In a well equipped laboratory, there are many methods of doing the job. These include reverse osmosis, fractional crystallisation. and freeze distillation It would be unethical of me to provide details of the methods on a public forum. Besides, certain toxic alcohols such as methanol tend to end up in alcohol as well especially when fractionally crystallising whisky or brandy/cognac.
Finally, I would add that if you are in the USA and you are caught removing alcohol from wine, it will lead to an inevitable period of incarceration. Licences are required to perform this function and the licences are very strictly controlled. In the UK, the penalties are similar.
I strongly suggest you put the idea out of your mind.
