I explained how to add them a few posts back but Thierry has worked up something for you there, thank you Thierry!
Also the regular bottle's main body was textured using 'crystalMat' as its material which is already in the game. The original material for it was for an alcoholic drink and I wasn't sure I should promote that lol! If you do want the original mat for it I can always send a link for you to copy it if anyone likes. Personally, I like the crystal mat, it makes it glossy like a glass bottle should be.
