A special type of wine yeast suitable for fermenting wine at low temperatures. The normal working temperature of this yeast is 13-17 C, but fermentation is possible at 10 C (some winemakers claim to have seen this yeast working at 8 C).
Suitable for making all wines, but especially white, rosé, sparkling, cider. Characterized by a strong "killer" effect, is a strain of Saccharomyces cerevisiae var. bayanus.
Dosage 20-40 g/100 l of must (the lower the fermentation temperature, the higher the recommended dose).
