Excluding the obscure & unique micro-brewery beers (Ales and Lagers)
Kilkenny is the only beer for me.
It is a very creamy and smooth Irish cream (red) ale that's a 4.3% alc/vol.
Like Guinness, it contains a nitrogen 'widget' that gives it the perfect head each time you pour one. But, unlike Guiness, it does not taste like sewer (soy/soya) sauce. It is a real treat and all the people I have introduced it to have cursed me for getting them hooked!
It must be extremely cold, as well I suggest pouring it in to a frosted mug.
