Eastern Viticulture & Enology Forum: The Wine Microbiome–Implications for the wine industry

March 18, 2025

Molly Kelly

Dr. Molly Kelly, Enology Extension Educator at the Pennsylvania State University, outlines her ongoing research investigating changes in microbial populations, particularly non-Saccharomyces yeasts, during native fermentations. Could this be used to define your microbial terroir? The presentation is followed by an exciting discussion with two producers of "naturally" fermented wines, exploring their philosophies, best practices, and challenges.
