Hatzidakis: the Organic Cave Winery of Pyrgos

The cult estate that doesn’t do drop-ins

Ask Greek sommeliers to name the Santorini producer they’d defend in a bar argument and Hatzidakis comes up first with striking frequency. Haridimos Hatzidakis founded the estate in 1997 on convictions that were lonely then and are fashionable now: certified-organic farming on an island where wind and drought punish it, native yeasts, minimal handling, and vinification in a cave dug beneath the vineyard itself. After his death in 2017, his daughter Stella Hatzidaki took direction, and the wines have — by broad critical consent — never been better.

The estate’s summits are single-parcel old-vine Assyrtikos: de Louros, from centuries-old vines in a sheltered ravine, and de Mylos, by the old mill — wines of nerve and density that make the grape’s world-class case without raising their voice. The VinsantoThe island’s amber crown: sun-dried Assyrtiko, Athiri, and Aidani, barrel-aged for years into a sweet wine of apricot, caramel, and coffee held fresh by improbable acidity., when a vintage releases, disappears fast.

Hatzidakis is the least casual visit on Santorini, by design: appointment only, no walk-ins, Tuesday through Saturday, 9:30 to 15:30 — no Sunday, no Monday, no evenings, no sunset terrace (the cellar is a cave; the view is barrels). Three official tastings run in 2026: €40 for four wines, €80 for six plus a vineyard walk among the kouloura, and the collector’s €160 twelve-wine deep-dive including old vintages, which needs at least a day’s notice. Summer slots are genuinely scarce — the tasting room is small and the team would rather pour well for few than badly for many.

Those constraints are exactly why no shared tour on the island can include Hatzidakis — the hours preclude sunset circuits and the appointment policy precludes flexible group logistics. It anchors the morning of our Private Cellar tour instead, where the reservation, the timing, and (if you want it) the twelve-wine arrangement are handled before you land. Guests who’ve tasted everywhere tell us this stop is the reason to go private; we’ve stopped arguing.

How do you visit Hatzidakis independently?

Book direct and early, arrive on time (the schedule is real), and budget 60–90 minutes. Pyrgos Kallistis sits mid-island, ten minutes from Fira — combine with lunch in Pyrgos village, whose castle quarter is the island’s most underrated wander, or pair the morning here with an afternoon at Estate Argyros fifteen minutes east for the island’s two deepest cellars in one day. No car? A taxi works; better, the private day makes the appointments and the driving someone else’s job — ours.

What should I know before visiting Hatzidakis Winery?

Hatzidakis is Santorini’s benchmark organic estate, founded in 1997 by Haridimos Hatzidakis and directed by his daughter Stella since 2017, vinifying in a cave dug beneath its own vineyard in Pyrgos Kallistis, ten minutes from Fira. The rules are firm: appointment only, no walk-ins, Tuesday through Saturday, 9:30–15:30, year-round — no Sunday, no Monday, no evenings. Three official tastings run in 2026: €40 for four wines, €80 for six plus a vineyard walk, and €160 for the twelve-wine deep-dive with old vintages, which needs at least a day’s notice. Summer slots are genuinely scarce, so book direct and early, arrive on time, and budget 60–90 minutes. The estate is known for certified-organic farming, native yeasts, and the single-parcel old-vine crus de Louros and de Mylos. No shared tour can include it; it anchors the morning of our Private Cellar tour, reservation handled.
