According to official epidemiological data, it is uncertain whether white wine can effectively kill the novel coronavirus. Scientists have studied the physicochemical properties of the new coronavirus and confirmed that 75% ethanol (commonly known as medical alcohol concentration) has a significant inactivating effect on the virus, but the concentration of alcohol contained in white wine in daily life is not that high, so its effectiveness in killing the virus is not certain. If you want to disinfect household items, it is best to choose medical alcohol. In addition, viruses are sensitive to UV light and heat. Heating at 56°C for 30 minutes or irradiating with a UV lamp for 30 minutes can effectively inactivate them. There are also fat solvents such as ether, chlorinated disinfectants, peroxyacetic acid and chloroform that can effectively extinguish viruses.
