Napa Valley 1972 Vintage Report
For much of the season, 1972 looked destined for greatness in Napa Valley, until the elements conspired against it in the final weeks.
The cycle began with a harmonious flowering period. Warm days (avg 20°C) allowed for an even fruit set, establishing the potential for a generous crop.
The growing season was solar and generous. Accumulating 1987 Growing Degree Days (GDD), the summer provided consistent warmth that drove steady sugar accumulation. A key factor was the dramatic diurnal shift (14.1°C), ensuring that despite the daytime warmth, acidities remained razor-sharp.
The finale was fraught with tension. A deluge of 94mm during the harvest period forced an expedited picking schedule to mitigate botrytis risks, rewarding those who sorted ruthlessly.
**Style:** Powerful but variable, with the best wines balancing the heat with careful selection.
