Elderberry Juice

I've used all my elderberries to make juice and I only trapped one adolescent robin in the process (it was fine once I untangled it from the net protecting my berries). Besides robins, sparrows were eating my elderberries. I don't care for elderberry juice by itself: one batch was mixed with crabapple, one with several other sour berries and the best batch which I made the most recently was mixed with grape. I'm still planning to make grape juice- there are not quite ripe yet even though we've already had a frost.
