Description
Michela Dell'Alma and a large team track, in a 2026 study, the microbes and chemistry of spontaneous fermentation in Picolit, a wine grape from northeast Italy. Picolit grapes often form uneven berries and carry high sugar. Unlike guided fermentations, the spontaneous kind relies on microbes from the vineyard itself. Grapes came from an organic winery in the Savorgnano area of Friuli. Five fermentation stages were sampled.
Gene sequencing and chemical profiling followed the handover between microbe sets. Starting juice held a mix led by non-Saccharomyces yeasts, oxygen-using bacteria, and the gray mold fungus. That fungus oddly persisted and grew, hinting at a tight tie to the grape's traits. Early stages featured varied yeasts linked to acid balance and aroma building. From mid-fermentation, several Saccharomyces species took over as bacterial variety shrank. The authors describe a local path shaped by grape traits, place, and native microbes.
