JY311 - River Thames

JY311 is a timeless British ale yeast strain originating from one of the Thames breweries.This strain is a favorite for brewers crafting authentic English-style ales due to its robust character and alcohol tolerance. JY311 delivers a harmonious blend of soft fruit esters—think apricot and pear—with a delicate malt sweetness, rounded out by a clean, slightly tart finish. Its versatility makes it perfect for Bitters, ESBs, and Porters, where it enhances malt complexity while allowing subtle hop notes to shine. With moderate attenuation and flocculation, JY311 produces a clear, well-balanced beer that’s both approachable and full of character, evoking the charm of a classic UK pub pint. This strain likes moderate hardness of water, so keep your mineral content in check.
