When you consider purchasing a home espresso machine you might think that the choices are very overwhelming. However if you break the machines down into four categories it will make your decision much simpler. The 4 types of home espresso machines are as follows:
1- The old “Moka Maker” or the stovetop model. You have probably seen these simple stove top devices at second hand stores. These were popular after WWII. The best selling shape is an the hour glass model which contains the water in the bottom portion and works somewhat like an old percolator coffee pot.
The biggest issue with this type of espresso maker is that it doesn’t make true espresso with crema but rather produce an over extracted coffee, which is very bitter. Also there is no way to froth milk for making other drinks.
2- The second type is the countertop electric steam espresso machine. This type works somewhat on the same principle as the type 1 to make espresso. It has a heating element in the boiler, which builds pressure as the water nears the boil, forcing low-pressure extraction through the brewing chamber. This again cannot produce an authentic straight espresso.
Most of these espresso makers do however have a steam valve and wand, which with some practice can produce accecptable, frothed milk drinks.
3- Electric piston lever is the third type to consider. This machine is the first home espresso machine that we’ve discussed that despite its antiquated appearance actually makes a great true espresso, crema and all.
This type uses a hand lever to force water, which has been heated by an electric element in the boiler through the ground coffee. Using the hand lever does take a bit a practice to control the extraction. Lever type espresso makers generally have a good milk steaming capability.
4- The last type is the electric pump – pump boiler/pump thermal block.
The pump boiler home espresso machine is similar to a commercial quality machine because it has the water pumped from the reservoir into the boiler, which is heated by an electric element. The espresso is extracted with the aid of the pump. These machines should have two thermostats one for the extraction temp of 195 degrees and the other for the steam of 260 degrees F. The draw back of the pump boiler is that it can take up to 10 min. for the water to warm up.
Pump thermal block espresso makers on the other hand can warm up the water in as fast as 30 seconds because they utilize a radiator type of heating coil so the water is almost instantly heated to the correct temp.
So when it comes to choosing a home espresso machine it is best to upgrade to at least a pump thermal block machine so you can create coffee house quality beverages at home.
One other thing to consider is that today there are some great quality brands of home and commercial espresso machines on the market that will provide many years of great drinks at home. Check out the brands listed on our site.
