The Hario V60 01 is a cone-shaped pour-over brewer designed to produce a well-balanced coffee brew. This balance is created by the unique design. There are ridges along the sidewall of the V60 dripper which allow water to extract out of the side of the V60 as well as the bottom. This design helps provide a nice even extraction. The V60 01 is the small size of the Hario V60, ideal for brewing coffee for one or two people.
