Celebrated natural winemaker Martha Stoumen, a Sebastopol native farming for healthy soils and minimal intervention, opened her first tasting room steps from the Healdsburg Plaza in late 2025. The copper-toned, open-late room pours six-taste flights of southern-Italian varietals and her playful Post Flirtation blends.
325 Center St
Martha Stoumen is one of California's most celebrated natural winemakers, a Sebastopol native who farms for healthy soils and vine longevity and lets her wines develop with a minimal hand. In fall 2025 she opened her first tasting room, steps from the Healdsburg Plaza, as part of the Overshine Collective.
The room is sensory by design: copper-toned, softly lit, open late, made to feel "sexy and relaxed." Six-taste flights move through southern-Italian varietals like Nero d'Avola and Vermentino plus the cheekily named Post Flirtation and Honeymoon blends. Nearly two dozen wines a year mean something new on every visit, with rotating bites.

Tasting Room Manager
Mike Richardson manages the Martha Stoumen tasting room, the label's first home, opened steps from the Healdsburg Plaza in fall 2025. The copper-toned room was designed to feel relaxed and stays open late, and he leads guests through six-taste flights of Martha's natural wines, from Nero d'Avola and Vermentino to the playful Post Flirtation blends.
