On closer inspection it becomes apparent that this espresso maker has two parts. If one separates the two halves one gets an insight [pardon the pun] into the inside of the espresso coffee maker.

Basically one has to carefully fill the bottom half with water. It acts as the water reservoir. It also has a steam release valve which will ensure that the buildup of steam will never reach dangerous levels.

Has the water in the reservoir begins to heat it expands which makes the space available even smaller. As boiling point is reached and steam is generated it becomes a dynamic necessity for the steam to go somewhere.

Before it breaches the release valve it will choose a path of lesser resistance. That will be through the funnel filter which has the coffee grounds in it.

As the steam forces its way through the coffee grounds it rises up the chimney into the top chamber where condensation takes place and a fine espresso is formed.

As soon as the gurgling noise develops it is advisable to move the espresso maker off the heat. As soon as the percolation process is complete, the stove top espresso is ready.

Of course if you make a cappuccino subsequently then this appliance becomes a stove top cappuccino maker.

It is important for people to know that this stovetop espresso maker does not necessarily have any automatic switch off mechanisms to prevent the water in the reservoir boiling away.

The trick is to remove the stove top espresso maker from the heat before the water has boiled off. Once the espresso coffee maker has cooled off it needs to be taken apart and cleaned very carefully. If you look after your espresso maker it will look after you.
