Social platforms like Instagram and TikTok are full of kitchen hacks and coffee tricks, some of which go viral in days. A recent clip showing how to make a cafe latte in an Italian coffee machine has millions of views, but it sparked a wave of caution from commenters who worry about safety.
For true coffee enthusiasts, the appeal lies in a classic crema and foam. In a video by a TikTok user, milk was used instead of water in an Italian coffee machine, resulting in a creamy, rich texture that impressed many viewers.
Despite the creator’s repeated demonstrations, many viewers expressed a sense of unease. Some reported damaged coffee pots, while others claimed the machine could have exploded under different circumstances.
In the video comments, one TikToker shared a frightening anecdote: a family coffee machine exploded and caused significant kitchen damage.
Why might this happen?
These machines are not built to contain milk. Introducing milk can clog the safety valve that normally handles water pressure, potentially leading to a small explosion. Milk fat can also burn, leaving a bitter aftertaste and a lingering smell.
OCU guidance
OCU offers practical advice on making coffee with milk using an Italian coffee system:
-
First, do not follow the video steps. There are safer alternatives to achieve a creamy cup.
-
Pour the milk over the top of the coffee pot so it blends with the hot coffee as it dispenses, avoiding contact with the safety valve and reducing risk.
The main concern with this approach is not to add too much milk and to ensure the coffee level never exceeds the upper tank.
Additional tips for enjoying quality coffee
Milk can be foamed with a small hand blender. Heat the milk briefly and whisk until light and airy.
For a stronger aroma, brew coffee separately and mix it with the finished beverage. Using the ground coffee directly in the component where water typically enters can extract more flavor from the grounds, enhancing aroma and taste without increasing risk.
Espresso machines generally operate at higher pressures, which helps extract fuller flavor and more pronounced aroma.
