Tenet GSM Red Blend is a bold, elegant Washington State wine from the Columbia Valley, crafted as a collaboration between Chateau Ste. Michelle's winemaking team and Rhône Valley luminaries Michel Gassier and consulting oenologist Philippe Cambie. The blend is composed of 50% Grenache, 24% Mourvèdre, 24% Syrah, and 2% Cinsaut, reflecting the Rhône-style winemaking tradition translated to the Pacific Northwest terroir.

One third of the wine undergoes whole cluster fermentation, and the finished wine is aged for 15 months in a combination of neutral (60%) and new (40%) French oak 500-liter puncheons and 600-liter demi-muids. This thoughtful approach yields a wine of elegance and finesse that opens with savory aromas of berries, spice, leather, black pepper, and delicate floral notes. On the palate it is smooth, juicy, and full-bodied, finishing dry and long with a pleasantly grippy structure. Alcohol is 15.5%.
