Rejuvelac is a raw food made by sprouting a grain, soaking the sprouted grain in water for about two days at room temperature, and then reserving the liquid. A second batch can be made from the same sprouts, this time requiring only about one day to ferment. A third batch is possible but the flavor may be disagreeable. The spent sprouted grains are usually discarded.
