What type of soil is found in Santorini?

Santorini is known for its unique volcanic soils, which are a key factor in the region's viticulture. These soils are formed from the ash and volcanic rock produced by eruptions, contributing to the mineral richness and drainage properties that are beneficial for grape growing. The high porosity of volcanic soils allows for excellent drainage, which is particularly advantageous in Santorini's arid climate where water retention is limited.

The mineral composition of volcanic soils can impart distinctive flavors and character to the wines produced in the region, which is essential for the local varieties such as Assyrtiko. This type of soil also affects vine health, supporting their resilience to the harsh conditions found in Santorini. Therefore, the presence of volcanic soils is a defining feature of the terroir in Santorini, greatly influencing its wine production.
