Operating principle of a capsule coffee maker
In a regular coffee machine you need to pour ground coffee or beans.
The capsule is loaded inside the machine, where it is pierced through by a needle. Boiling water passes through the hole in the capsule, brewing the drink. Coffee is packaged in an aluminum or plastic box, which is filled with inert gas. This allows you to preserve the taste of the drink for a long time.
pros
- price. Capsule machines are much cheaper than any other coffee makers;
- high quality coffee. High demands are placed on the contents of the capsules, and the manufacturing process is carefully controlled. You can be sure that when you load a capsule into the machine, you will receive an excellent drink;
- ease of operation. To brew coffee, you need to press 1-2 buttons. It’s difficult to make bad coffee here - in just one minute you can get a three-layer latte with strong foam;
- large selection of drinks. Many types of coffee, cocoa and even tea are produced in capsules.
Minuses
- high cost of capsules. They are mostly disposable and quite expensive;
- binding to one type of capsules. The choice of drinks is limited to 15-26 standard recipes.
How a capsule coffee machine works
The ability to try a new drink depends mainly on the manufacturer of the capsules. And it is advisable to buy coffee in advance - they are sold mainly in large or specialized stores.
On a note! You can save a lot if you buy empty capsules. They can be topped with coffee to suit your taste. There are disposable ones with foil lids (Capsul'in and C&M) or reusable ones that need to be washed after use (manufacturers Coffeeduck, Emohome).
Compatibility of capsules and coffee machines
Criteria for choosing a coffee machine
- Water tank volume. Here you need to build on your needs. For a family of two people, a coffee maker of 0.5-0.8 liters is enough. For a large family or office, it is advisable to choose options with a much larger volume.
- Case material. Most coffee machines are made entirely of plastic or with metal inserts. Premium category devices can be made entirely of metal.
- Availability of a cappuccino maker. If you plan to make coffee with the addition of fresh milk, it is advisable to choose models with a built-in cappuccino maker.
- Type of capsules. This is the most important criterion, since regular expenses for coffee and the choice of drink varieties will depend on the type of capsules.
Advantages of capsule coffee makers over other coffee makers
Important! The quality of operation of a capsule coffee machine is not affected in any way by the operating pressure. This parameter is important for conventional coffee makers, while capsule coffee makers are designed for their own pressure. For example, Nespresso has 19 bars, Dolce Gusto has 15, Tassimo has 3.3.

Video overview of the main characteristics in the video below:
Results
Nespresso De longhi Essenza EN97 W is a typical representative of the initial class of capsule systems. In this case, the Nespresso capsule system is the most honored and famous. This is a representative of a large family, whose ancestors were the founders of the now popular approach to brewing coffee: “put in a capsule, press a button - ready.”
Road capsule machines
Separately, it is worth highlighting compact coffee machines. This is currently an unpopular product and there are only two models in the rating.
No. 2. Sippy Espresso Maker

Wacaco Minipresso NS
Types of coffee capsules
No. 1. Nespresso
Manufacturer: Nestle. Today there are 26 types of capsules, which differ in type, strength of the drink and type of coffee. The range is more than extensive:
- 21 types of classic espresso;
- 5 types of lungo coffee.
Most capsules are pure black coffee, a couple are with flavors such as caramel or vanilla.
They are aluminum capsules with 7 grams of coffee. This is 2 grams less than what is usually used to make espresso, but the lack of weight is fully compensated by the highest quality of the drink.
To prepare drinks with foam, you need to purchase a cappuccino machine - a device for frothing milk. Many machines that run on Nespresso capsules come with a cappuccino maker.
Types of Nespresso capsules
These types of capsules are mainly used by Krups, Delonghi and KitchenAid brands. The cost of Nespresso coffee machines varies from 5,000 to 48,000 rubles.
You can save money or diversify your menu if you buy non-original capsules. For example, many companies produce capsules for such machines - Julius Meinl, Starbucks, Bialetti, Carraro, L'Or, Caffesso, Vergnano, Single Cup Coffee, Movenpick, Brill Cafe, Coffee Joy, RIOBA. The cost of a set of capsules is 200-500 rubles.
pros
- a large selection of drinks from Nespresso and alternative manufacturers;
- the ability to use reusable capsules to refill your own coffee;
- a wide range of high-quality and reliable coffee machines.
Minuses
- high cost of capsules;
- You can buy such capsules only in specialized stores;
- To make coffee with milk you need to buy additional equipment.
nespresso capsules
No. 2. Dolce gusto
Manufacturer: Nescafe. Capsules and coffee machines that use them cost much less than Nespresso.
The assortment includes 26 types of drinks:
- 14 types of black coffee;
- 7 types of coffee with milk;
- 4 chocolate drinks;
- milk tea with spices.
On a note! There is even less coffee in one capsule than even in Nespresso - only 6 grams.
Variety of flavors Dolce gusto
The advantage and at the same time the disadvantage of these capsules is that the milk comes in a separate capsule. This is convenient because you don’t have to froth the milk yourself. The downside is that the cost of coffee with milk is twice as high - since you need to spend two capsules to prepare them.
This type of capsule is used only by Krups coffee machines.
pros
- a wide variety of drinks;
- relatively low cost of capsules and coffee machines;
- the ability to prepare drinks with milk foam without additional equipment.
Minuses
- the quality of coffee machines is slightly worse than in the previous version;
- double price for drinks with milk;
- “underweight” of black coffee.
Some of the drinks are prepared on the basis of instant coffee and may contain various additives such as emulsifiers. These are mocha, iced cappuccino, café au lait and cortado.
Dolce gusto capsules
No. 3. Tassimo
Manufacturer: Bosch. The capsules are filled with Jakobs Monarch coffee. Today, 15 flavors are produced. There are options for black coffee, tea, cafe au lait and cocoa. Coffee with milk will cost twice as much as black coffee, since you need to use two capsules - an espresso capsule and a milk capsule.
The capsules are larger than those of previous manufacturers and are disc-shaped. One capsule contains 9 grams of coffee.
The machines designed for Tassimo capsules operate at lower pressure - all 3.3 bar. Their contents are not as tightly compressed as in Nespresso or Dolce capsules and there is simply no need for powerful pressure.
Tassimo capsules
Coffee machines are inexpensive, the cost of the most budget models starts from 3,000 rubles. But the savings on the device are offset by the high cost of the capsules. Coffee makers that cost above average have a built-in water filter and a larger water tank capacity.
pros
- intelligent coffee preparation process. The built-in scanner reads information about the method of preparation of each individual capsule - water temperature, volume, cooking duration;
- 9 grams of coffee are used to prepare one serving;
- large selection of available coffee machines;
- the ability to prepare cappuccino, cocoa and even tea without the use of additional equipment.
Minuses
- black coffee only 7 types;
- The barcode scanner that reads the prescription from the capsule must be wiped regularly;
- double price for latte and cappuccino;
- Café au Lait capsules are filled with instant coffee;
- from 2021, powdered milk is used instead of sterilized concentrate;
- coffee machines are quite sensitive to water quality and are inferior in service life to previous options.
Tassimo capsules
No. 4. Lavazza
Can only be used in coffee machines of the same brand. The result is a delicious Italian drink with thick coffee foam.
The capsules are made of food-grade plastic. Filling - 7.5 g.
Lavazza coffee flavors
There are about ten types of coffee, mostly espresso. The cost of capsules is practically no different from Tassimo.
pros
- high-quality coffee machines;
- high taste qualities of coffee.
Minuses
- the cost of coffee machines is much higher than that of models from other manufacturers with similar characteristics.
Lavazza capsules
Caffitaly S06
Caffitaly is a company that not only actively promotes its brand on the market by producing coffee machines. If we talk about the brand's popularity, it is famous for its widespread capsules for the same coffee machines.
It should be noted that some manufacturers accommodate the consumer and add to their capsules the ability to load regular coffee into them and prepare it in a coffee machine. This trick is not possible with Caffitaly capsules - the capsule is disposable.
It will be quite easy to notice the Caffitaly S06 on a store shelf and distinguish it from other coffee machines - the design of the coffee maker is very original.
Externally, the device resembles a shell (hence the second name of the coffee machine – Nautilus) . Several color schemes enhance the effect of originality. So this device can become, at a minimum, an original design solution for the kitchen.
Options
Technical parameters of the device:
- height – 33 cm;
- width – 22 cm;
- depth – 29 cm;
- weight – 5 kg;
- case material – plastic;
- water tank volume – 1.2 l.

- adjusting the portion of hot water;
- quick steam
Peculiarities
The coffee machine has a fairly standard set of functions for its class. The only nice feature is the height-adjustable drip tray.
The main feature is the Panarello milk foam attachment. To use it, some skills are required (coffee lovers note that the foam prepared with Panarello is especially airy).
Advantages
The advantages of the coffee maker include:
- original design;
- high-quality implementation of all declared standard functions;
- widespread availability of Caffitaly capsules.
You can purchase capsules for making Caffitaly coffee in almost any specialty store.
Flaws

- lack of an anti-drip system;
- lack of waste level indication;
- lack of coffee level indication;

Short video instruction for this coffee machine:
Features of capsule machine care
Although capsule machines do not need to be washed after each use, they still require regular care.
Once every couple of weeks or two, depending on how often you use it, you need to wipe the working parts of the coffee maker - the container for loading the capsule, the drip tray.
Once a month, it is necessary to rinse the water tank and the compartment where used capsules are stored (if the model provides this).
Scale should be removed 3-4 times a year. Some machines already come with a built-in self-cleaning function or at least a scale level indicator. To wash, you need to buy a special liquid - a decalcifier. The product must be selected depending on the model of the machine. This could be a liquid that needs to be added to the water container or rinse capsule.
If you plan to leave or simply not use the machine for a long time, it is better to drain the remaining water from the tank so that it does not stagnate.

Bottom line. Which system is better?
If we formally add up the number of advantages, then the Tassimo system will win. It will also be a leader if you approach the purchase primarily for reasons of economy. The most accessible cars and capsules are about her. But the lack of choice of flavors and the transition to powdered milk by 2021 could ruin everything. I can recommend this system, and in the most affordable version of the coffee machine, in only one case. You have already drunk coffee from under it and have decided that you are completely satisfied with the taste. Then an excellent option that fully reveals the advantages of the system - efficiency (among capsule machines) - Bosch Tassimo Vivy II.
Dolce Gusto , as for me, is an ambiguous system. Yes, it is inexpensive, but there are no problems with the choice of flavors described above. But quality. Powdered milk and a decent chance of a coffee machine failure - if you take a serious approach to coffee drinking, it would be a sin to advise this. Although there is one win-win area of application - getting to know the capsule approach to preparing this invigorating drink. If you are satisfied with everything, then you are ready to move on to the class leaders. If not, then the best models of capsule machines will not suit you. As such an option “for beginners,” I advise you to consider the Dolce Gusto Piccolo coffee machine.
And I would name the Nespresso and Cremesso systems as leaders in capsule technology. I propose to make a choice between them based on the availability of capsules. If you have the opportunity to get Delica capsules without any problems, then I advise you to opt for the Cremesso system. Still, the taste of her coffee is more precise, noble and best meets the expectations of the picky public. And the appearance... judge for yourself: Cremesso Compact Automatic. As of 2021, Cremesso in Russia can be said to no longer exist, alas.
If there is a shortage of Cremesso capsules in nearby stores (which is most likely the case), but in addition to Nespresso there are also various analogues, then feel free to take the “default system option”, for example, the Delonghi Nespresso EN80 coffee machine or the baby EN85. With the variety of capsules and the quality of the drink in the cup, you can't go wrong. As for the more expensive Nespresso coffee machines, functionally they will all be complete analogues of these two, the cheapest ones. The exception is models with an automatic cappuccino maker, there are several of them, but the most optimal, in my opinion, is Nespresso Lattissima.
The table below shows the best prices for coffee machines for each of the capsule systems described above. I update these special offers once or twice a week, finding the best options (more promotions here).

Addition for 2021:
Above I described all the main capsule systems that are widespread on the Russian market. Until 2015, there were basically no other options. But in 2021, new representatives of the capsule “class” began to appear “on the shelves,” albeit extremely rarely. Finding them for sale outside of online stores is almost impossible, but I couldn’t pass by a topic that was close to me and not study for beginners. Therefore, I had to write the second part about such capsule brands as Squesito, Сaffitaly, DI MAESTRI, Bialetti, Lavazza, and Paulig - you are welcome to be curious.
PS If you are going to drink more than a couple of cups of coffee a day, it is better to immediately consider another type of coffee machine - classic grain machines, for example, Saeco or Delonghi.
Yes, the machines themselves, especially at first glance, seem significantly more expensive than capsule ones, but you’ll make up the difference in coffee in just 1,000 cups. That is, in half a year - a year, and “office workers” are even faster. Don’t believe that there are good inexpensive machines? I compiled this rating especially for you.
PPS Do you want to enjoy a lush cappuccino or a delicate latte, made from normal milk and not from concentrate? The whole range of options is in my review of coffee makers and cappuccino machines.
