Talk about a rule that's hard to break!

It turns out that chemistry dictates that the strongest possible distilled alcohol is 95.57%: https://gizmodo.com/why-cant-you-make-liquor-thats-100-percent-pure-alcohol-1701953611

I have tried a 95% alcohol, an Polish drink called "spiritus" that was smuggled into the US because it's illegally strong.

Oh, boy.

I would call it "not pleasant" even though it was quite pure - just the taste of 95% alcohol is hard to swallow.
