I will forever associate the Summer of 2011 with my life-enhancing discovery of the Negroni. Before discovering this superb cocktail, I cast about trying newfangled cocktails indiscriminately. As much as I love the Negroni, at its essence, it's a summer drink. I'm looking for recommendations on a fall/winter cocktail to replace the Negroni until next Spring. I favor gin as my spirit, but I'm open to non-gin-based cocktails as well, as long as they're not too sweet.
