- Established in 2016
- Formed by the Snake and Clearwater rivers, the Lewis-Clark Valley AVA consists of canyon side and bench lands and 85,238 acres lie in Washington while 220,332 acres lie in Idaho.
- About 72% of the Lewis-Clark Valley AVA is located in Idaho, the rest in Washington.
- Known as the “banana belt,” the Lewis-Clark Valley is known to be a temperate climate within the colder surrounding regions this produces high quality fruit trees such as peaches, apples, wine and table grapes. Currently, the Lewis-”Clark Valley AVA is home to 16 vineyards growing more than 81 acres of grapes.
- The AVA would be the first and only AVA in Idaho or Washington to be nestled in the unique mountainous backbone of northern Idaho, the Bitterroot Mountains.
- 14 varieties of red wine grapes and nine varieties of white wine grapes are currently grown and sold in the vineyards of the AVA.
- The geology of the AVA has good planting areas that are easy to develop and contain air drainage characteristics, ideal for wine grapes. They also contain steep sides with shallow stony surficial cover for more classic and exotic vineyard sites.
- The Lewis-Clark AVA is Washington’s fourth cross-state AVA (others include Columbia Valley, Columbia Gorge and Walla Walla Valley)
The Lewis-Clark Valley AVA’s soil is comprised of decomposing perennial grasses and grass roots with capacity to hold water. The majority of soils contain loess, or wind-deposited, nutrient-rich silt. The region has good planting areas that are easy to develop and contains air drainage characteristics that are ideal for wine grapes. It also contains steep sides within shallow, stony surficial coverage for both classic and exotic vineyard sites.
The Lewis-Clark Valley is nicknamed the “banana belt” because of its temperate climate amid colder surrounding regions. This climate produces high quality fruit trees, such as peaches, apples, wine and table grapes.
Precipitation in the Lewis-Clark Valley is sufficient enough in areas to require only minimal irrigation. It is directly below originating watersheds of the Palouse and Camas Prairies. The steep V-shaped valley allows for good drainage, providing frost protection and cool nighttime temperatures for acid retention and flavor development. The annual precipitation varies between 11-22 inches.
