As I mentioned Monday, Andreas Krennmair has posted a recipe for a turn-of-the-century steam beer, warning readers, “This recipe does not conform to the BJCP Style Guidelines for the California Common beer style, so don’t use this to brew beer and get bad marks for it at home-brewing competitions.”

How similar would it have tasted to a steam beer in the 1890s or one shortly after the beginning of the 20th century?

First off, we don’t have much in the way of tasting notes. There was his from July of 1896, by a journalist assigned to write about being “A Prince for a Day in San Francisco on Two Bits” in The San Francisco Call. He put a glass of steam beer, which along with a choice of dishes and bread cost a nickel, at the center of his first meal.

“Upon the surface of amber-colored beer floated foam as evanescent and light as thistle down,” he wrote, without naming the brewery where it was made. “The receptacle holding the beer was as deep and as musical, as it was clinked against another, as a bell of Shandon ‘That sound so grand on the River Lee.’ Clearly through its translucent sides could be observed sparkling effervescence, the riotous ascent of sparkling globules which conferred, as a reward for patronage of a plebian beverage, a delightful tang, in which was all the lusty flavor of sun-kissed fields of bearded barley, waving and rustling in the wind.”

Second, every ingredient is a wild card, but yeast is the wildest of all. Presumably, yeast used to brew steam beer evolved from a lager strain. However, in 1911, while conducting tests as part of another project at the University of California, T. Brailsford Robinson discovered just how different steam beer yeast acquired from California Brewing in San Francisco was from lager strains.

“The yeast of the steam beer has accommodated itself to these conditions (warmer fermentation and the clarifier) to such an extent that it can no longer be employed for the preparation of lager beer, while lager-beer yeast may without difficulty be used for the manufacture of steam beer,” he wrote. “The cells of the typical steam-beer yeast are somewhat smaller than those of lager-beer yeast.”

Because things happen, like Prohibition, the strains that brewers used then were not passed down.

Fun aside

Over the years, there have been several suggestions about why steam beer was called by that name:

– What looked, and sounded, like steam was generated by the pressure generated in the kegs.

– Steam hung above rooftop vessels that initially cooled the beer.

– “Doctor Steam” (whose first name has been given variously as Frank, Heintz, or Charles) invented the process.

– German brewers would have been familiar with Dampfbier (“steam beer” in German), itself a hybrid.

– The first brewer to make it, according to his son, named it “mission steam beer, after the (California) missions.” (f

[Begin disclosure] I once owned the domain name beerterroir.com. Like a dozen other urls I paid rent on it a few years before I let it disappear into a distant corner of the internet. It’s available, should you want to claim it.

I registered it in 2006, only hours after Sam Calagione made fun of the word terroir in his Craft Brewers Conference keynote. (More on that in a moment.) But I wasn’t inclined to use the word as it relates to beer in a sentence. I understood it was (and is) considered a “wine word” and even so writer Jamie Goode described the concept in wine as “blindingly obvious and hotly controversial.”

I became more comfortable with the word as I researched “For the Love of Hops” and continued with “Brewing Local,” although I continue to prefer “taste of place.”

Amy Trubek concludes “The Taste of Place: A Cultural Journey Into Terroir,” an absolutely terrific book, by writing “ . . . the taste of place exists, as long as it matters.” To repeat myself, I’m more inclined to use the words taste of place opposed to terroir, but I’m fine with “beer terroir exists, as long as it matters.” Both matter to me.

Friday I moderated a panel discussion about these and other related topics held in a barn on Wheatland Spring Farm + Brewery in Virginia along with a winemaker/grape grower, a cidermaker, a James Beard award winning chef, and a brewer/farmer. I am invested, and that bias informs how I think about terroir. [end disclosure]

Which brings us to Monday morning. Right after I posted TWTBWTW I opened my feed reader and saw the headline, “There is No Such Thing as Terroir in Beer.” I looked at the list of things I intended to have done by the end of the day and thought, “No time for this.” Remember, though, I’m invested. I wanted people to read the story, because I am happy when they give terroir or taste of place some thought, even when I don’t agree.

That’s why I posted a link on Twitter. I already knew I was going to write something like this when I had time, but I included the briefest summary possible of what I thought of the headline: “Wrong.” I guess Matt Curtis, who wrote the story, was offended. He called this a “tad unprofessional.” Perhaps I should have typed, “Disagree.” Anyway, he also asked “Why?”

So here goes. Bullet points, because otherwise . . . The first chapter of “Brewing Local” is about “beer from a place” and runs about 8,000 words. And a recent Hop Queries contained more than 2,500 words on hop terroir itself.

– “Grand dictionnaire universel du XIXe siècle,” Pierre Larousse’s nineteenth century French dictionary, defines terroir as “the earth considered from the point of view of agriculture.” It describes le goût de terroir as “the flavor or odor of certain locales that are given to its products, particularly with wine.”

– Trubek prefers what she calls the “French foodview,” arguing that in France the narrow scientific and broad cultural definitions of terroir are often used simultaneously. “This broader definition of terroir considers place as much as earth. According to this definition, the people involved in making wine, the winemaking tradition of a region, and the local philosophy of flavor are all part of terroir,” she wrote. “Unlike the narrow view of terroir, this humanist point of view is not really quantifiable. Terroir speaks of nature and nature’s influence on flavor and quality, but here the human attributes we bring to ‘nature’ are cultural and sensual rather than objective and scientific.”

– There is real science behind terroir, although that doesn’t have to limit how we think about it. Here’s an example I use all the time, from geneticist John Henning at the United States Department of Agriculture research facility in Oregon. Environment and epigenetics combine to make hops from a particular area unique. All plant species have methylated DNA, which causes some genes to be “switched on” more easily than others.

Differences in soil, day length, temperatures, amount of rainfall, and terrain all may influence the methylation process. The underlying DNA does not change, but the methylation pattern can be different, resulting in differing concentrations of the chemical compounds produced by the plant.

– At Freestyle Hops in New Zealand, they draw a distinction between this science of terroir and what they call “terroir expression.” It mirrors Trubek’s French foodview. The expression is a combination of the environmental factors, cultural practices, the operating processes and the individual people at the farm who create the flavor of their hops. CEO Dave Dunbar says, basically, that New Zealand has a unique terroir (blame a nearby hole in the ozone if you want) for hops, a good thing, and that Freestyle seeks to build on that, to create a better thing.

– As promised, from Calagione’s 2006 keynote: “If you can’t blind them with science, blind them with geography. Je parl francais en peu, and I’m pretty sure the translated definition of terroir is ‘dirt’. The wine world has wrapped this one word with mighty voodoo powers and created a cult of exclusivity around it. Breweries have terroir as well. But instead of revolving around a patch of land, ours are centered on a group of people.”

– In the penultimate paragraph (you know, the one in which Wallace or Stringer Bell dies) of “No Such Thing” Curtis writes, “I accept that you could produce a beer using ingredients grown on a single farm, brewed with the same untreated well water that was also used to irrigate the hops and barley used in its production, and fermented only with the yeast airborne above those same fields. You could even take this a step further and not boil it, creating a ‘raw’ beer, further removing the human element that takes the nature of a beer away from the land on which it was born. I believe there is a future for a small amount of beer to be produced in this way, even if this method is as challenging as it is commercially unviable. Yes, you can connect beer to its agriculture and its seasonality, but this is not the same as its flavour being a direct expression ‘of the earth’.”

– That seems like a limited view to me, based on a narrow definition. In my view, beer does not reflect its terroir by accident. Brewers matter. Different beers at Wheatland Spring taste of the 30 acres the farm sits on in different ways. They are all brewed with the same intention, to connect the land and the beer.

They are made with the same well water. Some are fermented with wild yeast collected on the property. Some are brewed only with estate grains, some include grains from nearby. There will be more. Saturday, Nicholas Santantonio, the breeder at Virginia Tech, grabbed spikes off experimental plants Wheatland Spring is trialing and talked about their most important attributes. They are better suited to grow in the region and they deliver unique, desirable flavors.

– I have, somewhat by chance, tasted batches 1, 2 and 4 of Wheatland Spring Estate Return, brewed with estate barley. They taste of the same, but not exactly the same as each other. Also not quite like any other beer. Trubek once shared an office at the New England Culinary Institute with Mark Davis, a teacher and trained wine sommelier. He told her, “Terroir is character. It is the triumph of diversity over homogeneity.”

Saturday, I saw the genesis of more of that in the test plots at Wheatland Spring.

“No Such Thing” concludes, “Although, I still believe in the potential for beer to truly express a sense of place, but maybe that place isn’t a field, or an orchard, or a hillside. Maybe, that place is one with dark wooden furniture, and a deeply worn, patterned carpet. One soundtracked by the hum of gentle chatter, and a friendly face behind the bar that asks the question ‘same again?’ If beer is expressive of anything, then this expression is found, not where it is grown or made, but where it is served, and this, surely, is what makes it so special.”

This expansive view of terroir or taste of place mirrors one put forth in “Beer Places: The Microgeographies of Craft Beer.” The book is a collection of essays, mostly by academics, and contains phrases like “banal authenticity” and “spatial politics” that are at least as hard as terroir to wrap your head around.

The authors of the introduction write, “The taste of place refers to the unique flavors and experience of each beer, and how these embody the webs of ingredients, social networks, and layers of place that converge on the production and consumption of craft beer.”

“Webs of ingredients” does not seem to acknowledge the role agriculture plays in taste of place as much as I’d like. But that’s not something I intend to take up on Twitter. The fiery conversations that “No Such Thing” ignited are still burning bright and I have no interest in participating.

Imagine hiking in the mountains of wherever, emerging from a stand of trees and seeing a half dozen pools on the flat rock surface ahead. And that the smell that filled the air was just like your favorite beer.

Yet when you sidle up to them individually, getting close enough to sort out what each of them contributed on their own it is obvious they are unique.

Might you call them beer aroma pools?

Randy Mosher introduces this idea—that is aroma pools, sans the mountains—in the current (Spring 2023) issue of Craft Beer & Brewing. The inspiration comes from a research article with the roll-off-your-tongue title of “A New Classification of Perceptual Interactions between Odorants to Interpret Complex Aroma Systems. Application to Wine Aroma.” You may download it here, but I recommend skipping directly to Mosher’s beer version.

Let’s start with the odor activity value (OAV), which you might recall is discussed in “For the Love of Hops.” The OVA equals one when the threshold of detection of a compound is equal to the quantity present.

In the wine study, researchers blended single chemical compounds to create a model wine aroma. They then began removing them to determine which ones really matter. The model included 14 ethyl esters, only six of which had an OAV greater than 1. They were able to remove every ester except one and still maintain the same fruity character as long as they increased the quantity to match the original intensity.

Mosher writes, “As a group, the esters were so resilient that scientists termed them a ‘buffer.’ Even though many of the original esters were far below threshold values, they were strongly interacting—demonstrating superadditivity, a kind of synergy.”

He asks, “Is beer odor structured similarly?” The answer is yes, and he makes the case. So I suggest you track down a copy of the magazine. As you might expect, Mosher has also created lovely diagrams of how to think about both wine aroma pools and beer aroma pools.

A bit of a disclosure. I occasionally write (and thus am paid by) Craft Beer & Brewing. I write about hops regularly for Brewing Industry Guide, which is produced by CB&B.

It is early in the year, but this bar mat from Sawmill Brewery will be tough to beat in the annual “best bar mat I’ve seen this year” contest I hold in my head. As seen at The Brewers Co-operative in Auckland. I want a place like the co-op within walking distance of our house in Colorado.

“These are my moisture meter,” said Brent McGlashen, a fifth generation hop grower, well into a day last week punctuated with frequent grabbing, breaking and smelling of freshly picked hops being kilned on one of the Mac Hops farms.
