It wa summer time room temp was 30C, I was experiment with a small amount inside a Robertson jam jar.
- b. ]! ]0 F" P; E1. 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.
8 O8 F. V# K, }1 A" f( {) I; f: K2. 2 to 3 hours later, peek at the jar, noticed some bubbling activity inside jar,.) y$ ]: I0 _7 Q6 s& }, C0 p- w

L" z% |# Y R/ hConclusion -- when compare with your steps, these are the reasons of failure :-
' }$ a( w& K- \! P- \; [. ^. g6 o5 \; `* f& k
1. 1/2 jar of air inside jar might has germs that ruined reaction
3 b; Y, d" g0 `( L0 z7 Y2. cleaning not complete.
