Where is vanillin found?
Pure vanillin is exclusively found in vanilla beans and is never processed out of the bean pods. The value of pure vanilla comes not from the vanillin alone, but from the delicate complexity of over 400 known flavor components coming together in a unique flavor that simply cannot be duplicated. Synthesizing vanillin from vanilla beans would be like isolating a single component of an expensive and complex red wine and throwing the rest down the sink.
