RAYMOND EDER, María Laura  and  ROSA, Alberto Luis. Yeast diversity in Vitis non-vinifera ecosystems. Rev. argent. microbiol. [online]. 2019, vol.51, n.3, pp.278-283. ISSN 0325-7541.  http://dx.doi.org/10.1016/j.ram.2018.09.004.

The surface of grapes lodges a complex community of yeast species responsible for spontaneous alcoholic fermentation. The study of indigenous Saccharomyces and "non-Saccharomyces" yeasts during grape must fermentation constitutes a major research area in microbial enology. Although there are detailed studies on the microbiota of Vitis vinifera grapes, little is known about the diversity of yeast communities present in non-vinifera Vitis ecosystems (i.e., grapes and spontaneously fermenting grape musts). Potentially scientific and/or enological valuable yeast strains from these non-vinifera Vitis ecosystems might never be isolated from V. vinifera L. In this updated review, we summarize relevant aspects of the microbial studies conducted on V. non-vinifera grapes and spontaneously fermenting grape musts.
