The AEG Santo 75598 KG refrigerator has a built-in wine cooler (no, not the Bartles & James type of wine cooler, although you certainly could use it for those- no judgements here). The stainless steel side by side model comes complete with a separate wine section that can hold up to 39 bottles. The wine cooler features a LED temperature display and a restaurant style UV protected glass door to keep your vino at it’s optimum temperature. I would assume that having a combined wine cooler and regular fridge/freezer would have some sort of energy savings benefit; it certainly has some space saving benefits. This appliance retails for close to $6000 which is a small price to pay for the luxury of always having your Montrachet 1978 from Domaine de la Romanée-Conti ready to pour on a moments notice.
