Speaking of beer, and I write this from memory, in the original The Book Of Lists
By David Wallechinsky & Amy Wallace, they conducted a beer tasting survey in order to determine the best beer in the world.

Now, before I go any further, I say again I write this from memory, and I may have wrongly attributed the following survey.
Nonetheless, someone credible did it if not David Wallechinsky and Amy Wallace.

So, they conducted this beer survey in Washington D.C. because they thought it would give them access to the most internationally diverse of beer drinkers.
They divided the beers into two groups: dark and lager.
They thought the two different enough that it would invalidate the survey to compare them head to head.

They set up a tent on, I think, the Mall in front of the White House, between the Washington Monument and Lincoln Memorial.
They served free beer for several days.
In order to get a free beer, a person had to actually take two beers and compare them.
David and Amy only wanted to know which of the two uindentified beers the drinker preferred.
Heineken won the best dark beer award and, surprise of surprises, the cheapest beer sold in America won the lager award - Old Milwaukee.

Incidentally, Old Milwaukee won again, last year; this time for Best American-Style Lager, at the Great American Beer Festival, held every October in Denver, CO.

I don't drink any longer.
I have a problem with alcohol, and so I haven't had a drink in 22 years.
But when I did drink, I kept Old Milwaukee in business.

I have a lot curiosity about the microbrews.
Maybe after I retire, if I ever do, I'll give them a try.
