Brewing sake: Day 1

Last night I got my sake kit in the mail. It has:
- 64 ounce brown glass bottle
- 400g bag of rice, koji, yeast, and lactic acid
- A bubbler that lets CO2 out of the bottle but nothing else can get in
The kit was about $35. It was pretty easy to get going. I took 1.5 liters of hot tap water and put it in the glass jar with the rice/koji/yeast mixture. Then I put the bottle in the sink filled with hot water for 5 hours to get the fermentation process started. I let the water cool down naturally over night and this morning I put the bottle down in the basement where it will stay for the next 2 weeks while the yeast does it’s thing.
