How much is the high pressure coffee machine?



coffee-machine

I heard that the higher the pressure of the coffee machine, the stronger the espresso is, so it tastes better.

Then how much is the high pressure?

If it's low, there's about 1.5 atmospheric pressure
If it's high, there's a 9 atmosphere.
