JY324 - Canterbury

Heritage English ale yeast from the heart of Kent.

JY324 is a single-strain heritage English ale yeast, widely regarded as the house strain behind classic Shepherd Neame-style bitters. Perfect for brewers chasing authentic Southern English character, it delivers a balanced, sessionable profile with moderate orchard-fruit esters, light phenolic spice (POF+), and the ability to attenuate deeply (often 78-83% in well-managed fermentations).

Expect a steady-to-vigorous fermentation that builds beautiful malt-hop synergy in high-mineral worts. Gentle notes of apple, pear and subtle peppery phenolic complexity emerge, paired with low-to-moderate sulfur that blows off cleanly during conditioning. Low flocculation leaves a pleasant, rustic haze — ideal for cask or unfined bottle-conditioned beers that carry that true hand-pumped pub charm.
