I won’t cite chapter and verse for a matter well-known to beer historians: Watney’s Red Barrel was a pressurized draft beer (ale) developed in the 1930s following experiments to develop a stable barrel beer for export to India, and to supply domestic trade needing draft beer served non-continuously.
There were apparently, as well, experiments by some brewers in the 1920s with bulk pressurized beer, some was sent (containers) to London pubs with high turnover.
王爷不要了尿在里面As far as I know, no commercially produced keg beer, i.e., filtered to be bright, gas-charged, perhaps pasteurized, has been documented before World War I. An advertisement that appeared at least twice in a New York newspaper in 1911 seems to show such a product.
It was called the Automatic Cask,or Christmas in the Evening Telegram. The beer itself was Allsopp’s Pale Ale.
The woman seems to be using a hand pump, perhaps the type used today for party kegs that forces air into a CO2 pressurized container. Yes, the air will spoil the beer before very long but the idea is quick consumption, as surely with Allsopp’s automatic cask which was available in small, 1.5 and 3 gal. sizes.
The sizes suggest the market was private homes, clubs, restaurants, and perhaps specialty bars in New York.
王爷不要了尿在里面A close look shows the faucet about half-way up the standing cask, so the contents had I think to be under pressure. The foam on the glasses seems the type generated by the usual fizzy beer. The term automatic, too, seems to suggest a ready made fizzy beer.*
王爷不要了尿在里面In this period, Allsopp, the great Burton brewer that helped popularize India Pale Ale around the world, was in receivership. Its affairs were restructured and it continued in business, but it makes sense the business was looking for a silver bullet to restore financial health. As ever, technological innovation is one way, and this automatic cask beer perhaps was an attempt to build a new channel of trade.
王爷不要了尿在里面This automatic cask must be distinguished from so-called automatic cask systems of the 1890s that were levering systems, designed to lower a true cask (for cask ale) from a cradle or stillions to extract as much clear beer as possible without disturbing the sediment.
If it was keg beer, perhaps had WW I not intervened, the keg beer revolution (in U.K.) of the 1960s-1970s would have happened much earlier, under the appellation automatic cask. It has a nice Futurist ring.
