Every Summer the wine grapes grown in the Napa Valley go through a process called véraison whereby the ‘berries’ go from a growth stage to a ripening stage.
This year, veraison has come a bit later than usual due to the super mild Summer weather we’ve experienced. Mornings have seen us largely socked-in with fog with temperatures hovering in the low 50s. The sun generally breaks through around mid-day, but the overall warm-up has been on the cooler side (lots of 70s and 80s), leading to a slower ripening process for the valley’s most important crop.
While not an issue now, the cool Summer and slower ripening could be cause for concern as Summer turns to Fall and the threat of rain or even colder temperatures increases.
Here are a few photos from today showing the véraison process in action in the Oak Knoll District.
