John Constantine is depicted as drinking nearly all the time. Constantine declares himself "Whiskey King" in the Swamp Thing "The New 52" series, volume 5, issue 22.
Constantine's favorite whiskey, however, is something of a mystery.
In the 2005 Constantine film adaptation, Detective Angela Dodson (Rachel Weisz) visits Constantine asking for help with the apparent suicide of her sister Isabel (also played Rachel Weisz). In this scene, Constantine is drinking Ardbeg 10.
In the Constantine TV series, the Matt Ryan version of Constantine is drinking a fictitious brand of whiskey (pictured below). The whiskey's name appears to be a “mash” up of two different real whiskeys: Glenlivet and Glen Elgin. Glenlivet is one of the more recognizable brands of Scottish whisky. Glen Elgin is a distillery in Speyside, Scotland.
This kind of whiskey name mash-up, like MacCutcheon and Macallan in Lost, is pretty common. According to one report from a prop master, it’s because the distilleries don’t want their brands “watered-down” by product placement. Whisky is not New Coke.
