Rocky Reach AVA

The name Rocky Reach traces back to 19th-century steamboat captains who used the phrase to describe a rocky, rapid-filled stretch of the Columbia River. Dr. Kevin Pogue, Professor of Geology at Whitman College, submitted the AVA petition in 2018, and the Alcohol and Tobacco Tax and Trade Bureau officially granted designation on June 3, 2022. Rocky Reach became Washington's 20th AVA, one of the youngest appellations in the state.

• Name derives from 19th-century steamboat navigation terminology for the Columbia River
• Petition submitted in 2018 by Dr. Kevin Pogue of Whitman College
• Officially designated June 3, 2022 by the TTB
• Washington's 20th American Viticultural Area

Rocky Reach occupies a deep canyon carved by the Columbia River, straddling the river between Chelan and Wenatchee in Chelan and Douglas Counties. The low-elevation canyon setting, constrained to below 1,600 feet (488 m), creates a microclimate considerably warmer than surrounding areas. Average temperatures sit at 64.7°F (18.2°C), with maximums reaching 77.9°F (25.5°C) and minimums of 52°F (11°C). Annual precipitation is a mere 11 inches, placing the region firmly in warm semi-arid territory. The extended growing season and heat accumulation allow reliable ripening of both red Bordeaux varieties and Rhône grapes.

• Deep canyon topography creates a warmer, longer growing season than neighboring areas
• Elevations restricted to below 1,600 feet (488 m)
• Annual rainfall of only 11 inches; classified as warm semi-arid
• Flat-topped terraces on canyon sides provide ideal vineyard sites

Rocky Reach's geology is what truly distinguishes it within Washington wine country. The surface is loess, windblown sand and silt typical of Columbia Valley, but beneath it lie cobblestones and gravels deposited by glacial outwash and glacial floods. Below that sits a metamorphosed sedimentary and igneous crystalline basement bedrock rich in silica, quartz, and mica. This crystalline foundation is shared only with the adjacent Lake Chelan AVA; the remaining 95% of Columbia Valley sits on basalt bedrock. The cobblestone soils warm rapidly during the day and radiate stored heat back to vines at night, accelerating ripening.

• Loess topsoil overlies cobblestones and gravels from glacial outwash and glacial floods
• Crystalline basement bedrock rich in silica, quartz, and mica
• Shares this rare crystalline geology only with Lake Chelan AVA, not the broader Columbia Valley
• Cobblestones store and radiate heat, promoting faster and more even ripening

Rocky Reach grows a range of red and white varieties suited to its warm, dry conditions. Cabernet Sauvignon, Merlot, Syrah, Grenache, Cabernet Franc, Malbec, Carmenère, and Mourvèdre represent the reds, while Sauvignon Blanc and Viognier anchor the white plantings. The combination of heat accumulation, well-draining cobblestone soils, and minerality from the crystalline bedrock produces bold, structured reds with ripe dark fruit, firm tannins, and balanced acidity. The AVA currently holds approximately 117 acres under vine across seven to eight commercial vineyards, with Rocky Pond Estate Winery the sole winery within appellation boundaries.

• Red varieties include Cabernet Sauvignon, Merlot, Syrah, Grenache, Cabernet Franc, Malbec, Carmenère, and Mourvèdre
• White varieties include Sauvignon Blanc and Viognier
• Only 117 acres under vine across seven to eight commercial vineyards
• Rocky Pond Estate Winery is the only winery physically within the AVA
