The Different Types Of Espresso Coffee Machines
The
espresso machine has been with us for over a hundred years and in that time, the concept of forcing almost boiling water through a small amount of finely
ground coffee remains unchanged. However the way the water is pressurised in
espresso machines has seen its fair share of advances over the years. These days there are four main types of
espresso coffee machines, each of which we'll have a closer look at:
Steam Driven
The first espresso machines used steam pressure to force the hot water through the ground coffee. Having no moving parts these were easy to manufacture and the method still remains popular today. The classic Moka-Pot espresso maker uses the same method as these early espresso makers, however in this day and age they are not considered to be bona fide espresso machines as their design is too simplistic. However simplicity is at the heart of the stream driven espresso maker as this is its beauty. The steam driven coffee maker need not be more complex than it already is in order to make great coffee every time.
Piston Driven
The Piston driven coffee machine was developed in 1945 in Italy by Achillo Gaggia, the founder of the famous Gaggia brand. The piston driven espresso maker does not rely on steam pressure to force the hot water through the coffee, instead the force is delivered via a hand driven piston which provides the pressure to force the hot water through the coffee grounds. Piston driven espresso coffee machines are the most 'hands on' coffee makers and are a popular device for many cafe bars and bistros as pulling a shot is a bit like pulling a pint.
Pump Driven
In 1961 the piston driven machine was developed further and this resulted in the pump driven machine. This replaced the hand pump with and electric pump and has since become the most popular design in coffee bars as it delivers shots of espresso quickly and with little effort from the barista. Since their conception in the early sixties a further 3 variations have emerged which incorporate and separate the frothing arm by giving it a second boiler to enable two temperatures of water to be attained; boiling for the frothing arm and 90-95 degrees for the coffee to avoid scalding.
Air-pump Driven
The most recent addition to the espresso machine family is the air pump machine designed in 2007. This has been designed to make the perfect espresso whilst on the move and if your pockets are big enough, this pocket-sized espresso maker is ideal for walking, fishing or cycling. The hot water is provided by a kettle or flask and the pressure is provided by a hand pump which works like a bicycle pump. This device also uses coffee pods rather loose ground coffee, however for such a compact espresso machine designed for coffee lover on the move, it certainly packs a punch.

How do you make specialty coffee drinks?
I have a very good coffee and espresso machine. Since the most complicated thing I know how to make with it is a cappuccino (which tastes very good), I was wondering if anyone knew how to make more complicated drinks that you might find at coffee houses. I assume they really aren't that hard to make, its just that I can't seem to get the proportions right...
Say, a mocha, iced coffee drinks, and any other recipe you might know. Thanks!
