Iced coffee is a type of cold beverage made from brewed coffee and ice. Cafes have started to feature iced coffee as an option in lieu of hot java, leading to its surging popularity.

Potential health risks

One should exercise caution when imbibing hot beverages such as heated-up iced coffees, as they can potentially cause burns or exacerbate acidity in the mouth and lead to sores if consumed regularly. Thus, it is prudent to allow the drink to cool before partaking of it in order to savor its taste without any potential risk.
