What is the black sediment in coffee?

The black precipitate in the coffee is the residue from grinding the coffee, which is a normal phenomenon. It may also be that the coffee is not completely dissolved. The insolubility is related to the water temperature. The solubility will be better if the water temperature is slightly higher, but the water temperature cannot exceed 80 degrees.

Different batches of products produced in large-scale industrial production will have sensory differences. These differences include: some products have coarse particles while others have fine particles. Some have strong flavors while others have weak flavors. Some products dissolve easily while others dissolve relatively slowly. There is also the amount of foam, etc. These are all normal phenomena.

If the freshly brewed coffee is too hot, you can use a coffee spoon to gently stir it in the cup to cool it down, or wait for it to cool down naturally before drinking it.

The coffee we drink daily is made from coffee beans and a variety of cooking utensils. Coffee beans refer to the kernels inside the fruit of the coffee tree, which are then roasted using appropriate methods. A standard cup of coffee should not taste bitter. A qualified barista will rigorously perform each step when making coffee, and the coffee served to the customers will have different degrees of sweetness, sourness, mellowness or cleanliness in taste.
