Omega OYL-012 Pacific NW Ale Yeast for Clean, Hop-Friendly American Ales
Omega Yeast OYL-012 Pacific NW Ale is a versatile ale strain for brewers who want a relatively clean fermentation profile with subtle fruit, good flocculation, and enough neutrality to let hops and malt stay in focus. It is a strong fit for American pale ales, IPAs, amber ales, brown ales, and other styles where balance matters more than a heavy yeast signature.
Based on Omega's published guidance and current retailer technical references, this strain typically offers 67% to 71% attenuation, high flocculation, up to 10% ABV tolerance, and a recommended fermentation range of 65 to 75°F. It is also listed as non-diastatic and non-phenolic, making it a useful choice for clean American ale fermentations.

Liquid Yeast Storage and Shipping
We store liquid yeast in temperature-monitored refrigeration to help preserve 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, route, 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.
