(Wines&Vines) - After the announcement last week that veraison is happening in some Napa Valley vineyards, Wines & Vines asked sources in other areas how their grapes are faring so far this summer. Veraison has also begun in the vast Paso Robles region.

At Halter Ranch in the Adelaida District, vineyard manager Lucas Pope reported that it is just starting, with color on about 10% of the ranch, putting it on par with 2015, or about 3 weeks earlier than average.

In El Pomar District, Still Waters Vineyards experienced 11 days with temperatures exceeding 100°F the last two weeks of June, an unusual condition that stressed early-ripening varieties, producing smaller berry size. According to owner and winemaker Paul Hoover, this is on track with the 2014 vintage, the earliest on record.
