Expert Reviews


What reviewers liked

The Bruer opened my eyes to slow-drip cold brewing. I had trouble with the "Gosh! Dripo" slow-drip cold brewer, but the Bruer turned me around. It makes a delightful, concentrated, virtually grit free cold brew.

The Cold Bruer by Bruer is easily the most beautiful and unusual cold brewer we tested. It's mesmerizing to watch brew, and is the only cold brewer that yields coffee that's ready to drink instead of a concentrate that should be mixed with water, milk, or ice.
This scientific-looking contraption won because of its speed. The water drips down into the grounds and drips out into the bottom carafe. It still takes around four hours, though, but that’s better than having to wait overnight. It doesn’t make concentrate, either — just ready-to-drink cold coffee.
One of the biggest benefits of using the Bruer is that it will produce great tasting coffee that will leave you wanting more. The coffee has low acidity which is excellent for a sensitive stomach.
However, once you’ve taken the time to truly master the Bruer cold brew drip coffee maker, it does churn out some great tasting cold brew coffee.
-
The key feature of the Bruer is that you can adjust its drip speed. This means you can experiment with different drip settings to vary the taste of your coffee. Combine this adjustability with its heat resistant glass, stainless steel core, and silicon interiors – it makes for an elegant drip solution perfect for home use.
Sturdy in materials and build. Compact design. Clever and effective system of lids. Takes standard-size filter papers.
Transparent and entertaining hence you can watch the brew cycle from the time it starts to when it finishes.

What reviewers didn't like

It's not foolproof. You must follow the directions precisely, including using ice—and if your coffee grind is too fine, water may form pathways through it, like an ant colony. If what's dripping out doesn't look dark, or it's coming out quickly, adjust your tactics. It also only holds 20 ounces of water, and since it's made of glass, it's fragile. Some buyers have complained of drip valve issues, but I have not encountered any yet.
- Wired
It requires a lot of set up and it can be difficult to set the valve so the right amount of water trickles into the coffee grounds. The glass exterior is also easier to break. It’s also an expensive system, coming in second to the KitchenAid.
It technically makes less than the other gadgets on this list.
The glass is very thin and fragile, which can make it hard to clean as it will easily break if mishandled.
The downside of the Bruer is the price at nearly 3-times to cost of the above Iwaki, it’s not cheap. For anyone just getting their feet wet and venturing into cold drip coffee, the high price tag may not be worth the initial investment and you’d be better off with the Iwaki which works in the same way albeit without the option the regulate the drip rate.
-
Valve that modulates the drip rate is difficult to adjust. Drip rate may be difficult to observe owing to poor visibility in the ground coffee chamber.
The glass it thin thus making it very fragile. It is very hands on compared to other coffee makers due to its steeped learning curve.
