The difference between the head of coffee machine E61 and other heads-the difference between mocha pot and coffee maker

Sometimes those who encounter half a bottle of water will say that this term is out of date, and now the best semi-automatic coffee machine is variable pressure.

Indeed, since 2004, the real variable pressure coffee machine has been born, gradually spread all over the world, and began to enter China in recent years.

But the pressure swing coffee machine is not random, its pressure control requirements are far greater than the traditional semi-automatic Italian coffee machine, coupled with the price of more than a hundred thousand is not affordable to the average family.

To quote the explanation of Brother Bird, the Great Coffee God, "how to understand the variable pressure technology: to reach the specified pressure value at any time, and to be stable, and to remain unchanged after changing to the specified pressure value again, is the real variable pressure."

Since we can't afford the Tuhao coffee machine, we should return to the traditional espresso machine and return to espresso's golden rule of "extracting 1 ounce (30ml) of espresso (espresso) in 25-30 seconds at 90-92 degrees Celsius under 9bar pressure."

Although this golden rule is still controversial in professional coffee forums in recent years, 9bar pressure is basically not controversial, so a bunch of coffee machines boasting 15bar or higher actually refer to the most high pressure of the coffee machine, which is of little significance, and is generally used to fool newcomers. Stable pressure and stable temperature are the criteria for measuring Italian coffee machines.

Most of the semi-automatic machines are consciousness thickeners. This kind of machine is called semi-automatic because it requires you to grind the coffee beans, then put the ground coffee powder into the filter and flatten it with a powder hammer, and finally put it into the consciousness concentrator for extraction. The extracted coffee is esp (consciousness concentrate) and what we often call fancy coffee is made with this as the raw liquid with different proportions of milk or other things.

In the use of semi-automatic coffee machine, there must be a similar grade of electric bean grinder, hand grinder is not too rough will reduce the service life of the coffee machine.

And the fully automatic coffee machine generally does not need a bean grinder, is automatic grinding automatic extraction, if you want to ensure the quality of esp automatic coffee machine generally higher prices (such as Yuri), the current automatic bean grinder can even directly generate fancy coffee, such as you a little cappuccino in the console, as long as you add milk to the container of the coffee machine can be automatically generated. But it makes it much less fun to make coffee.
