barrel and a half, or three kilderkins. This unit is close in size to the wine hogshead . In the mid-15th century the ale hogshead was defined as 48 ale or beer gallons (221.8 L).

There’s a lot of moisture in packaged cold cuts, roast beef, ham, turkey - I used to buy it, separate slices and put on paper towels, roll up, and refrigerate. That was for the benefit of Mr. Salinqmind who liked it that way :-p. Cold cuts don’t freeze well, they’re too full of preservatives and get all soggy.
