No, all bourbon, regardless of whether it's a flagship, small-batch, or single barrel, gets all of its flavors from the charring found on the brand-new oak barrels. It's technically illegal to add any type of flavoring to bourbon. This means that you can cook with it and drink it without worrying about ingesting any type of chemicals. However, some distilleries use new techniques where they finish the bourbon in brandy or sherry barrels. If this occurs, the bourbon will have unregulated techniques listed clearly on the label.
