Volcanic Soils
🔍 Quick Summary
Volcanic soils shape wine by imparting vibrant acidity, intense minerality, and a tension that often mirrors the rugged, ancient forces beneath the vineyard.
🍇 What It Is
Volcanic soils are born from ash, lava, and other eruptive materials that have broken down over millennia. These soils can range from black basalt to pumice, tuff, and decomposed lava rock, often retaining heat and draining water quickly. Found in regions with past or present volcanic activity—like Sicily, the Canary Islands, Santorini, and parts of Oregon—they offer a dramatic and nutrient-rich foundation for vines.
🌍 Why It Matters
Volcanic soils tend to be low in organic material but rich in minerals like iron, magnesium, and potassium. This creates moderate stress for the vines, encouraging deep root systems and slower, more balanced ripening. Their good drainage keeps roots healthy, while their heat retention can extend ripening in cooler climates. In some regions, these soils also insulate vines from pests like phylloxera.
🍷 In the Glass
Wines from volcanic soils often display high acidity, pronounced minerality, and a lifted, almost electric quality. They can show notes of flint, smoke, or salty tension, especially in white wines. Think Etna Rosso from Sicily volcanic-grown Nerello Mascalese with nervy structure and wild herbs or the zesty Assyrtiko from Santorini, grown in pure volcanic ash. Oregon’s Eola-Amity Hills Pinot Noir also shows how volcanic soils can shape texture and depth.
