There are deliberate differences in chocolate composition for chocolate bars in different parts of the world for climate reasons. Take a European chocolate bar to India in the summer: it will be a gooey mess (as I discovered for myself). So the "same" bar manufactured for Indian markets (for example) has a higher melting temperature than those made for European markets. This obviously introduces taste and consistency differences.
