Yeast News: Migrating Birds And Sheboygan

One of my slowest moving interests in beer comes in the form of a trickle of stories about the origins of lager yeast. In 2008, there was the tale of the two Bavarian caves. Then there was the dinosaur era yeast story. Then in 2011, the ur-yeast for lager was found in Argentina. Now, it turns out that little bit of goodness shows up elsewhere, too:

It is the first time the microbe has been found in nature in North America, or indeed outside of Patagonia. Found by UW-Madison undergraduate student Kayla Sylvester, a member of Hittinger’s group, the yeast occurs only at a very low frequency and was likely accidentally introduced, just as an ancestor found its way to Europe and kick-started the production of cold-brewed lager beer hundreds of years ago. “If I had to bet, I’d lay money on ski bums or migrating birds” as the agents responsible for transporting the microbe to Wisconsin, says Hittinger. “What we think is happening is that well-established, genetically diverse populations are sending migrants around the world. Generally, they’re not successful, but occasionally they are.”

I love this stuff. One of my proudest moments was when the yeasty eggheads jumped in the conversation and gave me more details in the comments. I even got corrected and edjificated that the proper written form is “egg head.” The goal of all this is “to tap into biodiversity and find the strains that ferment better” according to study lead UW-Madison Professor of Genetics Chris Hittinger. Which beats the hell out of making synthetic yeasts to get more of that candy store mango taste into out future beer.

As Boak and Bailey noted today, there is an end to the pursuit of the merely novel, the manufactured. The law of diminishing returns demands no less. But the exploration of the actual, the natural and traditional? I’ll buy that, too.

Ontario: It’s Beer Book Page Proof Reading Time

obbpage21Even though I have been writing about beer for over a decade, I have not had the pleasure of the page proof experience before. It balances between sheer terror and giddy delight as I see that so much of what I hoped for the book Jordan and I have been working on since last summer has come into being – while at the same time I am still correcting myself on a few last tiny things. Oh. Me. Nerves.

The best stuff frankly relates to things beyond my doing. That is the top of page 21 over there. Jordan selected the photo and wrote the caption. The good folk at History Press chose the font and prepared the layout. And, as noted, even a major concept at that point of the story was provided by sometimes comment maker around here Steve Gates. The bibliography sets out a selection of the sources relied upon but it still runs for three and a half pages. I just wrote the text at that bit. I wrote it before Christmas. Rereading your own work at page proof time confirms the adage that the past is a foreign land.

I like the cover, too. Didn’t know I would. Someone else took care of it. It’s odd. There are so many people involved. I had no idea. Blog writing is so private by comparison.
