In November 1799 a brief paragraph appear in the Times newspaper:
“A Porter Brewery is about to be established at Portsmouth, by a number of opulent Gentlemen, who have subscribed £5000 each. The Thames water for this undertaking is to be conveyed by shipping.”
The reason for the appearance of the second sentence is that many drinkers, at the time, were convinced that good porter, then easily the best-selling beer in London, and perhaps the most popular style in the British Isles, could only be brewed with water from the Thames. The “opulent Gentlemen” behind the proposed Portsmouth venture clearly felt that if they could say their porter was made with Thames water, it would give them instant credibility.
In fact, although several of the big London porter breweries stood by the banks of the Thames, including Barclay Perkins in Southwark, Calvert’s Hour Glass brewery almost directly opposite Barclay Parkins on Upper Thames Street in the City, and Hoare’s by St Katharine’s dock, even the Thames-side ones took their water from wells, or, like Whitbread in Chiswell Street, on the northern edge of the City, from reservoirs supplied by the New River, constructed in the 17th century to bring water to London from near Amwell in Hertfordshire.
In the “pre-scientific” era, writers on brewing knew that different waters had different effects on the final brew, and regularly recorded myths about which waters were best. A brewing book from 1719, A Guide to Gentlemen and Farmers for Brewing the Finest Malt Liquors insisted that “Upon the whole, the best Liquor to Brew with, is that which is taken from a small clear Rivulet or Brook, undisturb’d by Navigation or Fording,” though
“Possibly much the best Water in England is that at Castleton in Derbyshire, commonly called, The Devils Arss, Which Owzes from a great Rock, covered over with a shallow Earth … I have seen the Ale made of Castleton-Water as clear in three days after it was Barrelled, as the Spring-Water it self, and impossible to be known by the Eye in a Glass from the finest Canary Wine.”
Some had preferences that seem frankly bizarre today. A book called A Treatise on the Brewing of Beer, self-published in 1796 by one E Hughes of Uxbridge, declared that when it came to brewing liquor: Continue reading A short history of water
