Bialetti Kitty Review: The Classic Moka Pot Design, Rebuilt in Stainless Steel

The Bialetti Kitty is a six-cup stovetop espresso maker made of stainless steel, from the Italian company that popularized the moka pot with its aluminum Moka Express in 1933. It keeps the classic three-part design (a boiler for water, a funnel for the grounds and a collector on top) but swaps aluminum for steel and adds a rounder shape with a Bakelite handle. This Bialetti Kitty review is for anyone choosing between a stainless moka pot, a traditional aluminum one or an electric espresso machine. Ivan, our editor, bought the Kitty (model 06812) with his own money in 2022. His first-hand notes will be added to the page separately, so the analysis below relies on Bialetti's published guidance, the verified listing and well-established moka brewing technique.

The short answer: the Kitty is a sound choice for gas, electric and ceramic stoves if you want strong coffee with no electronics and easier cleaning than aluminum allows. Two details on the listing deserve a second look before you order: induction isn't listed for this model, and Bialetti's own care advice rules out the dishwasher.

Bialetti Kitty at a glance

A moka pot works by heating water in a sealed boiler until steam pressure pushes it up through a bed of ground coffee and into the collector. The Kitty does nothing exotic with that principle. What sets it apart from Bialetti's best-known pot is the material, and the material changes how you heat it, clean it and store it.

How much coffee the 6-cup Kitty really makes

Bialetti sizes its pots in espresso-style demitasse cups, not mugs. Reference summaries of moka pot sizes put one of those cups at roughly 1.4 to 2 fl oz (40 to 60 ml). The Kitty's listing gives about 12 fl oz in total for six cups, so about 2 fl oz each. Some retailers quote 300 ml (about 10 fl oz) for the six-cup size instead; the real yield depends on how close to the valve you fill the boiler and how much liquid stays in the grounds.

In practice, one brew gives you:

• One person: a large, very strong serving, or two moderate ones.
• Two or three people: an espresso-strength serving each, or the base for cappuccino-style drinks with milk you heat separately.
• Americano-style mugs: about 2 to 3 fl oz of moka coffee topped with hot water per mug.

The design also means the Kitty wants to be full. Bialetti's guidance is to use full measures of both water and coffee; a half-filled funnel lets water rush through a loose bed of grounds and tastes thin and sour. If you usually want one small cup, a smaller Kitty (retailers list several sizes) or any three-cup pot makes more sense than underfilling the six-cup.

Stainless steel vs aluminum: what the Kitty changes

Most moka pots, including Bialetti's own Moka Express, are aluminum. The Kitty's steel body changes four things.

Heat behavior. Aluminum conducts heat more than ten times better than stainless steel, so an aluminum boiler warms quickly and evenly. Steel heats more slowly and can run hotter where the flame or element touches it. The practical answer is moderate heat, a burner no wider than the base, and a little patience.

Cleaning rules. Bialetti tells owners of the aluminum Moka Express to rinse it with plain water only: no detergent, and no dishwasher, which Bialetti says can damage the pot and alter the taste of the coffee. For its stainless models, Bialetti's New Zealand care guide allows a mild detergent. That alone makes the Kitty easier to keep fresh, especially if you dislike the coffee film aluminum pots depend on.

Corrosion. Aluminum oxidizes, especially when it's put away wet or washed with harsh detergents, leaving a chalky white or gray layer. Stainless steel resists that, although Bialetti still says to dry every part before reassembling.

Taste and the patina debate. Aluminum fans argue that the coffee oils building up on the metal round off the flavor. Stainless steel doesn't hold that layer the same way, and many people prefer its more neutral result. Both are common food-contact materials for cookware sold in the US and Canada, and Bialetti frames its aluminum cleaning rules around taste and damage to the pot. If you have a specific health concern about aluminum, talk to your doctor. The choice comes down to heat, cleaning and taste.

Bialetti Kitty induction compatibility: what Bialetti says

This is where the Kitty needs care. The current listing for model 06812 names gas, electric and ceramic stoves. It doesn't name induction.

Bialetti's New Zealand brewing guide says all of its stovetop pots work on gas, electric and ceramic hobs, and that only the stainless steel models work on induction. Retailers in some markets also sell a Bialetti model called Kitty Induction. But stainless steel isn't automatically induction-ready. Induction cooktops heat magnetic metal, and 18/10 stainless steel, the grade Whole Latte Love lists for this pot, is generally non-magnetic. Induction-ready steel cookware uses a magnetic grade of steel in the base.

We couldn't find a Bialetti page confirming that the 06812 on the US listing has a magnetic base. Before you count on it for induction:

1. Hold a fridge magnet to the bottom of the boiler. If it grips firmly, the cooktop should detect the pot.
2. Check your cooktop's minimum pan size. Small moka bases can fall below the detection threshold, and Bialetti advises checking the cooktop manual.
3. Use low to medium power. Bialetti warns that induction overheats a moka pot quickly on high settings.

If the magnet doesn't stick, a steel induction adapter plate is the workaround. Bialetti sells one for its aluminum pots; it adds heat-up time but lets a non-magnetic pot work on an induction hob.

Bialetti Kitty dishwasher question: listing vs maker

The listing says the Kitty's parts are dishwasher safe, and at least one US specialty retailer says the same. Bialetti's own care guide, published on its New Zealand site, says its stovetop coffee makers must not go in the dishwasher. When the maker and a listing disagree, we follow the maker.

There are practical reasons too. Dishwasher detergent is alkaline and mildly abrasive, which dulls polished steel; long hot cycles age the rubber gasket faster; and the Bakelite handle is the part least likely to enjoy repeated heat and water. Hand washing takes a minute:

• Let the pot cool, unscrew it and knock out the grounds.
• Wash the boiler, funnel and collector in warm water with a drop of mild detergent, which Bialetti allows on stainless steel.
• Use a soft brush on the filter plate and inside the collector's central column, where coffee residue builds up.
• Rinse well and dry every part with a towel. Store the pot apart, or loosely assembled, so air can circulate.

Skip steel wool and abrasive powders. For the polished outside, Bialetti suggests a liquid chrome polish.

Handle, safety valve and build details

The handle. Bakelite is a heat-resistant phenolic resin, which is why it has been on moka pots for decades. It can still crack if you use it as a lever, and Bialetti specifically warns against holding the handle while unscrewing the pot. Grip the two metal halves instead, with a towel if the pot is warm. On gas, keep the flame under the base; a flame that licks up the side will scorch the handle.

The safety valve. The small valve on the side of the boiler releases pressure if the coffee bed or filter is blocked. Never fill water above it; Bialetti says the water should sit just below the valve. If the valve hisses during brewing, the usual causes are coffee ground too fine, coffee pressed into the funnel, or a clogged filter plate.

The wear parts. The rubber ring and perforated steel plate under the collector are what keep the pot sealed. Bialetti sells a ring and filter pack for its stainless Venus, Musa and Kitty pots, plus replacement funnels, sized by cup count. That's a real advantage over lesser-known brands that publish no spare parts at all.

How to use the Bialetti Kitty, step by step

1. First use. Wash all the parts in warm water. Bialetti recommends throwing away the first two or three brews.
2. Grind. Medium-fine: gritty between your fingers, not powdery. Bialetti notes that store-bought espresso grind is often too fine for a moka pot and can block it. Slightly finer than drip coffee is a good starting point.
3. Water. Fill the boiler to just below the safety valve. Bialetti's instructions call for room-temperature water. A widely used alternative is to start with just-boiled water, which shortens the time the grounds sit over the heat and reduces the cooked, bitter edge moka coffee can pick up. If you do that, hold the hot boiler with a towel while assembling.
4. Coffee. Fill the funnel completely and level it with a finger. Don't tamp; Bialetti is explicit about it. Brush any grounds off the rim.
5. Assemble. Screw the top on firmly, holding the metal bodies, not the handle.
6. Heat. Low to medium. On gas, keep the flame under the base; on an electric coil, use a burner no larger than the base.
7. Watch. Bialetti expects about 3 to 6 minutes, depending on pot size and heat. The coffee should rise in a steady, dark stream.
8. Stop on time. When the stream turns pale and starts to sputter, take the pot off the heat. Bialetti says not to let the coffee boil. Running the base under cold water stops the brew quickly.
9. Stir and serve. The first coffee out is stronger than the last, so stir it in the collector before pouring.

Gasket and filter maintenance: keeping the Kitty sealed

Most moka pot problems come down to the seal between the boiler and the collector. Signs the gasket needs attention:

• Coffee or steam escaping around the threads while it brews.
• A ring that looks flattened, cracked or hard, or that has shrunk away from the edge of its groove.
• Having to screw the pot much tighter than before to stop leaks.

Before you replace anything, rule out the easy causes: grounds on the funnel rim, water above the valve, or a pot that isn't fully screwed shut.

To replace the ring and filter plate:

1. Unscrew the collector and turn it upside down.
2. Pry out the old gasket with a blunt tool, working around the edge, then lift out the filter plate.
3. Clean the groove thoroughly; old coffee oil stops a new ring from seating flat.
4. Fit the filter plate first, then press the new gasket evenly into the groove all the way around.
5. Brew a batch or two and pour them away, since a new ring can add a rubbery taste at first.

Bialetti doesn't give a fixed replacement interval; its care guide simply says to check the ring, filter plate and funnel for wear and replace them as needed. A quick look every few months is enough. Order by cup count, because Bialetti sizes these parts to the pot.

Hard water leaves white scale inside the boiler over time. Bialetti's fix is to scrub with warm water and white vinegar, then rinse and dry thoroughly. Clean the inside of the collector's column now and then as well; it's the spot most people miss.

Bialetti Kitty vs WALDWERK, De'Longhi EC155 and the Moka Express

Ivan bought two other coffee makers we cover. The WALDWERK moka pot is the closest rival. Its current listing, which has been revised since Ivan bought his, describes a stainless steel pot, a little smaller at 10 oz, with an oak handle and induction among its listed stovetops. The De'Longhi EC155 is a different category: an electric pump machine that brews espresso-style shots and steams milk.

Choose the Kitty over the WALDWERK if you brew for two or three, cook on gas or electric, and want a maker with documented spare parts. Choose the WALDWERK if induction is non-negotiable or you prefer wood in the hand. Choose the EC155 if milk drinks are the point.

Against Bialetti's aluminum Moka Express, compared on paper: the Moka Express heats faster and more evenly, usually sits in a lower price tier and keeps the original design, but Bialetti says to rinse it with water only, and it works on induction only with Bialetti's adapter plate. The Kitty asks for a bit more heat control in exchange for simpler cleaning and steel that won't oxidize. For the rest of our coffee and grill gear, see the Kitchen & Grill section.

Who should buy the Bialetti Kitty

• Owners of gas, electric or ceramic cooktops who want strong coffee without an appliance on the counter.
• Households of two or three who drink coffee with milk or diluted with hot water.
• Anyone who has given up on an aluminum pot's water-only cleaning rule.
• Buyers who value a brand that sells spare parts for the exact model.

Who should skip it

• Induction-only kitchens, unless a magnet test confirms the base works or you don't mind an adapter plate.
• Espresso purists. Moka coffee is strong, but it isn't 9-bar espresso and has no real crema.
• Households where everything goes in the dishwasher.
• Solo drinkers who want one small cup at a time; a smaller size suits them better.

Bialetti Kitty tips and common mistakes

• Don't overfill. Water above the valve makes weaker, boiled-tasting coffee and can make the valve vent.
• Don't tamp or heap. A level, loosely filled funnel is the target; a domed mound of coffee gets crushed when you screw the pot shut.
• Keep the heat moderate. A roaring flame scorches the coffee and the handle.
• Pull it early. The last sputtering ounces are the most bitter, so stop when the stream turns pale.
• Dry it completely. A pot stored screwed shut and damp traps stale odors.
• Replace the gasket before it fails. A worn ring leaks steam, which means weaker coffee and a messy stovetop.
• Add a frother if you want milk drinks. The Kitty doesn't steam milk; a separate frother or a small saucepan does.

Final verdict

The Bialetti Kitty takes the moka pot design Bialetti made famous and rebuilds it in stainless steel, with all the trade-offs that implies. You get a pot that tolerates mild detergent, doesn't oxidize, makes about 12 fl oz of strong coffee per brew and can be kept sealed for years with Bialetti's own spare rings and filters. You give up some of aluminum's even heating, so moderate heat and attention matter more.

Two points stop this Bialetti Kitty review from being an unconditional yes. Induction isn't listed for the 06812, so induction owners should magnet-test the base or plan on an adapter. And although the listing says dishwasher safe, Bialetti says hand wash, which is the advice to follow. If you cook on gas, electric or ceramic and want a well-supported stainless moka pot, the Kitty is an easy pot to recommend. Ivan bought his in 2022, and his own notes will be added here once they're written up.
