i saw an old post where you came up with a gravity reading of 40 (1.04) for pure watermelon juice...
here's where i'm confused: that's 40 points per pound per gallon, right?
so if I use 4 cups, which should be about 2lbs of watermelon juice (working off the fact that a gallon of milk weighs 9 lbs, so a quart should weigh about 2 lbs... and yes, I know that milk is not equal to watermelon juice), that's about 80 points, divided by 5 gallons = 16 points of gravity? that is not insignificant...
is my math bad? (it very well may be...)
