September 21st is International Grenache Day, which got us thinking of all the yummy GSM (Grenache/ Syrah/ Mouvèdre) blends out there. Though originating in the Southern Rhône region of France (Châteauneuf-du-Pape, anyone?), that's not the only place to find these fruity, spicy, persistent and delicious blends. There's also Washington State, Paso Roble in California, Spain, and Australia. All delicious, all with their own unique style.
