Comparison Dunavox DX-29.80DK vs Dunavox DX-28.88KF

The maximum number of standard wine bottles (straight, Bordeaux type) that the cooler is designed to store.

The increase in capacity affects the dimensions and price of the entire device. So for private home use, a compact wine coolers of small capacity (up to 20 bottles) can be the best choice — especially since the height of such devices is usually small. However, low wine coolers can store more contents — 24 – 25 bottles or more. Models with a capacity of 50 – 80 bottles are already designed mainly for bars and restaurants, but they can also be useful for enthusiastic wine collectors; and the most voluminous of modern wine coolers can hold noticeably more than 80 bottles — in some units up to two or three hundred.

It is also worth noting that it is not recommended to fill wine coolers to their full capacity. The actual occupancy should be at least 30 percent lower than the maximum. So, when choosing, it is worth making an appropriate margin.

— Climatic. Wine coolers with one temperature zone: one temperature is maintained throughout the entire volume of the working chamber. Such models are designed only for storing wines; different types at the same time (red, white, etc.) — they can all be normally stored at the same temperature. But the optimal serving temperature is just different, and a temperature cooler is better suited to prepare for serving.

— Temperature. Coolers with several zones with separate temperature control. The meaning of this design lies primarily in the fact that different types of wine have different recommended serving temperatures, which, moreover, differ from the optimal storage temperature; see "Temperature zones" for details.

The number of temperature zones provided in the working chamber of the wine cooler.

The temperature zone is a part of the working chamber with its temperature mode, independent of the rest of the volume. In climatic coolers (see "Product type") there is only one such zone — this is quite enough for storing wines, even different types. But it is recommended to serve different types of wine at different temperatures, and all these temperatures differ from the 10..12 °C required for storage. Accordingly, additional temperature zones are desirable in preparation for serving. Moreover, the more these zones, the more types of wines can be kept ready for serving at the same time, but the more expensive the unit is. Thus, most multi-temperature models have only two zones — for storage and for serving; the latter can be reconfigured for different types of wines. More zones — 3 or more — are found mainly in high-end high-capacity coolers.

The total volume of the wine cooler working chamber (chambers).

Although the main spec of such units is the number of bottles (see above), volume data can also be useful when evaluating and comparing different models. The fact is that with the same capacity, a larger volume means better air circulation and more efficient temperature distribution. On the other hand, an increase in volume also increases the price and dimensions — and there may simply not be free space for a wide or high wine cooler.

The highest temperature in the working chamber that this model can provide.

Note that the optimal temperature for storing different wines is the same — about 10..12 °C; any wine cooler can work in this mode. And higher values may be required mainly for preparing red wines for serving — such wines, depending on the type and taste characteristics, should be served at a temperature of 13 to 18 °C. One can be found more detailed recommendations on this matter in special sources. However, the higher the maximum temperature of the wine cooler, the more opportunities it offers for adjusting the microclimate.

Note that an increase in temperature can be useful during storage, and not only for red wines: under such conditions, the ripening process is also accelerated.

The number of shelves provided in the design of the wine cabinet.

Such shelves are usually mounted on rails and can be removed if necessary. In some models, they can also be rearranged to another level. All this can be useful for organizing the space inside the cooler — for example, to accommodate large bottles of increased thickness, you can remove one of the shelves, providing the right amount of needed space. As for the quantity, it is selected by the manufacturer, taking into account the capacity, width and height of the working chamber, so this parameter is not that important when choosing.

The ability to place bottles in the cooler vertically or at an angle(cork up).

This placement provides two advantages. Firstly, the sediment formed in the bottle sinks to the bottom, and the drink becomes optimally suitable for serving. Secondly, if the cabinet has a glass door, one can see the bottles with labels, not just corks or bottoms, as in horizontal placement. On the other hand, note that for long-term storage (a month or more), an upright or tilted position is not suitable: the cork is not washed with wine, which dries out and begins to let in excess air. So even in large spacious coolers, only one or two shelves are usually provided for such a position — the rest are for horizontal storage.

The type of control for wine coolers is indicated primarily by the type of control panel, and its location is also taken into account. According to these criteria, in our time, the following options are distinguished: internal rotary knobs, external rotary knobs, internal push-buttons, external push-buttons, internal touch controls and external touch controls. In details:

- Rotary knobs. The simplest type of control. It is quite rare due to poor comfort and tuning accuracy. And for wine coolers, which are not budget devices, this solution looks very doubtful.

- Push-buttons. A fairly convenient, practical and at the same time inexpensive way, suitable for both models with basic capabilities and advanced units; at the same time, buttons are simpler and more compact than rotary knobs and cheaper than touch controls. Therefore, this option is very popular in modern wine coolers.

- Touch controls. Such touch panels are somewhat more expensive than push-button controls, but this is almost imperceptible against the price of the entire cooler. Touch controls are made only electronic, so it is accurate and as functional as possible. At the same time, the touch controls give the device a technological appearance and do not accumulate dirt due to the...absence of unnecessary slots and protruding parts. Note that this type of control is very convenient for coolers with thermoelectric cooling and is used in most of these models, although it is often found in compressor units.

It is worth noting that all types of controls can be both hidden and placed behind the door (internal) and available for settings without opening the door (external). The first option is more pleasing in terms of aesthetics. The second option makes it easier to configure the device.

— No handle (push to open). Wine coolers equipped with doors without any handles. Accordingly, the opening method of such units differs from the usual one: the user needs to press the door lightly. A special closer is responsible for fixing the door; the mechanism securely fixes it and easily opens/closes. This feature does not affect the main functionality, but it can be very appropriate from a design point of view: for example, wine coolers with handleless doors are perfect for an interior in a minimalist high-tech design.

— Hidden door handle. Handle made in the form of recesses on the end of the door. This feature gives the cooler a neat, discreet appearance. In addition, an ordinary handle can be touched by careless movement, but with a hidden one, it is impossible. It is especially relevant in cramped conditions. Of any noticeable drawbacks of such a design, one can only name that it is less “grabbing” and reliable in holding than an ordinary handle. Because of this, some users find hidden handles less convenient; in addition, the aesthetic tastes of buyers are also different.

— Ordinary handle. Handles of a traditional design protrude noticeably on the door. Although the hidden design has several advantages, quite a few buyers still prefer the classic design. The main motive here is that ordinary handles can be gripped more securely, require less effort to open the door and are...generally more convenient to use. In addition, some users simply like the appearance of doors with handles.
