Actual moonshine, meaning made in the hills under the moonlight, is illegal because the TAXES have not been paid on it.
To get an idea what it tastes like, stick an acetylene torch in your mouth. About the same sensation!
You can purchase "151" or "everclear" which are legal moonshines. See above for taste.
80 proof is about right for me....as in a good scotch, or some Jamesons on ice, or a belt of Tanqueray on ice.
