No it's fine, I'm no expert myself. Umm, it's a black light.
Kalpa marks their bottles with a anti-counterfeit luminescent film that can only be seen under a black light.
Ever been to a rave? It's those light that make white glow like purple, etc.
If you had one you could make sure it had the markings.
