Conversion of ginger starch

[IkiMano]

Hello I am interested in making ginger beer. I happen to have a abundance of ginger and starch from ginger. Ginger starch is very similar to corn starch in apperance. I would like to convert the starch into sugar to ferment. What is the simplest way to to do this?

I know this post was 5 years ago, did you find anything out about this? Or has anyone else tried or done something that relates to this? Was curious about the same thing in my Ginger Beer making process (the kind made with Ginger Beer Plant). It seems interesting, possibly not all that useful, but maybe worth exploring.
