Hatzidakis produces Assyrtiko from Santorini, the volcanic Cycladic island where this white grape reaches its finest expression. The winery's portfolio centers on single-vineyard and reserve bottlings that showcase the mineral intensity and saline tension characteristic of the region's pumice-rich soils. Assyrtiko de Mylos Vieilles Vignes, drawn from old vines, and Santorini Assyrtiko Cuvée No. 15 represent the upper tier of the lineup, with Assyrtiko Pyrgos completing a focused range. Wine Spectator, Wine Advocate, Decanter, and Wine Enthusiast have all assessed these releases. The wines embody Santorini's austere, high-altitude terroir—lean, structured, and built for aging rather than immediate consumption.
