The London Ale strain is a high attenuator that has obvious English character in its pronounced minerality and mild fruit notes. It performs best for dry, crisp beers, and in highlighting hop bitterness. For more neutral strains, try West Coast Ale I (OYL-004), or keep the English deportment with British Ale I (OYL-006) or British Ale VI (OYL-013).

A Characterful English Ale Yeast for Crisp, Balanced Beers

Omega Yeast OYL-003 London Ale is a traditional English ale strain that combines reliable attenuation with distinctive British character. Known for its subtle fruit esters and characteristic minerality, this strain produces dry, crisp beers that allow both malt and hop character to shine.

Unlike softer English strains that can emphasise malt sweetness, London Ale tends to finish cleaner and drier, making it particularly effective in hop-forward styles where a crisp finish helps showcase bitterness and aroma.
