Pyrgos-based organic estate founded 1997 by the late Haridimos Hatzidakis (1965 to 2017), a self-taught winemaker who pioneered the organic dry Santorini style.
Tasting: By appointment; structured tastings in the cellar including the Skitali (the heir) bottling continued in memory of the late founder, plus Aidani, Mavrotragano and the Hatzidaki Cuvée 17.
Signature wines: hatzidakis-santorini, hatzidakis-aidani, hatzidakis-mavrotragano, hatzidakis-skitali
Tip: The single-vineyard Cuvée 17 is the estate's most ambitious dry white; the rare monovarietal Aidani shows the lifted floral side of the PDO blend.

Five-generation Gavalas family canava in the centre of Megalochori, producing roughly 90,000 bottles a year across 11 wines. The range includes monovarietal bottlings of Katsano (white) and Voudomato (red), two heritage island grapes seldom seen as single varieties elsewhere on Santorini.
Tasting: Year-round; intimate tasting room at the family canava in central Megalochori. Tasting flights include monovarietal bottlings of the rare indigenous Katsano (white) and Voudomato (red), seldom vinified as single varieties on Santorini.
Signature wines: gavalas-santorini, gavalas-katsano, gavalas-voudomato, gavalas-vinsanto
Tip: Visit specifically for the Katsano and Voudomato; monovarietal bottlings of these heritage island grapes are uncommon at other Santorini cellar doors.
