Beer and Geology, from the New York Times.
I noticed this in the New York Times yesterday: With Great Beer, It's All in the Rocks (and That Doesn't Mean Ice) by Kenneth Chang. (registration required)
And as Dr. Maltman got up to talk, two-thirds of the audience also got up and headed for the lobby, where Denver microbreweries were handing out samples in small cups.
"I'd like to suggest this evening, to the people who remain, that in fact it is with beer that there is the most direct link between the drink and geology," Dr. Maltman said.
I stayed for his talk, and it was quite interesting. Then I went for the beer. The article is a much better description of the talk than was my earlier post. Cheers!
