This was my failure
It wa summer time room temp was 30C, I was experiment with a small amount inside a Robertson jam jar.
! F. p4 t4 `9 m, i( r1. wash everything with broiling water, soak glutine rice overnight , using a bowl, cook inside microwave cooker ,( my rice cooker not easy to clean to oil-free stage), rice was properly cooked ( similar to sticky rice in dimsum restaurant ), left at table to cool down to same temp as back of hand, stir occaionly, sprinkle and mix 1 flat teaspoon of wine yearst ( white color, look like the fruit of lychi ), pour content into a jam jar , half full, put a piece of ceram wrap over jam, screw cap , put jar inside cupboard.! j1 `$ T8 m) e$ [1 a6 C4 ?
2. 2 to 3 hours later, peek at the jar, noticed some bubbling activity inside jar,.
% _3 I b- Y" ~% U Next day, more bubbling activitiy everywhere. slight alcohol smell.
B& d5 W* ^) K& o2 W9 N/ Din 3rd day rice broke down from it's shape, stronger alcohol smell, truns darker color
6 M, p# z0 M! {0 [' j4 C2 s4th day very little bubbling, shaked jar hoping to improve activity, (this could be the mistake)
