Wood Smoke and Charred Wood

Wood smoke delivers phenolic flavors identical to those found in spices — vanillin (vanilla), eugenol (cloves), guaiacol (smoky warmth) — because wood’s structural lignin is itself a massive phenolic polymer. When heat breaks it apart, the fragments are the same small molecules that define clove and vanilla aroma. This shared chemistry explains why smoked foods pair so naturally with spice-heavy cuisines.

Wood composition

Wood is built from three primary materials, each contributing different flavor compounds when burned:
