Volcanic soils are geological formations derived from volcanic activity, formed through the weathering of lava, ash, pumice, and other pyroclastic materials. In viticulture, these soils are valued for their ability to impart distinctive qualities to wines, particularly in regions such as Etna, Santorini, and the Canary Islands.[1]
Background
Volcanic soils are present in many winegrowing regions across Europe and the New World, often associated with dramatic landscapes and historical viticulture. In Italy, Sicily’s Etna DOC has become emblematic of volcanic terroirs, while in Greece, Santorini’s vineyards are rooted in ancient volcanic deposits shaped by the Aegean eruptions.[2] Outside Europe, examples include the Azores and Canary Islands in the Atlantic, and volcanic zones in California and Oregon.[3]
Characteristics
Volcanic soils are heterogeneous, consisting of basalt, tuff, pumice, and other igneous rock fragments. They are typically well-drained yet retain sufficient moisture due to their porous structure. Their high mineral content, particularly in elements such as iron, magnesium, and potassium, influences vine nutrition.[4]
These soils warm quickly during the day and can radiate heat during cooler nights, helping to extend ripening in marginal climates. However, they can be challenging for vine establishment, as their rocky texture requires deep root penetration and adaptation to low fertility.[5]
Role in Viticulture and Winemaking
Volcanic soils often produce wines of notable freshness and distinctive mineral character. On Etna, red wines from Nerello Mascalese and white wines from Carricante are renowned for their high acidity and savoury, smoky notes.[6] Santorini’s Assyrtiko thrives in volcanic ash and pumice, yielding wines with pronounced salinity and longevity. In the Canary Islands, old-vine Listán Negro and Listán Blanco planted in volcanic craters and lapilli soils produce uniquely aromatic wines.[7]
While the concept of “minerality” remains debated, many winemakers and consumers associate volcanic terroirs with distinct textural and aromatic qualities. These sites, often difficult to farm, are increasingly celebrated as contributors to terroir-driven wine styles.[8]
