Fermentis SafAle K-97 is a German ale yeast selected for its ability to form a large firm head when fermenting. Suitable to brew ales with low esters and can be used for Belgian type wheat beers. Its lower attenuation profile makes for beers with a good mouth-feel. This ale yeast works at a wide temperature range between 53.6-77°F (12-25°C) but ideally between 59-68°F (15-20°C). Highly flocculant.
