What You Need to Know
Pyrolysis of lignin/cellulose in charred barrel staves releases phenolic compounds (guaiacol, syringol) while residual alcohol-soluble flavorants (vanillin, lactones) migrate into foods.
Imparts dual aromatic profiles - traditional smoke notes plus barrel-derived vanilla, caramel and spice nuances.
