Marking the warmest year since 2008, the 2015 growing season set a record for early bloom. Drought conditions persisted, and rainfall was erratic, with most of the much-needed rain falling at the end of the previous year and supplemented by only a single storm in February, which was enough water to sustain the vines. Cooler conditions during flowering ultimately lead to a smaller number of berries on each cluster and lower than average yields. Warm summer months led to advanced veraison, which was followed by perfect ripening conditions.
