果汁, unless you make yourself, by putting fresh fruits into a blender to make juice out of them, if you buy packages of 果汁, they are all pasteurized, "killing off" all vitamins and flavor, and afterwards putting in sugar(lots of sugar) and artificial flavor again; saw this out of a program in Discovery Channel, so never drink 果汁 from packages!
on the side, there are packages of various types of drinks, such as 菊花茶, there is some sort of taste, not sure what it is! if you make 菊花茶 from 菊花, it tastes different!
