Harvested two 1.5 cup (pre-cooked rice measure) batches last night. Both with (China) northeastern short-grained rice - 东北大米. The one with ARL came out nice enough, though probably not as good as my first batch, made with local yeast balls. The other 1.5 cup batch, made with the local yeast, got a bit of mold on it:
I harvested and squeezed it anyway and put it in a 500 mL bottle with a
DIY swingtop (after a couple cheese-cloth filtrations), as I did with the ARL bottle. It smelled quite good at the time, but I wasn't prepared to give it a taste.
Fast forward to this morning: the ARL batch was doing alright, but the moldy batch was a bottle bomb waiting to happen. I foolishly didn't cover the top with anything when I popped it open for pressure relief and ended up getting nasty-smelling, viscous rice wine all over. It was really stinking the place up, so I ended up dumping it.
On the positive side, I did some new batches as well this morning. 6.5 cups (pre-cooked) of the same rice. After it cooled, I made four small experimental batches and one larger regular batch:
The experimental batches were all 300 grams of cooked rice. One with 10 grams of Pu-er tea leaves and 1 gram ARL, one with 10 grams of golden eyebrow red (black) tea and 1 gram ARL, and identical batches with 300 grams of pre-boiled bottled water (a lot more than I expected in comparison to the rice; kind've wish I had used less). The larger batch is 3386 grams of cooked rice and the remaining 4 grams of ARL.
Since temperatures are dropping as winter comes on, I've got the four experimental batches in a water bath at 28 Celsius (water level below the cheesecloth under the lids to avoid contamination) and the larger batch in a 5 liter bucket with an airlock (lid's too tight for cheesecloth), on top of the tub with the experimental batches to catch some of the warmth as well.
