Source: Isolated yeast discovered in bottle dregs from our friends Eik & Tid (Oslo, Norway)

OSLO is a modern take on traditional Norwegian farmhouse brewing cultures, producing beautifully clean, lager-like beers at temperatures as high as 37C without noticeable off flavors. At the high end of fermentation temperature, beers can finish attenuating in as little as three days! This culture’s versatility and neutral flavor profile allows you to effortlessly produce most beer styles.

Bootleg is the first yeast lab to release this unique Kveik-family culture sourced from a raw beer made by our good friends at Eik & Tid in Oslo, Norway.
