It shouldn't be possible to produce methanol by distilling store bought wine because it shouldn't have any in it right?

It should only contain ethanol right? Otherwise you would get methanol poisoning from drinking it in the first place before distilling? 

Wine can contain trace amounts of methanol. Methanol is a product of pectin fermentation. Pectin is found in fruit, i.e grapes. The amount present in wine is not sufficient to be lethal, unless you drink a few thousand gallons of wine, and you'd be dead from ethanol poisoning long before the methanol got you.

You're very unlikely to distill methanol, and do think about this: drinking distilled wine will give you no more methanol than drinking the undistilled bottle anyway.
