Modern models have a set of useful options. Stand for warming up cups, the timer of automatic switching-off, the possibility of simultaneous preparation of two cups, and etc. provide additional comfort.
Scum creates serious problems for the espresso machine and can lead to its breakage.
The automatic decalcification function successfully solves this problem. Device automatically removes the scum and is cleaned of the coffee oils.
Modern models are equipped with different modes. For example, pressed ground coffee is pre-wetted with water for flavor improvement.
Most modern models are equipped with a cappuccinatore.
Cappuccino is an analogue of espresso with the addition of milk and milk foam. Milk or cream is whipped with the help of cappuccinatore. A coffee machine can prepare cappuccino in automatic or manual mode. Some devices automatically whip the milk in a separate container. Then, the resulting foam is added to the cup. Manual mode provides for the supply of steam through a separate tube to whip the milk in a special container. Then the foam is added to the cup. Fast steam mode provides an almost instantaneous switching of the device from espresso to cappuccino.
Adjusting the grinding degree is extremely important. Too fine grinding adds bitterness to coffee flavor. Coffee from too coarse grinding is weak and sour. The degree of optimal grinding depends on the humidity, air temperature, grains size and degree of their roasting.
A removable drip tray protects the table from the water during coffee making.
Power is an important characteristic of the model. The speed of coffee making and its strength depends on the power. In addition, these parameters directly depend on each other. Increasing the power provides reduction in cooking time and enhances saturation of coffee taste. In this case water does not have time to absorb the aroma of ground coffee. This factor is important when choosing a model. The power of modern household models is usually from 800 W to 2500 W. The power from 1000 W to 1500 W is considered optimal for home use.
The capacity of a container for coffee beans is also an important parameter. Its optimal importance is determined by the operating mode. The capacity of a container of 300 grams or more ensures its long-term operation in the intensive mode without a break for maintenance. Smaller containers are convenient for home use.
Some commercial models have the ability to connect to water. Such devices are able to independently take the necessary amount of water similar to washing machines. But today, such models are very rare among consumer models because of the high price.
Built-in coffee machines are more expensive, and their range is much smaller.
