This newish wine bar is riding the wave of Casco sophistication, attracting an upscale crowd of wine drinkers. It's always mellow here.  The interior has a semi-industrial vibe, with exposed air ducts and a crafty bar area designed from wooden wine crates. Cozy couches make it feel more lounge-like. The lists of wines by the glass and by the bottle are extensive, and the vintages pair well with the house's Italian-inflected tapas. The bar hosts frequent tastings, both promotional and educational, and there is live music on occasion.
