Reviews · Napa Valley 2010 Switchback Ridge Anniversary Blend Peterson Family Vineyard 3 notes Most recent 27 October 2017 ProducerSwitchback Ridge WineAll vintages RegionCalifornia · Napa Valley GrapesRed Blend Tasting history Every note on this bottle 27 October 2017 Cedar, damp moss, and wet garbage on the nose. The palate was dead and flat with a slight vinegar aftertaste. 17 December 2016 Good. Not astounding. A cedar aftertaste distracted from the core fruit. Time in a decanter for an hour or two helped, but I'm not sure if this will… 27 December 2015 Slow O2 over the course of 5 hours. Up front notes of plush, ripe plum, black raspberry, blueberry, chocolate/mocha, and a hint of anise.
