Tank beer – “tankova” – may be a hot new trend in London, with Meantime in Greenwich and Pilsner Urquell delivering fresh unpasteurised beer to pubs in beautiful shiny big containers, but the idea of putting beer in cellar tanks to deliver better quality is, even in London, more than a century old.
The first “tank” beer system in the capital appears to have been introduced by Hugh Abbot, a brewer at Watney’s original Stag brewery in Pimlico, London, just around the corner from Buckingham Palace. In 1913 he had three standing butts fixed up in the cellar of a Watney’s pub, and beer delivered in an old horse-drawn tank wagon of the sort that brewers used to transport beer to their bottling stores. The experiment was successful enough that by 1920 Watney’s had electric-powered tanker lorries, fitted with copper tanks, taking beer around to its pubs. It was still using electric vehicles in 1949, though by then tank deliveries to pubs were done using trailers mounted behind standard tractor units.
Another of London’s “big seven” 20th century brewers, Charrington’s, of the Anchor brewery in Mile End, was also delivering tank beer by the early 1920s, and a Charrington’s brewer, Alfred Paul, described the system to the Institute of Brewers in a talk in May 1922. Only “bright” mild beer, chilled and filtered, was delivered by Charrington’s tankers to its pubs, he said, although “experiments are being made with a tank for the bulk delivery of naturally conditioned beer.” The road tanks, made of copper lagged with iron, had a capacity of 24 barrels each, that is, 864 gallons, and the tanks in the pub cellars generally held three barrels each. “On arrival of the delivery tank, or road tank, at the house, the hose, is let down through the cellar-flap or any other available aperture, and the beer allowed to run down into the cellar tank. Should the fall from the street to the cellar be insufficient, a band-pump attached to the foot-board of the chassis could be used.” Charrington’s cellar tanks were generally made of earthenware, Paul said, being upright, cylindrical vessels, with a glazed inside, but ” experiments are now being carried out with aluminium and glass-lined steel.” The tanks, he said, “are carefully examined prior to filling, with a powerful electric torch. The men, who are carefully selected, are definitely instructed not to fill a tank unless, in their opinion, which by constant practice has become expert, the tank is scrupulously clean.”
