One of the hottest categories in Northwest wine is red blends. And red blends made in the style of France’s Rhone Valley are among the most fascinating.

Referred to as “GSM” blends, the wines are most often made with the red Rhone grapes Grenache, Syrah and Mourvedre, though they also can include Cinsault, Counoise, Carignan and Petite Sirah.

In the spring issue of Wine Press Northwest magazine, we take a look at a variety of red Rhone varieties, particularly GSM-style blends.

These are among the best examples we tasted during a blind judging for the publication. These wines are made in small amounts, so check with your favorite wine merchant or contact the wineries directly.
