Invert sugar is much more commonly fermentable than sucrose and has a tendency to be darker in coloration. But, its two lowering sugars stop the oxidation of other substances.
The syrup is ready in this way when fluid extracts, tinctures, or other liquids should be additional.
Among the many very good suspending agents is bentonite.
