In a proper tasting, wine must be held up to the light to gauge its color, tossed on a cat's back to judge its acidity, and sipped through a crazy straw to annoy the host. Become the toast of any tasting with today's Groupon: for $52, you get a private, in-home wine tasting for 12 people from PRP Wine International (a $200 value). This Groupon is not valid in the Upper Peninsula.

Stocking its shelves with top-quality wines from around the world, PRP Wine International labors to spread the culture of wine to novice oenophiles and practiced imbibers alike. Expand your grapey knowledge in the comfort of your own home or tree fort with tips from wine-wise consultants. Fete throwers may suggest wine preferences in advance of the fermentation celebration, where five different bottles of red and white vino will be sampled among friends, neighbors, and chatty coffee tables. PRP Wine International strives to use wine as a building block for improving relationships with its clients and increasing the quality of their lives while educating bottle and cork collectors on the purported healthy benefits of wine imbibery.
