GSM is a classic red wine blend from the South of France, namely the Rhône valley. The acronym “GSM” comes from the grape names that make up the primary ingredients: Grenache, Syrah, Mourvèdre. It also indicates the percentages of each wine that makes up the final blend; although exact percentages will vary from year to year (depending on a particular vintage’s quantity and quality of yield), traditionally there will be the highest amount of Grenache, followed by Syrah, and finally Mourvèdre.
But because wine blending (and winemaking in general) is equal parts art and science, vintners will spend days, weeks, maybe even months perfecting their final blend. If you have a chance to participate in this art project/science experiment, do it. It’s an opportunity to learn about the importance of vintage and terroir, harvest and winemaking methods, individual grapes and final blends.
In my book, you can’t call yourself a Rhone Ranger unless you make a decent GSM. Look at the fine print in my book and it also says that those individual components have to shine on their own — Grenache, Syrah, Mourvèdre. Well, if you look in the glossary of my book under Rhone Ranger, you’ll see a picture of Steve and Brian of Crux Winery. Not only do they do justice for the Rhone-style, but they grow and produce these typically warm-weathered grapes in the heart of Northern California’s Russian River Valley.
Crux Winery is by far one of my favorite boutique wineries. They’re certainly setting the pace when it comes to Russian River Rhone wines — big bold flavors that are elegantly refined into some of the most balanced wines one can taste in the Rhone style. They’re the epitome of Old World conceptions meeting New World style. And the 2015 GSM Rosé is a palate-pleaser that proved just that.
