What happens if I don't saccharify rice wine semi-solid enough or if I over saccharify it?

Rice wine is a drink made from rice. Home made rice wine is difficult to aseptic environment, so in the surface of the mash or wine is prone to mold, generally if it is black or white mold or mycelium, will not affect the taste and hygiene of the rice wine, digging it out before eating can be, but if it is yellow, green, grey and other colors of the mold, well don't eat it.
