1 (.25 ounce) package active dry yeast
4 cups sugar1 (12 fluid ounce) can frozen juice concentrate - any flavor except citrus, thawed
3 1/2 quarts cold water, or as needed
1.Combine the yeast, sugar and juice concentrate in a gallon jug. Fill the jug the rest of the way with cold water. Rinse out a large balloon, and fit it over the opening of the jug. Secure the balloon with a rubber band.
2.Place jug in a cool dark place. Within a day you will notice the balloon starting to expand. As the sugar turns to alcohol the gasses released will fill up the balloon. When the balloon is deflated back to size the wine is ready to drink. It takes about 6 weeks total.
