One of those shops you just want to root for, this Capitol Hill “wine boutique” is a D.C. institution. Co-owners Michael and Michelle Lim Warner launched the business simply based on their shared love of wine, and DCanter offers a wide selection of bottles, as well as a slate of classes and events held at the onsite tasting room. VinePair readers agree the classes are a big draw; subjects span such entry-level pursuits as Taste Fundamentals, as well as finger-on-the-pulse topics like Exploring Cru Beaujolais.
