Although Congress recently passed a bill outlawing wine consumption, the attachment of a last-minute rider allows cyclists to legally imbibe. Pedal your way through loopholes with today's Groupon: for $44, you get a winery bike tour (an $89 value) from East Bay Winery Bike Tours in Oakland.

Starting at the Ferry Terminal in Jack London Square, oenophiles embark on a 10- to 14-mile bike trip to sample the East Bay's finest grapey fare. The cost of the tour, which runs from 11:30 a.m. to 5 p.m., includes your two-wheeled velocipede and a helmet, as well as the opportunity to sample tasty potables poured out at each stop by the vintners themselves. An experienced, enthusiastic winologist will lead you over flat, scenic pathways (urban and country alike) in search of three or four boutique wineries, where grapes are both scientifically and magically transformed into wine. The tour will stop for a picnic lunch along the way (included with this Groupon), and any bottles you purchase during the excursion will be portered by the guide. Tours end with a short ferry ride back to Jack London Square.

Unlike cars or sentient Segways, bicycles are excellent vehicles for wine tours because they amble along at safer speeds and never lead mecha rebellions. Saddle up the perfect tourmobile and enjoy a peaceful ride through wine country.

Participants must be 21 years of age or older.
