Alcohol is created through fermentation process of grains, fruits, or vegetables. Meanwhile, fermentation is a process of using yeast or bacteria to change the sugars in the food into alcohol.
For example, rice wine is an example of alcoholic drink. The process of making rice wine starts with a plain water and then mixed with sugar. Then, cooked glutinous rice soaks in the water in a sealed bin. Here comes the secret recipe, the yeast is a specially made then put into the water. The yeast is in a dried cake form. The more you put, the stronger your wine will result.
This would answer the period of time when the rice wine can be consumed. It does not matter whether it is one month, one year, or even one week. As long as all the processes are done, you can drink it straightaway. But the ‘kick’ is not that good. So, the minimum time for the best quality rice wine will take a month and on. The longer the better, instead.
