I was never a beer drinker growing up, mainly because my dad drinks the cheapest, palest crap he can get, so naturally I thought all beer tasted like watery piss. Then I started getting exposed to richer beers later on and finally Guinness, which is not my favorite beer (though very near the top!) but is an excellent "go to" beer and is widely available, plus has a pretty unique appearance that typically shames the miller lite drinkers around you.

FWIW, having a shamrock or heart in the head means the pint was poured correctly. You are supposed to fill the pint glass about 3/4ths full, then allow it a minute or so to settle, then pull the tap in reverse for a slow finishing pour that allows you to make the design in the existing head. This extra time shows a bartender who respects the brew.

My favorite beer is "Old Engine Oil". So thick and tarry it does resemble burned oil to an amazing degree. I also am a huge fan of "Ola Dubh" which is a porter finished in Highland Park scotch barrels. If you go to the right place and are willing to pay you can even get a dram of the Highland Park from that same barrel to go with the beer!
