Dry yeast Lallemand BRY-97 (500 gr)

Used by many breweries to produce different types of ale, BRY-97 Lallemand dry yeast is recommended for the production of American-style top-fermented beers. Lallemand BRY-97 dry yeast is prepared in ISO 9002 certified facilities, without the use of colorants, preservatives or other non-natural substances, and undergoes propagation and drying processes designed to ensure the highest quality. American West Coast BRY-97 Lallemand beer yeast has a neutral esterified aroma, a fermentation temperature of 15-22°C, high flocculation, medium-high attenuation and an alcohol tolerance of 13%. BRY-97 Lallemand dry ale yeast is rehydrated in 100 ml of liquid at 30°-35°C and inoculated into the wort at 20°-25°C. Fermentation above 17° can be completed in 4 days. The rate and time of fermentation and the degree of attenuation can change depending on the inoculum density, yeast handling, temperature and nutritional quality of the must. The use of isinglass and clarifying agents further aids fermentation. Polsinelli Enologia recommends using the product at the traditional temperatures for Ale beers and storing at a temperature between 5°-10°C.
