Fermentis | SafAle™ K-97 German Ale | Dry Beer Yeast

Fermentis | SafAle™ K-97 German Ale | Dry Beer Yeast

Please select from the following option(s) to see pricing and availability.

  • K-97 is ideal for delicate beers like Kolsch, Wits and Session Beers as well as heavily hopped beers
  • Tends to present floral and balanced fruity character depending on fermentation conditions
  • Fermentis active dry yeast offers reliability, ease-of-use, and consistency to home and professional beverage makers across the world

The perfect dry yeast for your German ales or Belgian-style wheat beers. K-97 is selected for its penchant to form a large, firm krausen while fermenting. A great choice for ales that you want to have a low ester character. The lower attenuation of K-97 makes for beers with a nice mouthfeel. Can ferment anywhere between 54-77°F, although the ideal range is between 59-68°F.

This yeast can be pitched directly, but if you prefer to rehydrate, the instructions are below.

Sprinkle the yeast in a minimum of 10 times its weight of sterile water or wort (we suggest 4 oz) at 70°F to 77°F (21 to 25 °C). Do not stir. Leave to rest 15 to 30 minutes. Gently stir for 30 minutes, and pitch the resultant cream into the fermentation vessel.

  • Attenuation: 80-84%
  • Sedimentation Time: Slow
  • Alcohol Tolerance: 9-11% ABV
  • Optimum Fermentation Temp: 64-78°F

*See the technical data sheet below for more information on rehydration, usage and storage.

Does this yeast produce enough Krausen to require setting your airlock as a blowoff (using the barb inside the airlock and some tubing to go into a bucket of water) instead of a traditional 3-piece airlock? Have you had any issues with Krausen clogging up a 3-piece airlock?
Sejin Kim on Apr 9, 2023
BEST ANSWER: like all yeast it depends on the OG number, the amount of yeast pitched and the temperature; nevertheless, it works well at OG under 1.06, one pack of K97, wort temp at pitching of 65 degrees and room temp at 68 degrees.

Solid and Dependable
I used one packet to ferment 5 gallons of Alt bier. Rather than rehydrate as I usually do for lagers, I sprinkled the packet directly onto of the top of wort at 58F. It took about 24 hours for fermentation to ramp up, and it was nearly complete five days later. I used dry yeast nutrient (also sprinkled on top of wort), but did not oxygenate. Very happy with the product - I will likely use K97 with my next Kölsch.

Fast Start to Fermentation
The fermentation kicked off almost as fast as Kveik. Good consistent results with this yeast. Always nice to have a dry yeast on hand.

Powdery, but give it time!
Ferments well down to 53-55F. Made some very clean Kolsch style ales with it. I found fining with gelatin helps speed up clearing otherwise I've lagered for 2, sometimes 3 weeks, to get a brilliantly clear beer.

Produces a structured, well balanced beer in my experience. Giver er a shot!

Worked fine but was really slow to flocculate. I brewed an award winning Alt Bier with it. Lots of subtle flavors. Give it time to lager.

Love this strain
This kolsh dry yeast never disappoints. Every time I've used it - it is always very floculant with high attenuation - always ferments fast, rapidly picking up after pitching and then finishes within a week - usually much faster than SA-05. The beer is clear and consistent - if you like the flavor, you can't beat this yeast.

Excellent yeast for a German kolsch ale
I have used this yeast twice to make a kolsh ale. It is rapid fermenting and produces a clear ale which has a great flavor.
