Not seeing liquid after a week

[James Jordan]

I am making rice wine, but I've used some techniques from sake recipes. I started on day 1 adding rice and koji kin. I wanted to let that do work on the rice for a day or two before adding yeast. At about 36 hours I added more rice, koji, and introduce chinese yeast ball. I kept on adding rice, koji kin and yeast for the following 4 days. I can see it fermenting through the carboy, but I'm not seeing any liquid yet except for a small amount of condensation on the container. Any ideas?

Just to make sure we are on the same page; koji kin are the koji spores while koji is rice that results from having been inoculated with koji kin and incubated until nice white and fluffy or there abouts.

 

Given this, my reading of your question is that you are missing the koji in your process. The koji has the enzymes that are needed to liquefy the rice.

My bad, yes. I used koji rice, not the spores themselves.

[James Jordan]

Just to clarify, I used the spores to make the koji rice, and the koji inoculated rice is what I added to the mixture. I didn't mention the 48 hour period I spent making the koji rice because that seems to have worked fine. I also think the wine is okay, I'm just concerned that there isn't any liquid yet. I'm seeing a lot of activity from the carboy.

OK, then, I next guess would be about getting the enzymes from the koji to the rice. This is just a question of mixing in the right conditions. Koji dry or moist. Rice dry or moist. Any water added? Well mixed. If the rice with warm and moist it should work better. Adding a little water to help the enzymes move around should help a lot.

So I added rice multiple time, but it was usually always still warm. Within an 60-90 minutes after steaming so it was still sticky and somewhat moist. The koji itself has been stored in the refridgerator since it was made. So cool, but not completely dry as the first day or two I saw condensation on the inside of the bag.

So maybe mix it up again and add a little bit of water?
