# What Does 15 Bar Mean In An Espresso Machine?

The hot water pressure that is applied to the grinds is not precisely described by the numbers 19-bar or 15-bar that are assigned to these machines.They instead focus on describing the pressure that is generated by the pump inside of the machine.It is important to note that the hot water will likely need to pass through a few additional components of the coffee maker before it can reach the portafilter.

During the brewing process, the pump of the espresso machine is capable of applying a pressure of up to a maximum of 15 bars. Even though it is the maximum pressure that can be applied, that does not indicate that espresso should be extracted at such a high pressure. The extraction pressure that is recommended is around 8 or 9 bars.

When discussing espresso machines, the term ″15 Bar″ refers to the pressure of the pump.When making espresso, the ideal pressure applied to the coffee grounds is between 8 and 9 bars.Some machines employ high-pressure pumps to compensate for the pressure that is lost between the pump and the group head, as well as to ensure that they function correctly with pressured filter baskets and grind sizes that are bigger than optimum.

## What is a 15-bar pressure pump?

Historically, a bar is the unit of measurement for atmospheric air pressure, and the standard measurement of atmospheric air pressure is established (at sea level) as 1 bar, which is equivalent to 1.47 pounds per square inch (psi).It can be summed up like that.When you hear that a device has a pressure of 15 bars, what the manufacturer is really saying is that the pump generates a pressure equal to 15 times 14.7 psi.
