Fermentis/Safale F-2 (SPC) 20g.

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 caracterized 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

Fermentation Temperature: 15-25°C (59-77°F)

Dosage Instructions: 2 to 7 g/hl

Instructions of Use Rehydration:

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.

USAGE:

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
