That's incorrect, and was never what our instructions said to do, even if it somehow managed to work for you before.
Please follow the instructions on https://wiki.winehq.org/Debian.
Those instructions aren't flexible, because they don't allow using generic distro name like testing. Rolling Debian setups simply point to testing, not to named releases.
That's how for example my main Debian repo is set up:
deb http://ftp.us.debian.org/debian/ testing main contrib non-free deb-src http://ftp.us.debian.org/debian/ testing main contrib non-free
deb http://security.debian.org/debian-security testing/updates main contrib non-free deb-src http://security.debian.org/debian-security testing/updates main contrib non-free
Please set up Wine repo in the similar fashion. I already opened a bug about it in the past, and Wine developers responded that it would be taken care of.
See bug 42735.
