It happens, even to the best of us: after taking a chance on an unfamiliar vintage, we've left a restaurant disappointed. Or perhaps we've returned from the wine shop only to read a less-than-stellar online review of our purchase. In the quest to make wine buying easy, accurate and fun,\u00a0Wine Enthusiast Magazine has just released an iPhone buying guide application (available at all Apple stores) for on-the-spot expert wine purchasing advice. Functioning as a virtual sommelier, the $9.99 application compiles all the reviews from Wine Enthusiast Magazine's extensive database into an easy-to-navigate format; users can search via appellation, price, variety or wine rating. There's also a glossary with over 1,400 wine terms, reference sections on serving, cellaring, ordering and food pairing and\u2014highly appreciated by wine geeks\u2014a vintage chart with information on per-year quality for varieties from all over the world. "Our new iPhone application for Wine Enthusiast Magazine takes the risk out of wine buying, " says Adam Strum, CEO of Wine Enthusiast Companies.
