Hario V60 Drip-Assist Set - Size 02

The original idea behind the V60 Drip-Assist (why you wanted to make “Drip Assist”?)
Drip-Assist is a product that I have imagined for a long time. With auto brewers, it is very common to have a spray head which helps distribute the water consistently into the grounds. So Drip-Assist is my way of creating a highly usable water pouring pattern that creates a high-quality cup of coffee as well as a very consistent product.

What aspect of Drip-Assist are you most insistent on?
Two sized holes. It is important to be able to pour water quickly when needed, which the inner holes achieve. At the same time, a fairly slow and dispersed shower of water is needed for a more gentle water movement through much of the brew. By having both sizes, you are able to manipulate enough of the brew to create fantastic results.

A Message that you would like to share with consumers. (about the V60 Drip Assist)
Use the centre, high-speed holes for your bloom. Then use the exterior holes for your brewing. You can either pulse brew or continuously pour the water. It is also a good idea to pour a little water into the centre holes from time to time to ensure the coffee bed is interacting evenly. If you pour continuously, allow excess water to flow into the centre chamber to automatically add that little extra turbulence.

Any other comments / thoughts about Drip Assist
Experiment with pours through the various-sized holes. If you find too much variance in the coffee bed, try pulsing less often. Or if the centre gets too mounded after brewing, try pouring more water in the centre holes next time. The standard Drip Assist brew results in a bowl-shaped coffee bed when used with the paper filter only. When used with the flat filter, it should be mostly level. Keep in mind that the larger your dose, the more you will need to pulse the water. With more doses, the brewing chamber fills up more quickly and needs a few seconds to drain a bit more.
