Fermentis by Lesaffre SafLager™ S-189 originated from the Hürlimann brewery in Switzerland. SafLager™ S-189 yeast strain’s profile allows to brew fairly neutral flavour beers with a high drinkability. Depending on the conditions, it tends to present noticeable herbal and floral notes to lager beers. Fermentis by Lesaffre SafLager™ S-189 is a great yeast for elegant lagers with floral notes.

Pitching rate instructions:
80 to 120 g/hl (100L) (16g- 24g per 20L batch) for fermentation at 12°C – 15°C (53.6-59°F). We recommend 2 x 11.5g sachets per 19L / 5 gallon brew length to get a healthy fermentation. Increase pitching for fermentation lower than 12°C (53°F), up to 200 to 300 g/hl at 9°C (48°F)
Rehydration instructions:
- Sprinkle the yeast in minimum 10 times its weight of sterile water or wort at 21 to 25 °C (70°F to 77°F).
- Leave to rest 15 to 30 minutes.
- Gently stir for 30 minutes, and pitch the resultant cream into the fermentation vessel.
Alternatively,
- Pitch the yeast directly in the fermentation vessel providing the temperature of the wort is above 20°C (68°F).
- 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, then mix the wort using aeration or by wort addition.
