Quattro Theory

Four Elements to Deliver an Exceptional Wine

Nestled in the heart of St. Helena, Quattro Theory Winery has established itself as a producer of premium Napa Valley wines that beautifully balance power and elegance. The winery specializes in terroir-driven Cabernet Sauvignon and Chardonnay, showcasing the distinct characteristics of Napa's most coveted growing regions. Quattro Theory means an ideal set of four elements combined to deliver an exceptional wine: Vision, Quality Vineyards, Precision Winemaking and Experience.

Under the guidance of winemaker Landon Donley, Quattro Theory employs a precision-focused philosophy that blends traditional techniques with modern innovation. Each small lot receives individualized attention through: Hand-harvesting at optimal ripeness, gentle whole-berry fermentation for enhanced aromatics and extended aging in premium French oak barrels

The winery's Cabernet Sauvignon artfully combines fruit from St. Helena's valley floor with mountain vineyards on Mt. Veeder and Atlas Peak, creating wines with depth, structure, and aging potential. Their Carneros-sourced Chardonnay displays the perfect balance of vibrant acidity and rich texture.
