German Bock Yeast | Omega Yeast OYL-111
This yeast is 40% off because it’s within at least one month of its best by date. We never ship expired yeast, but it may arrive near or just past that date. In our own lab tests, we've seen up to 85% viability beyond the best by date—much better than most calculators predict. It's a smart way to save without compromising your brew.
Omega OYL-111 German Bock Yeast for Rich, Malt-Driven Bock and Doppelbock Brewing
Omega Yeast OYL-111 German Bock is a lager strain for brewers who want to build rich, malt-forward German lagers with clean fermentation and a smooth finish. It is a strong fit for Helles Bock, traditional Bock, Doppelbock, and other fuller German lager styles where deep bread crust, toffee, and malt depth should stay prominent without muddy fermentation character.
Based on current technical references tied to this product, the strain is typically listed at 70% to 76% attenuation, medium flocculation, up to 10% ABV tolerance, and a recommended fermentation range of 48 to 55°F. That profile makes it a practical option for brewers targeting fuller-bodied lagers that still need clean structure and controlled finish.
What Omega OYL-111 Contributes to Beer
- Strong malt emphasis: Supports rich German lager profiles with depth and smoothness
- Clean lager finish: Keeps fermentation character restrained so darker or richer malt bills stay defined
- Good fit for stronger lagers: Useful in beers that need both body and polished fermentation
- Traditional German style alignment: Well suited to malt-centric lager brewing

This strain is a strong option when a brewer wants classic German lager behavior with more emphasis on malt richness and body than on high attenuation or a very lean finish. It helps build fuller lager styles that still ferment cleanly and present well after proper conditioning.
Liquid Yeast Storage and Shipping
We store liquid yeast in temperature-monitored refrigeration to help protect yeast health until shipment. Once in transit, weather and carrier handling are outside our control, so liquid yeast customers should choose shipping protection based on season, destination, and transit time.
Expedited shipping, insulated mailers, and ice packs can materially reduce risk for liquid yeast during warm-weather transit. Dry yeast is generally much less risky to ship than liquid yeast.
