One year at Christmas, my dear hubby was given a bottle of coffee liqueur. I don't remember the brand name though I don't think it was Kahlua. Anyway, it was something DH did not want so he gave it to me. That bottle probably lasted at least 10 years.
I liked to put a little in my hot chocolate every now and then. I have really been missing it lately so I looked to see if I could find a recipe.
