Induction compatible moka pots

Induction hobs heat by inducing a current in the pan itself, which only works if the base is ferromagnetic. Aluminium is not, and the classic moka pot is aluminium. So the first question about a stovetop brewer on an induction kitchen is not how it brews but whether it will heat at all.

The magnet test settles it in two seconds

If a fridge magnet sticks firmly to the base, the hob will drive it. If it slides off, it will not. That applies to moka pots, to cezves and to stovetop kettles alike, and it is more reliable than the packaging, which often says "induction compatible" about a pot with a thin steel disc that works poorly.

Steel, or aluminium with a bonded base

Two designs qualify. A fully stainless pot works everywhere and is heavier, more durable and usually more expensive. An aluminium pot with a steel plate bonded into the base keeps the classic body and the lighter weight. The bonded kind is the one to inspect: a plate that is genuinely bonded is fine, and one that is a loose disc rattling in a recess is a pot that will heat unevenly and eventually delaminate.

Small bases and small hobs

Many induction hobs will not detect a pan under about 12cm, and a three-cup moka pot can be smaller than that. Check the minimum pan size your hob states before buying the smallest pot in a range, because a brewer the hob refuses to see is a brewer you cannot use.

An interface disc is a workaround, not a fix

You can buy a steel disc that sits between hob and pot. It works, and it wastes the efficiency and control that made induction worth having: the disc heats, then the pot heats from the disc, so you are back to a slow hot plate. Fine occasionally, poor as a permanent arrangement. How to use a moka pot without burning the coffee matters more once the heat source is sorted, because control of the heat is most of the technique.
