This was my failure
It wa summer time room temp was 30C, I was experiment with a small amount inside a Robertson jam jar.
' O8 g0 Q% u( c& \1. 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.
7 J7 Z" g X. t; i% c+ U" ^9 z2. 2 to 3 hours later, peek at the jar, noticed some bubbling activity inside jar,.6 L# a' l2 P# c h; P! ~
Next day, more bubbling activitiy everywhere. slight alcohol smell.* l4 j, H! }( j+ a8 c
in 3rd day rice broke down from it's shape, stronger alcohol smell, truns darker color( c0 l1 B) E: T9 J& F. W
4th day very little bubbling, shaked jar hoping to improve activity, (this could be the mistake)

Conclusion -- when compare with your steps, these are the reasons of failure :-

1. 1/2 jar of air inside jar might has germs that ruined reaction* N/ G5 W" w4 M8 t5 M
2. cleaning not complete.$ o: T/ J/ c& l# S3 l0 d2 y6 ~
3. wine yearst was too old or no good ?) s, r3 n$ Z6 O- H( z
