If grapes could talk, they'd recount their dreams, the first time they got plucked, and the first time they felt victimized by nature's rumor mill—the vine. Taste the tales of the grape with today's Groupon: for $27, you get a two-day wine-tasting passport ticket to the 21st annual Roll Out the Barrels weekend in San Luis Obispo (a $55 value).

At Roll Out the Barrels, more than 20 San Luis Obispo wineries uncork their aromatic ambrosias in a bacchanal of cultivated events and self-guided tours. Bopping across a backdrop of rolling grapevine-enveloped valleys, passport holders visit their choice of vintners in a self-guided tour, exploring wineries including Claiborne & Churchill, Per Bacco Cellars, and Salisbury Vineyards while reaping benefits such as complimentary wine tastings, special discounts on purchased spirits, and tattoos of favorite grape varietals. After checking in at the Baileyana Winery, Groupon holders raise a commemorative wine glass for a series of reserve barrel tastings, let palates alight on a panoply of savory food pairings, or succor other senses with entertainments spanning from live music and local art to wine discussions and chair massages. Events unfold on Saturday and Sunday.
