Safale K97 German Ale Yeast - Fermentis

Safale K97 German Ale Yeast - Fermentis

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

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.
Recommended temperature range: 59-68°F.
*See the technical data sheet below for more information on rehydration, usage and storage.

Trial. Good luck with Saflager. Dry yeasts store better, less hassle.

This might be the best dry yeast I have ever used.

Since by mail I get a dry yeast & both brews are German. Even though Helles should be lager I'm going to use an ale yeast this time.

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.
