Tenet Wines 2013 GSM, Columbia Valley, $70

Tenet Wines-2013-GSMSte. Michelle Wine Estates adds to its international “string of pearls” experience with Tenet Wines, its palindrome-coined collaboration with renowned Rhône Valley vintners Michel Gassier and Philippe Cambie. Their inaugural vintage in Washington state with Chateau Ste. Michelle head winemaker Bob Bertheau results in this delicious and mildly hedonistic GSM-style blend of Grenache (40%), Syrah (35%) and Mourvèdre aged 12 months in 100 percent neutral French oak barriques (86%) and puncheons (14%). Its nose of Marionberry taffy, huckleberry, red currant, Western serviceberries and dark chocolate carries on through to the palate, where mild tannins and elderberry juice make for a rich, yet bright finish.

    Syncline “Subduction Red” needs to be included, in part, because it has the 3 GSM + Cinsault & Carignan.

    Covington Cellars ” MA Belle”should be included. Cinsault has been been added to the 2013 GSM blend. A most appealing wine.
