Everything I read on research into watermelon wine or brandy people mentioned to not bother and that it never turns out. Decided to buy and blend 6 watermelons and give it a shot anyways. I must say, my apple pie brandy was my go to crowd pleaser, but this? This easily overtook it! (Aside from the 3 hours of cutting watermelons, that was a pain)
As a person who tried a friend's watermelon wine and helped them pour it all down the drain that some day, I'm glad your melon experience went well.
Yep, I think the key is to not boil it. Besides that, if it tastes like cucumber, backsweetening it makes it taste like watermelon again.
