Every drop creates the finest coffee. The slow drip thoroughly extracts the flavor of the coffee. It is designed to compliment modern interior design. The coffee strength can be changed by adjusting the faucet. Usage: Water and ice (or just water) go in the top chamber, coffee in the middle (pre-saturated with water) and, with the aid of a metal valve on the base of the top chamber, you just start dripping. We suggest one drip every 1-1.5 seconds, which gives a brew time of 5-7 hours.
