Yes, you can entertain and impress with wines under $20. Three prime examples: at $19.50, the Blasted Church sauvignon blanc is sharp and herbaceous and packs a lingering punch of acidity due to a late harvest in October 2012. The M. Chapoutier Côtes du Roussillon Domaine de Bila Haut Blanc 2012 is $15.99, and startling, how great it is, at this price. Finally, just under the wire, a full-bodied, structured, and easy to love M. Chapoutier Côtes du Rhône Belleruche Rouge 2012, $17.99.
