Espresso Articles

The home espresso maker was invented at the beginning of this century. Home espresso makers are much simpler to use and cheaper than commercial and semi-commercial espresso makers. There are two kinds of machines which are used as home espresso makers: the pump driven types and the steam driven types.

The earliest machine used hot water driven by steam to force through the coffee grounds. The machines later used mechanical advantages like a spring and lever.

Over time, the lever and spring were let go and replaced with electronic mechanical pumps. Its action produces a vacuum and draws water from a reservoir. A head of pressure develops as the water is forced from the other end of the vacuum. This pressure later dumps the water either through a boiler or a thermo-block.

The final product is then forced through a mound of tightly packed grounds. Espresso is the oil, flavor and aromas of the beans.

The stove top espresso machine is perfect for home use. Relatively cheap and easier to use than the other automatic and semi-automatic espresso machines, it forms the perfect option for the ones who have just stepped into the aromatic world of espresso.

Another machine used widely for making espresso is the steam-driven-espresso machine. In the steam driven espresso machine, a boiling chamber is used to heat the water. The steam created forces the water into the bed of the coffee beans.

The stove top espresso machine consists of a basket, a base, a basket screen and a collection chamber. Though it takes a comparatively longer time than automatic espresso makers to prepare espresso in the stove top espresso, the quality and consistency is one of the best.

Other than the stove top espresso machine, the automatic espresso machine is becoming more and more common in households. The espresso they produce is more consistent and the machines do not require as much fine tuning as the other versions of espresso making machines. The automatic espresso machines have a flow meter installed, which cuts the ‘shot’ automatically when the pre-programmed level of water is reached.

There are various kinds of automatic espresso machines available in the market.

Coffee is generally prepared in two ways: espresso and drip brew. Drip brew coffee is prepared by pouring water over coffee which is contained in a filter. Espresso is an Italian coffee beverage prepared by forcing hot water through fine ground coffee beans.

Espresso is strong and has a robust flavor. Espresso coffee differs from the other variety of coffee, drip-brewed coffee, by its thick and concentrated consistency. Espresso is generally served in small amounts without any sweeteners or milk. Espresso should be consumed immediately after preparation, because it is highly reactive with oxygen.

There are various other types of espresso, like cafe latte, cafe mocha and cappuccino. All these can be made with one ‘shot’ of espresso.

An Espresso machine is used to prepare the espresso coffee. The machine forces water at 195 F and 9 bar of pressure through a puck of finely ground coffee. It takes about twenty seconds for 1.5 ounces of espresso to be prepared. The time can be modified by increasing the grinding quality - using finer or coarser coffee. Espresso machines also have steam wands, which is used to froth and steam milk for preparing milk-based espresso beverages like cappuccino and latte.

The espresso machine comes in its true element at the hands of a Barista. There are a many elements on which the quality of espresso depends.

There are various types of Espresso machines available in the market. The various kinds are:

Stove Top Espresso Maker:

The stove top espresso maker is the simplest to use. It is made up of the base, brewing basket, basket screen and the collection chamber. It is small and easily transportable and is one of the main kinds of non-electrical espresso machines.

The coffee is placed in the brewing basket, once the base is filled with cold water. Once the basket screen is placed over the brewing basket, the collection chamber is attached back to the base of the machine, and the machine is placed over a heat source.

Steam Espresso Maker:

Though the steam espresso maker is similar to the stove top, it is a steam unit and works on the pump-power principle. It also has a portafilter, which is a filter holding/coffee dispensing unit.

Piston Driven Espresso Maker:

The piston driven espresso machine is the oldest type of espresso machines. They were first made when espresso was first discovered. The modern espresso maker machine is an upgrade of this retro espresso maker. Invented in 1938, it is used widely in thematic parties or shops.

Pump Driven Espresso Machine:

The pump-driven espresso machine is the most used type of espresso machine commercially. It is a variation/upgrade of the piston driven espresso maker, which has a pump instead of a piston.

Automatic Espresso Machine:

The automatic espresso machine produces a more consistent amount of espresso, as compared to the other types of machines. Water flows into the flowmeter, until it reaches the previously programmed level and then the ‘shot’ is cut.

Super Automatic Espresso Machine:

This machine automatically grinds the coffee. Some machines can adjust the shot temperature and water flow.
