I'm much intrigued by the passage on "carbonated ale", an early from of tank beer.
"In London and some of the other large towns beer is supplied through a tube, or a hose, from a tank cart or motor into a receiver. This beer is suitable only for a quick sale, say forty-eight hours, and is ready to sell at once, is always bright and clear to the last drop, and has no deposit.
Thus the paraphernalia connected with barrels, and the care requisite in the treatment of beer in barrels, are avoided.
This beer is known as carbonated ale, and no waste ought to occur.
Beer so brewed is as good the day it is received as it will ever be, and, no doubt, saves a great deal of labour, anxiety and care, but these chilled and filtered beers, both in cask and bottle, have not the keeping qualities of beer naturally conditioned.
They are, however, so much limited to a few areas, that we must learn also all about the treatment of beers in cask."
"The Art and Practice of Innkeeping" by Alexander F. Part, 1922, pages 198-199.
This is one of the earliest mentions I've found of non-cask-conditioned beer in Britain. Though Worthington did experiment unsuccessfully with beer brewed to the "American system" (i.e. carbonated) before WW I.
