"Flavoring derived from condensing real wood smoke."
"Natural" here describes the source (actual smoke) rather than a safer process — smoke itself, from any combustion source, contains polycyclic aromatic hydrocarbons (PAHs), some of which are established carcinogens. Being derived from real smoke doesn't remove that chemistry; it's the same category of concern as artificial smoke flavor, just from a different starting point.
A meaningful red flag: an unnamed source, heavy processing into a by-product or digest form, or documented regulatory scrutiny in at least one country. -4 pts deducted.
