A quality espresso machine costs nearly $1,000 (and easily more) but is worth the investment to make delightful espresso every morning. While there are steam machines that retail for over $100, they do not make consistent espresso. The espresso machine brews a shot in 30 seconds by squeezing hot water through the portafilter with nine bars of pressure.Ī quality espresso machine requires several major components to make proper espresso, namely the pump and heating elements. That’s the weight of three espresso machines!Įspresso machines use a 1:2 coffee-to-water ratio, which is much more concentrated than the 1:15 ratio for regular coffee. The coffee grounds are finely ground and tamped down in a portafilter for an espresso machine. Bike tires use 60 psi and car tires use 35 psi. Nine bars of pressure is 245 kilograms (540 pounds) of weight on the espresso puck. Nine bars of pressure equate to 130 pounds per square inch (psi), which is a serious amount of pressure. The water pressure makes the difference in espresso. So, you’re putting nine times the force of gravity into espresso.Įspresso uses specialized espresso machines that generate nine bars of pressure. For context, one bar is Earth’s normal atmosphere it’s what we feel standing outside at sea level. Nine bars is a serious amount of pressure. The pressure makes the difference in espresso. What separates an espresso machine is its ability to generate nine bars of pressure to push water through grounds. How Is Espresso Made?Įspresso’s flavor is far different than other coffee brewing methods. It’s why many people think espresso beans are different than regular coffee beans, but espresso flavor is due to brewing.Įspresso is made with espresso machines. This adds to espresso’s nice flavor profile. Espresso’s fast brew time of 30 seconds doesn’t leave any time to extract the heavy compounds into the espresso shot (very different than the typical four minutes for regular brewed coffee). Bitter flavors come from the heavy compounds in coffee, which take the longest to extract. These components give espresso a thick body.Įspresso is low on bitter flavor due to its fast brew time. The oils are heavy and roll around the mouth and linger. In fact, “espresso” means “expressed” in Italian! Aroma, sweetness, roast, acidity, and unique flavor notes will be very present in espresso.Įspresso machines don’t use a paper filter which allows all the flavor-filled oils to reach the cup. The high ratio of coffee-to-water means the coffee flavors will be more expressed in an espresso. Espresso TasteĮspresso coffee tastes bold (formatting pun intended!). Espresso uses the same beans as other coffee brews, although espresso beans are finely ground and usually dark roast. Espresso machines use high pressure to push water through the coffee grounds, while regular coffee brewing devices use gravity. Espresso versus coffee: the main (and really only) difference between espresso and regular coffee is the brew method.
