I saw a question on here about cold brew vs hot brew caffeine content and was wondering what is the easiest (or best) way to measure this at home (if possible)

If you can find Ethyl Acetate (some nail polish removers), you can probably do this.

I don't think anything short of HPLC or extraction and purification will give you a precise result. If you'd be ok with more of a rough idea of whether something has a lot or a little caffeine, there are test strips available.
