How to Choose the Best Burr Coffee Grinder

A coffee grinder is a vital tool for any home coffee maker's arsenal. Which one should you buy?

Burr grinders crush beans between two revolving serrated surfaces instead of cutting them using blades. They're considered to be superior to blade grinders. But what features should you look for in a burr grinder?

1. Conical Burrs

A conical burr mill has an angled set of teeth and the ring of a circular burr that is placed between the other. This design allows for more efficient grinding process, since the burrs revolve around an axis. The angled teeth are more efficient in cutting beans evenly and produce less heat. This is good because excessive heat can create bitter taste in your coffee. Conical burrs also last longer than flat burrs. Flat burrs tend to warp and dull quickly, which results in unevenly ground espresso. They are more brittle as well, meaning that small stones and other particles could cause damage over time. Flat burrs also produce more noise, and require regular maintenance and cleaning.

A lot of burr grinders sold on the market are marketed as "burr grinders," yet they have flat or no burrs. These "false burr grinders" have large flat teeth and are often coupled with motors that have weak components that produce irregular ground. They aren't true burr mills and contrary to what many enthusiasts think, do not produce the same quality grind as actual burr mills.

While some experts do not agree with this, others believe that the type of burrs used in the grinder have an impact on the finished taste of the coffee. These theories are largely anecdotal but they hold a firm grip on the minds of coffee enthusiasts. For example, some think that conical burrs can bring out the individual flavors of exotic beans, while flat burrs are able to soften and enhance dark roasts.

This could be the case. However, it's something to consider when you are deciding whether your grinder will have significant impact on the quality of your espresso. Only by testing the grinder with the beans that you intend to use can you be certain. The overall design of the grinder as well as its features of operation will have more of an influence on the final cup than the type or burrs. This is why it's important to assess a grinder on other factors like the reputation of the brand as well as reviews from customers.

2. Convenience

The Baratza Encore is a burr grinder that a lot of coffee lovers swear by. Many reviewers have praised it as an "time-tested option" that provides excellent value for money and is well suited for drip, pour-over, French press, and cold coffee.

The grinder uses burrs that rotate instead of blades to grind the beans, which produces larger, more uniformly-sized grounds than a blender or another burr grinder, according to the company. Additionally the burrs create less heat while they grind and preserves more of the bean grinder coffee machine's flavor and aroma.

Blade grinders, on the other hand, produce excessive heat and unevenly-sized grounds, which affects the flavor of the final cup. Burr grinders are also quieter than blades grinders. However, this can differ by model and brand.

Although the majority of burr grinders we tested have conical burrs, some make use of flat burrs (two discs with cutting teeth facing one another). These grinders are not recommended for espresso because they are difficult to calibrate. They are also cheaper and less difficult than top-end flat-burr grinders such as the Fellow Ode Gen 2 and the Baratza Virtuoso+.

The grinders we tested let you select the amount of time the machine will grind, which is useful when you're making espresso. Some, like our top choice, the Baratza Sette 270--have an inbuilt smart timer that can deliver split-second precision. However, this feature isn't essential for all brewing methods and the majority of grinders under $200 are based on a fancier version of a windup timer.

The cheapest models, like the Porlex II or the Capresso infinity, use manual burrs. This means you need to turn them by hand yourself to grind your coffee. This requires more effort however, it's a good choice if you want simple, compact and inexpensive option that doesn't require electrical power.

The Breville smart commercial grinder pro (click to find out more) is another option for those who want to save money and uses a burr grinder. It's louder than some of the other models we've tried, but still tolerable for those who don't mind a little noise. In general, the more expensive the coffeee grinder is the quieter it's likely to be due in part to the improved materials and advanced soundproofing technologies.

3. User-Friendliness

If you're just beginning to discover the world of home coffee brewing there's one piece of equipment that everyone agrees is necessary: a burr grinder. They produce an even, finer grind than a blade grinder, and can help you create brews with better balance of the flavor, body and acidity. They are typically more reliable. But, as you expect, top burr grinders can cost upward of $200, and some are difficult to operate.

So, we talked to experts and obtained their suggestions for the most user-friendly electric burr grinders that are available on the market. They recommend the OXO conical burr grinder for many people as well as those who don't want to spend a lot of money. It has multiple settings that allow it to accommodate a variety of brewing methods from pour-over, French press, to drip coffee grinders sale. And it performed well during our testing.

It's also quieter than other grinders with electric motors we've tested, and it doesn't produce more heat than other grinders do. That's important, as excess heat can damage the delicate aromas in your beans.

The OXO grinder's biggest drawback is that it's best in grinding at the coarse end of its range which could be a problem with espresso. If you're a fan of brewing espressos, a burr grinder with more advanced features, like the Baratza Encore may be a better option.

Manual burr grinders that run by cranking are simpler to use and perfect for those who consume only a cup or so of coffee per day. These grinders are perfect for those who travel or who only require only one cup of pour-over coffee.

Chris Morocco, Bon Appetit Director of Test Kitchen, is a fan of the Fellow Ode Gen 2 Burr Grinder. It comes with 41 settings that are easily adjustable and will make a fantastic beverage using any method - except for espresso (the burrs made of flat steel don't grind precisely enough). It's easy to use for anyone who isn't afraid of a little messes and flyaway chaff, and it's quiet.

4. Cost

A quality burr grinder will cost you about a hundred dollars but it's worth the price. The grinding mechanism is simple enough that even a beginner can figure out how to get the most out of it, and you'll save money in the long run by ditching the pre-ground coffee and bad-for-the-environment coffee pods.

Conical burr grinders are the standard in electric home units, and they're a great choice for most people just starting out with this whole grinding-your-own-beans-at-home thing. The grinders create a tiny amount of fines, which are the tiny pieces of coffee ground that are smaller than the size of the official grind you choose. However, this is not evident to the majority of coffee drinkers.

Flat burrs are two discs that have cutting teeth that are facing each other. They are not as common but are favored by coffee enthusiasts because they produce a more uniform grind size, which is ideal for French press and espresso. The downside is that they are expensive to purchase, and you might require a new burr for each different roast level or brew type.

According to our experts, the Baratza has the best conical burr grinder price and capabilities for a burr mill. It's less than $200, which is much less than other models that don't have the same capabilities. It comes with a 64-mm flat burr set which is perfect for any brewing method and is easy to upgrade to other sets similar to the ones from SSP.

The OXO is a similar model that is affordable with a good performance record in our tests. The burrs in this model aren't as precise as ones found in higher-end models however, its user interface and a variety of settings are suitable for French drip and press. While true coffee lovers will want a more advanced model but the OXO is a great entry point for most people.

For those who prefer to grind their beans by hand, we also tested a few manual burr grinders, which are great for those on the move and who only need to make one or two cups at a time. These models, which employ the same mechanism for grinding as electric burr grinders, operate with the use of a crank rather than motors, and are generally much quieter than electric units.
