Your age is "too young" for any problem with a little coffee/caffeine - but we all have a limit. Sounds like you know one thing to avoid. I doubt that one beer should cause any problem, unless you "never drink", so any alcohol is a shock to your system.
Stay off the caffeine and see what happens. If the high HR continues it may be best to consult a cardiologist.
im 42 y.o male, had the same problem a few years ago,(at least 4 years) i noticed my heart raced after a coffee,so i decided to simply stop eating or drinking anything with caffeine, almost instantly my health returned to normal.i also get a racy heart(the day after ) a drinking binge.im seeing a doc at the momment about this, as the last time i got drunk 3 months ago ive had and still have on/off palpitations.first time its gone this long.possible next stop cardiologist.
I have this exact same problem ... If I have 1 beer or any stimulant my heart rate goes to about 120bpm for hours ... If you ever find out can you let me know?

I get this with cigarettes only, I do not know about alcohol. Ive smoked cigarettes where I didnt get it, but I stopped, Its just to scary.
Sounds like a thyroid problem to me
I've had similar problems - sensitivity to caffeine and now, to alcohol. I take no medications and lead a healthy lifestyle. I avoid wheat products and that helps a lot. Check this out:https://www.caffeineinformer.com/caffeine-sensitivity
It could be genetic, an immune response, or related to liver enzymes. I bet it's all the crap in the food chain an environment that we didn't have decades ago.
