Kveik is a Norwegian word meaning yeast. In the Norwegian farmhouse tradition, kveik was preserved by drying and passed from generation to generation. Kveik is the original, traditional dried yeast! The LalBrew Voss™ strain was obtained from Sigmund Gjernes (Voss, Norway), who has maintained this culture using traditional methods since the 1980s and generously shared it with the wider brewing community.
LalBrew Voss™ supports a wide range of fermentation temperatures between 25 – 40°C (77 – 104°F) with a very high optimal range of 35 – 40°C (95 – 104°F). Very fast fermentations are achieved within the optimal temperature range with full attenuation typically achieved within 2-3 days. The flavour profile is consistent across the entire temperature range: neutral with subtle fruity notes of orange and citrus.
In Lallemand’s Standard Conditions Wort, LalBrew Voss™ yeast exhibits:-
Fermentation that is completed in:
2 days at 40°C (104°F)
3-4 days at 30°C (86°F)
5-7 days at 25°C (77°F)
Medium to high attenuation and very high flocculation.
Neutral flavour profile across the temperature range with notes of orange and citrus.
The optimal temperature range for LalBrew Voss™ yeast when producing traditional styles is 35-40°C (95-104°F).
This is a POF Negative Strain.
Lag phase, total fermentation time, attenuation and flavour are dependent on pitch rate, yeast handling, fermentation temperature and nutritional quality of the wort.
