PDO Santorini / PDO Vinsanto / PGI CycladesAssyrtiko, Aidani, MavrotraganoFounded 1994Yiannis Paraskevopoulos and Leon KaratsalosWinemaker Yiannis ParaskevopoulosExo Gonia
Founded 1994 by Yiannis Paraskevopoulos (wine scientist and Master of Wine candidate) and Leon Karatsalos. Gaia operates two estates: the Santorini cellar at Exo Gonia and a second at Koutsi in Nemea.
Tasting: Walk-in and bookable tastings at the Exo Gonia cellar, including flights focused on Thalassitis (the cuvée briefly aged on the seabed in the Wild Ferment programme), Wild Ferment Assyrtiko, and Mavrotragano.
Signature wines: gaia-thalassitis, gaia-wild-ferment, gaia-thalassitis-submerged
Tip: Thalassitis Submerged (aged in steel cages on the Aegean seabed) is the Gaia headline experience; the standard Thalassitis bottle is a long-running PDO Santorini bottling that pairs well with grilled fish.

Exo Gonia estate built by Artemis Karamolegos in 2004 on family vineyard parcels, with cellar door and the Aroma Avlis restaurant on the same site.
Tasting: Walk-in and reserved tastings year-round; on-site Aroma Avlis Food and Wine restaurant pairs the estate's bottlings with farm-to-table Mediterranean cooking.
Signature wines: karamolegos-assyrtiko-34, karamolegos-nykteri, karamolegos-mavrotragano
Tip: Book a winery visit with lunch at Aroma Avlis on the cellar terrace; the Assyrtiko 34 (older-vines bottling) is the standout dry white.
PDO Santorini / PGI CycladesAssyrtiko, Aidani, MavrotraganoFounded 1999Antonis ArgyrosWinemaker Antonis ArgyrosExo Gonia
Dual gallery and winery opened by Antonis Argyros in 1999 inside the 1861 family canava at Exo Gonia. Small production (a few thousand bottles) of estate-grown Assyrtiko, Aidani and Mavrotragano alongside rotating contemporary art exhibitions.
Tasting: Year-round; tastings combined with the on-site sculpture and painting gallery. The space is built into the 1861 Argyros family canava at Exo Gonia.
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.
