Did Brian ever actually drink guava juice in the canon?

[just-a-void.livejournal.com]

I have been reading a lot of QaF fic recently, and it is constantly mentioned that Brian likes to drink guava juice. 
I have no memory of this ever being mentioned in the show. Is this just a product of the fannon? Was it mentioned somewhere in the show - and I just don't remember? 

I hope that someone can help me figure this out. ^____^

pretty sure its mentioned in a later ep too, when the contents of Brian's frig are being listed (offer someone a drink?)...poppers, guava juice, etc.
