As a regular coffee drinker, I didn’t personally experience the advertised boost in energy or focus, so the effects were unfortunately negligible for me. Additionally, I found the mint to be overly sweet—likely too much so for many European palates. For the EU market in particular, I would recommend adjusting the flavor profile to align more closely with the subtler, more refined taste of Italian or French mints already available.
It is a great effort, and I wish more success!
