Kveik yeast is a type of yeast that originates from Norway and has been used in traditional farmhouse brewing for centuries. It is known for its ability to ferment at high temperatures, producing unique and flavorful beers.
Kveik yeast is different from other types of yeast in several ways.
First, kveik yeast strains are able to ferment at high temperatures, often between 80-100°F, while other yeast strains may struggle at these temperatures. This ability allows brewers to produce beer quickly, as the fermentation process is accelerated at higher temperatures.
Kveik yeast is known for producing fruity and spicy flavors and aromas, which can enhance the character of the beer.
Another difference from standard brewing yeasts is the genetic diversity of kveik yeast strains.
While most commercial yeast strains are cultured from a single strain, kveik yeast is often a mixture of multiple strains that have been passed down from generation to generation. The diverse genetic makeup of this yeast can lead to a greater range of flavors and aromas in the beer.
Finally, kveik yeast is known for its high flocculation, which means that it forms clumps that settle out of the beer more readily than other yeast strains. This can simplify the clarification process, as the yeast will settle out more quickly, making it easier to achieve a clear beer.
Some of the styles of beer that kveik yeast is commonly used in include:
- Saisons: The fruity and spicy notes produced by kveik yeast can complement the spicy and earthy flavors of a saison, producing a complex and refreshing beer.
- IPAs: Kveik yeast can add an extra layer of fruity flavors to an IPA, complementing the hoppy bitterness and creating a well-balanced beer.
- Fruit Beers: The fruity flavors produced by kveik yeast can enhance the character of a fruit beer, making it a popular choice for brewing fruit-infused beers.
- Sours: Kveik yeast can produce a unique and complex flavor profile when used in sour beers, adding a unique and refreshing character to the beer.
- Pilsners: Kveik yeast can produce a crisp and clean beer when used in pilsners, making it a popular choice for brewing lagers and pilsners.
