# Is 15 bar pump pressure good?

## Is 15 bar pump pressure good?

7-15 BAR pressure is typical, and should be considered for those who enjoy great tasting espresso. Top notch coffee makers come with 15 BARs of pressure. 15 BARs may be very useful, giving the machine enough range for an initial kick of 10-11 BARs, from where to drop to 9-10 BARs during brewing.

How many bars of pressure is good for espresso?

What is 1bar unit?

The bar is a metric unit of pressure, but not part of the International System of Units (SI). It is defined as exactly equal to 100,000 Pa (100 kPa), or slightly less than the current average atmospheric pressure on Earth at sea level (approximately 1.013 bar).

## What does 1bar mean?

It is defined as exactly equal to 100,000 Pa (100 kPa), or slightly less than the current average atmospheric pressure on Earth at sea level (approximately 1.013 bar). By the barometric formula, 1 bar is roughly the atmospheric pressure on Earth at an altitude of 111 metres at 15 °C.
