The Barrel Room has paired down its food program, making wines by the glass and retail sales its stock in trade these days rather than a menu. But this is a great place to explore the mysteries and pleasures of wine, especially via wine flights (three ample pours in the $15 to $25 range). The wines are not inexpensive here. You can find a glass of Pinot Gris or Sauvignon Blanc for $12 or $13, but reds start at $14, and a higher-end Pinot Noir, Zin, or Cab are $18 to $28. But the choices are fascinating, and relative bargains can be found if you work the flights of Zinfandels, California Pinot Noirs, Cabernets, pre-Prohibition “lost” classics, “Rhone Rangers,” varietals from Oregon, Washington, and the East Coast. We recently were well pleased with a 2010 German Riesling, a 2011 Croatian red, and a 2012 Saint-Joseph in stock from a previous French focus. Here’s hoping the platter of house-made charcuterie makes the cut. Open 3 p.m. until late daily.
