Call it American coffee. Call it filter coffee. By any name, brewed, filtered coffee is by far the most popular preparation method throughout the U.S. and Northern Europe, alive with aroma and rich taste. The method’s origins can be traced to early 20th-century Germany and the advent of paper filters.
Grind is critical. Choose medium, because coffee ground too coarsely will taste weak in the cup. If it’s ground too finely, you can expect a bitter brew. Use a thermal carafe and enjoy within a few hours of preparation, and be sure to clean your machine thoroughly (about once a week for daily users) to eliminate oil and mineral build-up that alter coffee’s taste.
An advice: do not store coffee in a glass pot left on the heating element – it will make your coffee taste burnt, acidic and bitter. Ideally, use a machine with a thermal carafe, or transfer coffee immediately from the glass pot to a thermal container.
