Today in 2014, US Patent 20140234480 A1 was issued, an invention of Sofie Sarens and Jan Hendrik Swiegers, assigned to Chr. Hansen A/S, for their “Enhancement of Beer Flavor by a Combination of Pichia Yeast And Different Hop Varieties.” Here’s the Abstract:

In the beer fermentation process, Pichia spp. yeast strains can be combined with normal beer yeast strains and with different hop varieties to produce synergistic effects, including the increased production in the fermentation product of esters, e.g., increased levels of isoamyl acetate, isobutyl acetate, ethyl propionate, ethyl valerate, ethyl butyrate, ethyl decanoate, and ethyl octanoate. Additionally, the Pichia spp. strain interacts differently with different hop varieties, such that the flavor profile of beer can be tuned by employing different combinations of Pichia spp. strains and hops.
