Being a black coffee drinker, flavored coffees have never been my thing but my wife and daughter like them. They go well with cream and sugar (if the don’t already have it) and seem appropriate especially around the holidays.
I do remember that I used to like Mexican Coffee with Kahlua and sometimes a shot of rum or tequila. That was a long time ago but it was good so maybe flavored coffees have a place.
Enjoy your flavors!
