You can purchase booze at the QDC and at designated bars. All of these close during Ramadan and will not re-open until probably Sept 19 or 20.

The current line here is if you want to enter most bars you have to provide your Qatar ID (or passport which has a copy of your RP in it) - this allows the police to "track" who is entering these establishments.
