/\ get some of these and a 14mm downstem on eBay. 14mm is the way to go cuz you can dab with it too. Just make sure to practice drilling glass at least 10 times before you risk that beautiful bottle. Best of luck!
I used a glass/tile drill bit while it was immersed under water and then largened the hole with a dremel and and a grinding stone to get it to size. I just ordered this set of bits off amazon as the one I had was much to small and took forever to grind up to size.

Use these, use a spray bottle with water as you drill but they'll actually work. Those harbour freight bits are not designed for hardened ceramics (porcelain) and tend to heat up and burn out.
If you want to up the ante, use an M14 mount bit, they attach to your grinder and are speedy and easy, but pricy. Talking 10s or less per hole.
