BEAT THE HEAT: Homebrewing in the height of summer with Omega Yeast

Omega 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 these versatile kveik (“yeast” in
Norwegian) strains from the farmsteads of Norway available to homebrewers everywhere.
Whether you choose HotHead™ (OYL-057) to ferment a cleaner brew, or newly released
Hornindal Kveik (OYL-091) for intense, tropical flavors, you’ll be amazed by the wide versatility
that the Norwegian strains offer.

HotHead® (OYL-057, an OYL exclusive)
HotHead® is Norwegian in origin -- from the Stranda Kveik. The famous Lars of Larsblog
collected it in Norway and then sent it away for isolation. This isolate has a uniquely pleasant
fruitiness and an absurdly wide fermentation range, and ferments clean across the entire range.
This is great for brewers who want to be energy efficient with temperature control, or who lack
temp control in warm climates. It maintains a stable ester profile, and we advocate it to be used
for hoppy American ales. (non-phenolic).
Ø Flocculation: Med-High
Ø Attenuation: 75-85%
Ø Temp Range: 62-98° F (16-37° C)
Ø Alcohol Tolerance: 11% ABV

Voss Kveik (OYL-061)
Voss Kveik is also a Norwegian farmhouse strain (from the Gjernes farmhouse) which is new to
US brewers. Omega Yeast was the first to have this strain. It maintains character over a broad
range with subtle orange citrus notes that match fruity hops well. Best fermented warm! (non-
Ø Flocculation: Medium
Ø Attenuation: 75-82%
Ø Temp Range: 68-98° F (20-37° C)
Ø Alcohol Tolerance: 12% ABV

Hornindal Kveik (OYL-091, an OYL exclusive)
A wonderfully unique Norwegian “kveik” from the farmstead of Terje Raftevold, Hornindal
presents an intense, tropical flavor and aroma of fresh pineapple, mango and tangerine, which
complement fruit-forward hops. Add even more dimension to "C" hops with a high fermentation temperature, intensifying aroma and fermentation speed. Ferments well at 90+° F. (non-phenolic).
Ø Flocculation: High
Ø Attenuation: 75-82%
