VEGAN FLavors and extracts
Below are links to both specific plant-based flavorings or companies selling plant-based flavorings. Note that in the case of the latter, not every product that company sells may be vegan (unless otherwise noted). If unclear, inquire with company. Answers to my own queries are noted.
