I've not flown BA for nearly a year but I'm always interested to hear what's pouring in CW and F (it says a lot about an airline in my mind). I think BA F and CCR customers should be happy with the champagne offerings and the Tattinger in CW isn't too bad either.
It's also nice to hear what's route-specific as above in Lobengula's posts regarding ex-JNB.
What I'd like to hear more of is what you like about the wine (or what you don't like). Did it match well with the food and the altitude? How was the temperature? And did you like it so much you're now looking into acquiring some for your own use - if so, where from?
I'm flying F in Feb so I'll come back then with my reviews of all wines from the cabin. I look forward to hearing some of yours before then.
