Protection against 

ultraviolet light

L

ight, in particular the invisible rays from the ultraviolet 

spectrum, is a common cause of undesirable chemi-

cal reactions in wines. The consequences of light-damage 

are visible to the eye: pale red wines, and white wines that 

take on a golden-yellow colour. »Light-strike« (or »Gout de 

Lumiere« as the French know it) destroys the wine’s balance 

and fl attens its aroma and, to avoid it, most producers 

bottle their wine in brown or green glass, which absorbs a 

great deal of the UV rays. However, this alone is not enough for 

bottles that are not stored in the dark. Slight temperature 

increases caused by light radiation can also damage the 

wine – they make it age quicker thereby altering the natural 

development processes, even to the extent that the wine can 

be permanently destroyed.

Insulated glass doors with UV protection.  To minimise the eff ects of UV rays, Liebherr wine cabinets are fi tted with special 

UV-resistant insulation glass. The UV protection is provided by a special dual-pane structure, which incorporates an inner, tinted-glass 

pane and an outer, metallised, low-E (low-emittance) pane. This glass composite refl ects nearly all the damaging UV radiation and 

prevents any deterioration of the wine. 

LED lighting concept.  This innovative technology ensures that the interior of the appliance is evenly lit without any UV radiation, as 

the LED light spectrum does not contain any UV rays. Furthermore, because of minimal heat generation with LEDs, the wines can be 

illuminated and beautifully presented for much longer without any localised heating of the bottles.
