GSM is shorthand – 1980s Australian shorthand – for a classic Rhone blend of three grapes – Grenache, Syrah and Mourvedre. The basic formula will vary from year to year as one grape stands out over the others. The 2006 contains 45 percent grenache, 33 percent syrah and 22 percent mourvedre. The nose is full of cedar, cherries and berry fruit. The fruits are dry in the mouth with no residual sweetness but lots of flavor and acids that show off the brightness of the grenache and yet allows the spiciness of the syrah to display itself on the back of the palate.
The syrah is the part that would make this a great wine for a steak au poivre – steak with a pepper sauce. As great as this wine is right now, it can lift the gloom of a winter’s night alongside a stew or a standing rib roast. Try it instead of a cabernet sauvignon. The Halter Ranch GSM should age nicely over the next several years if you can’t decide on the perfect occasion.
