Guinness: big, smooth, bold, smooth, yummy, and it goes down smooooth. My fave! It's like drinking slightly carbonated, beer flavored chocolate.
From the tap
Guinness from the bottle is ... OK. It can't touch Guinness from the tap, especially from an Irish bar with lots of old, chipped wood tables, with your rowdy friends all around and maybe some Irish punk music playing in the background.
Here is a cup of extra strong coffee with 3 teaspoons of brown sugar to add thickness... notice the resemblance?
