Caso WineDeluxe WDU 18 built-in wine cooler, 18 bottles, 2 zones, 29.5 cm

The WDU 18 is only 29.5 cm wide and 56.3 cm deep, so it fits a narrow gap inside the kitchen units that would otherwise hold a slim shelf or a bottle rack. The manufacturer gives the height as a range of 81.8–87.8 cm, which helps fit the cooler under a worktop. Exact niche dimensions are not given, so compare the measurements with your kitchen before installation.

Despite the narrow housing, the cooler has two temperature zones, and the temperature can be set anywhere from 5 to 20 °C. One zone keeps cooler white or sparkling wine, the other warmer red. Four wooden shelves hold the 18 bottles lying down, which keeps the corks moist and lets you reach each bottle on its own.

The cooler can be controlled with the CASO Control app, which connects through Wi-Fi Smart Control on both Android and iOS phones. The app lets you check and change the temperature without walking over to the cooler. The LED display on the unit shows the settings when your phone is not at hand, and the door-open alarm warns you if the door has been left open by mistake.

The door is made of UV-filter glass, which protects the wine from ultraviolet light that can spoil its taste and aroma over long storage. LED lighting picks out the bottles and labels behind the glass. The door is reversible, so the cooler can sit at the left or right end of the kitchen without the open door getting in the way.

The manufacturer gives a maximum noise level of 38 dB and noise class C, so inside the kitchen units the cooler is barely audible even in an open-plan kitchen. On the EU energy label scale from A to G the WDU 18 is rated class F, with an annual consumption of 97 kWh. It runs from a 220–240 V, 50 Hz supply.

Despite its slim housing, the WDU 18 weighs 35.7 kg, so lifting it into the niche is a job for two people. Before installation, check that the gap in the units matches the 29.5 cm width and 56.3 cm depth and that the socket stays accessible. Ventilation requirements and installation steps are described in the user manual.

The Caso WineDeluxe WDU 18 suits kitchens where the only space left for a wine cooler is a narrow gap between units and a 29.5 cm wide housing is what fits. Two zones keep white and red wine at different temperatures, the app and the door-open alarm help you keep an eye on the temperature, and the 38 dB noise level will not disturb an open-plan kitchen.
