Energize and rehydrate without caffeine. Simply add water to make small servings or up to six gallons with the 1 gal concentrate. Or you can use the 3 gal bag in a box to make up to 18 gallons when you have larger groups like sports teams or athletic events. The carbohydrates and electrolytes stimulate rapid fluid absorption, quickly replacing the fluids and electrolytes lost in sweat. Cool, satisfying taste.
