Most fruit grows jealous of the attention grapes receive when being made into wine, which is why lemons are so sour and falling apples always aim for the heads of scientists. Learn why Newton's discovery was a crime of passion with today's Groupon: for $10, you get a wine tasting for two with cheese and hors d'oeuvres at Spirits of Madeira (a $20 value). Tastings are held Tuesdays from 5 p.m. until 7:30 p.m.

For more than 19 years, Spirits of Madeira has been the toast of area wine cellars, filling glasses with savory arrays of wines from all over the globe. Seasoned sippers conduct each 2.5-hour tasting, expanding palates with the careful matchmaking of two red and two white wines accompanied by select cheeses. While paired spouses, friends, and former field-trip-bus buddies compare sauvignon blancs and other wines from various grape-growing regions, the knowledgeable staff will field questions and provide interesting wine tidbits so patrons can impress guests at dinner parties and one-up the food samplers in local grocery stores.
