This Haymaker's Punch is the healthy way to rehydrate.
Stir everything except ginger (& optional blueberries) together in a large pitcher and mix very well. Slowly pour liquid mixture into 16-oz glass bottles with wire and ball stoppers. Add about 1 Tablespoon grated ginger into each bottle (add 1 Tablespoon blueberries if desired) and fasten the lids.
