I believe I did 7 brewery tours in 10 days, followed by the GBBF. One
thing about British beer... I simply can't get tired of it. I never
get "beer burnout" as I often do at the American Homebrewers Association
conferences. Incidentally, I have photos from some of those brewery
tours on my website. I plan to add more... I've got photos from over
two dozen breweries... just keep reminding me via email.

That's not correct. Only a small portion of Samuel Smith's casked beers
are in wood casks... most is in metal casks. I have also seen Marston's
in metal casks (at the GBBF, for example, where I worked as a steward in
1997 and at the Real Ale Festival here in Chicago).

That may be true, but you simply cannot find British oak anymore (at least
not some that anyone would cut down and make into anything). There may
be no difference between British and American oak, but there certainly is
a difference between American and European oak (Limosin and Klaipeda (Memel)).
I have tasted beer made in new American Oak casks (mine) and new French
(Limosin) Oak casks... the French was barely oaky and the American
*intensely* oaky after barely a week! I also have several British brewing
texts which specifically say that casks made from American white oak are
not acceptable for making casks due to the flavour it imparts to the beer.
They specifically said that English and European oak *was* acceptable
from a flavour perspective and that the main difference between English
and European oak is that one was straight enough to be split and the other
had to be sawn (don't recall which was which).
American distilleries use *charred* oak. There was absolutely *no* charring
in Samuel Smith's casks (I actually spent some time in their Coopers' Room).
I'm also pretty sure there isn't any charring in any of the other breweries'
wooden casks. Even wine casks are not charred... some are toasted, but this
is different from charring. No... none of the beer casks I'm aware of are
Incidentally... if you recall I was following up on John Isenhour's
post on how quickly you must consume a cask, I stubmbled upon one
source for that info:

I'm sure they are well aware of the difference between American white and
red oak... you see... soft spiles (the pegs you use to vent excess CO2
from cask-conditioned beer) are made either from bamboo or *American RED
oak*. The soft spiles I brought back from the UK happen to be made from
American red oak. I have hard spiles (which you use when the venting is
complete) made from both wood and plastic.

Traditional cask sizes are: pin (4.5 imperial gallons), firkin (2 pins),
kilderkin (two firkins), barrel (two kilderkins), hogshead (1.5 barrels
or 54 imperial gallons), puncheon or tertian (2 barrels or 72 imp gallons),
pipe or butt (3 barrels or 108 imp gallons) and tun or ton (2 pipes or
an amazing 216 imperial gallons!). Ships' tonnage is based on how many
ton/tun casks of beer they could hold.
Actually, there's a lot of info that might be useful for this list at:
