Frequently Asked Questions

What is Kveik yeast?

Kveik is an old Norwegian word that simply means “yeast.” However, in today’s context, it refers to a farmhouse yeast that is usually from Norway, but there are also other versions of Kveik from Lithuania, Latvia, and further afield.

What are the characteristics of Kveik yeast?

Kveik yeast is known for its fast fermentation time, usually between one to three days, without resulting in harsh off flavors. It can support beer styles of various alcohol strengths, usually up to 15%, and still offers the same superfast conditioning times. It is suitable for a wide and varied amount of different beer styles.

How does the composition of Kveik yeast change over time?

Given time, the composition of Kveik yeast can change and mutate. This is because Kveik is multi-strain. The more strains in a Kveik, the more noticeable the shifts will be from the original composition of the yeast. This means that even if two brewers have the same type of Kveik yeast, they could be very different due to the changes and mutations over time.

What is the recommended pitching rate for Kveik yeast?

For farm multi-strain Kveik, the general consensus is one level teaspoon of Kveik for 25 to 30 liters or 6.6 to 8 US gallons, and half a teaspoon of Kveik for 15 liters or 4 US gallons. Kveik thrives from this level of pitching and will not be as happy or healthy if you add any more.

How can Kveik yeast be recultured?

Kveik yeast can be recultured by top cropping yeast, which is the process of collecting yeast from the top of the fermentation vessel during fermentation. Once the yeast is obtained, it is popular to dry Kveik on sanitary greaseproof paper. Once dried, it will crumble down like the dry yeast you’re used to seeing.
