After living in the Finger Lakes region for five years, I have become a wine enthusiast. In 2008, I took a selective class "Introduction to Wines" while studying at Cornell University, which covers major wine-producing regions of the world, identifying labels and aromas, food and wine pairing, and wine tasting etiquette.
After taking the class, I might have escalated myself to be a wine snob! Seriously, I appreciate all wine varieties and the cultures influenced by the wine-producing regions.
Some argue that there are "rules" to food and wine pairing like Pinot Noir great with pizza and earthy-flavored dishes, chardonnay with fish and seafood, Riesling with spicy Asian dishes. It's really a personal choice.
