- Hi Everyone, What is the definitive size for a single shot of espresso in terms of what the industry recognizes? Every website I do to tells me something different. Some say 1 ounce, 1.5 ounces or 2 ounces. Also, when making espresso based drinks, what is the proper amount in ounces to use? For example, a conventional latte is 1/3 espresso and 2/3 steamed milk so how many ounces should I use. Thanks so much for any information.

How an Espresso Machine Works: What's Really Inside? Note that this gauge registers both the pressure within the boiler (the top arrow), and the extraction pressure (the bottom arrow). Both arrows should be within their green regions. We will typically run the boiler pressure (the pressure of the steam) at 1.5 Bars (see the gauge).

- This is based mainly on my own five years of examining literally thousands of espresso shots, but also on what most modern day espresso literati belive - the ideal extraction time (when heated water touches a bed of coffee) is between 25 and 30 seconds. Under that time, and you end up with sour, underextracted coffee.

What is the minimum pressure the human body can handle? Regarding the first point: Humans are frequently subjected to 8 bars of pressure in hyperbaric medicine, which means that, over a period of time, the human body can go from a pressure of 8 bars to 1 bar, a difference of 7 atmospheres. This happens very slowly. If this were to happen quickly, terrible things happen.

Espresso - The Art Of The Barista The Espresso Process. By forcing hot water through finely ground coffee under approximately 9 atmospheres of pressure, a coffee beverage with great aroma, taste and body is created. Extraction using the espresso method takes place using deionised water at 90-94 degrees Celsius. The contact time between water and coffee varies from 20-30seconds. Approximately 8 grams of finely ground, medium roasted coffee is used per cup. Each espresso shot contains approximately 40ml.
