Practical brewing experience with Saccharomyces pastorianus TUM 35
Resurrected yeast | According to Hutzler et al., in 1952 and 1953, environmental conditions and variable barley characteristics led to unsustainable brewing practices with a formerly popular Frohberg-type Saccharomyces pastorianus yeast [1]. Now identified as TUM 35, the once-extinct yeast was resurrected and made commercially available in 2019. In November of 2019, Schilling Beer Company of Littleton New Hampshire, USA, imported TUM 35 from Forschungszentrum Weihenstephan with a keen interest in the history of the yeast.
