Here we have a fantastic yeast strain isolated from Sigmund Gjernes kveik (“Norwegian Farmhouse Yeast”) culture kindly shared by a traditional Norwegian homebrewer. A tasting panel noted flavors of orange and other tropical fruit when fermented at ~80°F/27°C with a clean finish. This strain is not very flocculant and should be great to use to add tropical notes to a NEIPA or another style. There are more experiments in progress to characterize the strain further and determine optimal pitch rates.  Note that this is not a true kveik which has multiple strains and sometimes bacteria. For more info on kveik, see Larsblog or kveik page on Milk the Funk.

Basic characteristics:

Attenuation: 77+% (more experiments in progress)
Flocculation: Low-medium (more experiments in progress)
Temperature Range: 72-95F / 22-35C (more experiments in progress)
Alcohol Tolerance: >8% (should be at least 13%, more experiments in progress)
Species: Saccharomyces cerevisiae
Diastaticus (STA1 gene) genotype: Negative

The pitches below contains either 1 gram of dried yeast that is enough for a 5 gallon pitch up to 1.060, or 6 grams that is enough for a 1 bbl pitch up to 1.060.  These packages come vacuum sealed and should be used within 3 months if left in the fridge (or should last years in the freezer).
