A Barrel is a specific size , cask or keg is the generic for a container
of cask beer, it depends where you are drinking but Holts pubs in
Manchester are known to do 36 Gallon casks( I think this a barrel) ,
some pubs with great ranges of beers stock 9 gallons casks, This is in
the UK.

: 1 hogshead 
That's just great -- now perhaps you can explain a phrase that has
mystified me since 1967:
....dancing through a hogshead of real fire...
Perhaps it is like jumping thru a "ring of fire," . . .
ah . . . a belated virtual one minutes silence for the man in black's passing?
then altogether -
"Love Is A Burning Thing
And It Makes A Fiery Ring
Bound By Wild Desire
I Fell Into A Ring Of Fire
I Fell Into A Burning Ring Of Fire
I Went Down, Down, Down
And The Flames Went Higher
And It Burns, Burns, Burns
The Ring Of Fire"
