Omega OYL-015 Scottish Ale Yeast for Malt-Forward Scottish and British Beers
Omega Yeast OYL-015 Scottish Ale is a versatile ale strain for brewers who want high flocculation, solid attenuation, and a fermentation profile that supports malt character without stripping away style-defining depth. It is a strong fit for Scottish ales, malt-forward British styles, amber ales, and brown ales where the grist should stay central.
Based on Omega's published guidance and current retailer technical references, this strain typically delivers 73% to 76% attenuation, high flocculation, up to 10% ABV tolerance, and a recommended fermentation range of 63 to 75°F. It is also listed as non-diastatic and non-phenolic, making it a practical choice for clean, malt-aware ale fermentation.
What Omega OYL-015 Contributes to Beer
- Malt-supportive fermentation profile: Helps caramel, toast, and richer malt notes stay prominent
- High flocculation: Supports clearer finished beer and practical cellar handling
- Good temperature flexibility: Can stay relatively neutral cooler and develop more esters when pushed warmer
- Strong style versatility: Useful in Scottish ales and other malt-forward recipes

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.
