Moka Pot Grind Size | For Delicious Velvety Stovetop Coffee
Moka Pot grind size is important to nail.
But once you get a feel for it you'll be enjoying those full bodied Stovetop brews everyday.
When I'm after a strong cup of coffee with a rich flavour, I often turn to my trusty Moka pot.
For those who haven't had the pleasure, a Moka pot is a type of stovetop espresso maker that has been a staple in Italian households since the 1930s.
It's a simple and classic method for making a robust brew, but as I've learned through experience, getting the grind size right is crucial for the perfect cup.
Finding the optimal moka pot grind size took a bit of trial and error for me.

It's all about striking a delicate balance; too fine and you risk a bitter cup, or even worse, a clogged pot.
Too coarse and the water will rush through without proper extraction, leaving you with a weak and underwhelming brew.
The Best Moka Pot Grind Size
Medium - Fine Ground Coffee
I've found that the best grind size for a Moka pot is quite fine, a bit more so than what you'd use for drip coffee, but not as powdery as what you'd grind for an espresso machine.
It should feel a bit like table salt when you rub it between your fingers.
See our grind size chart below.
It's a sweet spot that allows the water to pass through evenly and extract all the good flavours without going too quickly or causing blockages.
How to grind coffee beans for a Moka Pot
Here's my go-to method:
Select the right grinder: I personally prefer a conical burr grinder because it gives me a uniform grind size, which is absolutely key for a quality brew.
Measure your beans: I use about 20 grams of coffee club beans for my Moka pot, which serves a couple of cups. Adjust according to your Moka pot's size and your preference.
Grind your beans: I set my grinder to a medium-fine setting. If your grinder has numbers, you might start around 14-16 on a scale where 1 is the finest and go from there.
Inspect the grind: The particles should be finer than sand, but not as fine as powdered sugar. About 1/32 inch is what you're shooting for.
A quick tip: freshly ground beans make a world of difference, so I always grind mine just before brewing.
There's something really satisfying about hearing those beans crack and crush, knowing a stellar cup of coffee isn't far behind.
What's the ideal coarseness for a Moka pot brew?
For my Moka pot, I've discovered that getting the grind size just right is crucial for a beautifully robust cup of coffee.
It should be slightly finer than what you'd use for a drip filter, yet not as powdery as an espresso grind.
In my experience, the perfect grind looks a bit like table salt not the big flakes you sprinkle on your chips, but the small grains you'd find in a salt shaker.
If the coffee is too fine, it can lead to over-extraction a rather bitter surprise!
Too coarse, and the water will rush through without picking up enough flavour, giving me a rather weak brew.
I've found that using a flat burr or conical burr grinder is the secret to achieving that magic consistency. They crush the beans uniformly, giving me just the right grind every time.
Here's a quick checklist I use:
Check the grind: Aim for a medium-fine grind similar to table salt.
Uniformity: Ensure the grind is consistent; irregular sizes can ruin the brew.
Adjust if needed: If the coffee brews too fast, go finer; if it's too slow, opt for a bit coarser.
By minding these steps, I get to enjoy the full-bodied, rich coffee that my Moka pot is capable of. It took a bit of trial and error, but trust me, it's worth the effort!
Experience the best coffee in the World
How does the grind size impact a Moka pot's coffee flavour?
When I'm brewing coffee with my Moka pot, the grind size is critical for dictating the flavour and strength of the end product.
If I use a grind that's too coarse, the hot water jets through without extracting those rich, desirable flavours; the coffee often ends up weak and underwhelming.
On the other hand, a grind that's too fine can be a disaster. It might clog the filter, leading to an over-extraction where the coffee becomes bitter, even astringent.
It's a fine balance to strike, but I've found that a consistency slightly finer than table salt is just right.

Here's what seems to be the consensus:
Too Coarse: Under-extracted, flat, and lacking in depth.
Just Right: Balanced, rich, and full-flavoured; akin to the experience of a traditional espresso.
Too Fine: Over-extracted, bitter, and could potentially damage the Moka pot through increased pressure.
An even and consistent grind is paramount, so a conical burr grinder is usually my tool of choice for achieving the perfect granule size for my Moka pot brews.
Can I get away with using espresso grind in my Moka pot?
When I first got my Moka pot, I didn't realise that the grind size could vastly affect the brew. I wondered if using my usual espresso grind would work. It turns out, this might not be the best idea.
Here's the lowdown: Espresso grounds are much finer than what's ideal for a Moka pot. Since Moka pots brew coffee by passing water through grounds using steam pressure, an espresso grind can cause issues. It's a bit too fine, which could lead to a clogged filter or over-extraction.
Frequently Asked Questions
When it comes to Moka pot brewing, I've seen many coffee lovers getting befuddled by the nuances of grind size and ratios. Allow me to clear up some common queries.
Is there a difference between grind size for espresso and Moka pot coffee?
Absolutely, there is. Despite both requiring a fine grind, the Moka pot prefers it a bit coarser than espresso. Think fine, but not powdery—the consistency should be more like table salt, whereas espresso calls for a texture akin to powdered sugar.
What coffee-to-water ratio should I aim for in my Moka pot?
I've found the ideal coffee-to-water ratio hovers around 1:7. That translates to 1 gram of coffee for every 7 millilitres of water. By sticking to this ratio, I ensure my Moka pot brew is robust and flavourful without being over-extracted.
Could I use a pre-ground coffee for Moka brewing, or should I grind fresh?
While you can use pre-ground coffee, to get the best from my Moka pot, I always opt for freshly ground beans. The grind size for Moka pots is typically slightly coarser than espresso, so buying pre-ground espresso will often result in a sub-optimal brew. Fresh grinding right before brewing gives me that perfect granularity and a fresher cup.
