Our wineries guide covers how to plan a tasting day; this page names specific, well-established producers worth knowing before you choose. All are real, currently operating wineries — but opening hours, tasting formats and prices change, so confirm directly before visiting.
Santo Wines
The island's largest producer, run as a cooperative and perched directly above Athinios port with one of the biggest caldera-facing terraces on Santorini. It's the most visited winery on the island by a wide margin, with the broadest tasting menu — the trade-off is that it draws considerably more coach and cruise-group traffic than the smaller estates below.
Venetsanos
Built in the 1940s above the same port as the island's first industrial-scale winery, Venetsanos offers a similar caldera-and-sunset view to Santo Wines with a noticeably calmer, less commercial atmosphere.
Estate Argyros
A family-owned estate with vines dating back over a century, now run by a fourth-generation winemaker. Known for serious, award-winning Assyrtiko and Vinsanto, and for one of the more educational tasting experiences on the island — a good choice if you want real depth on how the wine is actually made.
Domaine Sigalas
Located near Oia in the island's north, Domaine Sigalas is considered one of Santorini's more high-end producers, farming a notably wide range of grape varieties across a large estate, with wines that have picked up awards in both Greek and international competitions.
Hatzidakis
Santorini's only certified organic winery, founded in the late 1990s and built around a cave cellar. Distinctive for ageing much of its wine, including long-aged Vinsanto, underground, and for a red wine made from the rare local Mavrotragano grape alongside its Assyrtiko.
Gavalas and Canava Roussos
Two of the island's older, smaller family producers — Gavalas has been running for generations and is popular with locals precisely because it isn't built for tour buses, while Canava Roussos, dating to the 1800s, is among the oldest continuously operating wineries on Santorini. Both trade polish and views for a more traditional, low-key tasting.
