A shot of whiskey, rum, or brandy can go good in a cup of coffee.
Coffee also goes pretty good in a porter or a stout, but the coffee is usually added to the beer during fermentation...
I've never tried it before, but now that I'm thinking about it, a shot of espresso in a cup of eggnog would probably be pretty good. Call it a White out, white eye, red nose, a rudolph...
being a bartender for way too long i have a few that work well with coffee. Theres the usual suspects, Irish(Jameson whiskey),highland(scotch),jamican(dark rum),french(brandy) justto name a few. All can be made with a double espresso topped with hot water but work well from a press too. Just add brown sugar to sweeten and float some cream(whipped then add pouring cream) to finish. For a pre dinner drink its gotta be the espresso martini. 16oz martini glass with sugar rim,double espresso,vanilla vodka and kahlua.Shaken and strained...but it does pack a bit of a kick and will probably keep you up all night
btw a standard shot of alcohol is 35.5ml
I'm tolerant of Baileys and loathe Kahlua. There's a vodka company called Van Gogh that has, or at least used to have (Havent been able to find it in a while), an espresso flavored vodka. For a guy that generally doesn't like flavored liquors, I liked this particular espresso vodka. They also have some off the wall flavors like PB&J and, iirc, some spicy pepper vodka. If I don't have to go to work later that day or if I just came home, sometimes I'll put a shot (or two or four) in my coffee. Generally, though, it's either straight coffee or straight liquor
I agree with Bob_E. Although I don't drink very often, a little whiskey/scotch in my cup of coffee gives it a nice kick. I don't mean cheap scotch either! Lol. A decent priced, aged scotch/whiskey is good. I just recently tried Sheep Dip (aged 10-14 years I believe) from BevMo. It's not too bad alone or with coffee.
You can choose Frangelico for the nutty flavor. Kahlua can be a good partner for coffee because it adds sweetness and extra bit of roasted flavor. Drinking Amaretto having almond flavor which is subtle can be defuse if you have strong coffee.
