摘要： The present invention provides a new wine yeast product in a frozen form. The product is produced in a fermenter, concentrated, cryoprotectants are added. This mixture is then frozen at −50° C. What makes this product unique is that besides the fact that it is frozen, it can be directly added to grape juice as no rehydration is required because the yeast was not dehydrated in the production process.

摘要： The present invention relates to modified industrial yeast strains that show reduced hydrogen sulfide production. In one embodiment the invention provides an industrial yeast strain comprising a modification in a MET5 gene and/or a MET10 gene which results in reduced hydrogen sulfide production when compared to the corresponding industrial yeast strain without the modification. The present invention also relates to methods of manufacturing these modified industrial yeast strains and their use in the production of fermented products.

摘要： It has unexpectedly been found that Pichia spp. strains have advantageous properties useful in the beer fermentation process. In particular, Pichia spp. yeast strains can be combined with normal beer yeast strains and different hop varieties in a fermentation process to produce synergistic effects—namely, the increased production of esters in the fermentation product. More specifically, the yeast can be used to produce increased levels of isoamyl acetate, isobutyl acetate, ethyl propionate, ethyl valerate, ethyl butyrate, ethyl decanoate and ethyl octanoate in beer. In addition, the Pichia spp. strain interacts differently with different hop varieties, so the flavor profile of beer can be tuned by using different combinations of Pichia spp. strains and hops. The present invention relates to a method of brewing beer using a Pichia spp. yeast strain and at least one hop variety, a beer obtainable by such a method and use of a Pichia spp. yeast strain according to the present invention.
