K.22 Stalljen Kveik Pro is a multi-strain yeast directly from the Seljeset farm in Hornindal, north of the Jostedal glacier. Once self-sufficient and dairy, the farm raised its own animals and brewed its beers on site. The name “Stalljen” comes from the former family stable, now transformed into a craft brewery.
Unlike laboratory-isolated strains, this yeast retains a living culture, shaped by generations of farm brewing. It reflects an intact heritage, passed down in its natural diversity.
Stalljen’s aroma profile is highly versatile, depending on temperature. It combines notes of mango, pineapple, apple and ripe fruit, enhanced by a subtle touch of clove and anise. At higher temperatures, there’s a tiny, creamy, slightly caramelized nuance. This character may be linked to the farm’s dairy past.
During propagation, Kveik Yeastery stabilized the strain with precision. They have preserved the natural interaction between the original yeasts, guaranteeing a reliable, active and ready-to-use culture.
Stalljen Kveik Pro is fast and robust. It adapts easily to brewing without temperature control. It’s ideal for breweries that want to speed up production without compromising quality. Even in summer, it ensures clean, stable and versatile fermentation (8-38°C).
💡 And the bonus ? One 300 g bag is enough to ferment 10 HL of beer.
Thermotolerance and fermentation efficiency of K.22 Stalljen Kveik
| Features | Advantages for the brewery |
| Temperature range: 8°C – 38°C | Versatile profile, even attenuation and sensory stability, even without glycol or refrigerated cellar. |
| Rapid fermentation kinetics | Final density reached in 36 to 72 h (around 30°C), which speeds up vat rotation. |
| Bacteria-free, multi-stage aromatic synergy | Neutral from 8°C to 15°C. Fruity and spicy notes more present as temperature rises. |
| High tolerance to ethanol and osmosis | Effectively ferments strong ales, where monocultures can fail. |
Temperature benchmarks & recommended beer styles :
| Target temperature | Beer style | Justification technical |
| 8-15 °C | Lager/Steam beer Cold IPA | At this low temperature, Stalljen’s profile is very neutral. The result is a clean profile, ideal for highlighting pilsner and pale malts. |
| 20 -30°C | Malted Blonde | Moderate heat will bring out the aromas of apple, anise and clove. Ideal for thirst-quenching beers. |
| 30-38 °C | Farmhouse traditional Norwegian Wheat beers Season | With its good attenuation and pronounced ripe fruit/spices at this temperature, Stalljen will be perfect for beers where fermentation character is desired. |
Recommendations for use :
Seeding rate : 30 g/HL
Ventilation : A single injection of oxygen at 8-10 ppm is sufficient. As the culture is robust, no additional input is required.
Temperature rise : Ambient temperature can rise naturally – no impact on aroma. The strain mix remains stable, even in the event of a rapid rise.
Packaging : For crystal-clear beer, we recommend cold crashing or centrifuging, depending on your habits.
Strategic assets for the summer season :
Energy savings : Less load on the chiller means lower consumption. The result: lower operating costs, especially during periods of high demand.
Continuous production : The strain can be brewed all year round, even without an air-conditioned cellar or dedicated cooling system.
Faster time to market : Rapid fermentation facilitates seasonal launches. Perfect for festivals, summer events and tourist peaks.
K.22 Stalljen Kveik quick summary :
Stalljen is clearly the most versatile yeast in Kveik Yeastery’s pro range. We were able to try it on a traditional Norwegian Kornøl and on a Steam beer (here in the brassam version). Two very different styles. The first, very round, fruity and spicy (fermented at 37°C) and the second, fermented at 15°C, very clean and thirst-quenching.
In short, Stalljen is a robust, well-balanced multi-strain yeast, perfectly adapted to high fermentation temperatures. It transforms ambient heat into a technical asset.
By modulating temperature according to the style brewed, breweries can ensure quality, gain in speed and reduce energy consumption – especially during hot weather.
