Coffee Grinding – How Grind Size Affects Coffee Flavor

Coffee remains a popular beverage across the US and beyond. With more than 400 million coffee mugs consumed daily in the US, one appreciates the sprouting of coffee shops donning American civility. Some people use coffee as a pick-me-up in the morning while others simply indulge in its exquisite flavors.

Coffee flavors

Depending on the coffee brewing and grinding process, one can enjoy a variety of coffee flavors. The coffee bean itself has over 800 volatile and non-volatile compounds that contribute to its unique flavors. And depending on the roasting process, coffee beans can take on different characteristics. For instance, lightly roasted coffee beans have a higher acidity level while dark-roasted coffee beans are smokier with less acidity.

Coffee grinding

The coffee grinding process is key to unlocking the coffee bean’s flavor potential. Grinding coffee beans helps to release the coffee’s essential oils and aromatics, which results in better-tasting coffee. But with so many different types of coffee grinders on the market, it can be difficult to know which one is best for you.

2 Best Coffee Grinders

  • Blade coffee grinders

    Blade coffee grinders are the most common type of coffee grinder. They work by chopping coffee beans into smaller pieces. Blade coffee grinders are typically less expensive than burr coffee grinders, but they can be less consistent and produce more coffee dust.

  • Burr coffee grinders

    Burr Coffee Grinders use two revolving abrasive surfaces (burrs) to crush and grind coffee beans. The distance between the burrs can be adjusted to produce coffee grinds of different sizes. Burr coffee grinders typically cost more than blade coffee grinders, but they are more consistent and produce less coffee dust.

Burr Coffee Grinders

The type of coffee grinder you choose will largely depend on your budget and desired level of consistency. But regardless of which coffee grinder you choose, the quality of your coffee grinds will have a big impact on the flavor of your coffee.

If you’re looking to make the best coffee possible, we recommend using a burr coffee grinder. But if you’re on a budget, a blade coffee grinder will also get the job done.

Why Does Coffee Grind Size Matter?

Coffee grinding is one of the most important steps in brewing coffee. It can be the difference between a mediocre cup of coffee and a great one. But what is coffee grinding, and how do you do it?

Importance of coffee grinding

The finer you grind your coffee beans, the more you increase the exposed surface area of the grounds, resulting in faster extraction. That’s why coffee for espresso machines is ground fine, since the water from an espresso maker passes very quickly at high pressure through the grounds.

Once you’ve ground your coffee, it’s important to brew it immediately. Coffee begins to lose its flavor soon after grinding, so you want to make sure you brew it while the coffee is still fresh.

No matter what method you use to grind your coffee, the important thing is to experiment and find what works best for you. There is no perfect way to grind coffee beans, so find what works best for your taste and your coffee brewing method.

Types of coffee grinds – Types of Ground Coffee

what are the Types of coffee grinds

There are three main types of ground coffee grinds: coarse, medium, and fine. Each type of coffee grind is best suited for a different brewing method.

  • Coarse Coffee Grinds: Coarse coffee grinds are best for French press coffee and coffee makers with built-in filters. The large coffee particles extract slowly, so they don’t over-extract and make the coffee taste bitter.

Coarse coffee grinds

  • Medium Coffee Grinds: Medium coffee grinds are best for drip coffee makers and pour-over coffee makers. The medium-sized coffee particles extract quickly and evenly, providing a well-balanced cup of coffee.

Medium coffee grinds

  • Fine Coffee Grinds: Fine coffee grinds are best for espresso coffee. The small coffee particles extract quickly and produce a strong, concentrated coffee.

What is The Best Way To Grind Coffee Beans? 

The best way to grind coffee beans is to start with whole, freshly roasted beans and use a quality burr grinder. A burr grinder is an essential tool for achieving the perfect grind size for brewing unique and flavorful cups of coffee. Burr grinders create two abrasive surfaces which crush the beans’ cells evenly and consistently, resulting in an even grind.

When choosing a burr grinder, look for one with adjustable settings that allows you to adjust the size of the grind. This will let you achieve a range of grind sizes appropriate for different brewing methods: from a coarse grind for French press coffee to a finer grind for espresso or Turkish coffee.

Once you have the right burr grinder and grind size, begin by pouring whole beans into the hopper. Make sure not to overfill it; aim for no more than two-thirds full. Then turn on the grinder and adjust its setting according to your desired grind size. Keep a close eye on the process to make sure that you are getting the right grind size.

Once your beans are ground, transfer them to an airtight container or grinder. This will prevent oxidation and keep the flavor of your coffee fresh for longer. Go ahead and follow our procedure to grind coffee beans and tell us how it goes. 

How to grind coffee beans

There are two ways to grind coffee beans: with a coffee grinder or without a coffee grinder.

If you don’t have a coffee grinder, you can grind coffee beans by hand. The best way to do this is to use a mortar and pestle. Place the coffee beans in the mortar and use the pestle to grind them into a coarse powder.

If you have a coffee grinder, you can use it to grind coffee beans. Most coffee grinders have two settings: one for coarse grinds and one for fine grinds. Experiment with both settings to see what works best for your taste and the coffee brewing method.

How to grind coffee beans

When grinding coffee beans, it’s important not to over-grind them. If the coffee beans are too finely ground, they can clog the filter and make the coffee taste bitter. If the coffee beans are too coarsely ground, they won’t extract fully and the coffee will be weak.

The best coffee grinds for French press coffee are coarse or medium. For drip coffee, the best grind is medium. And for espresso, the best grind is fine.

Do Different Coffee Beans Grind Differently? 

Yes, different coffee beans grind differently due to their unique characteristics. For instance, denser beans generally tend to be harder to grind than lighter ones and hence require a finer setting on the burr grinder. For optimal results, adjust the grinder’s settings to the type of coffee bean used.  Experimenting with different grind sizes and coffee beans will help you perfect your coffee grinding technique.

How to decide the type of grind one wants

The type of coffee grind you use will largely depend on your budget and desired level of consistency. But regardless of which coffee grinder you choose, the quality of your coffee grinds will have a big impact on the flavor of your coffee.

Coffee tip 1

The finer the coffee grind, the bolder the flavor. So if you like your coffee with a strong flavor, you’ll want to use a finer grind. A typical American coffee mug carries a medium grind whilst an espresso machine uses finely ground coffee.

Factors affecting coffee grind

Factors affecting coffee grind

There are a few key factors that affect coffee grind, including:

  1. The type and age of coffee beans you’re using. Different types of coffee beans grind differently. For example, lightly roasted coffee beans grind more easily than dark roasted coffee beans. Aged coffee beans require a finer grind.
  2. The coffee brewing method you’re using. Different brewing methods require different grinds. For example, French press coffee requires a coarse grind while espresso coffee requires a fine grind.
  3. The coffee grinder you’re using. Different coffee grinders produce different results. Some coffee grinders are better at grinding coffee beans evenly while others produce more consistent results.

How to store ground coffee 

Once the coffee is ground, it starts to lose its flavor. So it’s important to store coffee grinds in an airtight container in a cool, dark place. Coffee grinds can be stored for up to two weeks.

Frequently Asked Questions on Coffee Grinding

Can I grind coffee beans without a grinder? 

Yes. Use a food processor or blender to achieve a coarse grind. Alternatively, you can place the beans in a plastic bag and crush them with a rolling pin or other heavy object. However, these methods are not as accurate and efficient as using an electric burr grinder. For the best results, we recommend investing in a quality burr grinder. 

Is it worth grinding your own coffee?

Absolutely! Grinding your own coffee beans ensures that you get the freshest and most flavorful cup of coffee possible. The right grind size is essential for achieving the optimal extraction rate, allowing for a balanced cup of coffee with all its flavors fully realized. Plus, grinding your own beans gives you more control over the brewing process while allowing you to experiment with different brewing methods. For a coffee lover, investing in a burr grinder is definitely worth it! 

Can I use a blender to grind coffee beans?

Yes, you can use a blender to grind coffee beans. However, be aware that blenders are not designed for grinding and the results may be inconsistent. We recommend using an electric burr grinder instead if you want precision and consistent results.
