To winemaker Landon Donley, the beauty of winemaking is in the details. His intentional, precise practices in every aspect of the vineyard and in the cellar are what allow him to achieve wines that not only capture a beautiful reflection of Napa Valley, the vintage and the varietal, but are beautifully balanced upon release.

Attaining complexity with balance requires meticulous execution. Winemaking here is a gentle, labor-intensive process that draws from both Old and New World styles and techniques, each step designed to emphasize the unique aromatic and varietal personality of each lot of fruit.

Located in St. Helena, our winery is specifically designed to handle each small lot of fruit individually, from harvest to blending. Using state-of-the-art technology and customized pressing, fermentation and aging programs for each lot allows us to craft wines that are beautifully expressive as soon as they are released.
