Comparison Caso WineSafe 12 Classic vs Caso WineCase Red 12

It is the lowest temperature in the working chamber that the model can provide.

Note that the optimal temperature for storing different wines is the same — about 10..12 °C; in this mode, almost any wine cooler can work. And lower temperatures may be needed primarily to prepare different types of wine for serving. So, the optimal temperature for most white and rosé wines is considered to be 8...12 °C. However, a lower temperature may be required, and sparkling wines (champagne) are usually served "icy", with a temperature not exceeding 7 °C. One can be found more detailed recommendations on this matter in special sources. In addition, lowering the temperature may be required for storage — it slows the process of wine maturation.

Anyway, the lower the minimum temperature in the wine cooler, the wider the possibilities for setting the climate.

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.

It is the principle by which the wine cooler system works. In modern models, compressor or thermoelectric type of cooling is most often used, much less often — absorption. Here are the features of each option:

— Compressor. The same principle as conventional refrigerators works: due to the operation of the compressor, a refrigerant circulates through the cooling circuit, which takes out excess heat from the working chamber and brings them out through the radiator. This cooling method is reliable and efficient; it allows you to provide almost any conditions inside the working chamber, regardless of the ambient temperature. In addition, compressors can even be installed in built-in units. Such systems are prone to vibrations and are highly undesirable when storing wine. However, wine coolers often use special compressors with a low vibration level, as well as cushioning systems (see "Features"), which reduces this disadvantage to zero. However, these measures significantly affect the cost, although compressor systems themselves are not cheap.

— Thermoelectric (Peltier). Cooling using thermoelectric plates, so-called Peltier elements. When current is passed through such a converter, one side of the plate is cooled, and the other side is heated. Thanks to this, in wine cabinets of this type, it is possible to implement not only cooling but also heating. Thermoelectric systems are much simp...ler, more reliable, more compact and cheaper, compared to compressor coolers. On the other hand, with higher power consumption, they have lower performance. And the efficiency of Peltier elements is not very high — in particular, they do not cool to a certain temperature but to a certain number of degrees relative to the ambient temperature (usually 10 – 15 °C). In light of all this, mainly wine coolers of a rather small capacity are made thermoelectric. It is also worth saying that for several reasons, such units can not be built-in.

— Absorption. Absorption cooling is carried out due to the absorption and release of heat during certain chemical processes. Such systems have practically no moving parts, thus they are silent and do not create vibrations; their small size allows them to be used even in compact wine coolers. The main disadvantage of units with this cooling type can be called high cost. In addition, they consume a lot of electricity and may contain chemicals that, if the circuits are damaged, are dangerous to humans (for example, ammonia).

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 material from which the shelves of the wine cooler are made.

— Wooden. Wooden shelves are considered the most suitable option for storing wine. It is because the wood smooths out vibrations additionally, which helps protect the bottles from unwanted shocks. In addition, this material looks good and provides a certain style to the wine cooler. Therefore, more or less advanced models that allow long-term storage of wine are equipped mainly with wooden shelves.

— Metal. Shelves of this type are made of thick wire and are grids with bars of a special curved shape: the bends of such bars play the role of "seats" for bottles. Such grids are somewhat cheaper than a wooden ones. Moreover, they almost do not block the air movement in the working chamber and contribute to the evenest temperature distribution inside. On the other hand, metal, unlike wood, almost does not absorb vibrations and therefore is considered suitable mainly for relatively short-term storage of wines.

— Interior lighting. Lighting installed in the working chamber. It allows you to see the contents of the cooler better. Lighting is useful since the working chamber is often in the shade, even in bright ambient light.



— Chamber heating. The ability of the cooler to work in heating mode. In temperature models, heating is used to prepare red wines for serving: we recall that such wines are stored at standard 11..12 °C, but the optimal serving temperature can be up to 18 °C, depending on the wine type. In climatic coolers, this function is designed mainly for cases where the ambient temperature drops below the optimum temperature of the working chamber. For example, in case of problems with room heating. In addition, increasing the temperature during storage speeds up the process of wine maturation, which can also be useful.

— Fast cooling. A special intensive cooling mode designed for situations where a large number of non-chilled bottles must be additionally placed in an already loaded wine cooler. If you do this in normal cooling mode, the temperature inside will rise noticeably, and it may adversely affect the wines already stored in the cabinet. During the fast cooling, excess heat is intensively removed from the working chamber. It helps to avoid microclimate disturbances. It is worth noting that this mode usually needs to be turned on in adv...ance, a few hours before loading a new batch of wine bottles, and turned off after a certain time to avoid overloads. These details must be given in the manufacturer's documentation.

— Chamber ventilation. The presence of a ventilation system in the working chamber of the cooler. Such a system prevents the accumulation of unpleasant odours that can adversely affect the taste of wine, penetrating through corks. Note that in models without a fan, air circulation also occurs, but it is much less intense.

— Humidity control. It is the ability to adjust the air humidity inside the wine chamber. Some wines are very demanding on storage conditions and require not only a certain temperature but also a certain humidity. The humidity control function allows you to set its optimal value. In addition, the humidity should not be lower than 70%. Otherwise, the cork dries out, and an excessive amount of air gets into the bottle, which accelerates the oxidation of the wine and worsens its taste.

— Charcoal filter. A special filter that removes foreign odours from the air in the wine cooler. Wine bottles are not completely sealed — some air constantly enters through the cork, which has a porous structure, and strong odours can thus enter the bottle and adversely affect the taste and aroma of the wine. The charcoal filter helps to avoid this. Note that it must be replaced from time to time.

— Anti-vibration system. System for smoothing various vibrations and shocks affecting the wine cooler. Such influences are extremely undesirable for storage — they disrupt the course of biochemical processes and can even spoil the product. The presence of an anti-vibration system is relevant mainly for coolers with compressors (see "Cooling type"). It is the compressor circuits that are most susceptible to vibrations. If such a unit does not have such a function, it is a low-cost model not designed for long-term and thorough storage of expensive wines. Or it is a device with a high-quality compressor, which initially has a low vibration level and can be used without special protection against them. As for thermoelectric cabinets, the fans used in them are also potential sources of vibration but not as intense as compressors. Therefore, in such units, an anti-vibration system rarely occurs.

— Reversible door. It is an ability at your discretion to choose the direction in which the door of the wine cabinet will open. This function allows you to adjust the design to the location; it can be useful in cramped conditions, where the door can normally open only in one direction.

— Door alarm. It is a system that monitors the closing of the wine cooler door. If the door is not closed for a long time or is not closed tightly enough, an audible or light (depending on the model) signal is given. It avoids a critical change in temperature and humidity in the wine chamber and preserves the quality of the wine.

— Failure indicator. It is a system that monitors the state of the wine cooler units and gives a signal in case of failure. It allows you to avoid unpleasant consequences, ranging from a critical change in storage conditions and damage to wine ending to serious breakdowns and even accidents.

— Child lock. A special lock designed mainly to prevent a curious little child from getting to the contents of the wine cooler. The child lock is turned on and off in a special way that does not create problems for an adult but is not available for a child. And in some models, such a lock is closed with a traditional key. It can also be used for general protection against unauthorized access to the contents of the wine cooler.

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.

It is the amount of energy consumed by the wine cooler in a year during normal operation. Of course, the actual consumption will inevitably differ from this indicator in one direction or another, but these differences are usually not fundamental. So this indicator makes it possible to evaluate the efficiency of different models and compare them with each other. Recall that more energy-efficient units cost more on their own, but in the end, they can turn out to be more profitable due to energy savings.
