Total protection against UV and IR radiation

ULTIMATE offers total protection against harmful UV and IR radiation, while still leaving the bottles in full view.

 

The electrically powered doors on the ULTIMATE have a special nano-technological exclusive barrier which, although completely transparent, is totally impenetrable to type A ultraviolet rays.

Radiation of between 375 and 440 nm is extremely harmful to all wines, since it acts as a catalyst for the riboflavin which first goes to the excited state and then back to the non-excited state, releasing energy and causing oxidation of the sulphur-containing amino acids which are found naturally in wine (such as methionine and cysteine). This leads to the formation of sulphurous compounds (such as DMS, DMDS and hydrogen sulphide) which, even in minimum quantities, cause an unpleasant alteration in the aroma and taste of the wine, known as “goût de lumière”*.

Infrared radiation is also blocked by ULTIMATE’s special barrier doors, preventing dangerous heating up of the bottles in the sun: when wine is exposed to the sun, it can be damaged by continuous and repeated changes in temperature.
