Best after-holiday-meal drink: Nocino della Cristina Napa Valley Walnut Liqueur

This stuff is awesome. You may read "walnut liqueur" and think "Ewwww," but it's exceptionally well-balanced. Not too sweet, not too nutty, not too cloying: it's like a yummy nutty holiday in a glass. Drink it neat, like a digestif. You could also use it for cocktails, but hey, if it's good enough to drink all by itself...

Retails for around $30 for a 375ml bottle.
