Chemex coffeemakers are made from high quality borosilicate glass, which is beautifully clear and imparts no chemicals or flavors into the coffee. Chemex Bonded™ filters are scientifically designed to remove bitterness, acidity and sediments. This flawless blending of art and science ensures you will get the full flavor of the coffee beans-and nothing else. Larger than a V60, it's more ideal for a bigger yield- to share or not is up to you. A good brew ratio on these 6 cup brewers will yield two cups of coffee.
