Beer-brewing garners its devotees the gift of discipline as well as a keen eye for discerning fermentation vats from extra-large beer steins. Brew boldly with today’s Groupon: for $65, you get up to six cases of freshly brewed K & B Light beer at Keg & Barrel Custom Beer and Wine in Tecumseh (a $130 value).

Keg & Barrel's suds emporium empowers brew enthusiasts to concoct a personal bounty of hop and wheat wonders. Customers emblazon their signatures onto the brew DNA of K & B Light beer—a golden lager flavoured with natural grain and hops—by adding specified yeast to the mix, then leaving the fermentation process to the K & B staff and its specially trained grain gremlins. After gestating for two weeks, the brew is ready to come of age and can be either bottled or canned. Suds enthusiasts can bring in their own clean bottles, opt to purchase K & B’s glass or plastic varieties ($56), master the dark art of self-canning with the on-site canning machines ($41), or haul it all home in a rented keg ($50 deposit; $40 refund on return). Thrifty thirsters may sample their freshly bubbled earnings upon readiness, or guard their stock until the national currency is finally based on the amber standard.
