My usual drink at the pub is gin and tonic. If I'm in a bad mood and want to get plastered, then I'm partial to a gin martini. In order of preference, my favourites are:
Blackwoods (40% premium dry one)
Bombay Sapphire
Hendricks
Millers
Saffron Gin
Juniper Green
I hate Tanqueray and Gordons.
I love cognac, and a fair amount of pubs have Remy VSOP or XO. I'm not a fan of Hennessy, but Camus is quite good.
As for whisky, I'll drink almost everything from Islay, my favourites being Laphroaig 15 year old and Bruichladdich, perhaps a good quality Kentucky bourbon such as Van Winkle or maybe a Highland whisky like Glenmorangie or Glenlivet.
If I'm not in the mood for spirits I'll drink wine, usually a red pinot noir (Napa Valley for teh win) or a white Burgundy, Pouilly Fuisse/Fume or Italian pinot grigio.
If the wines are crap then I'll be reduced to bottled beer like Tiger, Kronenberg or Cusqeuna.
And if I'm skint, a pint of Tennents will do.
