This was my failure
It wa summer time room temp was 30C, I was experiment with a small amount inside a Robertson jam jar.
% c2 n& m* v" i( ]& A& C1. 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.6 a8 R; `9 H! J/ H% i
2. 2 to 3 hours later, peek at the jar, noticed some bubbling activity inside jar,.( c6 S7 S2 U" `0 ^5 M& r$ G
Next day, more bubbling activitiy everywhere. slight alcohol smell.
' s. @5 g+ P; Z# N0 xin 3rd day rice broke down from it's shape, stronger alcohol smell, truns darker color
) v7 R4 Y+ ~2 S4th day very little bubbling, shaked jar hoping to improve activity, (this could be the mistake)
% h5 d' u# g2 P0 S+ F$ S- G$ F5th day no bubbling,' i; F) r: A+ r$ Q" c

Conclusion -- when compare with your steps, these are the reasons of failure :-
( e+ i5 ~# Z; w' m5 O7 d
