Kveik yeasts are a distinct group of farmhouse yeast cultures used in Norwegian farmhouse brewing. These cultures came to be after decades of selection and usage in the typical high-gravity and high-temperature brewing applied in these farmhouse breweries. In current American brewing vernacular, "kveik yeast" refers to these specific yeast strains, either pure or as mixed culture.  Our catalog contains a combination of pure cultures as well as blends of kveik yeasts. All isolated and stocked from samples directly from Norwegian farmhouse breweries.

Our kveik strains have a very high temperature tolerance and produce clean esters without the undesirable fusel alcohols that are common with warmer fermentations in traditional British, and American strains.  Our kveik strains are non phenolic (POF-), producing a cleaner ester profile, compared to the phenolic flavors produced by Belgian ale strains at warmer temperatures.  At elevated temperatures (80°F - 105°F) our strains are ferment fast, flocculate hard, and exhibit above average alcohol tolerance.

JY224 - Arset Kveik Blend
Our Arset Blend produces an incredibly clean beer across the full range of fermentation temperatures.  The low ester production is ideal for fast fermenting porters, stouts, English IPAs, ambers or  light ales.  Soft notes of pear and apple flavors are noticeable on beers with low hop rates.  

Origin: Norway
Temperature range: 68°F-100°F
Flocculation: +++
Attenuation: 74-82%
Alcohol tolerance: 12%

JY246 - Hornindal
Isolated and selected for it’s tropical flavor and ester profile, especially at warmer temperatures, our JY246 kveik is a single strain isolate.  Mango, Pineapple, and guava are common descriptors for this strain, complimenting the more tropical hop varieties.  Hornindal shows medium to high flocculation but is well suited for hazy IPAs, creating relatively stable haze in beers brewed with high protein content grains (wheat and oats).  Dry-hopping during fermentation also improves the tropical flavors and haze stability. Non-phenolic

Origin: Norway
Temperature range: 75°F-100°F
Flocculation: ++++
Attenuation: 74-82%
Alcohol tolerance: 13%

JY247 - Voss Kveik 
Voss leans more toward citrus fruit flavors and aromas, compared to the tropical Hornindal strain.  Ideal for citrusy hop blends.  Another single strain isolate, NorVoss can be underpitched at the upper temperature range  to enhance the orange, lemon, and grapefruit flavors.  Voss produces a clean beer at the lower temp range, and is our top pick for clean seltzer fermentations. Non-phenolic

Origin: Norway
Temperature range: 70°F-97°F
Flocculation: +++
Attenuation: 75-83%
Alcohol tolerance: 13%

JY252 Arset Kveik Single
A single strain isolated from our Arset Blend, Arset Single highlights the subtle pear character of the JY224 blend.  An even cleaner version of the orginal Arset Blend

Origin: Norway
Temperature range: 68°F-100°F
Flocculation: +++
Attenuation: 74-82%
Alcohol tolerance: 12%
