Hornindal Kveik Yeast | Omega Yeast OYL-091
Omega OYL-091 Hornindal Kveik Yeast for Tropical, Fast-Fermenting Ales
Omega Yeast OYL-091 Hornindal Kveik is a Norwegian farmhouse strain for brewers who want bold tropical fruit character, broad temperature flexibility, and very fast fermentation performance. It is a strong choice for hazy IPA, American IPA, pale ale, fruited ales, and other beers where expressive citrus and tropical fermentation notes can work with modern hop character instead of fighting it.
Based on Omega's published guidance and current technical references, this strain typically delivers 75% to 82% attenuation, high flocculation, up to 16% ABV tolerance, and a recommended fermentation range of 68 to 95°F. It is also handled here as a non-phenolic, non-diastatic, STA1 negative kveik strain suited to fast, fruit-forward ale fermentations.
What Omega OYL-091 Contributes to Beer
- Bold tropical expression: Pineapple, mango, and citrus-like fermentation notes can reinforce modern hop profiles
- Fast warm-temperature performance: Useful when you want aggressive turnaround without sacrificing character
- High flocculation: Supports practical clarification and yeast handling despite expressive fermentation
- Strong gravity tolerance: Helpful in bigger hop-forward beers and other stronger ales

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.
