What does a 15 bar pump mean on an espresso machine?
These machines often have a pump capable of generating 15 bars of maximum pressure, but they operate at a lower pressure during the extraction process. The higher pressure rating is meant to ensure that the machine can consistently reach and maintain the optimal nine bars needed for proper extraction. Many machines advertise 15–20 bar pumps, but more pressure doesn’t necessarily mean better espresso; excessively high pressures can lead to uneven flow through the coffee, which results in poor-tasting shots. Often, these numbers indicate the maximum pressure, not the pressure realistically achieved during brewing.When you see a 15-bar vs 20-bar espresso machine, the rating refers to the pump’s maximum pressure capacity, not the brewing pressure. High bar ratings ensure consistent water flow, but brewing at exactly 9 bars is optimal for rich, balanced espresso.Is a 15-bar machine better than 9-bar? Espresso is defined at around 9 bars of pressure. Some machines advertise 15–20 bar pumps, but that figure refers to maximum pump output, not the pressure used for brewing. The best espresso comes from a stable 9 bar; anything higher doesn’t improve flavour.The industry standard of 9 bars has been refined over decades because it produces a balanced extraction, highlighting the best flavors in the coffee. However, lever machines have always operated at slightly higher peak pressures, which taper off during extraction.Optimal Pressure for Espresso The generally accepted standard for brewing espresso is 9 bars of pressure. This pressure level is ideal for extracting the right balance of flavors and creating a rich, creamy crema. However, many consumer espresso machines are marketed with pressure ratings of 15 bars or more.
What does 15 bar pump mean?
When you see a 15-bar vs 20-bar espresso machine, the rating refers to the pump’s maximum pressure capacity, not the brewing pressure. High bar ratings ensure consistent water flow, but brewing at exactly 9 bars is optimal for rich, balanced espresso. The ideal level of BAR passing through your coffee grounds should be around 7-11 BARs of pressure, though some espresso machines will be able to hit higher BAR.While 9 bars is ideal, good espresso can be made within a range of 7 to 11 bars. Some modern machines allow pressure profiling, where pressure changes during brewing. This flexibility can help baristas fine-tune their extractions for different coffee beans and desired flavor profiles.For example, we should aim to extract 36g of liquid espresso from the 18g of ground coffee in 30 seconds, giving us our target ratio of 1:2. Don’t be afraid to try different coffees or big changes in your ratio style, but when you find a coffee you like, stick with it for some time!Serving Size. Most standard espresso cups are designed so that they can serve a single shot of espresso with an average serving size of 30ml, and double shot of espresso, with an average serving size of 60ml.
What does 15 bar mean on a coffee maker?

What is the best bar level for espresso?
While 9 bars is ideal, good espresso can be made within a range of 7 to 11 bars. Some modern machines allow pressure profiling, where pressure changes during brewing.

This flexibility can help baristas fine-tune their extractions for different coffee beans and desired flavor profiles.The ideal level of BAR passing through your coffee grounds should be around 7-11 BARs of pressure, though some espresso machines will be able to hit higher BAR.To achieve an absolutely delicious espresso, the water heated optimally between 88 and 94 degrees Celsius should flow through the coffee grounds at a pressure of 9 bar over the span of 30 seconds. Many models of coffee machines come with their pressure pre-set to these standards, including portafilter machines.
Is 15 or 20 bar better for espresso?
Espresso is defined at around 9 bars of pressure. Some machines advertise 15–20 bar pumps, but that figure refers to maximum pump output, not the pressure used for brewing. The best espresso comes from a stable 9 bar; anything higher doesn’t improve flavour. The ideal level of BAR passing through your coffee grounds should be around 7-11 BARs of pressure, though some espresso machines will be able to hit higher BAR.Reach for the 9 bar To sound some clear and concise answer to the article’s title – pressure ofnine barrels is really the ideal choice. If you have the opportunity to play around with the pressure of the coffee machine, then (as mentioned) even values between 7-11 bars may besuitable for you .
Is 9 bar or 15 bar better?
Pressure (9 bar, not 15 or 20) Many machines advertise 15–20 bar pumps, but more pressure doesn’t necessarily mean better espresso; excessively high pressures can lead to uneven flow through the coffee, which results in poor-tasting shots. Too much more than 9-bar can result in a burnt-tasting espresso, while too less than 9-bar will produce a weak and overly bright shot. When pulling an espresso shot, the barista should always start by achieving the recommended 9-bar of pressure.If the coffee is extracted too quickly through the group handle it will have very little flavour and body. The espresso will look watery and have little to no crema. The problem is usually that the grind is too coarse. Adjust your grinder or get your coffee roaster to adjust it for you.What happens if espresso pressure is too low? Low espresso pressure, typically below 7 bars, results in under-extraction. This causes the shot to flow too quickly, often in less than 20 seconds. You’ll notice a thin, watery texture and little to no crema.A fine grind is required to achieve espresso’s rich, bold flavour. Adjusting your grind size slightly can help you dial in a shot to perfection, as finer adjustments can impact the taste.
