In cosmetics, they call that black label. Like, a little company has something made by a big company that owns the equipment and such, but the exact mix of ingredients is bespoke to that little company. There’ll be some overlap in manufacturing methods, because the big company has a way of doing things, but the specific end products can be completely different in use and feel.
That might be why AJ has the drydown sheen, but is still a different animal in a lot of other ways. 🙂
