Cellars demand lighting solutions that take care of wine and champagne natural properties.
The challenges
Photo-sensitivity
Wine and champagne are negatively affected by natural light and fluorescent or halogen lamps, due to UV rays and heat. This is why cellars and bottles are usually dark.
Riboflavin
During alcoholic fermentation, yeasts produce riboflavin. Part of the energy emitted by the light source is absorbed by riboflavin, which triggers chemical reactions. How does light affect wine and champagne through riboflavin?
How does light affect wine and champagne through riboflavin?
| Color | It causes progressive discoloration, so wine and champagne may become colorless. |
| OLFACTORY AND VISUAL PROPERTIES | Sensory characteristics can be modified, and flavors that reduce aromatic or fruity characters appear. |
| Aging | It causes new compounds that contribute to light-struck taste and atypical aging, with an accumulative effect. |
UV radiation
LED technology does not emit UV rays, but their blue wavelengths are harmful because the riboflavin spectrum has an absorption peak at 440 nm (between violet and blue), which can increase negative effects.
The absence of UV radiation and blue wavelength benefits the storage of wines.
Cool areas
Temperatures are higher than 21ºC cause premature aging and flat aromas and flavors.
LED light sources do not generate significant heat, so they contribute to a cool ambient while improving their lifetime.
Humidity and dust Wines are stored at cellars with 50-80% humidity during long times, so bottles accumulate dust.
Sealed luminaires protected against the income of solid and liquid elements last long and ensure light quality.
Safety
In working areas, it is needed to combine the protection of the wines with worker’s safety and comfort. The light must guarantee maximum visual comfort, flicker-free, and low glare, to avoid visual fatigue and allow the identification of a clear risk.
“Wine in a white bottle exposed to direct fluorescence light can suffer deviations of its sensory profile between 1 and 3 hours”
The Solution
- The right light level and color protect wine and champagne against riboflavin effects from photosensitivity.
- Robust and long-lasting luminaires are appropriate to humid and dirty environments.
- LED technology contributes to keeping a cool ambient temperature in cellars.
- Luminaires with easy mounting reduce installation and maintenance costs.
