About the strain

Rooted in the brewing heritage of Norwegian farmhouse ales, our Multi-Strain Kveik Yeasts are crafted blends of authentic kveik cultures. Each strain contributes its distinct character, creating a rich, complex and layered flavor at high temperatures. At lower temperatures you can expect a more neutral flavor profile. Depending on the temperatures our yeast will ferment in 2-10 days.

About fermentation

Voss ferments well from 15°C/ 59°F and up to 40°C/ 104°F. The higher fermentation temperature, the faster fermentation. At the optimum temperature (31-35°C) expect fermentation to finish in 72 hours. When fermentation is done at low temperatures you can expect fermentation time to increase. For high gravity beers, we recommend users to pitch two packs of yeast and add yeast nutrition to ensure healthy fermentation. Pitch directly into wort by sprinkling it across the surface or rehydrate yeast. For fermentation below 18°C/ 64°F, or high gravity, increase pitching rate to 60 g/HL. Sealed packages should be stored in dry conditions below 6°C (43°F). Product can be transported and kept at room temperatures for a period of up to 1 month. Opened bags must be re-sealed and stored in dry conditions below 6°C (43°F) and used within 3 days. Do not use damaged sachets.

About Origin

The Voss kveik comes from Sigmund Gjernes in Voss, Norway. Voss is situated south of the Jostedal glacier. Voss was somewhat isolated from the larger cities, and most people were farming and self-sustained. People shared kveik mainly with each other, and because of the distance to other settlements, the kveik was rarely mixed with other types. The Voss kveik is unique in taste and aroma, much because of the great work done by Sigmund and others to preserve the yeast throughout the years.
