Most of MR Coffee Espresso maker are steam driven and only one is pump driven. Personally, I feel that steam driven cannot really produced a good espresso and that this is the reason why I thought only the pump driven machine is good for espresso.

So, what is the definition of espresso? Regardless of the taste or look and feel of this coffee drink, the very basic thing that an espresso must have is crema. But, unfortunately, the steam driven machines from Mr. Coffee are not able to achieve that.

The reason that the coffee brewed does not come with crema is because of the low pressure in extracting them. You need at least 12 bar of pressure to extract a good cup of espresso, but for most of Mr. Coffee steam driven machines, the highest pressure that they can manage is 8 bars.

If you have tried coffee from these machines, you would note that it is not intense but it is bitter. A full bodied espresso is bitter with a tinge of sweetness but these coffees are just plain bitter.

This bitterness has nothing to do with the coffee extraction. It is bitter because it is burnt. As it is steam driven and steam is above boiling point, so when this touches the coffee ground, most of the time it would burn the coffee ground, resulting in the bitter brew.

And because this is using steam technology, the entire brewing process depends heavily on the boiler, which takes a long time to heat up. So, waiting time is another major drawback for the Mr Coffee espresso maker.

Moreover, one boiler has a fixed quantity of steam, so there is a limited number of beverages that you can make before water has to be re-boiled. On average, you can make about 4 espressos and if you need to use the steam to make froth for cappuccino, then you can only brew 2 espressos.

Therefore, this is definitely not a machine meant for parties or large gatherings. The waiting time would no doubt dampen the party mood.

The only pump driven machine from MR Coffee Espresso maker that has enough pressure to extract good espresso would be the ECMP 50. This is one of their latest machines that is pump driven and can extract the coffee ground with up to 15 bar pressure.

This espresso machine also has a thermo block that would shorten your waiting time between each brew and a patented frother that ensures that your cappuccino can be froth properly. In short, it is almost like purchasing a commercial espresso machine.

So, if you do want to buy a MR Coffee Espresso maker, ECMP 50 is the only pump driven machine that is able to extract good quality espresso, the rest of the steam driven machines might not be able to achieve the quality of espresso that you are looking for.
