Vassaltis produces wines from Santorini, the volcanic Cycladic island where Assyrtiko thrives in mineral-rich soils and intense Mediterranean sun. The winery's Gramina Cuvee des Vignerons, a pure Assyrtiko expression, demonstrates the variety's signature tension between bright acidity and saline minerality. Assyrtiko Barrel Aged shows how oak aging deepens the grape's structure and complexity. The winery also crafts Vinsanto, a traditional sweet wine blending Athiri, Aidani, and Assyrtiko—a style that has defined Santorini for centuries. These wines have been assessed by Wine Enthusiast, Wine Advocate, Decanter, and Wine Spectator. Santorini's volcanic terroir and extreme growing conditions produce whites of distinctive character: lean, focused, and marked by the island's unique geology.
