Uninstall a program installed with Wine

Type in a terminal wine uninstaller will give you access to the built in Add/Remove tool from wine. From there you can uninstall a program you have installed in a bottle.

To completely remove the bottle for your user (and thus remove everything from a wine bottle and start again) you can open a terminal and type rm -rf ~/.wine or as an alternative open Nautilus and in your home folder press Ctrl+H, locate the .wine folder and delete it. wine will create a new folder next time you try to use it.
