Description
  • L28 is an excellent choice for your Czech lager fermentations with a nice balance between hops and malt

L28 Urkel is a traditional Czechoslovakian lager strain that provides exceptional balance between hops and malt. Slightly sulphery during fermentation, but will clean up nicely during lagering. Ferment toward the higher end of the range for a beer with minimal sulfur notes and a light ester profile.

Flocculation: Medium
Alcohol Tolerance: 10% ABV
Optimum Fermentation Temp: 52-58°F
Cell Count: 200 Billion
Similar Strains: WLP800, WY2001

Please Note: For best results we Always recommend ordering an Ice Pack with your liquid yeast. Ice Packs can be found below in the "You might Also Need" section.

Please Note: When choosing an ice pack option beware that the liquid yeast will not arrive cold even when shipped together. Ice packs and insulated mailing options are designed to keep the yeast colder for longer during shipment, but they will not ensure that your yeast arrives cold. We will not replace liquid yeast that arrives warm. During warmer months we strongly recommend you choose dry yeast.

Good yeast, used it before.
Jamie W on Dec 4, 2020
This yeast ferments clean and fast at ale temps (66F). I've done several batches of German lagers that all were absolutely delicious with no off flavors this way.

Oktoberfest
Took off like a rocket in my Oktoberfest. Used instead of Harvest which is my typical go to. Attenuated down to 1.010. Fermented warm. No sulfur to speak of after a ramp up. Clean. Crisp. Delicious.

First lager
I enjoyed this yeast for many reasons.
Fermented my beer in roughly 2 weeks.
Did a good job clearing up after fermentation
The yeast flavor is there! but it doesn't outshine your malt or hop characters

Nice lager yeast
I made a starter because I made a 10 gallon batch, but I'm not even sure I needed to do it. I hit FG in under 4 days at 54 degrees.

It throws a good amount of sulfur during fermentation, but it's going away pretty fast now that it's lagering. Beer tastes great! I will buy again.

Just a really clean and healthy yeast otherwise.

Organic Yeast, Twice the Cell Count, and Awesome Customer Support
This is an amazing producer of yeast. I have sent an e-mail on a Sunday and received a call back in less than an hour. I have used several of their products. This yeast worked very well and resulted in a very tasty lager on my first lager attempt.
