Scientists prove regional variations in yeast (NZ)

Scientists in New Zealand have proved for the first time that wine yeasts vary from region to region. The research, conducted by Velimir Gayevskiy and Dr Matthew Goddard of the School of Biological Sciences at the University of Auckland, detected distinct differences between indigenous yeast strains in different regions. The study, which has been published in the Journal of the International Society for Microbial Ecology, investigated yeasts present on Chardonnay and Syrah grapes, and their spontaneous ferments, in vineyards in three distinct wine regions in New Zealand, reports Decanter.
