SafLager S-189 (Swiss) [11.5g] Yeast

SKU: 3516668180000

Fermentis SafLager™ S-189 originating from the Hürlimann brewery in Switzerland. SafLager™ S-189 lager strain’s attenuation profile allows to brew fairly neutral flavor beers with a high drink-ability.


Available in 11.5g sachets


Fermentation temperature: Ideally 12-15°C (53.6-59°F)



  • 30 ppm ppm at 18°P at 12°C during the first 48 hours of fermentation then 14°C in EBC tubes



  • 170 ppm at 18°P at 12°C during the first 48 hours of fermentation then 14°C in EBC tubes



  • 4 g/l*

*2g maltotriose/L corresponding to an apparent attenuation of 84%



  • +



  • Fast


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.
