Burr Coffee Grinders: Things You Should Know

Pre-ground coffee is readily available, but it loses its taste within a day after being opened. Therefore, a coffee grinder is a must if you want to make the best cup of coffee possible at home.

Grinder types vary, and the best one for you will be determined by your budget, frequency of coffee consumption, and brewing method. We will look at burr coffee grinders in this article.

Burr Coffee Grinders

Stainless steel burrs are used as grinding discs. They grind coffee more consistently than blades. When purchasing, you should search for burrs with sharp edges rather than chunky teeth that smash the beans.

While some grinders advertise themselves as burr grinders, many of them perform more like blade grinders. Despite their name, blade grinders do not have the same level of sharpness as burr grinders. 

There are a few different burr grinders that you may want to consider. Check out these great options If you’re seeking the best burr grinder to brew a delicious cup of coffee.

Automatic

In terms of ease of use and quality, automatic burr grinders top the list. It is possible to get a decent one for about $100, but they can cost up to $1,000 or more. 

Look for an automated coffee grinder that is easy to operate and clean if you plan on purchasing one. Pulse mode is a standard feature on most automated grinders. You should, however, opt for one with auto-grind and timed-grind settings if you expect to grind a lot of coffee.

Manual

The low cost of a manual grinder is perhaps its greatest asset. About $100 will buy you a decent automated grinder. However, you can save money by purchasing a high-quality manual burr grinder. As a bonus, manual grinders are less cumbersome, lighter, and do not contribute to your power cost.

On the downside, grinding requires a lot of effort. For example, to make one cup of coffee, you will need to grind the beans for around a minute. Furthermore, since various brewing techniques need finer or coarser ground coffee, you may have to put in a lot of effort before you can enjoy your morning cup.

Conical Burr Grinder

There are no blades in burr grinders. Instead, the beans are crushed between two burrs, one fixed and the other moving. The conical form of the two burrs of a conical burr grinder allows the beans to be drawn into the mill by gravity. The benefits of this system are numerous: Unlike blade grinders, the mill simply processes each bean once, resulting in uniformly sized particles.

Burr grinders are also significantly more powerful than blade grinders. Conical burr grinders are offered in both electric and manual versions. Because of their small size and low weight, manual burr grinders are perfect for the office or traveling.

A manual grinder is an excellent option if you want to grind your beans the old-fashioned way on a lazy Saturday morning. Electric burr grinders, on the other hand, are more convenient for folks who want to get right into their day.

Flat Wheel Burr Grinder

Flat burr grinders utilize two flat burrs instead of a conical form to smash the beans. The advantages of a flat form include an exceptionally consistent grind, but this also means that ground beans are more likely to become caught and need a more thorough cleaning. Similarly, both manual and electric models are available, with the same advantages and disadvantages as the previous models.

Why Freshly Ground Coffee Beans Are the Best

Those who take their coffee seriously insist that you should grind your beans, ideally just before using them in your coffee maker. Let us start with that.

A large number of volatile compounds can be found in coffee. As a result, when exposed to the outside air, these chemicals become inert. This means that roasted coffee beans should be used within two months. They can also be stored in an airtight container.

However, grinding the coffee beans greatly enhances their surface area and hence their flavor. Ground coffee’s taste components start to degrade almost instantly. A change in flavor can be detected as early as 15 minutes after the coffee beans are processed!

As a result, using freshly ground coffee significantly improves the taste of your brewed beverage. With fresh beans, you will notice a big difference!

Tips for Choosing the Best Burr Grinder

Here are some tips that you will find quite helpful when choosing the best coffee grinder.

Material

Steel or ceramic are the most common materials for burrs, but the titanium-coated burrs on the market now can last a lifetime. The most prevalent burrs are made of steel, which is more efficient at dispersing heat than ceramic burrs if grinding a lot.

Ceramic burrs retain their sharpness for a more extended period than steel ones. However, they are more prone to breakage. The question of which is superior is up for debate. Steel burrs can survive for hundreds of pounds of coffee beans before they need to be replaced, but ceramic burrs can last for decades.

Size

In millimeters, burr sizes vary from roughly 40 millimeters to 80+ millimeters, but the vast majority of home-use grinders fall somewhere in the 60-millimeter region. Larger burrs, on the whole, generate better grinding results and work quicker.

Shape

Various forms, sizes, and materials are used to create burrs. Flat and conical forms are common. Is one form superior to the other in terms of quality? Well, that is a controversial question.

While conical burrs tend to grind quicker, flat burrs create more uniform particle sizes. When grinding for espresso, we recommend flat burrs. When using drip, press, or pour-over brewing techniques, we recommend conical burrs. Several brew processes do not need exact control of the grind size to provide decent results.

Price

It is common for burr coffee grinders to cost more than blade coffee grinders. Burr coffee grinders, on the other hand, come in a wide variety of prices. In addition, there are usually more advanced settings available in higher-end burr coffee grinders.

Features

Look at the burr coffee grinder’s settings after you have decided on the style and price range you are looking for. Many burr coffee grinders feature at least 12 distinct settings which allow you to grind beans into a fine, medium or coarse powder. In addition, special burr coffee grinders may have up to seventy settings, making it easier to create unique coffees.

Grind Consistency

When it comes to brewing great coffee, nothing beats freshly ground beans. For coffee grounds to dissolve at the same rate, they should be the same diameter.

Depending on their size, coffee grounds disintegrate at varying speeds, resulting in some grounds being under- and others over-extracted during the brewing process. The sour and bitter tastes of these under- and over-extracted grinds will be noticeable in your cup of coffee.

Heat

Conical burrs generate much lower temperatures than flat burrs. The lower the RPMs, the less friction between the burrs, and the lower the heat accumulation. The oils in coffee beans can be damaged by sudden temperature fluctuations. This means that until you start brewing, you should avoid heat wherever possible to preserve the exquisite tastes and smells of your cup.

Noise

Flat burr grinders need a higher RPM to guarantee that all the beans are pushed into and out of their grinding chambers. Conical burr grinders, however, operate at a lower RPM and so have smaller motors. Because of this, the conicals are considerably quieter than flat burrs, which are infamous for their high-pitched noise.

Conclusion

If you want to enhance your coffee brewing, you should grind your beans. Freshly ground coffee beans will be a great choice no matter whether you use a coffee machine or make your own. We recommend investing in a high-quality manual burr grinder for the best possible cup of coffee. They are not prohibitively expensive. Invest in an electric burr grinder if you do not have the time to manually grind your coffee in the morning. Happy brewing!
