The unseasonably warm temperatures in the early growing season in the Napa Valley in 2015 resulted in early bud break and bloom. Colder temperatures later in the season caused uneven fruit set and resulted in a smaller crop than previous average yields. Winemakers and vineyard crews worked diligently to pick and sort the best berries. While drought was still a concern for most of California, Napa Valley received 75% of normal rainfall for the year.
The grapes were hand-picked between September 22 and October 7 and went through extended maceration with an average of 44 days on skins. The wine was barrel aged for 20 months in 58% new French Oak.
