Talk:Mulberry Wine

I had a couple questions about making mullbery wine. You mentioned that mulberries lack body, what if one paired them with blackberries, fresh or the juice? how would that change the recipe? I don't care for grape juice, I think its way too sweet, which may be why you choose it because the yeast needs sugar, but how would one know how much sugar to add to substitute some other fruit or juice? And how much wine does this make? Sorry, I'm a first timer. I've been interested in this for a while, and have a ton of mulberries in my backyard right now....
