Alexander Valley AVA
A narrow valley extending from Healdsburg to Cloverdale, Alexander Valley (officially established as an AVA in 1984) is Sonoma County’s warmest appellation, which is the biggest reason why cabernet thrives here and not in Sonoma’s cooler, more coastal regions. The hot, dry summers, early morning fog, and gravelly, well-draining soils lead to a slow and long ripening of the grapes – just the way cabernet growers like it. A majority of cabernet vines in Alexander Valley are planted at higher elevations (up to roughly 2,500 ft.) on the region’s benchlands, rolling hillsides, and Mayacamas mountain range. This means greater sun exposure, but also more stressful soil conditions, which are two major ingredients to producing a quality crop.
“Cabernet sauvignon thrives in the rocky, red volcanic soil that forces the vines to struggle and develop deep roots. The hardy underground systems channel valuable nutrients to the grapes and create fruit brimming with power, spice, and complexity,” says Karin WarneliusMiller, co-owner of Garden Creek Vineyards in the Alexander Valley.
Alexander Valley also has a little something extra that makes it ideal for producing cabernet. Pacific breezes coming from both the Russian River Valley and Sonoma Coast add a unique cooling element that gives Alexander Valley wines their signature acidity. As a whole, this terroir produces wines that are age-worthy and beautifully balanced: dark in color, powerful yet elegant in structure, and high in acid. Notes of black fruit, dried herbs, and tobacco are common.
