Omega Yeast OYL-004 West Coast Ale I is a liquid American ale yeast selected for brewing clean, hop-forward beers with a crisp finish and excellent clarity. Each 150 mL pouch contains approximately 225 billion cells, providing enough yeast for a standard 5-gallon batch while producing a neutral fermentation profile that allows hop and malt character to take center stage.
Modeled after the classic "Chico" yeast strain, OYL-004 delivers light citrus ester expression with a dry, balanced finish that complements a wide variety of American beer styles. With attenuation of 78–84%, strong flocculation, a fermentation temperature range of 64-72°F (18–22°C), and alcohol tolerance up to 12-14% ABV, this strain provides dependable fermentation performance and excellent clarity across a broad range of recipes.
Packaged as a liquid yeast culture, OYL-004 should be stored refrigerated between 33–38°F (1–3°C) and should not be frozen. Pitch cold into properly oxygenated wort and ferment within the recommended temperature range for best results. Use within four months for optimal viability, and consider preparing a starter when brewing higher-gravity beers or using older yeast.
Omega Yeast OYL-004 West Coast Ale I is ideal for IPAs, Pale Ales, Cream Ales, and other American-style ales where a clean fermentation profile is desired. Its neutral character, reliable attenuation, and excellent flocculation make it an excellent choice for homebrewers seeking consistent fermentation and bright, hop-forward beer styles.
