18276 Hwy 128 Unit: A Nestled in Sonoma County's prestigious Knights Valley AVA, Pelkan Ranch spans 66.7 acres just six miles from downtown Calistoga. Acquired by John and Carolyn Pelkan in 1985, the estate features 21.31 acres of meticulously planted vineyards known for world-class viticulture. Set against Mount St. Helena, it shares a prized ridgeline with Peter Michael Estate Vineyard. At elevations up to 950 feet, vines thrive in iron-rich volcanic soils, producing bold, expressive fruit. Pelkan Ranch grapes appear in acclaimed wines from Chiron, Keplinger, Carlisle, and Trinitas, offering intense red berry, bramble, plum, leather, graphite, and mineral notes. The property includes a charming guest or manager's home and a flat building pad with extraordinarily expansive views. Surrounded by boutique wineries, rolling vineyards, and rural estates, Pelkan Ranch is a rare opportunity for vintners or collectors to own a piece of California wine country heritage.
