Making Juice and Cider

I've been making juices this year with no sugar or other sweetener as i"m now pre-diabetic. Gooseberry and crabapple are quite good the different juices I have made with blackberries are not as good as with sugar. I haven't given up though. I still have elderberries to harvest although they are been ruined by birds and I still plan to make grape juice when my grapes are ready. I made excellent cider last week using Duchess apples and Whitney crabapples which previously I had let all rot.
