SafLager W-34/70 (German Lager)
The World's Most Popular Lager Yeast • Weihenstephan Heritage • Clean, Crisp Precision
SafLager W-34/70 is the most widely used lager strain on earth — the famous Weihenstephan 34/70 culture that ferments a remarkable share of the world's commercial lagers. It is prized for delivering pure, clean, crisp lager character with the consistency only a century of selection can produce.
With 82% attenuation and high flocculation, W-34/70 ferments thoroughly for a dry, refreshing finish and then drops brilliantly clear — the textbook German lager profile.
Flavor & Aroma Profile
- Exceptionally clean, neutral lager fermentation
- Crisp, dry finish with refreshing snap
- Delicate floral and subtle sulfur notes that condition out
- Transparent profile that showcases pilsner malt and noble hops
- Balanced, smooth drinkability
Fermented cold, W-34/70 is immaculately clean and classically German; it also tolerates warmer fermentation better than most lager strains, staying respectable into the mid-60s°F when temperature control is limited.
Brewing Applications
SafLager W-34/70 is a staple ingredient in virtually every lager style, including:
- German Pilsner
- Helles
- Munich Dunkel
- Märzen / Oktoberfest
- Bock and Doppelbock
- Schwarzbier
- American Lager
It is also the safest single answer to the question of which yeast to use for any lager, anywhere.
Usage Recommendations
Pitch two 11.5 g sachets into 5 gallons of lager-strength wort for a proper cold-fermentation cell count, fermenting at 53–59°F. The cold end produces maximum crispness and cleanliness; the warmer end speeds fermentation with minimal character cost.
After fermentation, hold a brief diacetyl rest around 62–65°F, then lager cold for two to four weeks for true German polish.
Specifications
- Attenuation: 82%
- Flocculation: High
- Fermentation Temperature: 53–59°F
- Format: 11.5 g dry sachet
- Beer Styles: Pilsners, helles, Märzen, bocks, dunkels, American lagers
Whether you're crafting a snappy German pils, a malty Oktoberfest, or your very first lager, SafLager W-34/70 delivers the clean, crisp fermentation that made it the world's standard.
