I learned this in this list but reading manual page of apt-get (8)
...
--default-release
This option controls the default input to the policy engine, it
creates a default pin at priority 990 using the specified
release string. The preferences file may further override this
setting. In short, this option lets you have simple control over
which distribution packages will be retrieved from. Some common
examples might be -t '2.1*' or -t unstable. Configuration Item:
APT::Default-Release
This is where it is documented. Tricky :-)
