The Clever Dripper, a full immersion technique, is one of the easiest to use products on the market. Combining the best functions of the french press and pour over techniques, the Clever Dripper is a great tool for the coffee lover who lacks the time to attend to their coffee process. A stop tap at the bottom of the cone allows the coffee to steep before filtering. To  allow the filtering process simply place the brewer on top of your cup, the weight will open the valve and allow the coffee to drain through into the cup. Sip and enjoy.
