So how long did the ale last among 36 musos, not long, I bet?
That would be 2 pints each, or 1 per day, perhaps.
For those not used to the old beer measures:-

8 pints = 1 gallon
4.5 gallons = 1 pin
2 pins = 1 firkin
2 firkins = 1 kilderkin
2 kilderkins = 1 barrel
2 barrels = 1 puncheon
3 puncheons = 1 tun
6 firkins = 1 hogshead
2 hogsheads = 1 butt
2 butts = 1 ton
2 tons = 1 damn good piss up.
