I was never a big holiday cheer person — until I moved to New York. Something about this hot mess of a city all lit up and covered in snow is enough to melt even my scrooge heart. And while I’ll admit it’s a little early to start stringing up the spangly lights, I’m going to say holiday cocktails are fair game. Cointreau is teaming up with the Botanist Gin and Mount Gay Rum to get the season off to a gleeful start with their Art of the Mix Studio cocktail classes, held at various times on Wednesday, Thursday and Friday at Milk Studios. For $20, you’ll learn to craft three beverages sure to make you the star of the holiday party circuit, with the added bonus of feeling like a downright angel while doing so: All proceeds from your ticket go to Oceana’s ocean restoration efforts.
