Instructions: 1. Pour frozen juice concentrate into a 2-quart pitcher. Refill the can from the concentrate 4 times with club soda (48 ounces, or 6 cups of club soda) and pour into the pitcher. Stir. Serve cold and enjoy your delicious sparkling juice! Homemade Sparkling Grape Juice Additional Notes: For a stronger juice with less carbonation, add only 3 cans (36 ounces) of club soda instead of 4 (48 ounces). We like to use grape juice or apple juice, to make sparkling grape juice or sparkling cider. Any frozen juice concentrate will work, although orange juice is probably our least favorite of the ones we've tried so far. :) Homemade Sparkling Grape Juice See my blog post about this sparkling juice for a price breakdown and comparison to store-bought sparkling juice! Preparation Time: 5 minutes Tammy's Review: This homemade sparkling juice tastes JUST like the bottles of sparkling juice that are sold for at least $2-3 for 750ml (about 25 ounces)! I love that we can make our own for a fraction of the price... plus get 100% juice (and carbonation of course)! :)
