Would like to use 4# per gallon. The melomel is a great idea as well. My next batch of wine I plan on doing a 5 gallon blackberry melomel. About 9 mo ago I did a 1 gallon of the blackberry. I just bottled it. At bottling it tasted wonderful. Can't wait to fast it in a year or so! Should turn into gold by then. That's why I am doing another 5 gallons.
