Jess Jackson and Barbara Banke established the Alexander Mountain Estate in 1995 as a test of what California could do at altitude. 5,300 acres rise from the valley floor into the Mayacamas, with 170 micro-vineyards between 400 and 2,400 feet across 26 soil types. Cabernet and Chardonnay built by altitude.
Stonestreet Estate farms nearly 5,500 acres of mountain terrain in the Mayacamas range above Alexander Valley — one of the largest single estate holdings in Sonoma County. The high-elevation sites produce Cabernet Sauvignon and Chardonnay of considerable structure and longevity, shaped by volcanic and sedimentary soils and dramatic diurnal temperature swings. The Bear Point and Christopher's Vineyard single-vineyard bottlings are the most serious expressions in the portfolio. The estate is part of the Jackson Family wines portfolio but operated independently.
Estate Cabernet Sauvignon, Alexander Valley — A blend of the finest mountain blocks across the Alexander Mountain Estate.
Rockfall Vineyard Cabernet Sauvignon — A powerful high-elevation single-vineyard Cabernet (95+ points).
Christopher's Cabernet Sauvignon — A structured, mountain-grown estate Cabernet.
Upper Barn Chardonnay — A celebrated single-vineyard mountain Chardonnay (98 points).
Estate Chardonnay, Alexander Valley — A soulful blend of the estate's best Chardonnay sites.
Jess Stonestreet Jackson and Barbara Banke established the Alexander Mountain Estate in 1995 as a deliberate test of what California winegrowing could do at altitude. The property is vast — roughly 5,300 acres rising from the valley floor into the western flank of the Mayacamas — but only a small fraction is farmed. Across peaks, valleys, ledges, and ridges, 170 distinct micro-vineyards sit at elevations between 400 and 2,400 feet, planted in 26 different soil types. The focus is Cabernet Sauvignon and Chardonnay, with small amounts of Sauvignon Blanc, and the character is unmistakable: concentrated, structured, built by the altitude and the rocky ground. The tasting room on Highway 128 pours a four-wine mountain flight daily; the Mountain Excursion, offered in the morning and early afternoon, takes six guests on a private guided drive up into the vineyards and tastes the wines where they were grown.
Kristina Shideler is the winemaker at Stonestreet Estate Vineyards, the mountain estate in the Mayacamas above Alexander Valley that is part of the Jackson family's holdings. Born in San Diego and raised in Missouri — home of America's first recognized AVA — she double-majored in biochemistry and agricultural economics at the University of Missouri before devoting herself to high-elevation winemaking. At Stonestreet she champions a patient, mountain-driven style built around estate Cabernet Sauvignon and Chardonnay grown on steep, rugged ridgetop blocks, crafting structured wines designed to unfold over decades.
Christopher Jackson, with his wife Ariel, leads Stonestreet today — the second generation to steward this vast mountain estate above the Alexander Valley. He carries the family’s middle name, “Stonestreet,” passed from his grandfather to his father, vintner Jess Stonestreet Jackson, and now to him. Jess and his wife Barbara Banke established Stonestreet in the 1990s on the former Gauer ranch, naming it for Jess’s father. Christopher oversees roughly 170 micro-vineyards across some 5,300 acres — most left unplanted and wild — drawing powerful single-vineyard Cabernet and Chardonnay from one of the world’s most diverse high-elevation estates.
