Italy's white wines are as diverse as the country's reds. There is an Italian white wine with a trove of native varieties to fit every budget and occasion. Unfortunately, there are so many choices that shopping for Italian white wine can be overwhelming. It doesn't help matters that many of the white grapes have similar-looking names. However, you don't have to memorize an encyclopedia to find the perfect wine for dinner. Knowing a few essential wines will ease the confusion and simplify the shopping trip (hint, if the grape or wine name has a "v" in it, you will probably love it.)
