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.

PDO Santorini / PDO VinsantoAssyrtiko, Aidani, Athiri, MavrotraganoFounded 1989Sterner Stenhus Greece (acquired 2022); Antetokounmpo family minority stake since 2023Megalochori
Boutari, the Macedonia-founded Greek wine house (1879), opened its Santorini facility in 1989 at Megalochori. The Santorini cellar contributed to the international launch of Assyrtiko through the 1990s; the Nykteri bottling is a long-running reference for the night-harvest style.
Tasting: Daily tasting flights at the Megalochori winery year-round; multi-wine flights pairing Boutari Santorini, Selladia and Nykteri with Greek cheeses and meze plates.
Signature wines: boutari-kallisti, boutari-nykteri, boutari-vinsanto
Tip: Boutari Nykteri is widely distributed in export markets and ages well at 5 to 8 years from vintage; the standard Boutari Santorini is the budget-friendly entry into the PDO.

Cliff-cut winery on the caldera above Athinios port, founded 1947 by the Venetsanos family. The gravity-flow design uses the cliff face to move must downhill through pressing and fermentation; restored and reopened to visitors as a working cellar plus tasting terrace.

Signature wines: venetsanos-assyrtiko, venetsanos-nykteri, venetsanos-vinsanto

PDO Santorini / PDO Vinsanto / PGI CycladesAssyrtiko, Aidani, Mandilaria, Mavrotragano, Voudomato, KatsanoFounded 1900Gavalas family (George Gavalas, fourth generation; Vagelis Gavalas, fifth generation)Winemaker George GavalasMegalochori
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.

Signature wines: antoniou-santorini, antoniou-nykteri, antoniou-vinsanto
Tip: The rock-cut Vinsanto barrel chamber is an atmospheric tasting space; pair the visit with a stroll through central Megalochori afterwards.

Signature wines: art-space-santorini-assyrtiko, art-space-mavrotragano
Tip: Lesser-known than the Argyros family's larger Estate Argyros; a quieter alternative for visitors who want to combine wine with art in a working historic cellar.

Signature wines: volcan-wines-assyrtiko, volcan-wines-nykteri, volcan-wines-vinsanto
Tip: The cave Wine Museum is the most child-friendly wine attraction on Santorini and one of the few rainy-day options on the island; the tasting flight afterwards is solid value.

Signature wines: volcanic-slopes-pure-volcanic-assyrtiko, volcanic-slopes-mavrotragano
Tip: Worth combining with a visit to the Akrotiri archaeological site and Red Beach; the southern-exposure style is leaner and more saline than the central-island norm.

PDO SantoriniAssyrtiko, MavrotraganoExo Gonia
Art Space at Exo Gonia combines a working winery with a contemporary art gallery in the structure of a 19th-century canava. The winery produces small-batch Assyrtiko and Mavrotragano alongside rotating art exhibitions in the same cave-cellar complex. The combination of wine and art makes Art Space a distinctive cellar-door visit away from the main caldera-rim tourist circuit.
PDO SantoriniAssyrtiko, Aidani, MavrotraganoMegalochori
Gavalas Winery in Megalochori is a small family producer working with Assyrtiko and rare Aidani-led whites alongside Mavrotragano reds. The estate has been farming Santorini vines for generations and the wines are sold direct from the village cellar with limited distribution beyond Greece.
