The V60 dripper, also called cup dripper or dripper mug is probably the best coffee dripper out there. The king of glass Hario has been manufacturing glassware since early 20th century and V60 set-up is one of their most popular brewing inventions. The bigger V60 02 size is preferred by cafes and baristas to brew 1 to 6 cups (depending on your cup size). The Hario V60 drippers retain the heat much better than a regular fan dripper. The Hario coffee dripper produces more extraction than the flannel filter .
