It has been way too many years to remember the exact recipe for the watermelon wine, but it was from a basic wine recipe, using watermelon instead of grapes. We made several batches - the first batch wasn't very good. Extremely sweet and little other taste. The second batch was made with mainly watermelon, and very little water, using a higher alcohol yeast, but still really sweet. We ended up using green teabags, about 6 watermelons, a couple of gallons of water, sugar, and low alcohol yeast, after the primary fermentation was done, we racked it for about a month, strained, added some more watermelon, a little honey and high alcohol yeast. This fermented for about a month, (we alternated adding sugar and watermelon every time the fermentation seemed to stop). We racked it once, for 2 or 3 months, drank about 1/2 of it (it was good OK?),then bottled the rest. About a month later bottles started popping the corks (oops - forgot to add the camden tablets), so we had some sparkling watermelon wine, which was interesting.
