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%
Fermentation Temperature: 12-25 ideally 15-20C (59-68F)
Dosage Intructions: 50 to 80 g/hl
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.
