What is the purpose of adding milk to coffee?

Adding milk to coffee primarily serves to enhance flavor, texture, and balance acidity. When milk is introduced, it adds creaminess and richness, which can complement and elevate the coffee's natural flavors. This combination often results in a smoother drinking experience, making the coffee feel more indulgent.

Furthermore, milk can help to balance the acidity of certain coffee blends, which might otherwise be too sharp or overpowering for some palates. This balance is particularly relevant for darker roasts that can sometimes have bold, bitter flavors that are softened by the addition of milk.

While milk can impact the temperature by cooling a hot beverage, that is not its primary purpose. Similarly, it does not affect the caffeine content or alter the brewing time, which are not relevant considerations when looking at the key advantages of incorporating milk into coffee.
