The Chemex coffeemaker, together with Chemex-Bonded Coffee Filter, makes perfect coffee. Clear, pure, flavorful and without bitterness or sediment every time. The coffee only comes in contact with the scientifically designed filter and non-porous glass. With the Chemex method, you can make coffee as strong as you like without bitterness. Perfect for iced coffee and coffee flavoring for gourmet recipes. Because of its purity, Chemex brewed coffee can be covered and stored in the refrigerator for reheating...without losing its flavor!
