Geyser coffee maker: what is it and how to prepare coffee in it

Perhaps the first question that will puzzle a man who has a geyser coffee machine in his house is how to make coffee. But because of the complexity of the device, it is located at the very bottom of the hierarchy of coffee machines. Easier to design only Turks, but because of the nuances in the operation of the Turks, it will be even easier to work with a geyser coffee machine!

Principle of operation

In fact, a geyser coffee machine is still the same filtration of hot water through ground grain, just the opposite. If you used a drip machine or even ground coffee in the filter-boxes, which are installed on the cup, you know how it works. Just water passes through the filter not from top to bottom, but vice versa.

Why so sophisticated? Perhaps, when choosing a coffee maker, you saw that the owners of the drip machines complain about an insufficiently saturated, watery taste. And blame for this need to gravity: under its action, water passes too quickly through the coffee filter, not having time to absorb the taste and aroma. As early as the 30s, coffee connoisseurs decided that it was time to change something: for example, the direction of the passage of water through the filter. Technology was patented by Alfonso Bialetti, who opened the company for the production of the most popular geyser coffee makers at the moment. So what did he think of?

The principle of operation of a geyser coffee machine is a little more complicated than a dropper, for a person far from physics: is it true how to make water flow in the opposite direction?

1. Take three containers: one at the bottom for water, just above the other for ground coffee and another for the finished drink at the top.
2. We connect the filter capacity with tubes with the lower and upper vessels.
3. Now heat the water in the lower vessel, causing it to convert to steam.
4. Steam, due to lack of volume, will start to press on the water, forcing it to search for ways of retreat. They will be the tube to the filter.
5. The more steam will be formed, the higher it will push the water through the tube: first it will pass through the filter, then it will rise above the tube and splash into the upper container.

It is important that the rate at which water rises under the steam pressure is lower than that with which it flows through the filter under the influence of gravity, which means it will have more time to absorb the taste and aroma.

By the way

The great advantage of geysers in front of the Turks is that you can not practically follow the process of making coffee.

It seems to be more or less clear how the system works, but what is required to make coffee from the person himself?

How to make coffee?

Now that you know what it is, a geyser coffee machine seems very simple to use: it filled the water, filled up the coffee - and wait until the laws of physics have done their job. In part, this is true: many people buy geysers in addition to the Turks just because they are easier and faster to manage.

• Fill the cold water in the lower container to the mark. There is no more sense to pour: excess water, turning into steam, will leave through the emergency exit valve of the steam, and at the output you will still get the same volume of the drink. But less pouring is not recommended: the pressure that your model is designed for, may not form, which will affect the brewing process. And remember that the final result depends on the quality of the water.
• In the filter, pour in coarse or medium grind coffee: fine grinding will greatly impede the passage of water through the filter, and also with a high probability will provide a deposit in the upper container. For the same reason, ramming any grinding coffee in the filter is a bad idea. Naturally, coffee is recommended to grind directly before cooking, but it depends on the degree of your coffee gourmandy.
• Place the coffee maker on the fire: it should be medium at the beginning and slow in the middle of the process, so as not to delay cooking, but also not to overheat the coffee. When the finished drink begins to pour into the top tank, you can generally remove the coffee maker from the plate: so you will avoid the taste of burnt and extra bitterness in taste.

Important!

The geyser coffee machine does not provide for the pouring of other liquids other than water, and the filling of other dry components other than coffee. Experience shows that experiments of such a plan do not lead to breakdown, but they can not get any tasty coffee. Milk and sugar is better to add after cooking, although a pinch of spices to the ground coffee can still be added.

There are not so many fine details in working with such coffee makers, and all of them will come to you in the course of operation: somewhere earlier remove from the fire or cool under the water stream the lower capacity, in some situations change the grinding, well and somewhere to experimentwith the amount of water and coffee.

Pros and Cons of

You just can not understand whether a geyser coffee maker is right for you or not? Then answer a few questions.

• Do you like strong coffee? If so, it is better not to change the Turk, because such a strong in the geyser make it difficult.
• Are you used to making coffee with sugar? Caramel taste is obtained when cooking, in our case, only espresso will be cooked, and only then will variations be created on its basis.
• Do you want to save money? The simplest geysers can be found for 500-600 rubles, but it is better to take a coffee maker a bit more quality.
• Are you afraid to break the machine? It is difficult to imagine that something will go wrong in this system. If you have never broken an ordinary teapot, then everything will be fine.
• Are you tired of the sediment from the Turks? With a geyser in a ready-made drink, you will not see it.
• Are you too lazy to stand by the Turks while coffee is being brewed? With a geyser coffee machine, you can leave without fearing for the cleanliness of the cooker and not greatly sacrificing the quality of the drink.

By the way

To wash a geyser coffee machine is not more difficult than ordinary dishes. In terms of care and maintenance it is extremely convenient!

Which one should I choose?

With a geyser coffee machine, it is not necessary to prepare coffee for gas: there are electric models that can be used as easily as electric kettles. That's only they are from 5 thousand and above, and if so, it is better to overpay and buy a more perfect espresso machine.

Choosing from the usual options, take a closer look at stainless steel if you are looking for the best combination of price and quality. Aluminum models are cheaper and easier, but for most people they are enough to enjoy a delicious coffee.

There are also expensive glass and ceramic variations that will appeal first of all to those who care about how the coffee maker fits into the interior of the kitchen.

Responsible to the choice of the volume of the coffee machine, this is very important. The amount of ready-made drink can vary from 40 to 400 ml, and since it is not recommended to deviate from the amount of water and ground coffee, think twice before taking the coffee maker "with a margin".In this case, it is better to weld the coffee twice, if a friend comes to visit than to drink soft coffee, refilling water and coffee for one cup instead of two.

Important!

When washing an aluminum geyser, do not use metal sponges or abrasive products: you will scratch the protective layer and feel the coffee's taste.

Of course, the Turks remain unchanged classics, but as a more convenient addition to it, the geyser coffee maker has a right to exist. The main thing is to take her choice wisely, follow the recommendations and, of course, feel the process of making the most delicious drink on earth.
