Moka pot brewing: Bialetti stovetop espresso made by steam and flame.
Bialetti, Bellman, Grosche, MHW and zeroHero — the stovetop brands we've tested and stocked.
TL;DR. A moka pot uses steam pressure to push water through ground coffee on a stovetop. Bialetti's 1933 Moka Express defines the category; the Brikka adds a pressure valve.
The moka pot is the most disciplined way to make coffee without an espresso machine. Steam pushes water through finely ground coffee at around 1.5 bar, producing a small, concentrated cup with crema body. We've been stocking Bialetti's Moka Express since the early years of Coffee Parts, and the stovetop range we carry today, including the Brikka, Venus, Bellman CX25P and MHW Double Valve, has earned its place on Australian kitchens and induction cooktops.
What separates a good moka pot from a forgettable one is mostly metallurgy and pressure management. Traditional Bialetti Moka Express bodies are cast aluminium — an Italian design choice from 1933 that conducts heat fast and is light to handle on a gas hob. Aluminium is not induction-compatible, which is why Bialetti's Venus and Moon ranges are made from stainless steel for induction stoves, and the Moka Induction model uses a magnetic base laminated to an aluminium body to bridge both worlds.
The pressure side is where moka pots quietly diverge. A standard Bialetti Moka Express tops out around 1.5 bar, enough to push water through the puck but not enough to produce true espresso crema. The Bialetti Brikka and the MHW double-valve design both add a weighted valve over the spout that holds back the brew until enough pressure builds, forcing out a thicker, foamier pour. It's not nine bar, but it's the closest you get on a stove.
We've been supplying parts for these pots, including gaskets, filter plates and safety valves, for as long as we've sold them. The components wear; the bodies last decades. That's the deal with a well-made moka pot: it earns its place on the bench by outliving everything else in the kitchen.
Choosing a moka pot is mostly about three decisions: how many cups, what stove, and how strong you want the brew.
Cup size. Moka pot 'cups' are roughly 30 to 40ml each, closer to an espresso demitasse than a mug. A 3-cup Bialetti makes about 130ml of concentrated brew; a 6-cup makes about 250ml. Buy the size that matches your daily ritual. Underfilling a larger pot, leaving the basket half-empty, produces over-extracted bitter coffee. Get the size that you'll fill properly every time.
Stovetop compatibility. This is where most buying mistakes happen. Standard Bialetti Moka Express bodies are aluminium; they will not work on an induction cooktop. For induction, you need one of three options: a stainless-steel Bialetti Venus or Moon, the dedicated Bialetti Moka Induction with its magnetic laminated base, or a Bialetti Induction Plate that sits between an aluminium pot and the induction surface. Gas and electric coil stoves take any moka pot in the range.
Pressure-valved vs traditional. A classic moka pot produces a thin, espresso-style brew with light crema. A pressure-valved design like the Bialetti Brikka or the MHW Double Valve builds higher pressure before releasing, producing a thicker pour with a more substantial crema layer. If you're chasing the closest thing to espresso without an espresso machine, the valved options earn their fee. If you want the classic Italian morning, the Moka Express is what it has always been.
Grind and beans. Grind for moka pot is between espresso and pour over — a fine table salt, not a powder. Too fine and the basket clogs and pressure builds dangerously. A consistent burr grinder makes more difference than the pot itself. Our manual grinders for filter range covers the right adjustment band.
Heat control. Start on medium heat. The moment you hear the gurgling slow and a hissing splutter take over, the boiler has emptied. Pull the pot off the heat immediately. Holding it on the burner past that point is what produces the burnt, metallic taste people blame on the moka pot itself.
MHW-3Bomber, the brand behind the Double Valve Moka Pot in this range, was Official Gold Sponsor of the 2025 World Barista Championship in Milan. Coffee Parts is MHW-3Bomber's exclusive Australian distributor. zeroHero, whose M06 Mocha Pot is also in this collection, holds the iF Design Award, the Red Dot Award and the Golden Dot Design Award across its accessory range, with more than 70 patents to the brand's name. These aren't household espresso titles, but they are the design and competition pedigrees behind two of the brands you're choosing between on this page.
A moka pot rewards two upgrades more than any other: a proper grinder and clean wear parts. The moka basket holds a fixed volume of ground coffee, so dose consistency comes from grind uniformity, not from weighing in. A hand grinder tuned to a fine setting (finer than V60, coarser than espresso) gives you the punching power moka pressure needs without choking the puck. For cleaning, a soft brush and warm water is the lifetime maintenance plan. Avoid detergent on aluminium pots, since it strips the seasoning and pushes flavour towards metallic. Replacement gaskets and filter plates are stocked under manual brewing parts when the originals harden, pit or seep.
I drink from a moka pot at least twice a week. Not because I don't have an espresso machine, but because the moka pot makes a different cup — and it's a beautiful one when you respect it. My rule: a clean burr grind dialled in slightly finer than pour over, lukewarm water in the boiler so the metal doesn't roast the coffee on its way up, and pull it off the flame the second it starts spluttering. Most of what people don't like about moka pot coffee is heat, not the pot. (Pedro Lara)
Frequently Asked Questions
Can I use a moka pot on an induction cooktop? +
Standard Bialetti Moka Express pots are aluminium and won't work on an induction cooktop. For induction stoves you need either a stainless-steel model (Bialetti Venus, Moon, or the Moka Induction with its magnetic laminated base) or a Bialetti Induction Plate that sits between your aluminium pot and the cooktop surface. Gas and electric coil stoves work with every pot in the range.
What grind size do I use in a moka pot? +
Aim for finer than pour over and coarser than espresso, roughly the texture of fine table salt. Too fine and the basket clogs, raising pressure dangerously and forcing the safety valve open. Too coarse and the brew runs through under-extracted and weak. A burr grinder set one or two clicks finer than your filter setting is a reliable starting point.
Why is my moka pot coffee bitter? +
Bitterness is almost always over-extraction from heat. The boiler keeps cooking the coffee after the water has finished pushing through. Pull the pot off the heat the moment you hear the brewing slow and a hissing splutter take over, usually within a few seconds of the flow finishing. Starting with lukewarm water also shortens the time the coffee spends near boiling temperature.
What's the difference between a Bialetti Moka Express and a Brikka? +
The Moka Express produces traditional Italian stovetop coffee, thin-bodied with light crema. The Brikka adds a weighted valve over the spout that holds back the brew until higher pressure builds, releasing a thicker pour with a more substantial crema layer. Closer to espresso character, though still not the nine bar of a real espresso machine.
How many cups should I buy? +
Moka pot 'cups' are demitasse sized, roughly 30 to 40ml each. A 3-cup makes about 130ml total, a 6-cup about 250ml. Buy the size you'll fill all the way every time. Half-filling a larger pot to make less coffee produces bitter, over-extracted results. Match the pot to your daily ritual, not your largest scenario.
Can I clean a moka pot with detergent? +
For aluminium moka pots like the Moka Express, Brikka and classic models, rinse with warm water and a soft brush. Detergent strips the natural seasoning that builds up inside the boiler and basket, pushing the flavour towards metallic. Stainless models such as the Venus and Moon can take a mild detergent. Replace the rubber gasket and filter plate when they harden, pit or stop sealing cleanly.
How long does a moka pot last? +
The aluminium or stainless body lasts decades. Many of the Bialetti pots that come into our workshop are older than the people carrying them. The wear items are the rubber gasket, the filter plate, and occasionally the safety valve. We stock replacements for the full Bialetti range. With basic care, a moka pot is a multi-decade purchase, not a five-year one.
