Many factors effect brewing the perfect cup of coffee. Your coffee maker pot and filter container need to be thoroughly cleaned at least once a week.
Bitter oils stick to the glass container and plastic filter holder.
Protect coffee from moisture, light and air to preserve the flavor. Keep coffee in an air tight container and store in a cool, dark place between 50 and 70 degrees Fahrenheit. Freezing fresh coffee will prolong its life. On the other hand, daily removal of the container from the freezer can cause moisture to freeze on the coffee and effect the flavor. For the perfect cup, use nothing but the best quality Arabica beans.
