Yeast diversity in Vitis non-vinifera ecosystems.

Area of Science:

• Microbial enology
• Oenology
• Grape microbiology

Background:

• Grape surfaces host diverse yeasts crucial for spontaneous alcoholic fermentation.
• Indigenous Saccharomyces and non-Saccharomyces yeasts are key in grape must fermentation.
• Research extensively covers Vitis vinifera L. grape microbiota, but less is known about non-vinifera Vitis ecosystems.

Purpose of the Study:

• To review microbial studies on non-vinifera Vitis grapes and spontaneously fermenting grape musts.
• To highlight the yeast diversity in understudied Vitis ecosystems.
• To identify potentially valuable yeast strains for enological applications from these unique sources.

Main Methods:

• Literature review of microbial studies on Vitis non-vinifera grapes.
• Analysis of research on spontaneously fermenting grape musts from non-vinifera Vitis.
• Synthesis of findings on yeast community diversity and enological potential.

Main Results:

• Significant gaps exist in knowledge regarding yeast communities in non-vinifera Vitis ecosystems.
• Non-vinifera grapes and musts may harbor unique yeast strains with enological value.
• Current research predominantly focuses on Vitis vinifera, overlooking other Vitis species.

Conclusions:

• Further research into non-vinifera Vitis yeast diversity is essential for enological advancement.
• Exploring these understudied ecosystems could uncover novel yeast strains for fermentation.
• A broader understanding of grape yeast microbiota can lead to improved winemaking practices.
