How to Choose the Best Burr Coffee Grinder

A grinder is among the most important tools in a home coffee-making arsenal. But which one to buy?

Burr grinders crush beans between two revolving serrated surfaces instead of slicing them using blades. They're generally regarded as superior to blade grinders. But what are the features you should be looking for in a burr commercial grinder?

1. Conical Burrs

The name suggests that a conical burr grinder has one circular burr ring within another ring with the teeth angled. This shape lets it grind more efficiently, as the burrs rotate around a single central point. The angle of the teeth cuts the beans more evenly and generate less heat, which is desirable because excessive heat can cause bitter flavors in your coffee. Conical burrs are also more durable than flat ones. Flat burrs can be susceptible to warping and becoming dull quickly, resulting in unevenly ground coffee. They are more brittle as well, meaning that small stones and other debris can cause damage over time. Flat burrs also produce more noise, and require regular maintenance and cleaning.

Many burr grinders on the market claim to be "burr grinders," but they have flat burrs, or no burrs at all. These "false burr grinders" come with large, flat teeth and are often coupled with weak motors that produce uneven ground. They are not genuine burr mills and contrary to what many enthusiasts think, do not provide the same quality grind as genuine burr mills.

Although some experts disagree with this, others believe that the type of burrs in the grinder can have an impact on the finished taste of the coffee. These theories are mostly anecdotal but have a strong grip on the minds and hearts of coffee lovers. Some believe that conical burrs help bring out the unique flavor of exotic beans, while flat burrs enhance dark roasts.

It could be true. However, it is something to consider in the event that your grinder has significant impact on the quality of your espresso. The only way to know for certain is to try a grinder out with the beans you will be using it with. 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 design or burrs. This is why it's essential to assess a grinder on other criteria such as the reputation of the brand as well as reviews from customers.

2. Convenience

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

According to the company, the grinder uses rotating metal burrs rather than blades to crush beans. This produces more uniformly-sized grounds than a grinder or other burr grinders. The burrs also produce less heat which preserves the flavor and aroma of the beans.

Blade grinders on the other hand they can generate excessive heat and unbalanced-sized ground that affect the taste of your finished cup. Burr grinders are also quieter than blades grinders. However, this may differ by model and brand.

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

The grinders we've tested allow you to control the amount of time it will grind for a specific period of time, which is handy if you're brewing espresso. Certain grinders, such as our top choice Baratza Sette 270, have built-in timers that are precise to only a fraction of a second. But this feature isn't necessary for all brewing methods and the majority of grinders under $200 use what's an improved version of the windup timer.

The most affordable models in our selection, like the Porlex II and the Capresso Infinity--use manual burrs. This means you'll have to crank them by hand to grind your coffee. This is more laborious, but is a great choice if you are seeking an easy compact and affordable alternative that doesn't require electricity.

The Breville Smart Grinder Pro is another option for those who want to save money and uses a burr grinder. It's louder than other models that we have tested, but it's still acceptable if you're not worried about some sound. The more quiet a grinder is likely to be, in general, the more expensive. This is due to the improved materials and advanced soundproofing technology.

3. Easy of Use

A burr grinder is a tool that is recommended by every expert for those who are just getting started with home coffee making. These grinders create a much smaller, more consistent grind than you get from your standard blade grinder and help you produce beverages that are more balanced in body, flavor, and acidity. And they tend to achieve this more effectively. As you'd expect, a high-quality burr mill can cost anywhere from $200 to $200 and is a challenge to use.

So, we spoke to experts and got their recommendations for the easiest-to-use mini electric coffee grinder burr grinders on the market. Many people, even those on a tight budget would recommend the OXO Conical Burr Grinder. It has multiple settings to manage a variety of brewing methods from pour-over, French press, to drip coffee. It performed well during our testing.

It's also quieter than the other grinders with electric motors we've test, and it does not produce more heat than others do. This is important since excessive heat can ruin the delicate scents of your beans.

The OXO grinder has one drawback: it grinds best budget espresso grinder on the coarser end of its range. This can be problematic for espresso. If you like to brew espressos, a burr mill with more advanced features like the Baratza Encore may be a better option.

Manual burr grinders that are powered by cranking, are easy to use and are ideal for those who consume only just a cup or two of coffee per day. These grinders are great for those who travel or just need to make only one cup of pour-over coffee.

Bon Appetit Test Kitchen director Chris Morocco loves the Fellow Ode Gen 2 Burr Grinder with 41 settings that can be easily adjusted and is capable of making an excellent drink for any method you choose--except espresso (the flat burrs made of steel don't grind well enough). It's easy to use for those who don't mind some messes and flyaway particles, and it's also relatively quiet.

4. Cost

A quality burr mill can cost you around a hundred dollars, but it's very worthwhile. 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. They produce a small amount of fines (the tiny bits of ground coffee that are smaller than the official grind size you choose), but this won't be noticeable to most average drinkers, and it's a small price to pay for excellent-tasting consistent coffee grounds.

Flat burrs are two discs with cutting teeth facing one another. They are less common but are preferred by coffee enthusiasts because they produce a more consistent size of grind, ideal for French press and espresso. The downside is that they can be expensive to purchase, and you may require a new burr for each roast level or brew type.

The Baratza ESP has the most cost-effective combination of price and capabilities for a burr mill, according to our experts. It's less than $200, which is a lot less than the majority of other models that don't offer the same level of capabilities. It comes with an incredibly flat 64-mm burr set which is perfect for any brewing method and is easy to upgrade with other sets, like those from SSP.

The OXO is another affordable option with a solid performance record in our tests. The burrs in this model aren't as precise, as ones in more expensive models, but its user interface and multiple settings are suitable for both French press and drip. The OXO is a great entry-level model for a lot of people. True coffee geeks may want a more sophisticated model however the OXO is suitable for those who are.

For those who prefer to grind their beans manually We also tested a handful of manual burr grinders, which are great for those on the move and who are able to make one or two cups at a time. These models, which employ the same mechanism for grinding as electric burr grinders operate with an actual crank, not motors, and are generally much quieter than electric units.
