Your Guide to Organic, Biodynamic and Natural Wine


Domaine Bio Coste Biau ‘06

While in Saumur for this year’s Dive Bouteille, I found myself dining at Bistrot Les Tontons, a cozy, good-vibe place with plenty of local natural wines. Gerald Beaumont, Tonton’s owner, kindly introduced us to fellow diner Mathieu Coste, vigneron of Domaine Bio Coste in the Coteaux du Giennois, north of Sancerre.

We hit it off immediately, and with Mathieu desperately wanting to practice his English, and I my French, we managed to have a long conversation about his natural winemaking practices. Then, much to my delight, he presented four of his wines for tasting, one of them being the Biau ’06. Biau, he explained, is the local vernacular for “beautiful” (as well as a play on “bio”) and it’s accurately named. The cepage is 80% Gamay to 20% Pinot Noir. The minerality, which he calls his acidity, is stunning. The aroma is mushrooms and moist earth, and then comes the spice and brilliant fruit on the palate.

While it’s ready to be enjoyed now, he thinks it can go another ten years. The 2006 is his current vintage, a testament to his patience in the winery. The cost is a slight splurge, probably around $25, but well worth the experience.

And speaking of experiences, while in the Loire we also managed to swing by La Levee de la Loire, a small, superb, all-natural, all-Loire Valley wine tasting held in Angers. I’ve never tasted a more uniformly amazing assemblage of wines, many available here, and others looking for a home here in U.S. If you haven’t already, get yourself to your favorite natural wine shop and check out their Loire selections. They’re hard to beat for their diversity, their elegance, their compatibility with every cuisine, or even just as a great vin de soif.
