Scientists say hot brewed coffee is better for you than iced because it has higher levels of antioxidants. After comparing the two, chemists at Philadelphia and Thomas Jefferson Universities say the quickly heating-up process for hot coffee creates more ‘total titratable acids’. Those acids help to pump oxygen around the body. The fact that cold brewed coffee is brewed over hours, using room temperature water, deprives it of that extra health kick. Whats more, the team found there is little merit to the widespread claims that cold brew is less acidic than an americano: in fact their pH levels are almost identical. Americano is a type of coffee drink prepared by diluting an espresso with hot water, giving it a similar strength to, but different flavor from traditionally brewed coffee.
