The Clever Dripper gives you full flavor extraction and good body. The stopper at the bottom allows water to drain when the filtercone is placed on a cup. It’s made of durable BPA-free plastic and is easy to disassemble for cleaning. The Clever Coffee Dripper combines the best features of French press and filter drip brewing. It combines control over steeping time with a sediment-free cup. Like all filtercone brewing methods, you directly control the water temperature, water to coffee ratio, and the infusion time.
