I don't compare it to coffee either Steve. I like Guinness and I like most of the "real ales" I quaff. I don't see it as an either / or contest.
Travelling a lot used to mean at least with Guinness you knew what you were getting. Also, concerning beer in the house, cans of draft Guinness are most like the tap version of all beers for me whilst bottles of most of the real ale types tend to be a bit gassy. Doombar being one of the worst culprits (though of course such bottles never saw Cornwall.)
So... Which is the best beer for Liverpool fans to cry into at 4.50pm on a Saturday then? 😎
