Nothing comes between your ground coffee beans. This is exactly the reason why coffee tasters use this method to determine the quality of coffee beans. No paper filter not only means no waste, but that the coffee bean’s essential oils go directly to your cup, delivering the flavor that is lost on paper filters. Simplicity works best and is the reason why the Chambord’s design has not changed a bit from its original drawing. Make taste, not waste! 0.6L, 17 oz capacity.
