2. Another possible reason for coffee foaming is that milk is added to coffee powder, which is easy to produce milk bubbles after brewing.
To sum up, coffee foaming is generally a normal phenomenon, not because of deterioration or other circumstances, so you can safely drink it.
Is coffee foam drinkable?
Can drink.
From the last question, we can know that the foam produced in the process of coffee brewing is generally produced by coffee fat formed in the process of extraction, and it is also possible that dairy products are added to it to form milk bubbles. When brewed with hot water, these bubbles will float on the surface of coffee.
The main ingredients of these foams are vegetable oil, protein and sugar, which can be drunk. Of course, if you don't like the smell of this foam, you can also brush it off with a spoon before drinking.
