Cline operates in Los Carneros, the cool-climate region that straddles Napa and Sonoma counties. The appellation's maritime influence and diurnal temperature swings shape wines of precision and balance. The winery's Diamond Pile Vineyard Single Vineyard Series Pinot Noir demonstrates the region's capacity for structured, age-worthy expressions of the variety. A Late Harvest Mourvedre shows the winery's range beyond the cool-climate norm, while its Chardonnay reflects Los Carneros' reputation for elegant, mineral-driven whites. Wine Enthusiast, Wine Advocate, Decanter, and Wine Spectator have all assessed Cline's portfolio, offering critical perspective on its output across red and white varietals.
