They call these the "Classic" model and we offer them in the 6 cup size (30 oz) and 10 cup size (50 oz.) The brewer includes the one-piece machine-made glass coffeemaker, and wood collar handle with leather tie. There are a few key advantages to using a Chemex compared to an auto-drip brewer. The first point is that the coffee-water mixture is the right temperature (between 195-205°F) from the beginning of the infusion. Few auto-drip makers are capable of this and even a good auto-drip maker will brew at lower temperatures. Secondly, you gain control over infusion time based upon the fineness of your grind and pouring technique.
