Remember Guinness is a STOUT, not a beer exactly. Unless you are a fan of stouts it is doubtful you would appreciate a Guinness at first. Technically it is a beer in the fact that it is made with water, malt and hops but you will notice they don't call it a beer and neither do other stouts brewers. Also like a lot of stouts it is Charged with nitrogen, and that is what the widget is. Several good British beers, ales and stouts are nitrogen charged. Old speckled hen is one of my favorites.
Most people do not like stouts at first, but more so as they become better educated about beer and the whole brewing process, and as their palate changes. Sounds snooty but it isn't really. Beer should never be snooty. I would suggest starting out with a real black and tan. That is half bass ale and half Guinness where the Guinness is floated on the top of the Bass. Then work your way up. You could also try some Porters; they are a stout lite.
p.s. for what it is worth Guinness is a good stout but not the best. There are several much better stouts you can get. Murphy's is one I like better.
