The principle of operation of a geyser coffee maker is based on the use of steam under pressure.. After filling the lower compartment of the apparatus with water and placing the coffee maker on the stove (or connecting it to the mains), the water begins to heat up and turns into steam during the boiling process.

I bought a stovetop geyser coffee maker especially for my husband. The main plus is the convenience for those who do a million things at the same time when preparing coffee: unlike the Turks, coffee will not run away. I add spices when brewing coffee, but my favorite is making herbal tea with it. The main thing is that the raw materials for cooking are large, otherwise they will clog.

Good afternoon! I looked at the geyser coffee maker for a long time, bribed the ease of use: poured, poured and go about your business. I bought the simplest, for use on a gas stove. I have been using it for three months, I really like it, the coffee maker is easy to use. I add cardamom to coffee, the taste and aroma is excellent. I also tried to brew wild rose, the infusion turned out to be very rich.

  Geyser models win over ordinary Turks, but they are not much more expensive, a good choice.

By chance, an old Soviet geyser coffee maker fell into the hands. It turns out that this is a very original and convenient way of making coffee. Used on both gas and electric stoves. The only negative is that, compared to the Turk, the taste is not so rich, more watery. Maybe I'm doing something wrong in the brewing technology?
The article is very helpful! Now I know exactly how to take care of this unit so that it lasts longer.

  Perhaps at first it may seem that the taste is a little simpler than in the Turk. But over time, I realized for myself that in the geyser the taste is still more interesting.In general, try adding more coffee.

Four months ago, I got this wonderful Krauff geyser coffee maker. To say that I am happy is to say nothing! Every morning starts with a cup of fragrant, delicious coffee. And despite the fact that my coffee maker friend and I are friends, I had a lot of questions, the answers to which I received after reading this article. Thank you! The discovery for me was that the fire should be minimal, I always put it on the maximum. And one more mistake of mine - I use coffee of varying degrees of grinding in the coffee maker (now, for example, my favorite Illi coffee is medium grinding). But you write that coffee should only be coarsely ground. That is, it is for the correct operation of the coffee maker?

1. Igor He speaks
  
  Rather, the final taste of the drink will depend on the grinding, you can experiment.

I recently started using a geyser coffee maker, bought a few years ago. I really like the result, but I have one detail - a round metal filter with a small stick in the middle, which is not mentioned in the instructions (in the article on the photo about care). How to use it?

1. Igor Zubarev He speaks
  
  Ground coffee is added to it, then it is inserted into the lower part of the coffee maker and then the upper part is twisted.
