Why does a cold coffee taste so different from a hot one? I like my coffee either way but I gotta say that when my morning mug grows colder it starts to taste very different (and sometimes better). Just wondering what does losing its warmth do to the flavor exactly?

Something the others hadn’t noted is that a large contribution to what people call their sense of taste happens in the nose. Basically, the sense of smell is intrinsically involved. When coffee is hot, more volatile chemicals escape it via evaporation and make it into your nose, altering your perception of the flavour. As it cools, fewer chemicals are able to leave the coffee so that it winds up tasting different.
