Volcanic wines are beginning to get a lot of attention in the wine world these days. This increased interest in wines grown on volcanic soils is partly the result of a generation of wine drinkers looking for new and unusual flavors and varietals.
For those who make and love wine, it’s a compelling topic. Experts agree that the soil in which grapevines grow has a substantial impact on the character of the grapes those vines produce.
Named for a volcanic caldera lake centered on the Clear Lake Volcanic Field, Lake County features some of the youngest volcanic soils in California. Two volcanoes dominate the landscape: Cobb Mountain on the northern slopes of the Mayacamas mountain range; and Mt. Konocti, towering over Clear Lake. Both are home to high-elevation vineyards.
Although the soils across the county are mainly volcanic in origin, the presence of rust-colored volcanic dirt is particularly notable in the Red Hills and High Valley AVAs.
Lake County’s landscape is dominated by Mt. Konocti and other mountains in the Clear Lake Volcanic Field. Lying next to Clear Lake, the Volcanic Field consists of lava domes, cinder cones, and maars with a powerful magma chamber beneath.
When Mt. Konocti last erupted about 11,000 years ago, it created what are today the youngest volcanic soils in the North Coast region of California. These soils are well suited for Cabernet Sauvignon, producing wines of complexity and finesse.
