Learning to discern the tastes of different wines is a valuable social skill, much like dancing or remembering the names of people's imaginary friends. Expand social acumen with today's Groupon: for $25, you get a two-hour wine class at Cardinal Hollow Winery in North Wales (a $50 value).

Cardinal Hollow Winery's two-hour Wine Education class demystifies wine through a tour of its facilities, a tasting, and a lesson on the history and process of winemaking. Follow the tumultuous journey of winemaking from growing and harvesting grapes to crushing them and trapping their juices in barrels, before releasing the sweet, fermented nectars to the masses. Equip palates with discerning taste buds in a casual sipping session, and pocket the tasting glass as a complimentary souvenir. Libations are balanced by a spread of snacks and sturdy table legs, as sippers absorb lessons on wine and food pairings.
