This product is a blend of active dry yeast and enzymes. It is recommended for the production of particularly high-attenuating beers and for very high gravity fermentations, such as Barley Wines. The yeast strain in this blend is able to reach 18% alc. (v/v), depending on the process and the substrate, with a very good resistance to osmotic pressure and high fermentation temperatures.

Optimum fermentation temperature 25-35°C  (77-95°F).
