Stonestreet is a testament to the ascendant quality of mountain viticulture. Planted in the mountain above the Alexander Valley appellation, at 400 feet to 2,400 feet in elevation, the estate stands as one of the largest, most diverse mountain vineyards in the world. Here, at the limits of grape-growing, winemaker Graham Weerts produces single vineyard estate Cabernet Sauvignon and Chardonnay that demonstrate the wow factor and aging potential of wines made from high-elevation fruit. These intensely structured wines are sourced from only the finest blocks in the vineyard – a site that is on its way to becoming its own appellation, Pocket Peak. Stonestreet also produces single-vineyard wines that, together with their estate wines, paint a harmonious expression of the mountain in all its complexity.

Exceptional Winemaking Rooted in Viticulture

Graham Weerts always knew he wanted to work in agriculture. He was raised in a farming family in Cape Town, South Africa, and drawn to the vines along the mountainsides of the Western Cape. He received a degree in Viticulture, Wine Science and Pomology at Elsenburg College, the first agricultural college of its kind in South Africa.

Graham worked for the iconic Mulderbosch Vineyards in Stellenbosch and was one of the first South Africans to work in Europe during harvest with Château de Terrefort-Quancard in Bordeaux. In 1999, he arrived in Sonoma County for a formative vintage at Vérité Winery, and returned in 2004 as head winemaker for Stonestreet Estate Vineyards.

More than 15 years later, Graham continues to apply his global perspective and expertise with high-elevation winegrowing to produce the wines at Stonestreet Estate Vineyards. He is also the winemaker for Capensis and oversees winemaking operations for Jackson Family wineries in Sonoma County.

Rooted in Family. Focused on the Future.

Stonestreet is named after Jess “Stonestreet” Jackson, the winery's founder, who, along with his wife Barbara Banke, purchased the estate in 1995. Their vision was to defy the limits of California winegrowing and establish a world-class estate for generations to come. Today, the estate’s legacy continues under the leadership of Jess and Barbara’s youngest son, Chris Jackson and his wife, Ariel Jackson. Chris spent the first 20 years of his life on the mountain, which is where he first learned how to prune a vine. How cool is that?
