Visible light – The short answer is that light can definitely affect the wine. But we need to take a closer look at the physics and chemistry of it all. To understand why and how the so-called light reaction-strike, which can deliver off-the smell of wine, what the French call gout de lumpier. All forms of radiation, including ultraviolet (UV) visible light and X-rays. It has an energy that is proportional to the frequency or inversely proportional to their wavelength. High frequency waves have short wavelengths, and vice versa. And the greater the energy, the greater the catalytic effect of chemical reactions in the wine….
