Use the correct grind for the particular brewing method used.
Type of Grind
Chunky, Kosher Salt
Slightly finer than granulated sugar
Use fresh, cold, filtered water. Hot water from the tap is flat and stale and usually has chlorine in it. If using water from the tap, let it run for a few seconds before filling your coffee pot.
Serve coffee immediately after brewing.
Freshly brewed gourmet coffee allowed to sit on a warmer will begin losing flavor immediately. The longer it is held, the less desirable it becomes. Brewed coffee stays fully flavorful for only 20 minutes.
Never reheat cooled coffee or allow it to sit on a heat source-the coffee will lose its flavor quickly if the brew begins to boil.
