SafAleTM F-2 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.
Yeast (Saccharomyces cerevisiae), Emulsifier E491 SafAleTM F-2 resists to high alcohol levels (>10% v/v) and allows brewers to obtain all the properties of refermentation:
– Beer preservation thanks to oxygen 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
Given the impact of yeast of the quality of the final beer it is recommended to respect the recommended fermentation instructions. We strongly advise users to make fermentation trials before any commercial usage of our products.
