The causes of broken rice include over-soaking, excessive water content during steaming, natural cooling, and poor rice quality.

1. The soaking time is determined by the degree of softening of the glutinous rice. The simple method is to crush it lightly with your fingers. Rice can easily break if soaked for too long.

2. Drain the glutinous rice until there are no water drops before steaming. If there is too much water, the rice grains will easily stick to each other.

3. When cooling, rinse with cold boiled water to remove the sticky substances on the surface of the rice grains and disperse them gently.

4. Finally, choose slightly better rice. Aged rice or polished rice is fragile and has a low wine yield.

It is not a bad thing if the wine is too sweet, it means that the sugar conversion rate is high. After a while, the sugar will be converted into wine, the sweetness will decrease but the wine taste will increase, and the rice grains will also cavitate, that is, the wine will become old. If it is too sweet, you can add water to dilute it before eating, or boil liqueur eggs or the like.
