Fermentis Dry Yeast - Saflager S-23 (Lager)
This bottom fermenting yeast is widely used by Western European commercial breweries. This yeast develops the best of its flavors when fermented at low temperatures (48F-59F) yet it can still lager characteristics at higher temperatures. We recommend that you keep it between 48F-59F to produce the best beer possible.
This yeast can be pitched directly, but if you prefer to rehydrate, the instructions are below:
Sprinkle the yeast in a minimum of 10 times its weight of sterile water or wort (we suggest 4 oz) at 70°F to 77°F (21 to 25 °C). Do not stir. Leave to rest 15 to 30 minutes. Gently stir for 30 minutes, and pitch the resultant cream into the fermentation vessel.
