Pump driven espresso
A pump driven espresso machine is very important to have if you are a coffee lover.
Steam driven espresso does not really do its job because it only delivers low pressure, as a result, the coffee quality is not that good.
Having at least a pressure of 15 bar coffee pump in a coffee machine, you are assured that the hot water will pass through the coffee beans in a high pressure.
As a result you get the best quality of coffee.
