In fact, 9 bars is exactly the pressure you’ll find in most commercial level machines, such as the ones in coffee shops. This is all the pressure needed to extract the perfect beverage, and it has remained that way for as long as espresso machines have existed.
Simply put, the sweet spot for extracting espresso in terms of pressure is 9 bars. How Many Bars Are Needed for a Good Espresso?
Of course, this leads us right back to where we started, which is with the question, “how many bars of pressure for espresso is enough, and why are there so many different options?” It’s used as the industry standard, and it’s why you’ll notice that espresso shots from multiple coffee shops, coffee shop chains, and even home machines taste the same. Our predecessors in the industry played with these two variables until they found a sweet spot where everything about the beverage is just right. However, the increased extraction time will output a stronger beverage. As such, you’ll be reducing the strength of the beverage output by lowering the pressure. However, you’ll also be reducing the strength of the coffee at the same time by reducing the extraction time.Ĭonversely, reducing the pressure leads to an increase in the extraction time. In short, you’ll be increasing the strength of the coffee by adding pressure. If you increase the pressure for brewing, you’ll likely reduce the brewing/extraction time in the process. If you reduce the extraction time, the coffee will likely be weaker. If you increase it, you provide more time for extraction, meaning the beverage will be stronger. With extraction time, it generally follows the same trend as the pressure. The other factors we mentioned also come into play. Does this mean you should always go for the highest number of bars you can find in a coffee machine? No. If you were to experiment with different pressure settings, you’d quickly notice that higher pressure often equals stronger coffee, provided that all other factors remain constant. Other factors may also come into play when brewing espresso, but the pressure is one of the main ones you can control. How Does Pressure Affect the Quality of Espresso?Įspresso seemingly has a long history of trial and error, and with it, drinkers of the beverage have noticed that it will taste different depending on the pressure used. So how does pressure affect the quality of espresso brewed? Find out below. With coffee, the pressure exerted affects the outcome of the beverage, which is why most manufacturers and enthusiasts make such a fuss about it. As for pressure in general, it’s defined as the amount of force exerted on a substance. One bar is exactly equal to 100 000 Pa.ĭescribes the bar as a unit of pressure, and it’s equivalent to 100,000 pascals. The bar is commonly used in the industry and in the meteorology. Trusted Source What is Bar – Unit of Pressure - Definition The bar is a metric unit of pressure.
After that, the espresso machine will push boiling water through the portafilter to extract the beverage, and this is where the bars of pressure come in. Typically, it will include grinding the beans, tamping them down into a portafilter, and then attaching the portafilter to the machine. After all, making any coffee beverage does involve chemical reactions. Making espresso is more of a science than an art. As such, we delve into the significance of pressure, so the next time you’re in the store pitting the 9-bar vs the 15-bar espresso makers against each other, you know which one to pick. So is it a marketing gimmick? Does the pressure really matter? How many bars of pressure for espresso is enough? Most newbies to the espresso world are likely to have some of these questions in their minds if they’re really serious about getting the best coffee maker for their needs.Įven some coffee enthusiasts may be unfamiliar with the effects of bar pressure despite having multiple run-ins with home and office espresso machines. Often you’ll see an espresso device being described as a 9-bar, 15-bar, or even a 19-bar machine. If you’re in the market for a beginner espresso machine or even any other category of espresso machine in general, you’ll have noticed that the bar pressure rating is something that’s included in the product description for most models.
