Optimum air quality ___ The quality of the ambient air is essential if the wine is to develop fully and be enhanced during storage – any airborne contaminants can be transferred to the wine and spoil it. ___ Classic natural corks very adequately keep the wine 08 in the bottle, but in no way do they hermetically seal it. As a result, air, which is far more than odourless oxygen, infi ltrates the bottle passing down the edges of the cork. If the bottles are stored in a cardboard box, the wine can take on the odour of the cardboard. But food odours in particular present problems. When storing wine at home, especially in a kitchen environment, wines will almost certainly lose their »terroir and type« characteristics – i.e. they will spoil! Although glass stoppers and screw caps provide airtight closures for bottles, wines inevitably age more slowly because only the oxygen in the bottle is available to them. Synthetic corks allow too much air into the bottle, making them much less suitable for long-term storage of wine altogether. Optimum air quality with Liebherr Optimum air-freshness. All Liebherr wine cabinets are fi tted with FreshAir activated-charcoal fi lters, which ensure optimum air quality within the appliance. The active-charcoal reacts with any contaminants, binding them to its surface, and thereby fi ltering them from the incoming-air. In the Vinidor appliances, each individual wine zone has a FreshAir activated charcoal fi lter. Only the Vinidor appliances UWT 1682 (TipOpen under-worktop appliance), UWTes 1672 (under-worktop appliance) and WTes 1672 (table height, under-worktop) have one FreshAir activated charcoal fi lter in the divider to fi lter both zones. This prevents odours from the ambient air aff ecting the taste of the wines stored in the interior. Filters should ideally be replaced once a year. They can be ordered as an accessory and are easy to replace. Ideal humidity. If wines are to be stored for prolonged periods, the correct humidity is essential. At humidity levels below 50%, even the best natural corks start to shrink. This allows more and more oxygen to penetrate the bottle, and evaporation to occur; and, as the fi ll level drops, oxidation increases. Wines become gradually sweeter until they spoil completely. However, with humidity levels of at least 50%, Liebherr wine cabinets ensure the best conditions for both corks and wine. Thanks to an impressive vaporiser system and specially regulated air circulation, high humidity levels are sustained in all wine storage cabinets. Our Vinothek multi-temperature wine cabinets, with graduated temperature zones, are fi tted with porous lava stone, which controls humidity within these appliances.
