Fermentis by LeSaffre SafLager™ S-189 Bevie

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:

1. Sprinkle the yeast in minimum 10 times its weight of sterile water or wort at 21 to 25 °C (70°F to 77°F).
2. Leave to rest 15 to 30 minutes.
3. Gently stir for 30 minutes, and pitch the resultant cream into the fermentation vessel.

Alternatively,

1. Pitch the yeast directly in the fermentation vessel providing the temperature of the wort is above 20°C (68°F).
2. Progressively sprinkle the dry yeast into the wort ensuring the yeast covers all the surface of wort available in order to avoid clumps.
3. Leave for 30 minutes, then mix the wort using aeration or by wort addition.

Ingredients:

Yeast (Saccharomyces cerevisiae), emulsifier E491
