The bottle has a backside to it with ingredients and more info you can see in this turnaround render 
I crammed all parts of the dirty glass into one material and the shader graph did grow quite a bit …

nice work !
Wow! That’s quite a bit of [visual …] programming to finally achieve that bottle! But, you clearly did it.
I especially like the first bottle, because it is not full. You have a very plausible spattering of stuff on the inside of the top of the bottle. The bottle cap also looks great, along with the bottle itself.
Wow that’s impressive! How long have you been using blender? That node setup is intense and a bit over whelming. It awesome!
Wow, I have to say that is VERY realistic. Well done!
thanks, I’m glad you like that model and render.
@Jasonbadum started in 2016 and did some random experimenting while still doing 2D, but I really got into it more in 2018/2019. And the 2D experience helps, the logo and the whole print on the bottle is designed by me.
the huge nodesetup is a glass texture and a paint on glass texture and another texture as mixfactor and a lot of smudges and fingerprints mixed in… it’s not that complicated but rather huge 
I featured you on BlenderNation, have a great weekend!
