SafBrew F-2 - 500G

Fermentis SafBrew F-2 500g Yeast


Safbrew F-2 has been selected specifically for secondary fermentation in bottle and in cask. This yeast assimilates very little maltotriose but assimilates basic sugars (glucose, fructose, saccharose, maltose) and is characterized by a neutral aroma profile respecting the base beer character.

Safbrew F-2 resists to high alcohol levels (>10% v/v) and allows brewers to obtain all the properties of refermentation :

  • Beer preservation thanks to oxygene trapping
  • Contribution in roundness and maturation aromas
  • Carbonation
  • Sticks well at the bottom of the bottles/casks and forms a nice haze when it is resuspended

    Safbrew 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 27°C ± 3°C (80°F ± 6°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.
