It was 1908 when a German housewife, Melitta Bentz, made coffee history. Tired of the bitterness and troublesome grounds in her daily brew, Melitta poked holes in the bottom of a brass cup and lined it with a sheet of her son's blotting paper. She then filled the cup with ground coffee and poured in hot water, thereby creating the pour-over filtration system. The results - rich flavorful coffee without bitterness or mess. This innovation changed the way people worldwide make their coffee, becoming the precursor to modern day drip coffee brewing. Over 100 years later, Melitta remains dedicated to the pursuit of the perfect cup of coffee. melitta.com. Facebook: Facebook.com/MetlittaUSA.
