Sick and tired of going to the cafe to get your favourite coffee? For the coffee addicts out there, an espresso machine is the best way to go. Buying your own espresso machine(barista) can be a pretty confusing job. To guide you to choose the most suitable machine, you need to see some aspects of a typical espresso machines.
Before that, you need to know your specs
What do you need it for? Personal use or commercial. About the effort in making the coffee-you want an easy process for a quick cup of cappuccino or are you willing to spare some time to make the brew. Quality of the machine-the better the quality the more it will cost. But a well invested good quality machine is always better than a cheap one which might need constant repair and maintenance.
COST-as we all know, is the most important factor. According to your budget you can choose the level of automation, quality of the machine etc size.
The different aspects of an making a coffee in an espresso machine is the temperature of the water and its pressure and the fineness of ground coffee. The ideal brewing temperature is about 95degree Celsius and the pressure developed over heating of the water (15 atm )or using a purnp is used to push it through the mesh of ground coffee. Tus forms the espresso shot. This is combined with milk in various proportions to make our coffee. Every machine typically has a steam wand which is dipped into the cup. Steam is passed through the wand which heats the milk and forms the froth at the top.
There are different types of espresso machines available in the market today-manual, semi and full automatic, super automatic. From the most to least effort to produce. Then there are also coffee pods.
MANUAL – As the name suggests the whole mechanism should be performed. The pump has to be handled manually. This causes varied quality in the coffee everytime, it is time consuming and tedious, and multiple cups of coffee is very difficult. This is not in use nowadays even though stays a vintage product.
SEMI AND FULL AUTOMATIC-Made automatic with the use of electric pumps. These are affordable too and are hence in popular use nowadays. It is semi or fully automatic in the sense of customisation-full automated has preset temperature and water volumes but we can control when to switch the pump off in case of semi automated allowing us to control the nature of coffee we want to make.
But the price range differs according to the boilers in use
Single boiler–they are the cheapest. They have a single boiler for coffee brewing and milk steaming. Thus we cant do both at the the same time,making it difficult for use on commercial scale as it takes time and effort to make one single coffee one after another.
Single boiler heat exchange–The price of these will be higher than the previous one. But both processes of milk steaming and coffee brewing go hand in hand despite having only one boiler
Double boiler–by far the costliest of the three. They have two boilers,coffee is made faster, and it can be used for a large crowd.But the size of the boilers need not be big enough.So this is just semi commercial.
SUPER AUTOMATIC-the costliest, but you need the least effort.You just push a button and keep a cup, the coffee is made.Best suited for offices and cafes. But u cant change the quality of the coffee.
Then there is COFFEE POD-they are fairly easy to use. But you need capsules of preprepared coffee pods which you put inside.
