Kveik Yeast From Omega Yeast! Ferment At Higher Temps!

Omega Norwegian Kveik Strains

Omega Yeast Norwegian Kveik Strains

Omega Yeast first became aware of the Norwegian Kveik strains via Lars Marius Garshol’s blog where he shared not only the history of Norwegian farmhouse brewing but the strains he was using to brew traditional Norwegian farmstead beers. The fermentation temperatures cited were practically unbelievable — up to, and sometimes exceeding, 100°F!

Omega’s first thought was that they were either making terrible beer or that these were remarkable strains! But after they ran some experiments, Omega confirmed that these unique strains ferment well at 70°F or 95°F with little difference in ester production. Many experimental batches later, Omega Yeast has made this versatile Kveik (“yeast” in Norwegian) strains from the farmsteads of Norway available to homebrewers everywhere. Whether you choose Lutra™ (OYL-071) to ferment a cleaner brew, isolated from the Hornindal Kveik (OYL-091) or the tropical flavors of the ESPE (OYL-90), you’ll be amazed by the wide versatility that the Norwegian strains offer.

Lutra (OYL-071 Exclusive)

A shockingly clean yeast with unrivaled speed when pitched at 90°F (32°C). The strain is perfect for brewing a refreshing pseudo-lager without the lead time of a lager.


Ø Flocculation: Med-High
Ø Attenuation: 75-82%
Ø Temp Range: 68-95° F (20-35° C)
Ø Alcohol Tolerance: 11% ABV 

ESPE (OYL-090)

Espe offers a unique profile of lychee, pear, and tropical fruit cup. The strain bolsters the sweet aromatics of modern IPAs but is versatile enough for your flagship pale ale or seasonal brew. Espe is most expressive when fermented at 90°F+

Ø Attenuation: 75-80%
