S. diastaticus: A yeast loved – and feared
Over-attenuating yeast | At the turn of the century, hardly anyone in Germany was familiar with this yeast. Nowadays, Saccharomyces diastaticus has virtually become a household name, especially among craft brewers. Some use it to brew novel beers in the style of those from Belgium. Others, however, fear this yeast and despise it as a beer spoiler, conducting extensive analyses to detect the merest traces of its presence in an effort to eradicate it in their breweries.
