One of the things we appreciate the most in this world is a little mad science. Experimenting and having fun with coffee is the cornerstone of why we do what we do, so we’re always game to try out new ways of doing things. When we took on the Hario Cold Water Dripper last year, we had admittedly less-than-stellar results. So while we dug that it was a slow-food approach to making smooth cold brew coffee, it wasn’t high on our list of favorite gear.
Cut to last month when one of our techs, Bryan, decided to experiment with this dripper, then reported to us his findings. What’s the best way for a mad scientist to validate a theory? Perform the proof experiment, successfully, at least one more time! So in came Bunny and the rest is now history.
The cool thing about the Hario Cold Water Dripper is that there is an element of showmanship involved, but it is also relatively hands-off and produces truly delicious coffee. The key is getting the right combination of coffee dosage, water volume, grind particle size and droplet frequency, but equally important is the kind of coffee you’re using and the water you’re brewing with. We find that coffees that come out as a rich, chocolatey espresso tend to taste like actual chocolate milk as a cold brew, while others that have more bright, fruity notes produce an often berry-forward cold coffee. But every coffee you love should be at least experimented with as a cold brew to see how it measures up, so definitely have fun with it!
Watch as Bunny sets up her experiment, then we check back over several hours throughout the day as the Hario Cold Water Dripper slowly produces a delectable batch o’ joe.
