Yeah that sounds about right lol. Any time I hear someone say “you can’t ferment x and have it be drinkable” I go out of my way to try and ferment it. I heard that about watermelon and the watermelon wine I made turned out great, and distilling it to moonshine made the best watermelon brandy I’ve ever had (every commercial one I tried has the artificial watermelon taste). I’ve also made milk wine. Maybe I am a mad scientist…
