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. Flocculation is very high producing clear beers without filtration or use of process aids.
Brewing Properties
In Lallemand’s Standard Conditions Wort, LalBrew® Voss Kveik Ale yeast exhibits:
The 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)
Lag phase, total fermentation time, attenuation and flavour are dependent on pitch rate, yeast handling, fermentation temperature and nutritional quality of the wort.
Our research suggests that pitching LalBrew® Voss directly into wort without prior rehydration will often result in better performance including shorter lag-phase and greater attenuation.
