I really like the Clever Dripper and believe it greatly improves the quality of brewed coffee. And it is so simple! You get full flavor extraction every time and good body. The silicone stopper at the bottom sets this brewer apart from normal drippers: water only drains when the filtercone is placed on a cup. It's made of durable plastic, and is easy to disassemble for cleaning.
In essence, the Clever Coffee Dripper combines the best features of French press and filter drip brewing, eliminating the drawbacks of each. With French press brewing, you have control over steeping time, but heat loss and sediment in the cup can be a problem. Brewing with a paper filter is easy and convenient; the problem is lack of control over steeping time (i.e. the coffee begins to drain immediately). By adding a stopper to the filtercone, the Clever Coffee Dripper combines control over steeping time with a sediment-free cup. We call this a "full immersion brewing" method. Like all filtercone brewing methods, you directly control the temperature of the water, ratio of water to coffee and the infusion time.
A box of #4 Filtropa filters is included. The dripper will fit on cups and thermoses with tops wider than 1.5" and less than 3.75" in diameter. Of course, if you put the dripper on a very narrow thermos, you should make sure the dripper is stable. BPA-free plastic. Not dishwasher or microwave safe. 18 fluid oz. max capacity.
The slicone gasket and stopper are extremely durable but if for some reason you need to replace these parts on your Clever, please email us at firstname.lastname@example.org and we will send you a set.
