BBOSL – OSLO™

Availability: Limited

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.

Product Category: Dusty Bottoms Collection™

The Dusty Bottoms Collection™ is our ode to unique and hard to find cultures sourced from commercial fermentations. As much as we love local yeast, there are just some flavors and aromas that can’t be reproduced by plucking yeast out of thin air.

Many of these cultures have been used for generations to make some of the most consistently wonderful beverages in the world. Whether it’s brewer’s yeast, Brettanomyces, or Lactobacillus…these aren’t Local Yeast by our definition, but certainly were local at one time.

    Awesome stuff! I made a Czech Pilsner that fermented super clean in 3 days (@85 degrees). I absolutely love this stuff and will make this my house yeast strain. It’s a must try!

  2. Squid (verified owner)

    Really is awesome. I brewed an American Light Lager. Started fermentation quickly after pitching. finished clean in 3 days (@ 80 degrees – 10.33 to 10.03). I don’t normally harvest yeast, but definitely doing it with this!

  3. Tyler Cannon (verified owner)

    Brewed a czech pilsner, delicious. I saved half the slurry and made a shiner bock clone, seems like it will also be delicious. Dried the other half to see if it performs like other kveiks, making an Azacca IPA (or IPL?) currently and it’s drugging away with the dried stuff.

    A homebrewer’s best friend; super clean, super fast, and easy to harvest for reuse! Oh, and most importantly, makes delicious beers

    This may easily become a house yeast strain for me (if Bootleg keeps it available on the homebrew side); it’s easily one of the best yeast strains I’ve used. I made an international pale lager on 5/25, and on 5/28 I took a gravity reading and it had fermented from 1.045 to 1.010 in a little over three days. The clean profile blew me away, especially since I was fermenting at 78 F. I intend on pitching another batch of beer onto this yeast cake (perhaps another lager or even more adventurous a dopplebock). I’m really happy with the performance of this yeast! Well done, Bootleg!

    Made American Lager with the yeast cake. This time had it at 90 degrees and within 3 days result in 85% attenuation. Raised it to 95 degrees and it awoke again briefly to squeezed out a couple more points. Thinking about a German Pils next.

    Made a bohemian pilsner with O.G. at 1.060 and fermented in my garage in the 80F for 2 days. Unfortunately I had to bring it in the house because it was supposed get in the 100s here in Florida for the next few days. After 2 days in the 70s it was down to 1.010. The beer is delicious with no off flavors. I pulled a couple 100ml from the slurry for a pale ale (OG 1.050) and this time left it in the garage for 3 days in the mid to hi 90F. Final gravity was stable at 1.010. I am loving this yeast strain!!

    Amazing! Really impressed with this strain. Fermented an IPL in 4 days at 95F. Super clean, great flavor. Never been interested in harvesting yeast until now.
