Tetsu Kasuya's Hario V60 Coffee Dripper: Beginner's Guide

What is the Hario V60 Coffee Dripper?

A cone pour-over brewer, the Hario V60 is designed to produce an evenly brewed cup of coffee. Its cone-shaped paper filter adds depth to the coffee layer, making it one of the most popular manual coffee brewers. The water flows to the center, extending its time in contact with the ground coffee.
How is the Kasuya Model Different?

Philocoffea founder and CEO Tetsu Kasuya used to teach using the standard Hario V60 but found that, in many cases, the resulting coffee turned out to be too light. Thus, Tetsu collaborated with Hario to make a variation of the V60 that would be easier for beginners to brew coffee with coarse grind beans.

The standard Hario V60 dripper has ribs inside to help water flow better. The ribs allow air to pass through and for the hot water to flow downwards. More ribs make the water flow faster, which results in a lighter taste. Fewer ribs slow the water flow, resulting in a denser, heavier coffee.

Thus, the Hario V60 Kasuya Model has a special section at the bottom of the dripper about 1cm tall with no inner ribs to slow the flow.

Tetsu spent a year experimenting with different shapes, variations in rib patterns, and placement. Eventually, he chose the one that tasted best with his coarse grind beans, thanks to it providing just the right speed of hot water drainage.

    Ideal Coffees Beans for the Hario V60

    At Philocoffea, we understand that everyone has different preferences when it comes to coffee. If you are just getting started with the Hario V60, we recommend you try Ethiopian beans. In fact, we carry some incredible Ethiopian beans from time to time, so keep an eye on our store’s “Africa” section!

    Ethiopia, the birthplace of coffee, produces some of the best single-origin coffees in the world. The environment is perfect for cultivating exquisite coffee. The beans are either washed or naturally processed. As a result, Ethiopian coffees typically have a higher level of acidity, possess a light to medium body, and offer complex flavor notes with hints of fruity and floral aromas.
