Since many of you seemed to score high marks on my first grape quiz, I thought I'd test you with another round. I'll start by testing you on the most elemental classification: whether these up-and-coming varieties are red or white grapes. Is your best guess really that educated? You'll know when you keep reading.
Not so long ago, well-known grapes like Chardonnay, Merlot, and Cabernet Sauvignon were the only varietals that could be found in wine stores and cellars across the country. Not today: from Viognier to Fumé Blanc, grocery stores have been flooded with lesser-known grape varieties that are slowly yet surely rising to prominence.
