For us, Claudie Riffault's Sancerres are some of the best out there. He's not as famous as the likes of Francois Cotat, but the wines are of similar quality (and a little cheaper!)
Smoky, complex, stony and minerally, like no other Sancerre you'll likely have tried.
Grape variety: Sauvignon Blanc
Winemaking method: Organic
