Description
A Burton-upon-Trent classic that leans mineral and dry, keeping the spotlight on malt and hops rather than on itself. Warmer ferments coax out light orchard and stone-fruit esters. It wants sulfate-rich brewing liquor; very soft water tends to leave it sluggish. Suits bitters, porters and barleywines alike.
