2. Add a proper amount of rock sugar equal to that of dried roses, and then pour in white wine, and the ratio of rock sugar to dried roses is 1 6.

3. Finally, the container is sealed and soaked, placed in a cool and dry place, and the roses are fished out in about one month, so you can drink sweet and sour rose wine.
