I used to think there were a few dozen grapes used to make wine — the usual suspects that you typically see on a wine list like cabernet sauvignon, pinot noir, and chardonnay. Suffice to say...I was a bit off. There are over 1,000 different grapes that are commercially used to make wine. Just in Italy alone, there are hundreds of grapes I'd never heard of before — names like Rondinella, Grechetto, and Pignolo. That means there are a whooole lotta wines to try out there.
