Bootleg Biology OSLO Kveik

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.

OSLO can comfortably produce beautifully clean, lager-like beers at temperatures as high as 98F (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.

Brewing Info*:

• Type: Bottom fermenter. Saccharomyces bayanus / pastorianus / uvarum monoculture
• Pitching Rate: Directly pitchable into 5 gallons of 1.050 or lower wort
• Estimated Attenuation: 76-86%; attenuation will increase with higher fermentation temps or with successive repitches
• Estimated Final pH: 4.3-4.6
• Flavor/Aroma Profile: Clean, lager-like flavor profile, with no expected off flavors or phenols at high temperatures
• Flocculation: Medium
• Recommended Fermentation Temperature: 85F-98F (29C-37C); colder temperatures may result in higher final gravities or early flocculation/stalling. Pitch and Ferment at 95F (35C) for quickest fermentation time.

Please note: It is highly recommended that a cold pack be purchased when ordering liquid yeast. High Gravity cannot guarantee the viability of liquid yeast if it fails to work unless it was purchased with a cold pack. You can add it to the order by checking the cold pack box near the bottom of the page before adding the yeast to the cart.
