Bruer Cold Drip Coffee System

What is the Bruer Cold Drip System?


The Bruer cold drip coffee system utilizes a slow drip cold brew method for making coffee. The Bruer was created in 2013 by the mechanical engineer, Gabe Herz, and industrial designer, Andy Clark. It was designed to retain the aesthetic value of a cold drip system, but to be far more practical and affordable than traditional glass setups.

The duo met during a project in the Santa Cruz Mountains and discovered their mutual love for coffee, brewing and design. From this passion the Bruer was born, with Herz and Clark founding their company in September 2013, along with their mission: “Celebrating the ritual of coffee through design.”

Using their collective skills in engineering and design, as well as manufacturing connections in China, Herz and Clark designed their Bruer prototype and began a Kickstarter campaign to make their dream a reality.

According to their Kickstarter campaign, the Bruer Cold Drip Coffee System was designed with the visual appeal of cold brewing and the intimacy of ritual in mind. The clear borosilicate glass chambers allow the brewer to observe every stage of the process and is a three level system: water level, ground coffee level, and coffee collection level.

“Water slowly drips from the water chamber into the coffee chamber, saturating the coffee. Once the coffee grounds are saturated the coffee drips down into the coffee pot. This is a slow process; it can take anywhere between 3 and 12 hours depending on drip rate”. Herz and Gabe explain, “Our design goal was to highlight this vertical visual while offering a simple process, clean aesthetics, and extraordinary function.”

The drip rate can be adjusted using the 304 stainless steel adjustment knob, keeping in mind that each adjustment you make will be quite minor to make any change to the drip rate. The filter used in the Bruer cold drip coffee system is a regular AeroPress filter to evenly distribute the water, which sits on top of the coffee in the tower. 

This product is all about the combination of simple production and artistic flair while remaining affordable and without compromising on flavour.

How to Use the Bruer Cold Drip Coffee System

What you will need:

Brew Time:

3-12 hours (depending on drip rate)

Bruer Cold Drip Brew Ratio:

60g coffee, ground for paper filter, to 600ml of ice and/or cold filter water. 

Step 1: Grind your coffee at a setting just above medium or cold drip setting (coarser than paper filter).

Step 2: Pour your ground coffee into the brewing chamber (bottom of the top chamber) and level it out.

Step 3: Carefully place the round Aeropress paper filter on top of the coffee. The filter makes sure there is even water dispersion.

Step 4: Ensure the valve is completely closed - line up the laser etched mark on the steel with the slot in the silicon (this is fully open), then turn the rod clockwise to the last marker before the slot to close the valve. Put the silicon plug/valve in the Bruer and make sure it is sealed.

Step 5: Pour the ice and /or water in the top chamber.

Step 6: Turn the valve back the other way until you get the desired drip rate. For a 3-4 hour brew time, you should set the Bruer to 1 drip per second. You can set it slower for a longer brew time.

Step 7: Place lid on top of the chamber and allow to drip until all the water has settled in the decanter.

Step 8: Lift the top chamber out and place lid on the bottom chamber with your brewed cold drip in it. Place this in the fridge for a few hours to chill then enjoy your brew straight over ice, or, with a little milk or water.

Step 9: To clean, remove seal and filter from the brewing chamber. Remove grind (filter is biodegradable, so grinds and filter can go directly into the compost or bin) and rinse the Bruer and filter in hot soapy water and air dry.
