Instant Coffee
A considerable amount of information about coffee volatiles has been obtained by detailed studies of the various stages of manufacture of instant or soluble coffee.

Soluble coffee, which is now universally accepted as a ready means of making a most acceptable beverage, is made by extracting the ground roasted beans with hot water and then removing this water either by spray drying or by the more sophisticated methods include agglomeration and aromatization which result in a final product which is readily soluble and has an odor and flavor more nearly that of freshly ground coffee.
