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.
