Vineyard

Sierra Bonita Vineyards is a small estate vineyard located at 17251 West Ash Creek Road, approximately 22 miles northwest of Willcox, Arizona, in the fertile Sulphur Springs Valley of Graham County at an elevation of about 4,300 feet. Nestled near the historic Sierra Bonita Ranch established in 1872, the roughly 10–11 acre vineyard was planted in the late 1990s and benefits from the region’s high-desert climate—characterized by warm days, cool nights, and rich agricultural soils well-suited for full-bodied red varietals such as Mourvèdre and Aglianico. The site features a scenic, high-elevation setting that supports sustainable, hands-on viticulture practices in Arizona’s emerging Willcox wine region. Today the vineyard continues as a quiet agricultural property within southern Arizona’s growing wine country.

The Grapes

Aglianico grapes at Sierra Bonita Vineyards are well-adapted to the high-desert terroir of the Sulphur Springs Valley near Willcox, Arizona. Grown as part of the small 10–11 acre estate at an elevation of approximately 4,300 feet, these vines take advantage of intense sunlight, warm days, cool nights, and the area’s fertile soils. The variety yields small, thick-skinned berries that develop bold structure, deep color, and complex notes of dark fruit, dried herbs, and earth—characteristics that reflect the challenging yet rewarding conditions of Arizona’s Willcox region. The Aglianico blocks continue to contribute distinctive, age-worthy fruit to select Arizona winemakers
