To coincide with St Patrick's Day an article in the Economist has debunked the usual Guinness guff, and even claims that in the 80s it came close to being re-branded as an English stout.
There's some interesting stuff in the article. I knew the Guinness family are prods, and were opposed Irish independence, but I was surprised to see that one went as far as providing considerable funding to the original Ulster Volunteer Force in 1913. I haven't studied the history of Guinness, and sadly no references were given, but I'm temped to start now. Though perhaps I'd better get through all the beer books and magazines I have piled up around me first.
