Voss

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.

USING VOSS

Voss is a robust multi-strain kveik culture suited to a broad range of brewing conditions. Its fast fermentation performance and broad temperature tolerance make it a flexible choice for different production environments. Fermentation behaviour will vary with temperature, pitch rate and wort conditions.

STORAGE & HANDLING

Store sealed packages in dry conditions below 6°C / 43°F. The product can be transported and kept at room temperature for up to one month. Opened bags should be re-sealed, stored dry below 6°C / 43°F and used within three days. Do not use damaged sachets.

ABOUT THE ORIGIN

Voss kveik originates from the Voss region in Western Norway, an area with a long and well-preserved farmhouse brewing tradition. The culture has been maintained through generations of local brewing, where yeast was collected, preserved and reused from one brew to the next.
