Beware of the Mocha! Learn the risks no one tells you and how to avoid a kitchen explosion
The Moka coffee maker is a symbol of Italian tradition, an object that has spanned decades of history in the homes of millions of people, and is loved for its ability to prepare an intense and richly aromatic coffee, capable of awakening the senses from the very first sip. However, behind this apparent simplicity lie some risks that, if not properly addressed, can turn this everyday tool into a real source of danger. In this article, we will explore the hidden risks of the Moka pot and how to prevent them.
When can the coffee pot become dangerous?
The Moka coffee maker uses the pressure generated by steam to push hot water through ground coffee, creating an intensely flavored espresso. However, if the internal pressure exceeds safe levels, the risk of an explosion becomes real. As reported by Gambero Rosso, this can happen for several reasons:
- Clogged safety valve: The valve is designed to release excess pressure. If blocked by coffee residue or limestone, the pressure is not released properly.
- Worn gasket: A deteriorated rubber gasket can compromise the seal of the coffee maker, causing leaks or a dangerous buildup of pressure.
- Coffee ground too fine: Coffee ground too finely can clog the filter, preventing proper water flow and increasing internal pressure.
Safe mocha: the ultimate guide to risk-free coffee!
To continue to enjoy the pleasure of great homemade coffee without risk, it is essential to take care of your Moka pot. Proper maintenance not only ensures that it always tastes perfect, but also avoids dangers such as clogs, leaks or, in the most extreme cases, explosions due to excessive internal pressure. By following these simple but important precautions, you can use your Moka pot safely:
- Regular cleaning: After each use, disassemble the Moka and thoroughly rinse all its parts with warm water. Avoid harsh detergents that could leave residue and alter the taste of the coffee.
- Checking the safety valve: Periodically make sure the valve is not clogged by limescale or coffee residue. You can blow through it gently or remove any deposits with a toothpick.
- Replacing the gasket: Check the condition of the rubber gasket, which can deteriorate over time. If it appears cracked, hardened or warped, replace it to ensure a tight and secure seal.
- Choosing the right grind: Use a medium grind, suitable for Moka. Coffee that is too fine can clog the filter, preventing water from passing through and increasing internal pressure.
- Proper filling: Never exceed the maximum water level indicated in the boiler and do not over-press the coffee into the filter, to avoid a clog that could affect the proper functioning of the coffee maker.

Can a coffee pot really explode?
Although accidents are rare, the possibility of a Moka pot exploding cannot be ruled out. A tragic example is the one that occurred in April 2024, when a retired teacher in Palermo, Italy, lost her life when her Moka maker exploded. Unfortunately, these accidents are often the result of inadequate maintenance or the use of low-quality components. In fact, the use of non-original gaskets or poor materials can seriously compromise the safety of the coffee maker, putting those who use it at risk.
