There’s the kind of wine store where you blindly grab a bottle of whatever’s featured on the end aisle, and then there’s the Urban Grape, where you can actually try 16 wines before you buy them. Browsing is a breeze, thanks to an intuitive shelving system based not on varietal or region, but the body of the wine. And there are cool customer perks: The Chestnut Hill and South End stores both accommodate special orders and private tastings, and they offer delivery, gift baskets, sampler packs and win­­­­e cellar consultations with co-owner TJ Douglas.
