CHEMEX coffeemakers are made from the same high quality glass used for lab ware. The Ten Cup Classic series is beautifully clear and imparts no flavors or chemicals into your brewed coffee. Each coffeemaker is inspected, polished and hand tied by one of our team, before getting boxed up for shipping. Used along with the scientifically designed CHEMEX Bonded filters, our pour over system will remove bad fats, bitterness, acidity and sediments that all other types of filters leave behind. Enjoy the perfect cup of coffee, every time you have it.
