Humans and beavers are the only two mammals that alter their environment to suit their needs. Humans are the only ones that do it, on a large or small scale, out of curiosity AND necessity. Marselan, a hybrid-crossing of Grenache and Cabernet Sauvignon, is one of those environmental tweaks that hasn't had much impact on the world, but it looks like it may actually be catching on. Hybrid grape varieties are genetic oddities created to result in a grape with specific characteristics. Playing with Mother Nature in this usually just results in an identity crisis of the Hermaphroditic sort.
An Unlikely Union
Marselan was created in 1961 in France. You might be wondering why such a variety doesn't fit into the realm of genetically engineered grains that Europeans so famously calumniate (is dwarf wheat really so different from a man-made crossing of two grape varieties? Grenache and Cabernet Sauvignon are not native to the same regions, and so would never have reproduced with each other on their own). Not that Marselan is so warmly embraced by French growers, though there is no suspicion surrounding it in comparison to other more genetically modified plants. Grape varieties naturally procreate through cross-breeding: a strapping and multi-faceted grape like Cabernet Sauvignon comes from the union of Cabernet Franc and Sauvignon Blanc in what I hope was a particularly torrid affair. Marselan is a botanical researcher's attempt to combine the breadth and heat-tolerance of Grenache with the lithe but muscular and well-structured qualities of Cabernet Sauvignon. Oh, and they wanted the vine to yield heavily at harvest...my favorite thing. As never fails to be the case, things didn't go as planned.
The Main Character
I've now had four wines made of Marselan (one of which was a blend), which is a relatively wide sample in the scheme of Marselan. They each have a few characteristics in common: Marselan is a medium-bodied wine that lacks the sense of an endoskeleton that Cabernet almost always has (unless it's been heavily manipulated), it's fruit is not so cherry-oriented as Grenache commonly is, and the vine does not yield any heavier than either parent variety. Or looking at it with a less Socratic eye, it has Cabernet Sauvignon's fruit expression with Grenache's easy, open feel. In other words, almost the exact opposite of the initial goal. You can try for it yourself, because it has been imported into the U.S. for a couple of years now, and it makes good wine.
A New Red for Your Glass
Since Marselan didn't turn out the way growers had wanted, nothing really happened with the vine commercially. Marselan has been grown in the Languedoc ever since it was first crossed, and over the course of four decades, some estates made single-variety Marselan with leftover fruit, but these weren't made for commercial release. In 2002, Domaine Devereux made the first one I'd ever seen (a gift from a friend from France), and it was pretty good. Château Camplazens 2006 Marselan is widely available and delicious, if a little too polished (it strikes me as having an 'international' character, and is therefore less distinctive), but the Domaine de Couron 2006 Marselan is first rate, with brilliant black fruit and a pure, unfettered expression. The one I found most interesting, however, was a blended wine from Domaine de la Mordorée, the great southern Rhône Valley producer: 2007 Re:NAISSANCE, which was fifty-fifty Merlot and Marselan. The soft-core luxury of Merlot gave the Marselan a velvety richness that prompted me to buy another bottle. I would've bought a case of this one, but I was in Paris, and schlepping that across the Atlantic wasn't my idea of fun. Yeah, the Mordorée was good...but not that good.

I've been drinking a fairly old wine this evening--middle-aged would be a better description, as it is but 14 years old, in its prime, and not likely to improve further: the Château de Beaucastel 1996 Châteauneuf-du-Pape. It is really quite beautiful, and as this wine is unlike most Chateauneuf-du-Pape anyway (it is mostly Mourvèdre while the preponderance of Chateauneuf is principally Grenache), its silken expression is not entirely a surprise. It has a lovely and much lighter texture than it did when it was young, but that is not uncommon with mature wine. The aromas and flavors have clarified themselves over the years, simplifying the experience of the wine while showcasing and magnifying its complexities. It has become an open transmitter of the growing season and the efforts of the people making the wine. This wine has entered a fascinating phase: there are some notions that swirl in and out of the overall picture of the wine, while other elements--expressly the gossamer luxury of its red fruit qualities--are constants. Its character is volatile (though not scary volatile) and exuberant, yet mature and graceful. Think Cuba Gooding Jr. as he ages--that'd be this wine. 
In the Loire Valley, the appellations are mostly dispersed along the banks of the Loire River, and some of its tributaries. There are a few curious regions that are generally included under the administrative umbrella of the Loire Valley that have about as much in common with the Loire as a cygnet does with ducklings. In fact, I have heard some Loire Valley producers refer to one of these regions in particular, Châteaumeillant, as the ugly duckling of the Loire.
Wine, even basic-yet-tasty wine, really fascinates me. This is why I loathe the 100-point scale for assessing wine. Scoring wines in this way is…you know, I can’t actually say what I’m thinking, because I want this to remain a family-friendly site.... Okay, how's this: giving wine a numeric score is the crowning achievement of the boundless limits of superficiality. Before someone raises the alarm and I have to start stuttering and backpedaling, I should say that those who engage in this practice are not themselves superficial (to my knowledge). My issue is that, even if you read the tasting note (which is supposed to illuminate the score), grading a wine so specifically is a perfunctory way of taking stock. Sounds like a paradox, I know, considering that spending the time and mental energy to award a score ought to allow you to get lots out of the wine, but it fails to take contextual usage into account. Does anyone--other than a wine critic--drink wine with a mind to a hierarchical score? Even wine critics (well, most of them, anyway) don't do this for pleasure. I can tell you what we (since I suppose I’m one, too) do is compartmentalize: we taste through a whole lineup of wines as a part of the job, little sips and sniffs at a time, no food, except for the occasional piece of bread or a cracker. For good old fashioned joy, however, we just pop the cork and go. Wine is (and has always been) meant for that much nobler pursuit.
