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 $20 worth of locally grown wine at Grinder's Switch Winery in Centerville. Today's deal is not valid for the sangiovese wine or online orders.

Grinder's Switch Winery sits atop a 110-acre estate flourishing with vineyards that produce a variety of palate-pleasing wines. Inside a hand-built log cabin set against a backdrop of efflorescent countryside, Grinder's tasting room welcomes sophisticated sippers to sample such wizened grape juices as the 2009 Pearl—a sweet wine derived from niagara grapes ($10.93)—and the Blondy ($12.75), which boasts aromatic scents of apricot and peach. Swirling fragrances of golden apple tickle the noses of Honeysuckle Rose ($13.67) drinkers, while the lightly-oaked 2009 chardonnay ($13.67) proffers a finish as crisp as dollar bills made out of Granny Smith apples.
