Filter might get obliterated by the Tonic, you probably need the concentration of espresso. I tried the espresso tonic thing, didn’t really get it, but then I’ve never really got any cold coffee drinks.
I didn’t really either till I made iced pourover. Eg 40% of your water is ice and 60% is boiling water. Really enjoy that. But then, it’s hot where I am and iced coffee is very much appreciated.
I've found it is super dependent on getting the right tonic. Can be good, can be real grim 😅 but I'll drink iced filter all year, over most other drinks, so I'm the other end of the temp scale!
I’ve gotten quite into drink espresso, (gin) and tonic - anyone tried this and would filter work as well?
