rice wine brewing stuck

I am trying to make glutonous rice wine, purchased the Angel rice yeast (amalyze) from asian market, the white cookie/powder broke rice down into sugar.

I have measured, it is 40%, very sweet to taste. But it just does not ferment. The sweetness always there, does not reduce. The liquid pools out is very sweet. .does that means it has being converted from starch to sugar already ?

I tried to pitch the champage yeast into it, it only last 2 days, before bubbles stopped. Why?

Is it too sweet (40%Brix) for champage yeast?

Thanks

If I understand correct, then amylase powder is used to turn rice into sugar?

40° Brix is a gravity of 1.180. Champagne yeast can endure a lot, but starting from this amount of sugar would lead to an ABV of 23.6%, if your yeast could endure that. I find champagne yeasts of 15%.

So yes, your yeast has had a good time, but the alcohol level is too high. I would suggest to dilute your brew with the same amount of boiled and cooled water, add wine nutrition salts, and again some champagne yeast to make sure that your mix is completely fermented.
