Espresso machines produce highly concentrated ,dark and rich brew that are mostly found at the coffee shops. The coffee beans must be finely ground and packed to produce strong coffee which some people prefer to take as shots. Espresso machines can also be used to make milk-based beverages such as lattes and cappuccinos, where milk is heated separately using the machine’s frothing tube which blow steam into the milk whipping it to froth.
Manufacturers have gone to greater lengths in designing and building exceptional espresso makers for home use and also for commercial purposes. Basically, there are two espresso machines which are steam driven espresso machines and pump driven espresso machines. Steam-driven espresso machines worked on steam pressure where steam pressure is used to pump water through the coffee grounds to produce espresso.
I don’t recommend steam-driven espresso machines because they can’t produce enough pressure or temperatures required to produce true espresso,they are just in a position to make very strong cup of coffee.However steam-driven espresso machines are considerably cheaper than pump-driven machines therefore they can be used on the entry level if you are on an extremely tight budget. On the other hand i recommend pump-driven espresso machines which use electric pump that pumps water through the coffee grounds.These machines therefore can produce true espresso.
There are two types of pump-driven machines; Super-automatic espresso machines and semi-automatic espresso machines.The difference between these two units depends on which one better suits yours needs.Semi-automatic espresso machines are perfect for best-quality espresso though it might take a little more time and effort off your schedule. Whereas if you just want a quick cup of great tasting espresso then the super-automatic machine will suit you well since there is no extra effort applied.This machine is suitable for the people on the go or those people who prefer convenience over control.
Overall, I recommend the semi-automatic espresso machine which is all about fine tuning, precise great taste,temperature and body espresso shots that you love especially if you are a “hands on” espresso expert who doesn’t mind a little more effort to ensure high-quality espresso then this is the best option for you.
