Douro Valley 1966 Vintage Report

For much of the season, 1966 looked destined for greatness in Douro Valley, until the elements conspired against it in the final weeks.

Spring was steady if unremarkable, with the vines navigating the vulnerable flowering stage without major incident.

The growing season was solar and generous. Accumulating 2058 Growing Degree Days (GDD), the summer provided consistent warmth that drove steady sugar accumulation.

The finale was fraught with tension. A deluge of 159mm 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.
