Saflager W-34/70 Lager Yeast

Saflager W-34/70 is one of the most widely used lager yeast strains in the world, renowned for its clean flavor profile, excellent attenuation, and ability to produce authentic German-style lagers. Originating from the famous Weihenstephan yeast strain, it delivers exceptional performance for both home and professional brewers.

This yeast is highly valued for its consistency, cold fermentation tolerance, and ability to emphasize malt and hop subtleties without overshadowing the overall character of the beer.

W-34/70 lager yeast produces elegant, well-attenuated beers with a crisp finish, subtle ester profile, and firm body. It forms a compact sediment after fermentation, helping improve clarity without filtration.

Technical Details:

• Flocculation: High, resulting in improved clarity and compact sedimentation.

• Attenuation: Medium to High, typically ranging from 80-84%, providing a balanced dryness.

• Alcohol Tolerance: Can handle ABV levels up to 9% with proper pitching.

• Fermentation Temperature: Best performance between 12–15°C (53–59°F), but can be fermented as low as 9°C (48°F) for traditional lagers.

• Usage: Pitch directly into cooled wort or rehydrate for optimal cell count and viability.

• Ideal Beer Styles: Excellent for Pilsners, Helles, Bocks, Märzens, Dunkels, and any style where crispness and smooth lager character are desired.
