Like water balloons, grapes are spherical, come in a variety of colors, and make a bigger impact when filled with juice. Raise a glass to juice's grown-up counterpart with today’s Groupon: for $10, you get one admission ticket to the 11th Annual North Carolina Wine Festival on May 28 from 12 p.m. until 6:30 p.m. at Tanglewood Park in Clemmons (a $20 value for advanced purchase, or a $25 value at the door). Your Groupon discount applies toward the cost of admission to the festival.

Maturing ever closer to perfection in its second decade, the North Carolina Wine Festival convenes a statewide celebration in honor of the fruits of vineyard labor. Upon entering Tanglewood Park's verdant grounds, taste testers get commemorative wineglasses before scratching their oenophilic itches with varietal samples from vendors including Chatham Hill Winery and Hutton Vineyards. Nearly 40 wineries splash out tastes of their red and white magnum opuses, filling mouths with tasty drams and minds with a flurry of mellifluous wine terminology. After the tastings, palate-pleasing wines can be purchased by the glass for festival sipping, or in bottles and cases for at-home drinking or assembly of backyard temples to Dionysus.

Live performances by The Band of Oz, Chairmen of the Board, and The Plaids distract ears from taste-bud envy, and dozens of exhibition booths dazzle eyeballs with a mélange of arts and crafts. Food vendors pepper the park, dishing up both solid sustenance and nonalcoholic beverages. Parking is free, and the festival runs come rain, shine, or the surprise reinstatement of Prohibition.
