Filter coffee machines
let’s start from the beginning, i.e. with the filter coffee machines. The taste of the drink prepared with their help is similar to “Turkish coffee” (ground coffee poured with boiling water), but there is no problem with the grounds, thanks to the use of a filter.
Construction of an overflow coffee machine:
- water tank (with a capacity of 0.3 to 2 l),
- coffee container ,,
- filter – usually disposable, paper or integrated (permanent) – in the form of a mesh, which should be thoroughly washed after each use,
- a jug – most often made of heat-resistant glass or a steel thermos jug – in order to maintain a higher temperature for longer,
- heating plate – maintains the temperature of the coffee.
The filter coffee machines are very easy to use. Just pour the right amount of ground coffee into the filter container and press the button. The coffee machine pours boiling water over it and slowly seeps into the jug at the bottom. This method of brewing means that the drink contains more caffeine than when using an espresso machine.
Advantages of drip coffee makers:
- Low price – quite cheap, and the main cost of their use is inexpensive, paper filters.
- The heating plate, located under the jug, keeps the coffee brewed hot for a long time (in the case of a thermos – up to 4 hours).
- You can make multiple portions of coffee at a time.
- The possibility of preparing not only coffee, but also infusions of tea and herbs.
Disadvantages of drip coffee makers:
- They are for ground coffee, and since coffee made from freshly ground beans is known to be the best, you also need a grinder.
- The process of making coffee is quite laborious (usually requires buying and replacing or cleaning the filter) and long (takes about 10-15 minutes).
- It is not very good for making small amounts of a drink (e.g. one serving).
- Less possibilities for preparing coffee – no function of preparing coffee with milk; only some of them can adjust the strength of the coffee.
- Prepared coffee contains toxins (bitter substances and acids) and has a high caffeine content (almost twice as much as coffee from an espresso machine).
- The lower quality of the coffee drink may not be good enough for the gourmet.
- The most popular producers of filter coffee machines include: De’Longi, Bosh, Siemens, Backstroke, Mentality.
- The simplest form of making pressurized coffee is a coffee machine, also known as a cafeteria or mocha. It is a low-pressure coffee machine and is used to prepare traditional Italian coffee. This drink has a strong, aromatic (sometimes slightly acidic) taste and lacks the cream characteristic of an espresso.
- It consists of a jug, a coffee strainer in the middle and a bottom water container. Coffee makers are usually made of aluminum (cheaper) or steel (more durable and more expensive). They can also be “combined”, for example with a steel bottom and a porcelain coffee pot.
- The preparation of coffee consists in pouring a certain amount of water into the lower container and pouring ground coffee into the strainer. After all 3 parts have been carefully assembled, the device is placed on the stove to boil the water. The pressure created by the resulting steam causes the water to be forced upwards through the coffee. The brewing is collected in the upper tank. You can prepare from 1 to 6 cups of a drink in the coffee maker (one cup is approx. 40 ml), depending on its size.
- Brewing coffee using this method takes 5 to 15 minutes (depending on the size of the machine). The coffee maker is put on low heat. If you have an induction cooker, you need to obtain a device specially adapted to it. There are also electric coffee makers with a heating base. They are often equipped with a timer function that allows you to program the coffee machine to prepare coffee at a selected time. Another interesting feature is the “Mukka Express” coffee maker by the Italian company Bialetti, which is used to prepare cappuccinos.
