I just back sweetened a 5 gallon back of Tart Cherry Melomel and I did it with sweet cherry puree. Little at a time but I added 4 cups of the puree and it tasted amazing. I also used potassium sorbate and Camden Tablets in it prior to doing such. Normally I back sweeten with honey mixed with a little warm water but with this batch I really wanted the cherry notes to be prominent.
