Calluna Vineyards, nestled in the Chalk Hill appellation of Sonoma County, California, is known for its Bordeaux-inspired wines crafted from estate-grown grapes. Founded and operated by David Jeffrey, the vineyard encompasses 17 acres, initially planted in 2005 with Cabernet Sauvignon, Cabernet Franc, Merlot, Petit Verdot, and Malbec, and expanded in 2014 to include Sauvignon Blanc and Semillon for their white wine production. Jeffrey's winemaking philosophy aims for a balance between the structure and longevity of Bordeaux wines and the richness and approachability found in top Sonoma and Napa wines, focusing on natural winemaking practices facilitated by the region's moderate climate and favorable soils.
