Here's an interesting note about USDA labeling policy (in case anyone's interested in that sort of thing).
Even though the commercial process shown in the video is using liquid smoke only, the USDA still considers the product to be smoked (by means of aqueous smoke). It can be labeled as: Smoked, Hickory-Smoked, etc. but the ingredient list must include "Natural Smoke Flavoring," and it cannot be labeled as "Naturally Smoked" (which would be vaporous smoke).
