I’ve done an analysis like this before, but it’s worth repeating in the light of the recent highlighting of the widespread quality issues with cask beer. The latest edition of the Cask Report states than one in seven pints sold in British pubs is now cask. According to the British Beer & Pub Association, total on-trade beer sales in the year to the end of June 2018 were 12.549 million bulk barrels. One-seventh of that is 1.793 million barrels. CAMRA’s WhatPub website states that there are 35,777 pubs in the country serving cask ale.
Even if we ignore sales to clubs and beer festivals, that means that the average pub sells 50 barrels a year, or just under one a week. That’s 276 pints a week, or a mere 40 per day. Assuming that beer is generally sold in 9-gallon firkins, that means the average pub can only have two cask lines if it wants to make sure it empties a cask within three or four days. Yet how many handpumps does the typical cask pub you go in have? Considerably more than two. And we wonder why so much beer ends up in poor condition.
