Willamette Valley 1966 Vintage Report

Defining the 1966 vintage in Willamette Valley requires looking beyond the averages, as it was a year of contrasting fortunes and precise timing.

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

It was a cool, classical season. Reaching only 1172 GDD, the summer never really spiked in temperature, favoring the development of fresh aromatics over sheer power. A key factor was the dramatic diurnal shift (12.3°C), ensuring that despite the daytime warmth, acidities remained razor-sharp.

Harvest proceeded under mixed skies, requiring agility to dodge the 64mm of rain that fell sporadically during the picking weeks.

**Style:** Classically proportioned wines with good balance and terroir expression.
