There’s a dusty book someplace that lists the California harvests that ran earlier than 2013, but I can’t recall many in the 24 years I’ve lived here. Consider this. Hanzell Vineyards, known for great Pinot Noir and Chardonnay, finished its harvest in Sonoma Valley a week before Labor Day.
That’s on the outskirts of the norm but it does show how fast things are moving. The growing season rain early all year and there’s been plenty of sun throughout summer. Warm temperatures to start the month moved things along even faster.
