Types of coffee for which the coffee maker was originally designed.

— Ground. Traditional ground coffee; the easiest way is to buy such a product in finished form, but if you wish, you can grind it yourself from whole beans. And if this option is specified for a model with a built-in coffee grinder (see above), this means that both beans and pre-ground coffee can be loaded into it.

— In grains. This option means that the coffee maker is equipped with a built-in coffee grinder by definition, which means that you can grind beans in it immediately before brewing, which allows you to maximize the taste and aroma. For more information about the other benefits of this option, see "Built-in coffee grinder". Also note here that some coffee makers with this function also allow the use of ground coffee (see above), others work exclusively with beans from their own coffee grinder and do not require loading a powder that was ground separately.

— Capsules. Ground coffee, packaged in special capsules; usually, one such container is used to prepare one serving of the drink. Capsule coffee makers are extremely simple and easy to use: just load the capsule, turn on the making and wait for the end of the process, and then remove the used container. The capsules themselves can be both disposable and reusable. The advantage of the first option is that the human fac...tor is eliminated from the brewing process: each capsule contains a standard portion of coffee, and each next cup is no different from the previous one. In addition, disposable containers are hermetically sealed and can be stored for a long time without loss of quality. Their disadvantages are the limited flavors, the high final cost of the drink (almost twice as expensive as using beans or ground coffee), and the fact that different manufacturers of coffee makers use different capsule formats. Reusable capsules can be refilled with ground coffee to your taste, they are cheaper, but not suitable for long-term storage and require thorough cleaning when changing coffee sorts.

— Pods (cialda). A type of portion packaging in which roasted ground coffee is packed in a special filter, most often paper; each such filter is stored in a sealed bag. From a practical point of view, pods are very similar to disposable capsules (see above). On the one hand, the preparation of such coffee is extremely simple, convenient and does not require any special skills: just load the pod, turn on the coffee maker and wait for the preparation; and sealed packaging allows you to store such coffee for a long time. But pods do not allow you to experiment with different sorts, grinding levels and preparing features, and the selection of sorts and flavors among them is rather limited. In terms of one cup of coffee in pods, it is cheaper than a drink from disposable capsules, but still more expensive than coffee from ground beans.

On a separate note some models of coffee makers allow the user to use several types of coffee at once. For example, in the holder of some manual espresso coffee makers (see "Type"), both a portion of ground coffee and a pod can be loaded.

The number of cups of coffee that can be prepared in the coffee maker at one time.

The meaning of this characteristic may be different, depending on the design of the coffee maker. So, if the device does not belong to geyser models or electric Turks (see "Type"), and also does not have its own coffee pot (reservoir for finished coffee), the number of cups is indicated by the number of pouring spouts. Among such models, devices for two spouts, that is, for two cups, have become widespread: they are convenient not only for preparing coffee for two people, but also for recipes that require a double portion of espresso. Options for one spout are much less common, these are mostly compact and relatively inexpensive models.

In turn, for Turks and geyser coffee makers, the number of servings is determined by the capacity of the water tank (see below), and for models with their own coffee pot, by the capacity of the coffee pot (it also approximately corresponds to the capacity of the tank). Moreover, the counting is also carried out in different ways. In electric Turks, geyser models, as well as espresso coffee makers with a container for ready-made coffee, 60 g of drink is usually considered per portion — the maximum volume of one cup of classic espresso; for filtration models — twice as much, 120 – 125 g (standard portion volume of filter coffee). In all these cases, the number of cups can be ...href="/list/95/pr-2472/">three or more, and many coffee pots generally hold 10 — 12 portions.

The volume of the water tank provided in the coffee maker; for turkish electric coffee pot (see "Type"), this paragraph indicates the actual working volume of the turk.

The larger the tank, the more coffee you can make without refilling the device; on the other hand, a large capacity, respectively, affects the dimensions, weight and price of the device. Therefore, manufacturers select this parameter in accordance with the general level of the coffee maker and the features of its intended use. So, you rarely have to make more than two cups of coffee at the same time, and 300 – 400 mL for such cases is usually more than enough for home use. And for use in a coffee shop or restaurant, where coffee is made often and in large quantities, large-sized devices are produced, the volume of which is already calculated in liters; recommendations for choosing the volume of a coffee maker for professional use can be found in special sources.

The coffee maker has its own milk capacity. Technically, to prepare various types of coffee with milk, you don’t necessarily need your own container — you can use any tank with milk by lowering the straw from the coffee maker into it (or even prepare the milk separately and add it manually). At the same time, the presence of a special container usually means that the coffee maker has its own programs for preparing coffee with milk — cappuccino, latte, etc. (see "Provided programs"). In addition, your own milk tank is usually more convenient than third-party containers, and it takes up less space.

— Heating cups/coffee pot. Some coffee makers have a heater for cups or a coffee pot. The purpose and design of this function vary depending on the type of coffee maker. For espresso coffee makers, the heater is in the form of a platform on the top of the machine, where cups are placed to be preheated before pouring espresso or espresso-based drinks. This is believed to enhance the taste and experience of the coffee. In filter coffee makers, the heater is integrated into the stand for the coffee jug, ensuring that the brewed coffee remains hot and ready to serve for an extended period of time.

— Self-cleaning. The coffee maker is equipped with a self-cleaning function, which automatically removes scale, coffee bean residues, and other impurities. The process and effectiveness of self-cleaning may vary between different models, but overall, this function significantly simplifies the maintenance and upkeep of the coffee maker.

— Water filter. Coffee makers may include a built-in water filter to purify the water used in the coffee preparation process. These filters operate similarly to filter jugs, with a filter cartridge installed in the water tank. The water passes through the cartridge, ensuring improved water quality before reaching the brewing unit. It's important to note that the presence of a filter is specific to coffee makers that are originally equi...pped with such a cartridge. The capabilities of the filter may vary, but it is particularly useful if you have concerns about the water quality or want an extra layer of assurance. However, it's important to keep in mind that the filter elements need to be replaced periodically, which incurs additional costs.

— Display. A small external screen enhances the visual operation of the coffee maker. This screen displays various service information such as the active brewing program, the completion time, the remaining water volume in the tank, or the coffee level in models with a built-in grinder. It can also provide warnings about any emergency situations that may arise during the brewing process. The inclusion of this external screen allows for more convenient monitoring and control of the coffee maker's functions. We emphasize that in this case we are talking about traditional displays; touch screens are listed as a separate feature (see below).

— Touchscreen. A touch-sensitive screen, similar to those found in smartphones and tablets, is incorporated into the coffee maker. This screen not only displays various information about the device's operation but also serves as the control interface. The use of a touch screen often enhances convenience and visual appeal compared to traditional control methods such as buttons or knobs. The screen can dynamically display a wide range of visual elements, including buttons, sliders, and counters, depending on the current task. However, it's important to note that touch screens are typically found in high-end coffee makers due to their higher cost and extensive feature set.

— Touch buttons. The coffee machine's control panel features touch buttons, which offer several advantages over traditional mechanical buttons. Firstly, they require only a light touch instead of applying force. Secondly, the touchpad contributes to the coffee machine's sleek and modern appearance. Thirdly, the absence of gaps or protruding parts on the panel makes it easy to clean. However, it's worth noting that touch buttons can be more expensive and are typically found in advanced models, particularly in the middle to high-end range. It's also important to mention that touch buttons can be combined with a touch screen, although in many cases, coffee makers with touch buttons may feature a regular display.

— Control via the Internet. The coffee maker offers the convenience of remote control via the Internet. This feature can be accessed through a dedicated smartphone or tablet application or by accessing a specific webpage on any browser. With this function, users can control the coffee maker from anywhere in the world with an internet connection. It allows them to monitor the coffee maker's status, such as the current program in operation, remaining coffee or water levels, and error messages. While controlling the coffee maker via the internet may not be necessary when traveling to a different continent, it can be beneficial for various scenarios, such as pre-ordering a favorite drink on the way home from work or checking coffee supplies and purchasing more if needed. The coffee maker typically connects to the internet via Wi-Fi.

— Smartphone control. The coffee maker offers the convenience of remote control from a smartphone or other compatible device through a dedicated application. By installing the application on their device, users can turn their gadget into an interactive remote control for the coffee maker. This allows them to not only give commands to the coffee maker but also monitor its operation parameters and receive notifications. The advantage of this function is its convenience, as users no longer need to physically approach the coffee maker. The connection between the device and the coffee maker is typically established via Wi-Fi or Bluetooth, enabling reliable communication within a short range, even through walls. It's important to note that this function is distinct from control via the internet (as mentioned earlier), as it involves a direct connection between the coffee maker and the control gadget.

— Cooking timer. The coffee maker features a convenient delay start function that enables users to program the device to begin the coffee preparation process at a specific time in the future. For instance, users can set the coffee maker in the evening to have freshly brewed coffee waiting for them in the morning. Some advanced models even offer multiple timer settings, allowing users to schedule coffee preparation at different times throughout the day or on specific days of the week. This feature provides added flexibility and convenience to suit individual preferences and schedules.

— Child lock. Introducing a lock feature for the coffee maker's control panel will prevent children from accidentally turning on the device or altering its operating mode. This lock can be deactivated through a method, such as pressing multiple keys simultaneously, that is easily accessible to adults but not to children.

— 2 boilers. The coffee maker is equipped with two separate boilers for heating water. This design allows for a more efficient and faster preparation of various drinks. One boiler is dedicated to heating water for coffee, while the other generates steam for milk frothing. Without this specialization, the process of making cappuccinos and similar drinks would be time-consuming, requiring waiting for the boiler to switch between modes. Having two boilers eliminates the need for mode switching and significantly speeds up the process. Additionally, some models use a thermoblock instead of a traditional boiler for heating small portions of water directly supplied to the holder during brewing, further enhancing efficiency.
Anyway, this design is especially convenient in coffee shops, restaurants, etc., where you have to prepare different drinks and the speed of preparation is important. But if the coffee maker is planned to be used mainly for coffee drinks without milk, this function will be rather redundant.

— Thermometer. Incorporating a built-in thermometer into the coffee maker design enables precise measurement of water, milk foam, and the final drink's temperature. This feature allows for accurate control of the brewing process, which is highly valued by professional baristas and coffee enthusiasts who pay attention to every detail of their favorite beverage. Some thermometers are mechanical, resembling a dial with an arrow. While they may not be as precise as digital thermometers, they add an interesting and stylish element to the coffee maker's aesthetics. These mechanical thermometers often indicate temperature ranges, such as "low temperature," "optimal," and "high," using different colors on the scale rather than specific numerical values.

— Manometer. An indicator that displays the pressure in the coffee maker tank. This function is found mainly in espresso coffee makers (see “Type”): an increased steam pressure is required to make espresso, while a pressure gauge allows you to control the status of the coffee maker and check whether it is ready for use. Also, such equipment will be useful from a safety point of view: you cannot open a pressure tank, you must first make sure that it has decreased to a safe level.

— Tamper. The built-in tamper is a special device for tightly compacting coffee in the holder of an espresso coffee maker. This step is essential for achieving the desired brewing quality, as proper compaction ensures optimal density and even extraction of the ground coffee particles. While separate tamper devices are available, resembling round seals, many professional baristas prefer the convenience of built-in tampers. The main advantage is that the tamper is always in a fixed position, reducing the risk of misplacement and ensuring easy accessibility. Some advanced coffee makers with built-in grinders even integrate the tamper into the coffee dispensing mechanism, allowing users to simply turn a lever after loading the holder to tamp the coffee. Such systems are not only user-friendly but also ensure consistent tamping quality regardless of the user's skill level.

— Increased thermal insulation. The presence of reinforced thermal insulation in the tanks of the coffee maker. The general principle of this design is that the tank is equipped with double walls, in the space between which there is a vacuum or a layer of special thermal insulating material. This design minimizes heat loss, ensuring that the contents remain warm for an extended period and preventing unnecessary energy consumption for reheating. The specific tank that uses additional thermal insulation depends on the type of coffee maker. In filtration models, this pertains to the container for the brewed coffee, while in espresso machines, it applies to the milk container. It is not necessary to provide additional insulation for the water boiler in espresso machines due to various reasons, such as the use of thermoblocks with flow heating principles in many espresso machines.

Power consumption of the coffee maker. Usually, this indicator is comparable with the power of the heater installed in the device.

This parameter is selected by the manufacturer, taking into account other performance characteristics (type of device, tank volume, additional functions, etc.), so that the coffee maker can effectively cope with its tasks. Therefore, in fact, power is of secondary importance: it is worth deciding first of all on other practical points, and only then look at power when choosing. In general, a more powerful coffee maker (ceteris paribus) will quickly cope with the preparation of coffee, but it will also cost more.
