Napa Valley 2020 Vintage Report

Defining the 2020 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 25 days soaring above 35°C, the vines faced a stress test. Combined with a lack of rainfall (only 56mm 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 (15.5°C), ensuring that despite the daytime warmth, acidities remained razor-sharp.

The season concluded with a pristine harvest window. With negligible rain (0mm), pickers could wait for perfect phenolic maturity, harvesting each block at its absolute zenith.

**Style:** Rich, opulent, and structured wines built for the long haul.
