Angus, if you don't like to drink Guinness, you can cook with it!
Within reason - I remember (just) at a really early drag race meeting at Santa Pod (c.1976) my mate trying to cook burgers for breakfast and had forgotten the cooking fat (pause for Carry On aficionados to giggle) so he used stout - probably Newcastle Brown, maybe Guinness - whatever it was brown. Inedible. QED.
I suppose you could slow cook beef with it but I'd still rather play safe with a good London Stout...
No beef really, just pointing out the analogy does not work for everybody - a bit like Windows 8 really.

OK, two things are wrong there.
1. Minced meat, therefore burgers, contain a certain amount of fat; you don't need to add any extra fat to cook them, unless you have some kind of meat that is extra lean and has then had water added to increase its weight. The moral of this is to always make your own burger patties from meat that you have bought from a butcher you trust.
2. Dog (i.e., Newcastle Brown Ale) is certainly neither stout nor porter. It's sweeter, less bitter, far lower proportion of burned malts, no coffee-bean flavour.
