Perhaps someone will correct me, but John Lovick's bottle production (actually a production of a tall glass of club soda), and Michael Ammar's are both variations of Bob Read's basic bottle production.
Tom Stone's PDF manuscript "A Toast to Charon" is a complete routine with coin productions and vanishes, which ends with the bottle production.
While reading and discussing (by email) this, I put together the following, which is a pleasantly effective construction.
Start with a bottle in position, then put a champagne glass under your armpit (for the Jardine Ellis production as detailed in Classic Secrets of Magic), then ball up a silk and put it in a fold of material in the crook of your arm.
Enter. Clap your hands and extend your right hand, causing the silk to appear in midair. Show the silk both sides, then producte the glass. Now put the glass down and use the silk to produce the bottle.
If I had a stage act this would definitely be my opener. :-)
