Thanks to cartoons, many Americans believe that the correct way to taste wine is to take a sip, then witness something so shocking that it causes them to involuntarily expectorate. Skip the spit takes and sample wine correctly with today's Groupon: for $49, you get a tour of five wineries, wine tasting, lunch, and a wine glass from The Wine Line (a $104.95 total value) in Paso Robles Wine Country. Enabling odysseys to Paso Robles's plum-shucking boozeries, The Wine Line offers patrons biodiesel-fueled, "hop on, hop off" shuttle service (a $59.95 value) that allows travelers to create their own itinerary and guzzle spirits at their own leisure. The Wine Line's five-stop tour equips guests with an organic gourmet box lunch (a $15 value) and a wine glass (a $5 value) to sample wines at all five stops (a $25 value). Tour-goers can ladle splashes of old-vine Estate zinfandel and Black Monukka dessert wine at Rotta Vineyard and Winery, or capture taster-tickling vinos of sangivoese and cabernet at Hunt Cellars. This Groupon also includes stops at Castoro Cellars, Doce Robles Winery & Vineyard, and Donati Family Vineyard.
