Gaia is a winemaker based on Santorini in the Aegean Islands, producing white wines from the island's volcanic terroirs. The producer works primarily with Assyrtico, the native white variety that defines Santorini's modern wine identity.

Santorini's PDO designation encompasses vineyards planted on the caldera of an active volcano, where the soil composition of volcanic ash, pumice, and mineral deposits creates distinctive growing conditions. The island's exposed position in the Aegean results in strong maritime influence and intense sunlight, factors that shape the character of wines produced here. Assyrtico thrives in these conditions, developing high acidity and mineral concentration that are hallmarks of serious Santorini white wine.

Gaia's current range includes wild ferment expressions of Assyrtico, an approach that allows the wine's natural acidity and mineral profile to develop without temperature control or commercial yeast inoculation. This style emphasizes the specific character of the vineyard and vintage rather than consistency across releases.

PDO Santorini is a protected designation of origin located on the volcanic island of Santorini in Greece's Aegean Islands. The appellation covers vineyards situated on this crescent-shaped island, which was formed by ancient volcanic activity that created its distinctive caldera landscape.

The terroir of Santorini is defined by its unique volcanic soils composed of pumice, ash, and lava, combined with intense sunshine, strong winds, and minimal rainfall. Assyrtiko is the primary white grape variety permitted under the PDO regulations, though other indigenous varieties like Athiri and Aidani may also be used. The harsh growing conditions and volcanic terrain produce low yields, with vines often trained in distinctive basket-shaped formations called kouloura to protect against the persistent winds.

Wines from PDO Santorini, particularly those made from Assyrtiko, are characterized by high natural acidity, mineral intensity, and remarkable aging potential. The volcanic soils impart a distinctive saline minerality to the wines, while the grape's thick skin helps retain acidity despite the Mediterranean climate. These wines typically display citrus and stone fruit flavors underpinned by pronounced mineral notes and a characteristic volcanic smokiness.
