Wines, like a comfortable T-shirt or a hard candy left to ripen under the couch, only get better with age. Taste the passing of time with today's Groupon: for $10, you get a wine tasting for two (a $20 value) and 15% off purchases of select bottles at Wente Vineyards in Livermore Valley, valid during public wine tastings in either the Estate or Vineyard Tasting Rooms.

Vinifying for more than 125 years, Wente Vineyards is one of the oldest continuously operated wineries in the United States, currently operated by the fourth and fifth generations of the Wente family. During public wine flights, seasoned oenophiles and tenderfooted sippers alike can taste a rotating selection of five wines. Samples could include tonsil-ticklers such as the crisp and fruity Louis Mel sauvignon blanc or the dark and rich Southern Hills cabernet sauvignon, which is smoother and more alluring than a dolphin at a masked ball.

Afterward, Wente Vineyards will offer current vintage wines from the vineyard selection and heritage block for purchase, with a 15% discount. A registered California historical landmark, the winery boasts a restaurant and golf course, in addition to its 3,000 acres of sustainably farmed vineyards, allowing visitors to get their fill of drinking, eating, and aiming golf balls at grape-stealing bandits.
