How Native Yeast Fermentation Shapes Chardonnay and Pinot Noir

Wild yeast, wild character

WWMD – What would Margaret drink? Margaret Pearman, a certified sommelier with the Court of Master Sommeliers, curates the acclaimed wine list at Charlie’s L’Etoile Verte. For April, she highlights two Littorai wines that capture the ever-changing character created through native yeast fermentation.

In the rolling hills of Anderson Valley and the Sonoma Coast, where Littorai Winery sources its grapes, winemaker Tom Lemon is redefining what it means to craft authentic wine. At the heart of his philosophy is a method as old as winemaking itself: wild, or native, yeast fermentation.

Unlike commercial yeasts bred for predictability and uniformity, wild yeasts are the naturally occurring microorganisms found on grape skins and in the winery’s environment. While many modern winemakers rely on additives and cultured yeasts to ensure consistency, Lemon takes the opposite approach, embracing native yeasts as a way to highlight the individuality of each vineyard and vintage.

During harvest, Lemon brings in hand-picked chardonnay and pinot noir grapes, taking care to preserve their natural bloom. In the cellar he resists adding cultured yeasts, allowing native populations to begin fermentation on their own timetable. The process demands patience and careful monitoring, since wild fermentations can be unpredictable. For Lemon, that unpredictability is precisely where the magic lies.

The result is wine that feels alive with place. Littorai’s chardonnay reveals layers of minerality and vibrant texture, while the pinot noir develops nuanced aromas and flavors often muted by commercial yeast strains.

“Wild yeast fermentation brings out the vineyard’s true voice and adds a subtle, ever-changing character to each bottle,” Lemon says.

For Lemon and Littorai, letting nature take the lead is not just a technique. It is a philosophy that ensures every vintage tells its own story.
