The purpose of this article is to teach people who have no previous experience how to grind coffee beans using their coffee grinder at home.
As you might guess, there’s a few simple guidelines you should follow in order to do this correctly – and you will thank yourself later as your coffee or espresso will be delicious!
Coffee Grind Size Matters
Of course, learning how to grind coffee beans yourself, whether you’re looking for a coarse French Press grind, or a finer espresso grind, can be a rewarding experience in more ways than one.
Really, there are two main rewards; one being learning a new skill, and the other benefit being fresh, delicious coffee you’ve made yourself! Plus, you save money by making coffee at home. 😀
Eventually, with practice, we know you’ll be preparing cups of black gold that can make the best bartista in town’s coffee taste like dishwater.
Well, maybe not, but at least it will put a few things into perspective where suddenly you will know if your local barista has been trained or not.
But lets not get ahead of ourselves, we still need to learn how to grind those beans.

Grind Size & Brewing Method
The main thing to know when you are about to grind coffee beans is being aware of the brewing method you will be using after the beans are ground up, because this will determine the grind size you want.
Here’s a quick video from the folks at Whole Latte Love which illustrates this point perfectly.
As you can see, there’s no one answer for how to grind. It will always depend on your brewing method.
So, depending on which of the type of brewing method you’ll be using (and there are many ways to brew), you will need to adjust grind sizes to get the results you want.
By grind size, we mean the coarseness or fineness of the grind as this picture shows us.
Best Coffee Grinders for Making Espresso At Home
Here are some great espresso grinders for home according to our editors!
For instance, will you be preparing drip coffee?
Drip coffee is made through the standard coffee maker, where ground beans are scooped into a filter, the water heats up and drips down into the carafe on the burner below.
This is ideal for higher volume of coffee. It’s your standard diner coffee.
If that’s what you’re looking for, you might want one of the best coffee grinders for drip coffee, the Capresso Infinity that we mentioned before.
Looking for something a little coarser so you can make a great French press or pourover style cup of coffee?
French press is a very convenient way to make coffee: boiled water is added to a beaker-shaped vessel, left to steep with the ground coffee.
Then the top is pressed down to the bottom to hold the grinds in place while you pour your coffee.
Pourover involves pouring hot water over the grinds and letting it steep slowly in a one-serving kind of way.
The Baratza Encore is a solid choice, as we said before.
Or perhaps espresso is what you’re after?
You’ll need a coffee grinder that is superb when it comes to find grinding, like the Rancilio Rocky.
The Importance Of Trial & Error
If you’re making coffee at home, and that’s the way you want to go, you need to consider something.
That is, even if you have a great coffee maker, and premium coffee beans, and delicious filtered water – you can still ruin your cup of coffee if the beans aren’t ground correctly.
That’s why I’m here – to prevent that from happening with a bit of education.
That said, if you’re new at coffee grinding you should expect to make a few less-than-perfect cups of coffee before getting the hang of it.
Once you’ve been through the process of how to grind coffee beans yourself a few times, you will no doubt start producing better and better results in the form of delicious cups of coffee and/or espresso!
With grinding, the goal is to expose the unique characteristics of your chosen coffee bean by preserving its essential oil and extracting its natural flavor.
It’s going to take some time to get the perfect coarseness and flavour.
You should also experiment with your preferred method of preparing coffee.
Do you enjoy the whole process?
Do you want to enact a barista’s role at home, and do the whole thing from start to finish: grinding the beans before each cup?
Do you want a whole pot of coffee to guzzle down, or would you prefer to savour one or two mugfuls?
Some people even prefer different coarseness because of the sound produced when handling the grinds.
Now, on to looking at the grind size specifications a little bit closer.

How To Grind Coffee Beans – Basic Rules
Ok, now that you’ve seen how the grinds should look, these are the some basic, yet important, rules to grinding coffee you should think about.
To start you need the best coffee grinder you can afford to get, so make sure you have that sitting on your counter before we begin.
Also, grab a bag of the freshest and best coffee beans you can get your hands on.
Besides the grinder and the beans, you’re also going to have to know how you’re going to brew your ground coffee. As we said before, different brewing methods call for different grinds, so it all depends.
Three Basic Rules For Good Grinding
However, since we can’t predict what brewing method you’ll be using, let’s just take a look at a few general rules for good grinding when it comes to coffee to start with.
- For freshness, always grind your coffee right before you brew
- Decide on your grind size and adjust your machine accordingly
- Keep your grinder clean before and after uses
Theoretically, if you can remember these three simple rules, you should be in good shape starting out. But in practice, are these rules easier said than done?
Since this is your basic beginner course on grinding coffee beans, we should now explain something we talk about at length on this site, in many of our articles.
That is, there are two types of coffee grinder: burr grinders and blade grinders.
If you’ve never ground up a bean in your life, this is pretty significant information in your coffee journey.
Before we get into the specifics of grinding the beans, we want to talk about each of these types of grinders for a minute.
If you already have your grinder plugged in and ready to go, that means you’ve already made this choice, because you will either have one type of grinder or the other sitting before you.
If you feel like skipping this next section and going straight to the section below on grind size, you’re more than welcome to do so.
Just keep in mind, that each type of grinder grinds differently, so the more you know about each kind of grinder, the better off your coffee will be. Knowledge is power!
Blade Grinder Basics
Blade grinders are usually the more inexpensive of the two types of grind, often running you $30 or less.
These grinders use blades that resemble helicopter blades and literally chop at the coffee beans until they’re ground up.
Generally speaking, you control the resultant grind size as the blade spins, and you control its speed manually.
Blade grinders are good for basic use.
In our article, “Best Coffee Grinder Under $50“, it so happens that the Krups F203 wins out as “best grinder” for its price point, because its really quite economical and handy, beating out even some popular burr grinders.
Here now are some advantages and disadvantages of blade coffee grinders.
BLADE GRINDER ADVANTAGES:
- Inexpensive – Most models are under $30
- Easy to operate – Simply push the button to pulse the blades
- Easy to clean – Simple design with one removable part
- Easy to store – Smaller size takes up less room
- Faster grind – Toss in your beans and push the button, works fast
BLADE GRINDER DISADVANTAGES:
- Inconsistent grind at times – Some beans are turned to powder and others are in chunks
- No Portion Control – You have to measure your beans for each use
- Overheats the beans – Resulting in adversely affected flavor
- Less Capable – Can’t do a fine grind as well, generally
Burr Grinder Basics
Burr grinders effectively crush or mash your fresh whole coffee beans between two pieces of metal or ceramic surfaces called burrs, rather than the old hack and slice method of blade grinders.
Burr grinders are, in most cases, far more effective than blade grinders, which is why we try to recommend burr grinders if at all possible, although this can be a bit of budgetary concern as the difference in price between a burr grinder and a blade grinder can be quite stark.
A Note About Manual Coffee Mills
Keep in mind that manual coffee mills are also considered to be burr grinders because…well, they use burrs.
They are also relatively cost effective, in the same way that blade grinders are.
The “downside”, according to some coffee fans, is that manual coffee mills (think pepper mill) are slow. We can’t argue this.
They are a lot slower compared to electric grinders, whether we’re talking about electric burr or blade grinders.
In fact, in our article “Best Coffee Grinder Under $200“, as well as “Best Coffee Grinder Under $500“, burr grinders were the only grinders considered (no blade models) and so of course burr grinders came out on top both times.
Of course, these were the electric burr grinders. The manual mills we just mentioned were featured in our article “Best Coffee Grinder Under $50“.
When you talk to any coffee buff or barista about coffee grinders, they will tell you that burr grinders are better than blade models, hands down.
There are two different types of burr you find in burr grinders that make a difference.
Flat Burr Grinder
Flat burr grinders are generally the less expensive of the two types of burr grinders.
These tend to be a little messier and noisier due to the speed of the motor and the heat it produces.
Flat burr grinders like the Baratza Vario are still great and loved by fans and it produces flavorful results, but, by and large, flat burr grinders are not quite as respected in the coffee business as conical burr grinders, though, in specific terms, it will always depend on the model.
One reason the pros go for conical burr grinders is because of the fact that conical burr grinders use gravity vs. centrifugal force. More on that momentarily.
Conical Burr Grinders
The top cone-shaped burr spins slowly in this model, which makes for a far less messy and quieter grind.
Conical grinders are great for oily (dark roasted) or flavored beans, as they are less likely to clog than flat burr grinders.
While they tend to be more expensive, the conical burr grinder is definitely worth the extra money, especially if you plan on grinding on a daily basis.
The burr on the above left is from the Breville Smart Grinder, one of our favorites.
Here is a point form list of the advantages and disadvantages of your average burr grinder, which might have either a flat or conical burr set.
BURR GRINDER ADVANTAGES:
- Grinds Evenly – Even, consistent grind
- Variety of Grind Adjustments – From fine to coarse, some even do Turkish.
- Preserves Flavor- Doesn’t overheat like a blade grinder
- Slower – A methodical and slow grind for more consistency
- Quieter – Burr grinders tend to be less noisy
BURR GRINDER DISADVANTAGES:
- More Expensive – But you get what you pay for
Flavor Extraction – How It Works
This will depend greatly on your brewing method, but we do still want to discuss extraction briefly in general.
When water (the extraction agent) makes contact with the coffee grounds it determines how much flavor the resulting brew will yield.
More contact means more flavor. The finer your coffee grounds are, the more surface there is for the water to extract the flavor.
In espresso parlance, it’s called “pulling a shot”.
Essentially, the purpose of roasting the coffee bean is to evaporate the moisture out.
The intense heat forces or squeezes water out of the bean, but also draws out its natural oils.
Coffee is actually 71% fatty acids.
We want these oils! These oils, once extracted, render the bean in an oily coating. This is what gives the bean its particular flavour in addition to its colour.
Lighter roasts will, while providing more caffeine, be less oily and lighter in flavour, while darker coffees are more oily. You can tell if beans have gone stale by a dryness.
The minute you grind the beans, you are breaking down the pieces and this means the oil seeps out more (like we described water extracting the flavour from more surface).
The best way to ensure the tastiest, most refreshing cup is to grind your beans immediately before brewing. You will notice the best quality cafes always grind your beans right before they make your drink.
That’s why the fancy cafes are addictive and that’s why we’re here to help you save some money: by doing the same tricks.
Otherwise, ground coffee may only have a real shelf life of two weeks – and that’s in a dark container away from light.
Grind Size For French Press
For other brewing methods like the famous French Press, its when the water and coffee grinds mingle together that the magic happens – and grind size matters for this!
If you are plan on doing any French Press grinding, here is an article which specifically talks about how to achieve the right grind size for the French Press and the right grinder for the job.
The coffee lover in the following video, for instance, uses the KRUPS F203 blade grinder for French Press and gets exactly what he wants out of it.
Flavor Extraction – Getting Picky
A quick note about beans: the amount of oil content in a particular bean will determine its colour. For example, more oil gives a darker colour. This affects the taste of the coffee.
Generally speaking, coffee brewed with grounds that are too coarse are going to be weak and less flavorful due to being under-extracted.
On the other hand, if the coffee is ground too fine, it can be over-extracted and taste bitter if you’re using the wrong brewing method.
In the beginning, don’t be afraid to experiment and try different grind sizes.
It’s all about finding the perfect coarseness (or fineness) to match your own personal tastes.
Above, we are just outlining some general rules but of course rules are made to be broken! Still, note that even the smallest of changes in grind size can drastically affect the taste of your final cup of coffee.
If you grind and brew on a regular basis, your taste buds are going to be leading the way!
