Hario Water Dripper Tower

By slowly dripping cold water through the coffee grounds over several hours, the process minimizes the extraction of acidic compounds and bitter oils. The result is a much smoother, cleaner, and naturally sweeter concentrate compared to immersion-style cold brew.

It takes a little practice to get the hang of it. You adjust the valve to achieve a steady drip rate—typically one drop per second—and you may need to check it occasionally during the first hour to ensure the flow remains consistent as the water level drops.

The tower has a capacity of 26 ounces. Because the output is a highly concentrated coffee extract, this amount will yield several servings once diluted with water, milk, or ice.

The glass is high-quality, but like any premium glassware, it requires careful handling. Cleaning is straightforward, though you will need a bottle brush to reach the bottom of the carafe and the coffee chamber effectively.

Yes, once you have set the drip rate, it is designed to run on its own. However, because the brew time is approximately five hours, it is best to set it up in a location where it won't be bumped or disturbed.
