The only thing we remove is the herb residues, just as you remove the tea leaves when the teen has pulled. In Feel Great, however, the herbs do not only give taste, but rather act as food for the lactic acid bacteria, which in the process converts parts of the herbal substances to fermented herbal extract.
The lactic acid bacteria form organic acids which lower the pH, and this naturally preserves the product because the bacteria that normally cause decay cannot live at such a low pH. In this process, the lactic acid bacteria eat 100% of the added molasses, so that the product is ultimately sugar-free.
