Omega OYL-107 Oktoberfest Yeast for Märzen, Festbier, and Malt-Forward German Lagers
Omega Yeast OYL-107 Oktoberfest is a lager strain for brewers looking to build smooth, malt-driven German lagers with clean fermentation and classic seasonal character. It is a strong fit for Märzen, Oktoberfest, Festbier, and related lager styles where bread crust, toast, and rounded malt depth should stay in front while the finish remains polished and drinkable.
Based on current technical references tied to this product, the strain is typically listed at 73% to 77% attenuation, medium to high flocculation, up to 9% ABV tolerance, and a recommended fermentation range of 46 to 58°F. A diacetyl rest is still a smart step for brewers chasing the cleanest possible lager finish.

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.
