Saccharomyces uvarum

Saccharomyces uvarum is a species of yeast that is commonly found in fermented beverages, particularly those fermented at colder temperatures.[1] It was originally described by Martinus Willem Beijerinck in 1898, but was long considered identical to S. bayanus.[1][2] In 2000 and 2005, genetic investigations of various Saccharomyces species indicated that S. uvarum is genetically distinct from S. bayanus and should be considered a unique species.[1][2]
