strain family
Kveik
Norwegian farmhouse yeast cultures that ferment extremely fast at very high temperatures without producing fusel harshness.
Kveik is a family of maintained farmhouse cultures from western Norway, traditionally dried on wooden rings and reused for generations. They ferment at 30–40 °C — temperatures that would produce hot, solvent-like fusel alcohols in any conventional strain — and instead give clean beer with heavy orange and tropical esters.
That tolerance is genuinely unusual and is the reason they moved rapidly from obscurity to worldwide commercial use after the 2010s.
