Gavalas produces wines from Santorini, the volcanic Cycladic island where Assyrtiko thrives in demanding conditions. The winery's Santorini Natural Ferment, made from Assyrtiko, demonstrates the grape's mineral precision and salinity on this terroir. Katsano, a blend of indigenous varieties, and Nykteri, another Assyrtiko expression, round out the portfolio. Decanter, Wine Spectator, Wine Advocate, and Wine Enthusiast have all assessed the winery's output. Santorini's pumice-rich soils and maritime climate shape wines of distinctive character—lean, structured, and marked by the island's volcanic signature.
