Fungi found on Cabernet Sauvignon grapes in China’s Penglai region—including Colletotrichum, Alternaria, Saccharomyces, and Hanseniaspora—shaped each wine’s unique flavor and aroma during spontaneous fermentation. Despite being grown within just 18 miles of one another, vineyards had distinct microbial profiles that influenced 64 different volatile compounds. This deep microbial imprint reveals just how much fungi contribute to regional wine character.
