Fermentis – Safale K-97 German ale yeast

Fermentis – Safale K-97 German Ale Yeast

German ale yeast selected for its ability to form a large firm head when fermenting.

Suitable to brew ales with low esters and can be used for Belgian type wheat beers.

Its lower attenuation profile gives beers with a good length on the palate.

Total Esters: 23 ppm at 18°P at 20°C in EBC tubes

Total Superior Alcohols: 248 ppm at 18°P at 20°C in EBC tubes

Residual Sugar: 10 g/l *corresponds to an apparent attenuation of 81%

Flocculation: High

Fermentation Temperature: 12-25  ideally 15-20C (59-68F)

Dosage Intructions: 50 to 80 g/hl

Rehydration Instructions:

Sprinkle the dry yeast in 10 times its own weight of sterile water or wort at 27C ± 3C. Gently stir for 30 minutes and pitch the resultant cream into the fermentation vessel.

Alternatively, pitch dry yeast directly in the fermentation vessel providing the temperature of 

the wort is above 20C. Progressively sprinkle the dry yeast into the wort ensuring the yeast

covers all the surface of wort available in order to avoid clumps. Leave for 30 minutes and

then mix the wort e.g. using aeration.

Storage: Store in cool (< 10C), dry conditions. If opened sachets must be sealed and stored at 4C and used within 7 days of opening.
