Comparison Redmond RCM-1511 black vs Vitek VT-1516 stainless steel

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.

Programmes for the preparation of individual drinks provided in the coffee maker.

This list can include both the classic, most popular coffee and hot drinks (espresso, americano, ristretto, cappuccino, latte, latte macchiato, hot chocolate), as well as more specific recipes: espresso macchiato, espresso lungo, double espresso, Flat White, Long Black, cream coffee, etc. Also, the design often provides for separate modes for obtaining hot milk, milk foam and hot water. Here is a more detailed description of each of these options:

— Custom programme. A function that allows the users to create their own coffee recipes according to their preferences. In this mode, users can adjust key brewing parameters such as the degree of coffee grinding (with the availability of built-in coffee grinders in many machines), water temperature, water volume, operating pressure, and more. This feature allows individuals to effortlessly prepare their unique a...nd personalized coffee with just a simple button press. Certain models even offer the ability to save multiple programs and user profiles, catering to multiple individuals with their own sets of recipes.

— Espresso. Classic Italian espresso is one of the most famous and popular coffee drinks. The standard serving volume is 35 mL, it is prepared from 7 g of coffee. Ideally, the drink should have a characteristic light crema. Such coffee has a rich taste and aroma, which is why many consider it perhaps the most “powerful” in terms of impact; however, espresso actually contains relatively little caffeine.

— Espresso macchiato. Espresso (see above) with added milk foam. Such a drink is similar to the cappuccino described below, but it has a smaller volume due to the smaller amount of milk — about 15 mL is added in traditional recipes.

— Espresso lungo. A variety of espresso (see above) characterized by a large amount of water (up to 60 mL instead of 35 mL), a long extraction time and, as a result, a higher caffeine content. In fact, lungo is a cross between classic espresso and americano.

— Double espresso. Also known as "doppio" (espresso doppio). The name fully corresponds to the essence of this drink: it is, in fact, two servings of espresso (70 g) in one cup. The amount of coffee when cooking is also taken twice as much — 14 g instead of 7 g.

— Ristretto. The strongest and most concentrated of the popular coffee drinks, also referred to as "short espresso". With the same amount of coffee (7 g), much less water goes to a serving of ristretto — about 20 – 25 mL.

— Flat White. Flat White is a drink hat consists of a double espresso shot blended with slightly frothed milk. Approximately 110 mL of milk is added to 60 mL of espresso, resulting in a total volume of around 170 mL. Compared to cappuccino and latte, a Flat White offers a more pronounced coffee flavor while still maintaining a smooth, milky aftertaste that is characteristic of this drink.

— Long Black. The Long Black is a drink that shares similarities with the Americano (see below). It is made by combining a double shot of espresso with hot water. However, there are two main differences: firstly, the Long Black uses a double portion of espresso, making it stronger and more concentrated than an Americano. Secondly, when preparing the drink, the espresso is poured into the water, rather than the other way around. This method helps preserve the dense and aromatic foam characteristic of espresso. The standard serving volume for a Long Black is approximately 120 mL.

— Americano. Americano is a drink made by diluting regular or double espresso (see above) with hot water. The typical ratio is between 1:2 to 1:4, resulting in a finished drink volume ranging from 110 to 240 mL, although other volumes and proportions are possible. The addition of hot water softens the intense flavor of espresso and helps to reduce any perceived bitterness, which some individuals may find excessive. While some traditional coffee enthusiasts may be skeptical of the Americano, it remains a popular choice due to personal taste preferences. Ultimately, the enjoyment of this drink is subjective and varies from person to person.

— Coffee crema. A "Black" coffee drink is prepared in a relatively large volume, similar to an Americano (see above), ranging from 180 to 240 mL. The key difference lies in the brewing method. Instead of adding water to pre-brewed espresso, the entire volume of water is passed through ground coffee. Additionally, the coffee used for this drink should have a coarser grind compared to espresso and espresso-based drinks. The term "crema" in the name refers to the thick, nut-colored foam that forms on top of the drink, which is particularly dense in this type of coffee.

— Cappuccino. Cappuccino is a coffee drink made with approximately 4 parts frothed milk to 1 part espresso, resulting in a final volume of around 150 mL. One of the defining characteristics of cappuccino is the generous amount of milk foam on top. The preparation process for cappuccino can vary, with options ranging from fully automatic to semi-automatic or even completely manual methods. For detailed instructions on how to prepare a cappuccino, please refer to the specific guidelines provided under the section "Cappuccino making."

— Latte. Latte is another espresso-based drink that includes both milk and milk foam on the surface. It differs from the cappuccino mentioned earlier in a few ways. Firstly, it has a slightly smaller amount of foam. Secondly, it is served in a special tall glass and typically enjoyed by drinking through a straw. Additionally, the volume of a latte can be larger, reaching up to 360 mL. One can also add various syrups to the drink to create unique flavors and taste combinations.

— Latte macchiato. A drink that has a similar composition to the latte mentioned earlier. However, it differs in the preparation method. In the case of a latte macchiato, instead of pouring milk into the coffee, the coffee is poured into the milk, but in a specific manner. The milk is first frothed, and then espresso is poured through the foam. This process creates a small mark or speck on the surface of the foam, which is why the drink is called "macchiato" meaning "stained" in Italian. A properly prepared latte macchiato has a layered structure, with the coffee on top and the thicker and cooler milk at the bottom.

— Hot chocolate. In this context, the term can refer to both traditional hot chocolate and a more affordable and easier-to-prepare alternative called cocoa. Traditional hot chocolate is made by melting solid chocolate into hot milk, while cocoa is made using cocoa powder and can be prepared with either milk or water. The specific methods of preparing hot chocolate in various coffee makers may vary, and it is advisable to refer to the specific instructions provided for each machine.

— Hot milk. A separate programme for heating milk — usually up to a temperature of about 65 °C. Milk heated to such a temperature is already perceived as hot, but it does not turn into foam, moreover, it acquires a sweetish taste. Such milk can be used both for preparing various types of coffee (the same cappuccino or latte), and as an separate drink.

— Milk foam. A dedicated program for preparing milk foam is available in coffee makers, particularly in models with automatic and semi-automatic cappuccino preparation (as mentioned below). This feature allows the machine to autonomously draw milk from an external or built-in container, froth it into foam, and dispense it through the spout. This program not only facilitates the creation of traditional cappuccinos but also provides opportunities for experimentation and the development of unique recipes. It enables users to add foam to drinks that may not have originally included it in their recipes, offering enhanced customization options.

— Hot water. A separate programme for heating water — usually up to a temperature of about 90 °C. Such water can be used both for making coffee (primarily Americano, see above), and for brewing various tea — classic, herbal, berry, etc.: for many of these compositions, the temperature of 90 °C is optimal.

Note that not all are listed above, but only the most popular programmes used in modern coffee makers. In addition to them, other recipes may be provided in the design — for example, cold brew, cortado (espresso and hot milk 1 to 1), etc.

— Grinding degree. Choosing the degree of coffee grinding is crucial for achieving the desired strength and consistency of the final coffee. Different types of coffee drinks require varying degrees of grinding. For espresso and related drinks like cappuccino and latte, a fine grind is necessary. Turkish coffee requires an extremely fine grind, almost like "dust." Cream coffee and filter coffee are best with a medium grind, while a coarse grind works well for French press.

— Pre-wetting. One option available in some coffee makers is the ability to pre-moisten the ground coffee with hot water before brewing the drink. This feature allows users to customize the duration of coffee wetting, although there may be exceptions. Pre-wetting plays a crucial role in enhancing the taste and aroma of coffee, resulting in a more intense and flavorful beverage. Automatic coffee makers often include this feature.

— The strength of the drink. Coffee enthusiasts have the option to manually adjust the strength of their beverage. This adjustment can be achieved through various methods, such as changing the coffee-to-water ratio, adjusting the water temperature, or controlling the brewing speed. The number of available settings may vary, ranging from a basic choice between "strong" and "mild" to more advanced options. Regardless of the number of settings, this function allows...individuals to personalize the taste of their coffee according to their preferences, providing additional customization features.

— Drink volume. Coffee makers offer the feature of selecting the desired volume of the final beverage according to individual preferences. Different models may have varying methods for making this choice. Some machines provide fixed settings (20 mL, 35 mL, etc.) from hich users can select their preferred option. Other models allow for manual adjustment of the volume, sometimes even allowing users to gauge it visually. This feature enables users to customize standard programs to their liking and provides opportunities for experimenting with unique recipes.

— Temperature control. Coffee makers offer the ability to regulate the water temperature for brewing coffee. The taste of the final beverage is heavily influenced by this factor. Higher temperatures result in a brighter and more intense flavor, but excessive heating (96 °C and above) can release compounds from the coffee that add bitterness. The optimal brewing temperature is generally considered to be within the range of 92 — 95 °C. However, coffee makers may provide a wider range of temperature adjustments. Some believe that even a difference of just 1 °C can significantly impact the properties of the coffee, making this adjustment essential for those who appreciate the subtle nuances of taste and aroma in their coffee.

— Steam pressure. Coffee makers offer the feature to adjust the steam pressure coming out of the panarello nozzle. This nozzle is used for frothing milk, especially when preparing cappuccino, as well as for heating milk. By modifying the steam outlet pressure, users can control the intensity of the steam and achieve varying foam densities. It also allows them to omit foam altogether if the intention is solely to heat the milk.

— Foam volume / density. For coffee and milk beverage enthusiasts, the ability to adjust the volume and thickness of the foam "cap" is highly useful. This feature is particularly valuable when preparing drinks like cappuccino, latte, and macchiato. The quality of the final beverage is influenced by the quantity and density of the foam. By customizing these parameters, users can tailor the drink to their personal taste preferences.

— Water hardness. Coffee makers offer the capability to adjust the settings based on the hardness of the water being used. Over time, the heating element of the coffee machine accumulates scale and requires regular cleaning or descaling. The rate of scale buildup increases with harder water, necessitating more frequent cleaning. However, the coffee machine evaluates the condition of the heating element not based on the actual scale amount, but by considering the water hardness setting and the duration of operation since the last cleaning. Therefore, it is crucial to correctly set the water hardness settings to receive timely notifications for descaling. Coffee machines equipped with this feature often include a water hardness indicator with four settings: very soft, soft, hard, and very hard.

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.

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.
