Notes

Recommended for German Pilsner, helles, Dortmunder, Bock, any clean lager.

Character: Low ester, low higher-alcohol, neutral and balanced.

The most-brewed lager strain in the world, the Weihenstephan 34/70. Low esters and low higher alcohols make it the reference for a clean lager. It ferments a touch warmer than many lager yeasts, which shortens the schedule without adding fruit.
