Your Monday’s Thoughts On The Latest Beer News

Ah, Monday. And a Monday after a quiet weekend on the beer blogging scene hovering just at the cusp of the holiday season. Dreams of Victorian veteran carvers are starting to dance in the head.* Nothing from 1600s or 1700s brewing history is nibbling at my brain at the moment. So, I turn to that other older thing I did on the blog and give a few news items less attention than they deserve. I think something picked up as Stan’s summer intern might be to blame. Enough! Too much self examination leads to bad things like supposing one might need an editor or running off chasing another hobby. No need of that. Here’s the news.

First, Martyn has posted his findings related to a trip to Norway in search of the meaning of kveik. I initially thought this a bit odd given the voluminous obsession with the subject that has been the last few year’s work of Lars Garshol including this post from just a few weeks ago entitled “‘Kveik’ – what does it mean?” But I quickly understood what what going on – a helpful summary and transposition of sorts: kveik for dummies… like me.  Once you read Martyn’s piece, I recommend you set aside a few evenings to go back through the research results posted by Lars. The idea that a third branch of brewing yeast has been quietly living on in rural settings to the north and east of the Baltic is fascinating.

On a far smaller scale, over the weekend I tweeted a tweet:

Thoughts on a can of GK Abbot Ale. Incongruous messages about cold black tea, caramel, whisky malt, potters clay in a body with oddly flat fishy stickiness. Still… relatively cheap.

That got me thinking about how consequential each beer one pours in a glass must be. The beer in question cost $2.30 which translates to £1.38 or $ 1.80 US. If I had not been paying intentional attention, it would have passed by my mind without much comment. That weird little nod to clay would not have raised itself to my consciousness. Yet just 50 cents more would have bought me a fine example of the low end of excellent regional craft. Can we still care at all for bulk imports?

Imagine – taking money to offer a favourable opinion on a beer.  Who saw that coming?

Next up, I have one itchy thought about the whole – let’s be honest – kerfuffle going on in Portland, Oregon between a brewery and the City over the use of a leaping stag logo which has appeared on a beloved landmark sign for decades. Jeff has described the issue from the perspective of one side of the debate, which is a very important one given the small brewery actually is the party that has held the trademark since 2012. But before the trademark, there was copyright. The classes of intellectual property are distinct. The craft brewery did not create the image. The sign permit was acquired in 1940 and, as authorship immediately creates copyright, someone created the image then. So, someone must own or owned the copyright in the design of the stag which is separate from and prior to the trademark. Can one trademark someone else’s design? Apparently so – but does that extinguish the copyright? These sorts of things can vary, but if (according to Wikipedia) the sign was built and owned by Ramsey Signs from the 1940s to 2009 when the City bought the sign from them, did the underlying copyright to the sign design not also pass to the City? Dunno. I once represented a man who argued he owned 25% of Times New Roman font as he owned one of the original sets of hand made typeface. Not everyone agreed but I recall he said he did receive royalty cheques. So, who first drew the leaping stag?

I think following Ypres Castle Inn means you are of a certain age.

Finally, I do tire of references to temperance as code for everything one does not like in beer regulation. It’s up there with anxieties over lack of wine world respect. Face it – public health is a key foundation of modern western civilization. Who would chose to go back to the pre-temperence society? Even when the do gooder sociologists in their laboratories get it wrong no one in their right mind wants them stopping doing their work. Give the church its gruitgeld!!!

PS: boring big craft pretending that it’s pretty much the same as taking outside investor money and the attached strings. Somehow related.

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.

Can You Make Wild Beer In A Vineous Mono-culture?


Like most things, Canadians are about half a decade behind so it is no surprise that a group of Ontario brewers have decided to take a kick at wild beer or that some in the Canadian media reacted to the invitation as if they had no idea what was going on in the wider world of good beer. Which is nothing against those directly involved. It’s a great idea. Hope it is yummy and not sold for twenty bucks a glass. Experiment on your own dime, brewers.

Wild indigenous wine yeasts are one of the current things. Like Citra hops. Craze that might be a fad. Here today and gone tomorrow. Yet the yeast is itself. From the photo up top from the Macleans magazine article, you can see the brewing is done in a vineyard, an agricultural monoculture. But is it a monoculture of yeast even if the plants are all clones? Apparently not. We learn that our mutual friend Saccharomyces cerevisiae is certainly on the grapes but only on about 1 in 1,000 berries. What else is in there? The beer will tell. Could be tasty. Hopefully.

PS: get a coolship, wouldja? Wild inoculation via narrow topped vessels might be less than optimum if the history of beer before a hundred or so years ago is anything to go by.

So – When Was Lager Invented… Discovered… Evolved?

This is either just a bit weird or I have completely missed something. Apparently some scientists have been looking to find the yeast strain that started lager… and they think they have found it:

When the team brought the yeast to a lab at the University of Colorado and analyzed its genome, they discovered that it was 99.5% identical to the non-ale portion of the S. pastorianus genome, suggesting it was indeed lager yeast’s long-lost ancestor. “The DNA evidence is strong,” said Gavin Sherlock, a geneticist at Stanford University who has studied lager yeast but was not involved in this study. But Sherlock wondered how S. eubayanus could have traveled the nearly 8,000 miles from Argentina to Germany. “We all know that in 1492, Columbus sailed the ocean blue,” he said. “Lager was invented in the 1400s. It’s not really clear how that progenitor would have gotten from South America to Europe.”

Whazzates’sayin’?!?! Look, don’t get me wrong – yeast is interesting stuff. But to say lager was “invented” in the 1400? Now, if I dip into my copy of Hornsey, I don’t run into lager until the 1800s at page 485. Yet this story I posted in 2008 speaks of lager yeast evolving in the 16th century in a Bavarian cave which gets us in the ball park in terms of centuries. Maybe it’s the use of the word “invented” in the article that threw me off.

Most interesting of all, Gavin Sherlock posted a comment at this here blog back in 2008 as did Drs Dunn and Sussman all involved in this project. I will stay well away from the term “egg head” this time and invite some direction on their work and the implications for the lagered time line.

Yuck! That Yeast Is Flocculating Itself Again!!!


When I was a home brewer – as opposed to a person who has home brewing supplies and equipment in the house but never does anything with it all – I used to be concerned about flocculation. Flocculation is the word that describes the capacity of a yeast (or other stuff for all I know) to clump. It is a fancy pants word for clumpiness – but is more about the propensity to clump as opposed to the clump itself. I think. If a yeast strain floucculated too much it could cause precipitation leading to poor attenuation due to separation of yeast and wort. Yet if the yeast was under flocculating there would be difficulty in settling out and creating a bright beer. I think.

So, it is comforting to know that all my half baked understanding of yeast clump-a-bility is actually related to a massively important scientific moment:

A team of scientists at Harvard University reported last week that they isolated the single gene that allows yeast to stick together. That gene allows the normally solitary yeast cells to shield themselves from toxins in their environment by banding together in protective balls. Since one of those toxins is the ethanol that the yeast themselves produce, grouping together allows the yeast to survive in the alcohol-rich environment that results from brewing. What’s more, the gene has a built in social value system that prevents yeast cells without the gene from taking advantage of the yeast flock’s protective sphere. That social control mechanism is an example of how single cells can regulate function in larger units.

Excellent! I knew that something about beer was out there promoting social values…or is it promoting socialism!?!?¹

The point? As Kevin Verstrepen, one of the eggheads in white lab coats² – a Haavaad man no less – notes: “You can look at it as a model of how single-cellular organisms can cooperate, taking a small step toward multicellular life.” A-ha! No, not the Norwegian 80’s band…I mean “a-ha” as in light-klicky-on, as in “EUREKA!!!” So not only was the creation of civilization dependent on beer but the core zymurgystic fact of beer is also the same core fact of complex life as we know it. See? Without the making of alcohol, we are all single cell amoeba… amoebae… amoebas. I think. Which leads me to my amoeba joke: “two amoeba leave a bar and look up at a bright light. One says to the other ‘is that the sun or the moon?’ to which the other replies ‘I dunno. I don’t live around here.'” Get it? That is what we would have to put up with were it not for the flocculating powers of yeast. And nobody wants that.

¹Cue the theremin music!
²…and let’s not have a repeat of the whole “sensitive yeast scientist” thing this time, ok?

More Yeasty History, More Yeasty Science

It seems like just a couple of weeks ago that I was learning about yeast history through science. Oh. It was just a couple of weeks ago. Now, instead of reaching back just four centuries, science is taking us back through over 400,000 centuries of yeastiness:


Why is it, even though there are 38,000 results for the Google search “Raul Cano beer“, that I have never heard of this? Look – it even has a website. You never tell me anything. More about the back story here but the interesting thing is not that it is done so much as it is not done more. Think about this. If dormant yeast can sit in the belly of a bug enclosed in amber, it must be lots of other places. I recall seeing some history show about medieval life in which the historian in charge of some European farming community site explained how, when they wondered about how they could figure out what food grains had grown there, they realized it was all around them in the deepest layers of the thatched roofs.

Hornsey describes how pot shards from pre-historic digs are studied for chemical residues to confirm their use in brewing. So, what is like a thatched roof and like amber that could hide a yeast that just happened to be used in the porter breweries of 1700s London or a dark ages monastery? Where can dormant yeast hide? Can it be sitting in a deeply buried layer of turf hibernating next to the old brewery wall or in a dried up goo residue that long ago seeped its way into the cracks in the beams of a 1400s ale house? Can it be identified that closely? And what do you call that search – is it yeast forensics? Or is it more like microbial archaeology? Is someone out there doing this right now? Are you holding back about that, too?

Two Lager Yeast Strains, Two Homecaves

I am sure I will get this wrong and that Ron will be able to clarify but it appears that two forensic yeast researchers have determined that lager yeast came into existence twice during two separate events:

…the team discovered that it happened at least twice in two separate locations in Europe, giving rise to the two different lager families…The hybrid, which makes lager instead of ale, probably evolved in Bavarian beer-brewing cellars during the 16th century. The team also found that Saaz yeasts have a single copy of each parent yeast’s genome, whereas the Frohberg yeasts have an extra copy from S. cerevisiae. They believe this difference affects the flavour of the lager, as well as how quickly the yeasts can ferment the hops.

OK, so the egg heads in lab coats don’t know that hops do not do the fermenting. Forgive them. Take a breath. There, that’s better. Apparently, that there are Saaz and Frohberg strains of lager yeast has been long known. But what was not known was that they developed independently from each other – as this article in today’s New Scientist explains in further detail. Sadly, they cannot trace back to which Bavarian cave gave birth to which strain and when. Even more detail here including this interesting tidbit:

Studying the spread of the two groups provides a genetic snapshot of lager brewing in Europe during the past 600 years: one lineage is associated primarily with Carlsberg breweries in Denmark and others in what is now Czechoslovakia, while the other group localizes to breweries in the Netherlands, including Heineken.

Neato. The team’s full research results will be published tomorrow by Genome Research.
