Goose Gap AVA

Commercial viticulture at Goose Gap began in 1998 when Arvid Monson planted the first vineyard blocks after receiving validation from Dr. Walter Clore, widely regarded as the father of the Washington wine industry. The Monson family, who had farmed the Columbia Valley since the early 1900s, founded Goose Ridge Estate Vineyard and Winery in 1999 and steadily expanded plantings across the site. Alan Busacca, PhD, a leading vineyard consultant and geologist, authored the TTB petition on behalf of the Goose Gap Winegrowers Association. After a proposed rulemaking was published in October 2020, the TTB published the final rule on July 1, 2021, with the designation taking effect August 2, 2021.

• Arvid Monson's vision for the site was validated by Dr. Walter Clore in 1998, leading to the first commercial grape plantings in the AVA
• Goose Ridge Estate Vineyard and Winery founded in 1999 by the Monson family, who had farmed the Columbia Valley since the early 1900s
• TTB petition submitted by Alan Busacca, PhD, on behalf of the Goose Gap Winegrowers Association; proposed rule published October 2020, final rule July 1, 2021
• Goose Gap was the third new Washington AVA approved in 2021, following White Bluffs and The Burn of Columbia Valley, bringing Washington's total to 19 AVAs

Goose Gap's most distinctive feature is the east-west orientation of Goose Hill's crest, which stands in direct contrast to the northwest-southeast alignment of every other nearby ridge, including Red Mountain, Candy Mountain, and Badger Mountain. Because the south and southwest faces of Goose Hill are too steep for planting, virtually all commercial viticulture occurs on the gentler north and northeast-facing slopes, making Goose Gap the only large vineyard development in the lower Yakima Valley planted dominantly on north-facing aspects. Elevations range from 577 feet to 1,339 feet, and the top of Goose Hill rises above the maximum reach of the ancient Missoula Floods, which peaked at approximately 1,200 feet. The region receives about 7 inches of annual precipitation and relies on irrigation.

• Goose Hill's east-west crest orientation is unique among Yakima Fold Belt ridges; all surrounding hills run northwest to southeast, yielding south-facing plantable slopes
• North and northeast-facing slopes receive less solar radiation and produce later ripening compared to south-facing vineyards on Red Mountain and Candy Mountain
• Elevations range from 577 feet (southern boundary) to 1,339 feet (Goose Hill summit); upper elevations exceed the 1,200-foot maximum of the ancient Missoula Floods
• Semi-arid climate with approximately 7 inches of annual precipitation; long, warm days and cool nights during the growing season create significant diurnal temperature variation

The TTB identified geology and soils as the primary distinguishing features of the Goose Gap AVA. Warden series soils, which make up approximately 65% of the AVA, consist of wind-blown loess averaging 20 inches in depth overlying stratified silts and fine sands deposited by the catastrophic Missoula Floods. These soils have rooting depths of six feet or more with no root-restrictive layers, making them highly prized for irrigated viticulture. Together, Warden and Shano series soils cover approximately 85% of the currently planted vineyard area. Other soil series present include Kiona, Hezel, and Prosser, collectively accounting for the majority of the remaining AVA soils.

• Warden series soils = approximately 65% of AVA; wind-blown loess averaging 20 inches deep over stratified Missoula Flood sediments with rooting depths of 6 feet or more
• Warden and Shano series together cover approximately 85% of the planted vineyard area, a concentration higher than in surrounding Yakima Valley or Columbia Valley areas
• Five main soil series account for roughly 95% of AVA soils: Warden, Shano, Kiona, Hezel, and Prosser
• Soils derive from Columbia River Basalt folded by tectonic compression into the Yakima Fold Belt; lava flows originated from the Yellowstone hotspot 10 to 15 million years ago

Goose Gap's 1,800 planted acres cultivate 16 varieties, with Cabernet Sauvignon, Merlot, Syrah, Chardonnay, and Cabernet Franc among the principal varietals. The cooler mesoclimate created by north-facing aspects produces wines that, as winemaker Andrew Wilson has described, preserve freshness and crispness even in red varieties, with clean, bright flavors rather than the big, ripe, jammy profiles more typical of south-facing slope vineyards nearby. Juan Munoz-Oca, former chief winemaker at Ste. Michelle Wine Estates, has described Goose Gap as offering a profile between Yakima Valley freshness and Red Mountain fruit concentration, with the ability to hold acidity alongside a punch of fruit.

• Cabernet Sauvignon: structured but fresh, with cassis, dark plum, and herb notes; north-aspect ripening preserves acidity and avoids over-ripe, jammy character
• Merlot: lush and fruit-driven with cherry, berry, and spice; frequently used as a premium blending component alongside Cabernet Sauvignon in estate programs
• Syrah: gaining recognition for velvety texture and spiced, peppery aromatics reflecting the cool-climate growing conditions of north-facing slopes
• Cabernet Franc and Chardonnay: also planted, with Chardonnay showing floral and citrus character benefiting from the region's diurnal temperature variation

Goose Ridge Estate Vineyard and Winery, founded in 1999 by the Monson family, is the only bonded winery located within the Goose Gap AVA boundary. The family operates the largest contiguous estate vineyard in Washington State at 2,200 acres, all within the AVA. The second commercial vineyard in the AVA is an Aquilini Brands property; Aquilini Family Wines ceased wine production in late 2025, though the vineyard land continues to exist. Goose Ridge fruit is sold to more than 20 regional winemakers across Washington, giving the appellation broader representation in the market than its single resident winery would suggest.

• Goose Ridge Estate Vineyard and Winery: founded 1999, only bonded winery within AVA, operates 2,200-acre contiguous estate vineyard growing 16 varieties
• Goose Ridge produces wines under multiple labels including Goose Ridge Estate, g3, Revelation, Among the Giants, Tall Sage, and Stonecap, all from estate fruit
• Monson family: fourth-generation Columbia Valley farmers with roots in the early 1900s; committed to Sustainable WA certification, a third-party audited sustainability program
• Goose Ridge tasting rooms in Richland (estate), Woodinville, Walla Walla, and Leavenworth provide primary consumer access to Goose Gap wines

Goose Gap AVA operates under standard federal AVA regulations requiring a minimum of 85% of a wine's fruit to originate within the appellation boundary for label designation. Vintners whose wines qualify may choose among three appellations of origin: Goose Gap, Yakima Valley, or Columbia Valley, as Goose Gap lies entirely within both larger AVAs. Since August 2, 2021, wineries have been able to submit Certificate of Label Approval requests to the TTB designating Goose Gap as the appellation of origin. No varietal restrictions or production minimums are prescribed by the AVA designation itself; all such decisions remain at the producer's discretion.

• Federal minimum = 85% of fruit from within the Goose Gap AVA boundary to use the designation on a label
• Wines may alternatively carry Yakima Valley or Columbia Valley designations, as Goose Gap lies entirely within both larger AVAs
• COLA requests designating Goose Gap appellation of origin accepted by TTB from August 2, 2021 onward
• TTB designated geology and soils (not climate) as the primary distinguishing features in the official rulemaking, as the petition lacked climate data from within the proposed AVA itself
