A "separate" version of the automatic espresso machine. This allows for greater control, particularly over the amount of ground coffee and its tamping.
When mastered properly and accompanied by a quality grinder, this is one of the best ways to obtain an espresso, with concentrated aromas and a creamy texture.

Préparation

~ Be sure to clean and descale your machine according to your manufacturer's recommendations. The same coffee served from a dirty machine will taste radically different.
~ Experiment with grind settings to find the right one for your coffee.
~ If you like a long coffee in the morning, do not run the hot water through your coffee for more than 30 seconds, instead topping it up with hot water (the hot water nozzle will be perfectly suitable). This will help avoid the bitter aromas typical of a coffee "tired" by too much extraction.
~ If you're unsure how to measure your water, try the ratio 2g of water to 1g of coffee. This is the one we commonly use at Celsius.
~ A good indicator of the quality of your extraction is the flow rate. To put it simply, we consider that the coffee stream should be the stage just above the drip. We can also take a range of extraction times: between 20 and 35 seconds including the pre-infusion.
