Installing latest stable version of wine is only possible and safe via deb repository on 32 bit Debian archtecture.
Whether not sure about your Debian architecture run:
linux:~# dpkg --add-architecture i386
To install latest unstable version of wine which though unstable is often much useful to its stable predecessors add wine-unstable repository
linux:~# wget -q -O- http://www.tataranovich.com/tataranovich.asc | apt-key add -
Finally install / update (whether installed) with:
linux:~# apt-get update
linux:~# apt-get --yes install wine-unstable:i386
Enjoy ! 🙂
