There are literally hundreds of wine grapes, but to get a really strong start in understanding quality wine, get familiar with what I call “the big six” wine grapes: Riesling, Sauvignon Blanc, Chardonnay for whites; and Pinot Noir, Merlot/Cabernet (which are very similar and often blended together), and Syrah aka Shiraz for reds. Learning the taste profile and body style of these is easy, and will give you a huge leg up when navigating the wine list or a wine shop.
