I still need to go to the US one day and go see for myself if these ridiculous cliches are actually true. I've heard you guys don't actually like beer, you just like to pee a lot 

We had some exchange students in our family for some months on a few separate occasions. I asked one group what was the most surprising thing about America and his reply was "yellow school buses." He said that growing up he heard crazy stories over and over that school buses in America were all yellow. He got here and found it was mostly true. He thought it was hilarious.

I don't know much about the history of beer except that it is ancient food. As for America's beer history, I have no idea how it ended up that this country spent so many years stuck with 2 main watered down beers (Budweiser, Miller) for so long. Of course there were other semi-popular regionals, then Coors became #3 for a while. Bud, Miller, Coors. Bud Miller, Coors. Occasionally some Pabst, National Bohemian, Milwaukee's Best.
I worked at a liquor store for a chunk of years as a young fella. We were "the" liquor store in our area because we had a large selection. It was considered pretty mind-boggling that we carried 20 different beers. Now, of course, there are 20 different beers on one shelf in that store, and many shelves.
I recall around the late 80's we started getting a few micro-brews ("craft beers") as that niche was taking off here. Pete's Wicked Ale became my favorite until @1998 when they were bought and the flavour changed. But during those years there was an explosion, and now we have many. I love trying different beers but I usually go with a stout when I have a chance, and go for Guinness when it is on tap. I have a bottle of 1987 Hardy's Ale in the kitchen waiting for something to celebrate.
