1. As I said before, it is very simple to make wine from Rosa roxburghii, just use fresh Rosa roxburghii. If you can't pick fresh Rosa roxburghii, buy fresh Rosa roxburghii, or make wine with dried Rosa roxburghii. First cut the Rosa roxburghii with a knife, rinse it briefly, and then drain the water.
2. Next, wash the prepared glass jar, soak it in boiling water for sterilization, and then drain the water inside. The correct way to make Rosa roxburghii wine is never to leave moisture or any oil in the glass jar. Put the quasi-dry Rosa roxburghii in, and then add the white wine. 1: 10 ratio is the best. Sealed again, dry Rosa roxburghii wine needs to be preserved for about three months before drinking.
