Napa Valley 2007 Vintage Report
Defining the 2007 vintage in Napa Valley requires looking beyond the averages, as it was a year of contrasting fortunes and precise timing.
The cycle began with a harmonious flowering period. Warm days (avg 21°C) allowed for an even fruit set, establishing the potential for a generous crop.
Summer turned up the intensity. With 12 days soaring above 35°C, the vines faced a stress test. Combined with a lack of rainfall (only 88mm total), this led to hydric stress that halted ripening in younger vines, though old vines with deep roots persevered. A key factor was the dramatic diurnal shift (14.1°C), ensuring that despite the daytime warmth, acidities remained razor-sharp.
Harvest proceeded under mixed skies, requiring agility to dodge the 44mm of rain that fell sporadically during the picking weeks.
**Style:** Classically proportioned wines with good balance and terroir expression.
