Hot water is rapidly forced through the grounds, by the extremely high pressure generated inside a dedicated espresso machine. (Yes, you can also boil the grounds and water together to make “cowboy coffee,” but we’re limiting this discussion to the filter coffee that most people drink.)Ī more complicated extraction process is required to make espresso. The grounds go into the coffee maker, boiling water is allowed to drip through them, and – a few minutes later – black coffee emerges.
Traditional black coffee is pretty simple to make, because the extraction process is simple. So why do they taste so different? It’s because they’re made with different brewing methods. In other words, espresso and drip are just two different types of coffee. The “raw materials” are exactly the same. One thing should be clear at this point: there’s absolutely no difference between coffee and espresso when it comes to the beans, the grounds, or the concept of brewing. Arabica provides a sweeter and smoother taste, but robusta beans are often to brew espresso because they contain less acidity, contain a higher concentration of caffeine, and produce a better crema on top.įinally, coffee and espresso are each produced by running hot water through ground coffee, in order to extract the flavor, aroma and other characteristics we all love. Espresso can also be made from robusta or Arabica beans. Regular drip coffee is usually made from either robusta beans or Arabica beans. (You may see beans or ground coffee sold as “espresso roast” in some stores and online, but that’s simply because the beans have been roasted a bit a bit hotter and longer than dark roast. Dark roast is considered preferable for espresso, but all types of beans can be used as well. All roasts can be used to make drip coffee. The terms “light roast,” “medium roast,” “medium dark roast” and “dark roast” simply refer to how long the beans have been exposed to heat as beans go through the roasting process, they take on different colors and characteristics over time.
Raw coffee beans are roasted at high temperatures to bring out their flavor and aroma. Both regular coffee and espresso are made from the same ground coffee beans, sourced from the same plants and processed by the same roasters. There’s no such thing as an espresso plant, and there are no such things as espresso beans. Green coffee beans are harvested, dried and roasted, and then either sold whole or ground into – you guessed it – ground coffee.
