Fruit Sugar – Fructose Powder
Fructose is sugar derived from fruits and plants. We use fructose to make an indigo fermentation vat that does not require lye or chemical reducing agents such as thiourea dioxide or sodium hydrosulfite.
This is a food grade product that looks like fine sugar and is used as a reducing agent, and yes, it is sweet but we don’t recommend using it in your coffee! You will be delighted how simple and easy it is to make an indigo vat using fructose. Previous fermentation recipes often took a number of days but this is a quick and easy method.
