I would not do this. First, the wine probably does not have a high enough concentration of alcohol to absorb the weed efficiently. Usually the alcohol needs to be concentrated, like in vodka or Everclear. Also, I am most concerned about the idea that you would do this with a bottle of good wine. Don't go putting crazy stuff in your good wine! Just drink it and enjoy it!

Seriously though, if you uncork the wine and put something in it, it will turn to vinegar by the time you age it a month.
