DESIGNED FOR BOTTLE AND CASK CONDITIONING
SafAle™ F-2 brewing yeast has been selected specifically for secondary fermentation in bottle and in cask. This yeast assimilates very little amount of maltotriose but assimilates basic sugars (glucose, fructose, saccharose, maltose). It is characterized by a neutral aroma profile respecting the base beer character and settles very homogeneously at the end of fermentation.
From 2 to 35g/hl at 15-25°C (59-77°F).
SafAle™ F-2 should not be rehydrated directly in the beer.
Sprinkle the yeast in minimum 10 times its weight of sterile water at a temperature of 25 to 29°C (77°F to 84°F).
Leave to rest 15 to 30 minutes. Gently stir.
Add 5 to 10 grams of sugar per liter of beer (to obtain a saturation of 2.5 to 5.0 g/l of CO2). Pitch the sweetend beer, that should be at fermentation temperature (20-25°C) with the rehydrated yeast.
Carbonation will be achieved in 1 to 2 weeks at 20-25°C*
At the end of refermentation, the beer can be cooled down and will gain in roundness after 2 to 3 weeks.
* carbonation at 15°C can take over 2 weeks
