Cold Bruer Brewing Guide
Measuring the coffee.
Measure out 2/3 cup (60 grams) of ground coffee.
We recommend using:
• A medium grind level (eg. pour over grind)
• Fresh roasted coffee
• Medium roast
Assembling the Filter.
When assembling the filter make sure
the finer side of the mesh is facing up.
Pop the glass tower into the filter.
Add the coffee to the Tower.
Pour the measured ground coffee into
the tower, brush any loose grounds
down into the chamber.
Shake the Tower to level out the
Drop in a paper Filter.
Carefully place the Tower into the Carafe.
Drop a Paper Filter on top of the coffee bed.
Pre-wet the coffee.
Pre-wet the coffee with about two fl.
ounces of water to evenly soak the
Insert the Valve.
Carefully push the plug down into the
tower. Wet the lip of the seal to help it
slide in easily.
Measure out the water.
Measure out 24 fl. ounces of an ice
and water mixture (about half water
and half ice).
Pour the mixture into the tower.
Setting the drip rate.
When the Laser Etched Line on the Stainless Steel Valve Tube lines up with the slot in the silicone, the Valve will be fully open.
Turn the Knob clockwise to slow down the drip rate.
We recommend setting the drip rate to one drip per second which will fall somewhere in the "target range."
Enjoying Cold Brew
Cold Bruer makes ready to drink cold brew.
Your brew might be a little stronger than a normal cup of coffee. Try pouring it over ice, or adding a little cream to dilute it to a normal level.

Storing cold brew.
Cold brew will last up to two weeks in the fridge.
Cold Bruer’s dual functioning lid can be plunged
into the Carafe to make an air tight seal.
Cold Bruer Cleaning
Removing the coffee grounds.
First pop out the valve from the tower.
Then, over the trash, peel off the Filter
from the bottom.
Give the Tower a swift shake, and the
coffee will slide right out!
Washing the glass.
All parts of Cold Bruer are dishwasher safe.
Although we have found it easy enough to
just rinse them off in the sink.
Washing the Filter.
The filter can be a little tricky to clean.
Peel the metal filter from the silicone to
rinse away all the grounds.
We recommend a product called Cafiza to remove
the coffee oils from the filter and glass.

Is the Cold Bruer Dishwasher Safe?
Yes. All parts of the Cold Bruer are dishwasher safe.
How long does Cold Brew coffee stay fresh?
Cold Brew coffee stays fresh for up to two weeks if properly stored in an airtight container and left in the refrigerator.
Does Cold Bruer produce a Concentrate?
No. The slow-drip method does not produce a concentrate like other methods of cold brewing. Although you can use less water in the Tower if needing to make a concentrate with the Cold Bruer. Check out our blog
Making Hot Coffee with Cold Brew
to find out the proper ratios.
Can I heat up Cold Brew?
Absolutely. Here’s how we do it
Making Hot Coffee with Cold Brew.
Can I use a non-disposable filter instead of a paper filter?
No. The paper filter (which is an Aeropress Filter) is used to disperse the water evenly over the coffee grounds. It does not do any of the filtering itself. A non-disposable filter will not work because it will not disperse the water evenly like a paper filter will.
Can I brew with tea?
Yes, absolutely you can brew with tea. Here’s our blog post on the subject -
Experiments with Tea.
Is Ice Necessary?
Yes. We highly recommend using an ice/water mixture. Keeping the water at a cool, constant temperature prevents air bubbles from forming in the water. These air bubbles are produced when the water temperature changes and they can sometimes slow or stop the valve. You can also brew in the refrigerator to help reduce the air bubbles, but we find ice works the best. It should be noted that the idea is to have ice in the tower throughout the brew cycle. Adding room temperature water on a hot summer day will most likely melt the ice quickly. We’d suggest making your best estimate for ice throughout the cycle.
I set up my Cold Bruer and the drip stopped?
This is most likely caused from the above question. Brewing with ice will prevent air bubbles from forming that slow or stop the Valve. However, another area to focus on is making sure the CO2 Valve (inner tube) is clear from all obstructions. This sometimes occurs when washing the Cold Bruer and little water droplets get in the chamber preventing the gases from escaping. To avoid this problem, always check the valve and give a light blow through the chamber to clear it from any water.
I finished my brew cycle and there are dry coffee grounds.
This is almost always due to coffee that is well past its roast date. We strongly recommend using freshly roasted coffee - preferably within one month of its roast date. If you need any recommendations on finding good coffee in your neighborhood, please send us a message and we’ll try to connect you with the closest roaster near you.
I accidentally pulled the CO2 valve out, now what?
No problem. Just make sure you insert it back through the center hole. Don’t push it through too far though. You want it to align perfectly with the bottom Silicone. If you’re still having trouble inserting the Valve, message us at firstname.lastname@example.org and we’ll send some troubleshooting pictures to help you along.
Do you offer International Shipping?
Yes! We use USPS for all international packages. The shipping rate is $35 for international orders, and $25 for Canada.
