Napa Valley’s Spring Mountain District lies up to 2,600 feet along the eastern slopes of the Mayacamas Range, receiving influences from the Pacific coast that create a cool to moderate climate for viticulture. Many vineyards in the wine appellation sit above the fog line, where cool daytime and warmer nighttime temperatures regulate the development and ripening of grapes. Well-drained soils and geographical diversity, including its topography of varying elevations and aspects, also provide distinct pockets for fruit to flourish.

The 2015 vintage brought drought and heat stress to the vines this year and led to a challenging harvest for many Spring Mountain growers. Lower yields of outstanding quality fruit resulted in wines of superb concentration.
