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.
- The Kitchn
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.
- Bean Ground
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.
- Latte Art Guide
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 experts 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.

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 Kitchn
The glass is very thin and fragile, which can make it hard to clean as it will easily break if mishandled.
- Kitchen Lola
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.
- Bean Ground
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.

An Overview On Cold Brew Coffee Makers

Cold coffee has taken off in popularity in recent years, thanks to the inventiveness of various coffee shops. But you don’t have to pay for an iced latte at a drive-thru on your way to work. You can make cold brews in the comfort of your own home.

Your first instinct may be to simply brew regular coffee and pour it over ice. But there are a couple of problems with that. One is that cold brew coffee typically has a stronger coffee-to-water ratio, which means your homemade cold brew may turn out far weaker than you’re used to getting at your favorite coffee shop.

Another issue, as explained by expert Julie Chernoff, is that iced coffee may take too long to brew. Chernoff is a longtime member of Les Dames d’Escoffier, the Association of Food Journalists (AFJ) and the International Association of Culinary Professionals. With a cold-brew coffee maker, you get an appliance dedicated to making a delicious cup of iced coffee.

“The one thing that a cold brew coffee maker can save you is time,” says Chernoff. “Doing it on your own can take half a day or more to really extract the flavor of the coarsely ground coffee beans, whereas a cold brewer does the job in under ten minutes.”

Not all cold brew coffee makers operate at that rate of speed, though. With some models, you’ll find you have to brew for half a day or more. That means you’ll need to make tomorrow morning’s coffee as soon as you get home from work today to ensure it tastes good. But many of today’s cold brew coffee makers come with airtight lids that mean your brew will stay fresh between several days and two weeks. If you choose a brewer with a 2-quart capacity, that means you could make a batch on Sunday and drink on it for several days, depending on your daily consumption.

The Cold Brew Coffee Maker Buying Guide

  • Some consumers simply prefer the taste of cold brew coffee, which is one of the reasons it’s become so popular. It tastes completely different from hot coffee that has been poured over ice.

“Cold brew has a distinctly different flavor profile than traditional hot drip coffee; it leaches out the bitterness that often plagues drip coffee,” says Chernoff. “It’s strong and sweet and far less acidic. The rapid brew versions use an electric pump to manufacture internal vacuum pressure to circulate water through the grounds.”

  • But even within cold brew coffee makers, the taste experience can vary from one to another. One thing affecting taste is the coffee’s freshness, particularly if you won’t be drinking it soon after brewing. Look for a brewer that includes a lid with a tight seal to keep your coffee fresh for days at a time.
  • If you don’t like the first cup of coffee your cold brew coffee maker puts out, don’t give up. You can often tweak the drip settings or adjust the number of beans you use to get just the right concentration of coffee to water.
  • One of the biggest differentiators between cold brew coffee makers is the design. If you have specific preferences, this will immediately push some ahead of others. Some look like Mason jars, while others have a design similar to a beaker. You’ll also find cold brew coffee makers that are designed for you to easily take it with you as you head out the door.
  • Capacity is also an important decider. If you plan to consume less than a few cups of coffee a day, a 32-ounce brewer will likely work just fine. However, if you have more than one coffee drinker in your household, a 2-quart coffee maker may be a better choice. The larger option could also be a good pick if you would like to make coffee for several days at once.
  • As with other drip coffee brewers, you’ll need a filter to hold the coffee while the water passes through it. Some cold brew coffee makers have reusable mesh filters while others rely on paper filters. With the latter, you’ll need to consistently purchase new filters, so that’s an expense to keep in mind.
  • In addition to the difference in reusability, some filters do a better job than others at keeping grounds from ending up in your coffee. Look for one that will give you the purest cup possible.
  • Markings make some coffee makers easier to use than others. Look for a brewer that has markings that make it easy to see liquid levels.
  • Some cold brew coffee makers are dishwasher safe, but with others, you’ll have to wash by hand. Also consider how difficult it will be to clean your filter. You may find it easier to just dump the filter with the grounds, especially since coffee grounds can cause plumbing and septic issues.
  • With many cold brew coffee makers, you’ll need to be a little more patient than with the instant brewers used for hot coffee. In some cases, you’ll need to plan to make it before bed at the latest and let it brew all night.
