What do you do with a freezer full of elderberries?

On the farm we have a excessive amounts of elderberry bushes. Last year all of them were harvested, put in the freezer and then forgotten about. Last week we took half of the frozen berries out and pressed them to make elderberry juice concentrate. We mixed some of it with maple syrup and ate it with crepes- so delicious! I’m thinking about fermenting the rest and making wine.
