This was my failure
It wa summer time room temp was 30C, I was experiment with a small amount inside a Robertson jam jar.
7 A! U6 J$ p) V. p* L4 h! B+ n1. 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.
+ m* e- J% E3 i* Z: g4 H* {2. 2 to 3 hours later, peek at the jar, noticed some bubbling activity inside jar,.8 [. [ [" n; d6 i- V& Z* f9 D
Next day, more bubbling activitiy everywhere. slight alcohol smell.

Conclusion -- when compare with your steps, these are the reasons of failure :-
$ R) W: z, x+ d/ L) x. H
% c6 B7 g4 U4 c& V1. 1/2 jar of air inside jar might has germs that ruined reaction
9 Z3 q1 M. n8 P z2. cleaning not complete.
|7 ^0 g0 ]* `$ h3. wine yearst was too old or no good ?# c3 Z9 T. |2 G- k, a
