There is no way to remedy it but to do it again.

A lot of bacteria will inevitably be produced in the process of self-brewing. If it is brewed by a large enterprise, it will be fully enclosed for disinfection, but home-made brewing cannot solve this problem. But if you choose the right method, you can make your own wine that is both safe and delicious.

1. During the brewing process, you must pay attention to cleaning the container and hands to ensure "no water and no oil", otherwise it will fail.

2. It is best to use non-metallic containers for home-brewed wine, such as glass bottles and glass jars.

3. Choose disease-free grape raw materials. Grapes are not easy to store at room temperature and are prone to mildew. If the freshness is not high, it will be easier for mold to breed in the wine.

Notes on making homemade wine

1. After cleaning the grapes, the grapes must be completely air-dried without any moisture.

2. Primary fermentation should be stirred regularly to allow full contact between the grape skins and the wine body to promote fermentation.

3. After filtration and clarification, it enters the secondary fermentation stage. The container must be full, otherwise it will be easily oxidized and damaged.

4. If you want the secondary fermentation to taste good, you can add some oak chips to it to enhance the flavor.
