Background

This experiment is a test to see how the enzymes from malt and koji combine to make a hybrid amazake. Traditional amazake made with koji produces glucose, a sugar that is about two-thirds as sweet as sucrose (table sugar). Malt, on the other hand, primarily produces maltose, which is only about one-third as sweet as sucrose. By combining these two, the goal is to create an amazake that has a malty flavor but is significantly less sweet than a traditional version, potentially making it more palatable and versatile in non-alcoholic drinks.
