I’ll start with a confession: the Moka Pot isn’t a brewer I reach for very often myself.

But plenty of What’s Bean Grinding customers do.

And when someone buys a bag ground for Moka Pot, I want to be able to point them towards a method that gets the best from it rather than leaving them with the traditional fill it, put it on the hob and wait for it to start making angry noises approach.

Predictably, this brings us back to James Hoffmann.

His Ultimate Moka Pot Technique is less about following an exact recipe to the second and more about controlling heat, flow and extraction so you get a rich, concentrated coffee without the harsh, burnt character Moka Pots can sometimes produce.

If you just want to brew, use the interactive guide above.

If you want to understand what is happening and how to adjust it for your coffee, read on.

Watch James Hoffmann’s Original Moka Pot Guide

Unlike the French Press and V60 guides, there isn’t one perfect set of numbers here.

Moka Pots come in different sizes, different materials and behave differently on different hobs. Roast level also changes how you might want to approach the brew.

So think of this as a technique rather than a stopwatch recipe.

Who is James Hoffmann?

If you’ve read the other Brew Guides, you may have noticed James Hoffmann crops up rather often.

There’s a reason for that.

He is a World Barista Champion, co-founder of Square Mile Coffee Roasters and author of The World Atlas of Coffee, but more importantly for these guides, he has a habit of testing the assumptions that surround familiar brewing methods.

The Moka Pot series is a particularly good example.

Rather than simply repeating the traditional rules, he looks at what changing water temperature, grind size, heat and flow actually does to the brew.

What’s Different About This Method?

Traditional Moka Pot advice is often something like:

Fill the base.
Fill the basket.
Put it on the hob.
Wait for it to gurgle.

The problem is that the violent sputtering at the end of a Moka Pot brew is exactly what we would rather avoid.

Hoffmann’s approach is built around keeping the extraction controlled.

The basic idea is:

1. Start with hot water.

2. Fill the basket properly, but don't tamp it.

3. Use controlled heat.

4. Watch the coffee as it begins to flow.

5. Reduce the heat and keep that flow steady.

6. Stop the brew before it enters the aggressive sputtering stage.

It requires a little more attention than simply leaving the pot on the stove, but not much.

What You’ll Need

• A Moka Pot

• Freshly roasted coffee

• Burr grinder, if you're grinding at home

• Kettle

• Hob

• Tea towel or oven glove

• Cold running water

• Optional AeroPress paper filter if one fits your Moka Pot

You don't necessarily need scales for the coffee itself.

The basket gives you a useful guide to dose: fill it evenly, level it, and don't compress the grounds.

The Starting Recipe

Because Moka Pots vary in size, I wouldn't give you a fixed dose such as 18g and pretend it applies to everyone.

Instead:

• Coffee: fill the basket level

• Grind: fine to medium-fine, but coarser than espresso

• Water: freshly boiled

• Basket: full and level, not tamped

• Heat: controlled rather than aggressive

• Lid: open while brewing so you can see what is happening

For lighter coffees, filling the boiler close to the maximum safe level gives you more water to work with and can help extraction.

For darker coffees, you may find that slightly less water works better because they extract more easily.

Never cover or fill above the safety valve.

Step-by-Step Guide

Step 1: Boil the water

Start by boiling your water separately in a kettle.

This means the Moka Pot spends less time sitting on the hob while everything slowly heats up.

Pour the hot water into the lower chamber.

For the lighter coffees I tend to roast, I would start close to the maximum fill level, while making absolutely sure the safety valve remains clear.

Be careful here.

The base is now full of very hot water and will become hot to handle.

Step 2: Fill the coffee basket

Fill the basket with freshly ground coffee.

Level the surface so the coffee is distributed reasonably evenly.

Don't tamp it.

This isn't an espresso machine and we don't want to create a tightly compressed puck for the water to fight its way through.

If you want to experiment later, an AeroPress paper filter can also be placed above the coffee before assembly. This can produce a slightly cleaner cup, but it isn't essential.

Step 3: Assemble the Moka Pot

Drop the basket into the base.

Use a towel or oven glove to hold the hot lower chamber, then screw the top on securely.

Make sure the seal is good.

A poor seal means pressure can escape where it shouldn't, which can cause all sorts of odd brewing behaviour.

Step 4: Put it on the hob

Place the Moka Pot on the hob with the lid open.

That last bit matters.

We're going to use what the coffee is doing as our guide.

Use enough heat to get the brew moving without trying to launch it through the chimney at high speed.

Now watch.

Step 5: Look for the first coffee

Eventually coffee will begin appearing from the central column.

This is the important bit.

You're looking for a smooth, controlled stream.

Once the coffee starts flowing, reduce the heat as much as you can while keeping that flow going.

Depending on your hob, that might mean turning the heat right down, switching it off, or moving the pot partly away from the heat.

You're managing momentum now rather than simply continuing to cook the base.

What Should the Flow Look Like?

Think steady and controlled, rather than explosive.

If coffee shoots out quickly and starts bubbling aggressively, there is too much energy going into the system.

If it barely moves or repeatedly stops, you may not have enough.

This is one reason an exact timer is less useful for Moka Pot than it is for V60.

Watch the coffee, not just the clock.

Step 6: Stop Before the Sputter

Towards the end of the brew, the stream will begin to change.

It may become paler, less stable and start heading towards the familiar Moka Pot gurgle.

That's your cue.

Remove the brewer from the heat before the full sputtering phase takes over.

Hoffmann's experiments showed that this late part of the brew is something worth avoiding rather than eagerly waiting for.

Step 7: Cool the Base

To stop the brewing process quickly, cool the lower chamber.

You can carefully run the base under cold water.

The aim is simply to remove enough heat that it stops pushing increasingly hot water and steam through the coffee.

Don't flood the top of the brewer. You're cooling the base.

Step 8: Pour and Enjoy

Give the coffee in the upper chamber a gentle stir before pouring.

Then serve.

Moka Pot coffee is naturally much more concentrated than a V60 or French Press.

You can drink it as it is, add milk, or dilute it with a little hot water if you prefer something closer to a longer cup.

There isn't a correct answer here.

Dial It In

This is where the method becomes useful rather than simply being a set of instructions.

It tastes sharp or sour

Try grinding a little finer.

With lighter roasted coffee in particular, you may need more extraction than you first expect from a Moka Pot.

It tastes bitter, harsh or drying

Try going slightly coarser.

Also look at the end of your brew.

If you're allowing the pot to violently sputter for several seconds, fix that before making lots of other changes.

Coffee comes out far too quickly

Reduce the heat.

A Moka Pot isn't improved by getting the coffee upstairs as quickly as possible.

The flow keeps stopping

You may have reduced the heat too aggressively.

Add just enough heat to maintain a smooth flow.

A Quick Moka Pot Check

Before changing the grind, ask yourself:

Did the coffee come out smoothly?

If it raced and sputtered, work on the heat.

If the flow looked good but the cup still tasted wrong, then start adjusting the grind.

That separation is useful.

Otherwise you can easily grind coarser to fix bitterness that was actually caused by blasting the pot with far too much heat.

Light Roast vs Dark Roast

This is particularly relevant to What’s Bean Grinding because most of the coffees I roast sit towards the lighter end of the spectrum.

Lighter coffee generally needs more help extracting.

That can mean:

• grinding a little finer

• using more water in the boiler

• allowing a higher brewing temperature

A darker roast extracts more readily, so you may want to go a little coarser or use slightly less water.

Again, don't change everything at once.

Start somewhere sensible, taste it, and make one adjustment.

What About an AeroPress Filter?

This is an optional extra rather than part of the fundamental method.

If a suitable paper filter fits underneath the upper filter plate, you can use one to catch more fine particles.

That can give you a slightly cleaner cup.

I'd try the Moka Pot without one first.

Once you've got the basic brew working well, experiment and see which version you prefer.

My Take

This one is slightly different from the other Brew Guides because I'm not going to pretend the Moka Pot is something I use every morning.

It isn't.

But plenty of people who buy my coffee do use one, and I completely understand why.

They're inexpensive, virtually indestructible, don't need a huge amount of equipment and make a wonderfully intense cup of coffee.

I also think Hoffmann's approach makes the brewer much more interesting.

Instead of treating the inevitable bubbling and spluttering as part of the Moka Pot experience, you start thinking about controlling the flow.

That makes sense to me.

And it makes Moka Pot brewing feel much less like putting something on the stove and hoping for the best.

Final Thoughts

The biggest lesson from James Hoffmann's Moka Pot technique isn't a particular number on a timer.

It's control.

Start with hot water.

Don't tamp the coffee.

Watch the flow.

Reduce the heat once the coffee starts appearing.

And stop the brew before your Moka Pot starts angrily announcing that breakfast is ready.

Once you can reproduce that, start playing with grind size and see what your coffee does.

If you want something to experiment with, have a look at the freshly roasted coffees in the shop and choose Moka Pot as the grind option if you'd like me to grind it for you.

Then brew it, taste it, tweak it, and see where it takes you.
