Origin of Lager Yeast

Stumbled upon this article, apparently it originally comes from Patagonia.

Just saw this as well. Pretty interesting how far it had to travel before being used for brewing.

It's really cool sounding, but I'd like to read the original article. The fact that it's been publicized before it's been published is strange. Most journals have a moratorium on that sort of thing.

I don't think it's really a yeast that flew across the ocean on a current of wind (though I could be wrong). It's more likely a common ancestor existed in Europe at one point and it's been eradicated or just not discovered yet. Kind of the same way that we're related to apes today but not direct decendents of any of those species that are around.

It wasn't publicized before being published. This is where I read about it:

It was published in the Proceedings of the National Academy of Sciences. And here's the original article:

Yeah, I've found it since. The original article didn't list the publisher and the term "ebanyus" didn't come up on either pubmed or google scholar and it still isn't indexed as of a current search. Pat McGovern (beer fermentation historian / archaeologist) shares my skepticism about travel from Peru http://cosmiclog.msnbc.msn.com/_news/20 ... -yeast-idd I'm trying to download the article as I type, but the PNAS website is getting blasted this morning. I'm not a geneticist, but I am interested to see how they argue that a yeast only found in a country that they weren't trading with at the origin of lager yeast made its way into Germany.
