Cold brew vs. Iced coffee
Coffee made in a coffee machine will have little difference in properties from hot coffee when ice is added. Cooling in this case does not affect the amount of caffeine either. With Cold Bru, everything is a little more complicated: the level of caffeine in it can be higher, however, even here a lot depends on the type of beans, the ratio of water and coffee, the type of roast, and the volume of the drink.
