Shatter is a delicious collaboration between Dave Phinney (Orin Swift Cellars) and Joel Gott.  Highly recommended.

Shatter comes from the small town of Maury in the Roussillon region of France. The hillside grenache vines were planted over 60 years ago in black schist, a slate-like, rocky soil common to the area. Though nutrient-poor, it retains heat well, allowing the slow-ripening grenache to reach full maturity through cool nights. Tough soil, strong winds and hot days push the vines and cause shatter, or coulure, in the grape clusters, naturally thinning fruit from the vines and producing more intensely concentrated flavors. After harvest, the fruit was cold-soaked for 30 days to help further concentrate the wine, then fermented and aged at Dave's winery in Maury.

previous vintage 92 Points Robert Parker:  "A collaboration between Napa's Joel Gott and Dave Phinney, the semi-opaque Cotes Catalanes Grenache is a smoking blend of 100% Grenache that comes from the singular, black schist soils located around the village of Maury, in the Agly Valley in the Roussillon. Aged in French oak (a small part being new) and hitting 15.6% natural alcohol, this sexy, full-bodied, pedal-to-the-metal effort bears plenty of resemblance to the old-vine, 100% Grenache efforts coming from Chateauneuf du Pape. Kirsch liqueur, blackberry, toasted spice, garrigue and hints of vanilla bean all flow nicely to a seamless, silky, yet decadently styled red that has fine tannin, and a blockbuster, heady finish. It will certainly not appease those looking for lightweight aromas and flavors, but count me a fan. The oak is still present, so give it a year in bottle; it will drink nicely for another 5-6 years."
