An interesting approach, but a wine bottle has a sharply indented bottom (the Punt) that raises 1.5" to 2" at the peak, and the desired cut line is as close to the bottom as is possible. I've developed a good working technique, but enjoying a full bottle of wine before attempting a cut is a recipe for a broken bottle.... I would expect that the repeated heating of a piece of rebar and attempting to feed it down through the neck of a bottle into a pool of oil would also be a bit dicey in that condition, too, even if the punt were not an issue.

Sounds like a possible experiment for a flat bottomed jar or bottle, done where spilling a half cup of hot oil is not a problem....
