The main difference between espresso and drip coffee is the way coffee is made in a traditional espresso machine versus a drip coffeemaker. Espresso is made with very little water added to the coffee, and is mostly traditionally made with the use of a French press. The water is boiled and poured over freshly ground coffee. This creates a very concentrated coffee solution, much more so than other methods. This concentration gives the brewed coffee its darker colour. The original espresso method of making coffee also uses very little water, and the resulting coffee is typically rather sweet.
Coffee Roasting Beans For drip coffeemakers, the coffee is not roasted and therefore does not contain any caffeine. When coffee is roasted, all the properties that are responsible for giving coffee its flavour are destroyed. The roasting also causes a lot of chemical reactions to occur, which affects the flavour and aroma of coffee as well. However, when dark roasted coffee beans are pushed to the extreme of being roasted completely, they do not lose their flavour or aroma.
When you purchase coffee, you will find that there are two different types: Light roasted (or regular) and Dark roasted (or specialty). You can also buy pre-roasted coffee beans, if you prefer not to roast your own beans. Coffee beans should be purchased based on how light or dark they are, as this will determine how much caffeine they contain per serving. Coffee Roasting can be very expensive if you are purchasing beans based on the type of roast. Some people prefer a more mild roast, and so purchase a lower quantity of beans; however, if you want a stronger cup of coffee, then opt for a higher quantity of medium roasted coffee beans. Coffee beans are sold in three grades, as follows: elite, standard, and specialty.
