The Hario V60 is an incredible tool for brewing precision. The wide, single opening on the bottom of the V60 makes for lots of room for variability when brewing, change how heavily you pour the water from you kettle, change grind size, change temperature of water... all of these things are likely to make noticeable changes to the flavor of coffee you end up with. Yum! Fun!
"The HARIO V60 is the "dripper that can create variations of flavor for those who brew coffee". You can change the flavor tailored to various preferences by adjusting the brewing method, while ensuring a proper extraction of delicious taste and aroma from the coffee beans."
