Making espresso involves pushing hot water through a compact puck of grounds at high pressure, usually at around 9 bar (9 times the atmospheric pressure at sea level).
The espresso machine boiler, while it is at idle, just sitting there and on, is a sealed container. Simplified here, you see the major elements that we are going to discuss. The metal container (the boiler) with some water in it, the heating element submerged in teh water, steam in the upper portion of the boiler, and the pressurestat on top of
I read somewhere that 15 bar is enough and any pressure higher than that doesn't make any difference. The standard pressure is 15 bar for home machines and 9 bar for professional machines! If so, why are there machines with higher pressure (16, 19, 20, 21 bar) and why do these machines cost more money?
Nov 12, 2017· Domestic machines are a lot smaller and cheaper than the professional espresso machines. So while the machine may have 15-bar of pressure at the pump, by the time the water reaches the brew head this is significantly lower. If the machine is setup correctly the brew head pressure will be around the perfect 9-bar mark, regardless of what pressure the pump creates. Some of the more
An espresso machine is a must-have for any coffee aficionado. We've conducted thorough tests and research to find the best espresso machines of 2020.

Piston driven espresso machines use a lever to create BAR pressure. Pump driven machines use modern motor-driven pump provide the force necessary for espresso brewing. Too much pressure is unwarranted. The piston method delivers usually 8 to 10 BAR units of pressure, which in normal language, is 116 to 145 pounds per square inch (psi) of pressure. In 2005, the air-pump driven
Nov 12, 2017· Professional machines are set to brew coffee at 9-bar of pressure, while home or semi-professional machines are often quoted to have around 15-bar. In this article, well explain what espresso bar pressure actually means, and what level you should look for when buying the best coffee machine for you.
For the most part, 7-9 bars of pressure is considered the sweet spot for pump driven espresso machines, which use a pump to force water through the grounds. Pump driven machines, as well as rotary ones, are known to be much better than those that brew using steam, known as steam driven.
Jan 30, 2017· You want to control the flow rate of your espresso by adjusting grind size, not tamping pressure. If tamping pressure is a variable then you need to do it the same every single time. This is, frankly, a ridiculous ask for a human and should be entirely avoided. Luckily, theres an easy way to almost eliminate tamping pressure as a variable.
