Abstract
The present invention relates to a new yeast product that is suitable for the production of beer, and uses of this product. The product is a closed container containing 0.1 to 50 l of a frozen yeast product wherein the frozen yeast product contains at least one strain, e.g. one, two or three yeast strains, suitable for beer brewing in a total concentration of at least 109 CFU/g, with each yeast strain suitable for beer brewing being present in a concentration of at least 108 CFU/g, the frozen yeast product provides a liquid aqueous suspension with a dry matter content below 35% (w/w) upon thawing; and no cryoprotectant is added to the frozen yeast product.
Claims15
A closed container containing 0.05 to 50 L of a frozen yeast product, wherein:
- the frozen yeast product contains at least one strain effective for beer brewing in a total concentration of at least 109 CFU/g, wherein each yeast strain effective for beer brewing is present in a concentration of at least 108 CFU/g,
- upon thawing, the frozen yeast product yields a liquid aqueous suspension with a dry matter content below 35% (w/w);
- and
- the frozen yeast product does not include a cryoprotectant.
The method according to claim wherein cellular trehalose content is increased during or subsequent to the growing by inducing a stress response mechanism.
