This was my failure
It wa summer time room temp was 30C, I was experiment with a small amount inside a Robertson jam jar.# P/ d% L" H% w, F8 k" s
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.
' t* a- k5 ^) ~' ]; W5 w; {: V1 d0 B2. 2 to 3 hours later, peek at the jar, noticed some bubbling activity inside jar,.% ~6 i& ]! M' |: p
Next day, more bubbling activitiy everywhere. slight alcohol smell.

. P: M# M7 V2 E# Y4th day very little bubbling, shaked jar hoping to improve activity, (this could be the mistake)
' ]* o9 ~5 q) c) |0 ~5th day no bubbling,

1. 1/2 jar of air inside jar might has germs that ruined reaction
' X# X% X) _7 i' q. s2. cleaning not complete.
