FERMO BREW CITRUS

FERMO Brew Citrus is an aromatic yeast strain obtained by hybridization. Thanks to its medium nutrient requirement, this yeast strain produces a pleasant full-bodied profile even in the early phase of fermentation compared to normal brewing yeast, enabling brewers to produce alcohol-free or low-alcohol beers with elegant aromatic berry notes using the fermentation interruption method (<0.5 % vol.).

Remarks

FERMO BREW CITRUS enhances aroma-active thiols in the early stage of fermentation. Phenolic compounds (POF+) are produced in the later stages of fermentation. Yeast nutrients from the FERMOPLUS® range will further enhance the aroma profile. For low alcohol beers a pH correction is recommended. Despite the high alcohol tolerance FERMO BREW CITRUS produces low volumes of alcohol during fermentation making it particularly suited for brewing low and non alcohol beers.

Use

It is generally recommended that active dry yeast is pitched directly into the wort without prior rehydration. If direct pitching is not feasible the yeast can be hydrated and pitched in liquid form. To rehydrate dissolve the dry yeast in sterile water or in wort at 11-16°C / 52-61°F at a ratio of 1:10. Stir gently and leave for approximately 20 minutes. Gently stir again and add to the cooled wort in the fermenter. To avoid yeast stress, ensure temperature fluctuations are minimal.
