If you're about to purchase a coffee machine, you've probably realized that there are a lot of choices and it's a bit confusing trying to decipher all of the various information available.
We have made this section to help you to understand espresso machines a little bit better in order to make it easier for you to choose the model that would fit your needs.
But before we start discussing different types of machines available on the market, let’s review some basic facts about espresso. A good espresso cup is the result of forcing about 1.5 ounces of hot water through tightly packed, finely ground coffee.
The basic principles are to extract only the best part, using water which is not quite boiling and under a lot of pressure. The "best part" and "not quite boiling" bits are critical to making good coffee by any means, while "a lot of pressure" is a neat trick to manage at the same time.
Machines that can do this all at once were only invented in this century. Most low-end home espresso machines settle for "some" pressure, and cheat on the "not quite boiling" part as well. The price of these machines varies between £40 & £80 but we haven't even considered them because the result is strong but bitter, acidic coffee, nothing like a true espresso. Most machines of this sort are the sub 100.00 machines offered by Siemens, De-Loghi and other " Brands", most are produced in the East and do not contain good quality components. They also produce coffee that visually appears correct but tastes nothing like the real thing.
The two categories of home machines that approach the pressure and temperature requirements are those known as "pump driven" and those that are manual, lever operated machines...
THE PUMP STYLE
In pump driven espresso machines, an electric pump draws water from the reservoir and sends it in a heating chamber where it's heated to an optimum temperature that varies between 186°F & 192°F; it is then forced by pressure of 9 to 15bar, which alters depending on the models, through the packed coffee grounds in the group.
True espresso requires pressure of at least 9 atmospheres to emulsify the oils and to dissolve the gasses that will magically appear as "crema."
Our Verdict:
Good: Gaggia Baby (all models), Gaggia Classic, Ascaso Basic, Ascaso Arc, Isomac Giada
Better: Rancilio Silvia, Rancilio Lucy, Ascaso Dream, Ascaso Steel, Isomac mid range
Best: Elektra Micro Casa, VFA Torino, Rancilio Epoca, Isomac top range models
SUPER AUTOMATICS
Super automatic machines do it all: grind the coffee beans, prepare the coffee and ejects used grounds. With a single press of the button, the entire process takes only about 30 seconds to enjoy delicious espresso. All offer excellent coffee and most of the lower priced units require you to make coffee and froth milk as a separate step. The more expensive machines can automatically produce milk based drinks for you, thereby making the process even more convienient. Gaggia Platinum, SAECO Talea and Jura unit can be further automated by adding a bulk milk frother to the unit and almost giving you the same functionality as the fully automated models (see Accessories).
Our Verdict:
Good: Spidem, De-Longhi
Better: SAECO Odea, Gaggia Syncrony, Quickmill
Best: Jura, Gaggia X2, SAECO Talea, Gaggia Platinum
THE HAND-OPERATED LEVER STYLE
These machines not only make excellent espresso, they are beautiful crafted objects that make a distinctive impression on your kitchen counter. This style of espresso maker employs a piston that is driven by means of manual pressure or a spring-loaded action.
When lifted, the piston pulls water from the reservoir into a small chamber and then forces the water into a filter of ground coffee when the piston is lowered.
A lever style machine is quiet and simple to use, once you've mastered it.
The skilled operator of a lever machine can attain a level of control and excellence over their shot of espresso not possible with any other type of home machine.
Our Verdict:
In this Category there is no such thing as a poor choice as all are very robust and last.
Good: La pavoni Europiccola
Better: Elektra Leva, La Pavoni Professional
Pod or Capsule Machines
There are two types here; one uses the ESE Pod (looks like a teabag) and the other use a capsule system. Whilst both are foolproof in producing a good espresso and being a very convienient way of producing a consistent result. All machines will also froth milk, thus permitting the user to make any kind of drink related to coffee.
The capsule system is brand dependant and of all the various types available, the Gaggia Caffitaly system produces by far the best results. This is due to the fact that these contain 8gr of ground coffee and not 6 gram most common to other makes.
So if you are someone that only has two coffees a day, then the ESE pod Machines or the Caffitaly machines are strongly recommended. The whole of the Gaggia range of semi automatic machines now can be used with ESE pods and La Pavoni has just added this function to their units as well. Rancilio machines need a pod adaptor kit, available as a separate part.
