Grape juice magically transforms into wine in the same way milk becomes cheese and a 1972 Dodge Dart becomes an even older 1972 Dodge Dart. Tipple the tasty transformation with today's Groupon: For $10, you get a VIP wine tour, tasting, and food-pairing demonstration at Sand Castle Winery (a $20 value) located in Erwinna. Founded by Slovakian wine makers in the '80s, Sand Castle Winery makes all its wines from 100% vinifera grapes planted in the bountiful Delaware River region, with a 7,000-square-foot wine cellar and castle that overlooks its fermented dominion. This deal gets you an extensive two-hour tour of Sand Castle Winery's facility and vineyards, where you'll get to sample the palate-pleasing wines; enjoy food pairings such as cheeses, herbs, and chocolates; and explore the castle with its 15-mile views, 30-feet underground wine cellar, and Silvan Elves manning the north tower with bows at the ready. Tours are led by Joseph Maxian and other Sandcastle winemakers, who use insightful information with a dash of wit to elucidate how their grapes become wines, including the subtly sweet 2005 Johannisberg Riesling and the strawberry-tinged 2007 Pinot Noir.
