Some people believe that cold brew coffee is easier on the stomach than regular coffee. This is because cold brew coffee is less acidic than regular coffee. Cold brew coffee is also said to have a smoother, less bitter taste. However, there is no scientific evidence to support these claims. In fact, a study published in the Journal of Food Science found that cold brew coffee was actually more acidic than regular brewed coffee (1). So, if you’re trying to decide whether or not to switch to cold brew coffee, there’s no need to worry about your stomach – both types of coffee are perfectly safe to drink.
