Rose is a cold-tolerant perennial evergreen or deciduous shrub. Every year, many new variants are bred in various countries around the world. At present, there are more than 10,000 variants in the world. In addition to the ornamental flowers, roses can also be used as a flower tea. Recently, some people have promoted “flower wine”, using organically cultivated roses for brewing, turning them into bright red rose wine, while keeping the original wine color, fragrance and taste.
