Making a good coffee, it is not that easy, just follow these simple rules, but only one can forget nullify all the work undertaken.
First you choose a quality blend. This should be kept in a tightly closed and away from foods that emit strong odors (herbal teas, cheese ,...) because the coffee has the ability to absorb odors, which would alter the flavor.
After mixing, the water is the second factor that determines the success of a coffee (it is said that the water in Naples is the secret of his tazzulella): Use fresh water and possibly low in calcium. Never use hot water to speed up the preparation.
Fill the boiler to the level of safety valve, without exceeding it, otherwise you will have a coffee.
Fill the filter generously, without pressing the coffee powder, forming a small bump (someone, however, has a habit of pressing down the mixture and then make three holes with a match)
Close the pot tightly and place it on a slow fire.
As soon as the coffee begins to go out, raise the lid immediately to prevent the condensation falls into the pot.
Before the coffee is completely released, remove the pot from the fire (in practice, a few seconds before it comes out in the steam left the boiler. Do not worry if some water remains in the boiler, because everything that comes in the final stage can only damage coffee). Never leave boiling coffee on the fire: it burns him, jeopardizing the success.
Enjoy hot coffee, fresh out!.
