West Coast Ale II | Omega Yeast OYL-009
Omega OYL-009 West Coast Ale II Yeast for Clean, Slightly Fruity American Ale Fermentation
Omega Yeast OYL-009 West Coast Ale II is a clean American ale strain for brewers who want reliable attenuation, good flocculation, and a slightly fruitier expression than the classic West Coast Ale I profile. It is a strong fit for pale ale, IPA, stout, porter, and other American styles where you still want hops and malt to lead, but with a touch more fermentation character and a softer edge than a fully neutral workhorse strain.
This strain is commonly positioned as clean, easy clearing, and moderately expressive, with subtle citrus and light fruit character that can show more clearly as fermentation temperature rises. That makes it useful for brewers who want a dependable American ale yeast that still brings a little personality to the glass.

Why Brewers Choose OYL-009

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.
