Today is the birthday of Anders Jöns Ångström (August 13, 1814–June 21, 1874). He “was a Swedish physicist and one of the founders of the science of spectroscopy.” The Ångström unit (1 Å = 10−10 m) in which the wavelengths of light and interatomic spacings in condensed matter are sometimes measured are named after him. Various types of spectroscopy are employed in the brewing industry.

Anders-Angstrom

Here’s a partial biography of Ångström from Wikipedia:

Anders Jonas Ångström was born in Medelpad to Johan Ångström, and schooled in Härnösand. He moved to Uppsala in 1833 and was educated at Uppsala University, where in 1839 he became docent in physics. In 1842 he went to the Stockholm Observatory to gain experience in practical astronomical work, and the following year he was appointed keeper of the Uppsala Astronomical Observatory.
Intrigued by terrestrial magnetism he recorded observations of fluctuations in magnetic intensity in various parts of Sweden, and was charged by the Stockholm Academy of Sciences with the task, not completed until shortly before his death, of working out the magnetic data obtained by HSwMS Eugenie on her voyage around the world in 1851 to 1853.
In 1858, he succeeded Adolph Ferdinand Svanberg in the chair of physics at Uppsala. His most important work was concerned with heat conduction and spectroscopy. In his optical researches, Optiska Undersökningar, presented to the Royal Swedish Academy of Sciences in 1853, he not only pointed out that the electric spark yields two superposed spectra, one from the metal of the electrode and the other from the gas in which it passes, but deduced from Leonhard Euler’s theory of resonance that an incandescent gas emits luminous rays of the same refrangibility as those it can absorb. This statement, as Sir Edward Sabine remarked when awarding him the Rumford medal of the Royal Society in 1872, contains a fundamental principle of spectrum analysis, and though overlooked for a number of years it entitles him to rank as one of the founders of spectroscopy.

This is the general definition of spectroscopy from Wikipedia:

Spectroscopy is the study of the interaction between matter and electromagnetic radiation. Historically, spectroscopy originated through the study of visible light dispersed according to its wavelength, by a prism. Later the concept was expanded greatly to include any interaction with radiative energy as a function of its wavelength or frequency. Spectroscopic data are often represented by an emission spectrum, a plot of the response of interest as a function of wavelength or frequency.

This abstract from the 2006 paper “Applications of Vibrational Spectroscopy in Brewing” gives an overview of their use by brewers.

The purpose of this chapter is to compile the literature concerning the applications of near‐infrared (NIR), mid‐infrared and Raman spectroscopy in the brewing industry. All these three techniques share the advantages that they are rapid, can be noninvasive and allow direct observation of specific molecular species. As for barley, many researchers have used the NIR reflectance on whole grains in malt evaluation. The NIR determination of α/β‐acids and hop storage index in baled hop samples is reported. NIR spectrophotometric methods have been developed for the determination of yeast concentration and activity in beer making. In addition to the applications in the laboratory of quality control, the overview concerns also the applications of infrared and Raman spectroscopy in monitoring of operation and process control at the essential steps of mashing and wort fermentation in brewery. The results obtained with a short wave NIR spectrophotometer are presented in comparison with long wave NIR spectrophotometers.

Brewers use spectrometers to measure a number of QC items throughout the brewing process.

Historic Beer Birthday: Max Schwarz

July 29, 2024 By Jay Brooks

american-brewer-old
Today is the birthday of Max Schwarz (July 29, 1863-February 7, 1901). He was the son of Anton Schwarz, who owned the magazine/journal American Brewer, which he turned into a serious scientific journal, writing many of the articles himself, and is credited with helping the entire industry improve its standards and processes. His son Max took over as publisher of the American Brewer when he passed away.

Max-Schwarz

He was also mentioned in his father’s entry in the Jewish Encyclopedia, published in 1906.

Schwarz’s eldest son, Max Schwarz (b. in Budapest July 29, 1863; d. in New York city Feb. 7, 1901), succeeded him as editor of “The American Brewer” and principal of the Brewers’ Academy. He studied at the universities of Erlangen and Breslau and at the Polytechnic High School at Dresden. In 1880 he followed his father to the United States and became associated with him in many of his undertakings.
Both as editor and as principal of the academy he was very successful. Many of the essays in “The American Brewer,” especially those on chemistry, were written by him. He was a great advocate of the “pure beer” question in America.

And here’s his obituary from the American Brewers Review, Vol. XIV:

Moon Crater “Beer”

May 16, 2018 By Jay Brooks

So this is an interesting bit of ephemera. There’s a crater on the Moon that is named “Beer.” I’d like to think it was named for the beverage, but unfortnately that’s apparently not the case. That would have made for a better story, but c’est la vie. Instead, there was a German amateur astronomer who it was named for. The crater in the center is one the called “Beer.” The other big one, in the upper left, used to be called “Beer A” but is now known as Feuillée. The string of smaller craters (known as “craterlets”) in a line to the east-southeast of “Beer” used to be called “Fossa Archimedes” but it’s been suggested they should be called “Catena Beer,” and it seems to be catching on.

Here’s how the name came about:

Named for Wilhelm Wolff Beer (January 4, 1777 – March 27, 1850), a banker and astronomer in Berlin, Germany. Beer built a private observatory with a 9.5 cm refractor in Tiergarten, Berlin. Together with Johann Heinrich Mädler he produced the first exact map of the Moon (entitled Mappa Selenographica) in 1834-1836, and in 1837 published a description of the Moon (Der Mond nach seinen kosmischen und individuellen Verhältnissen). Both remained the best descriptions of the Moon for many decades.
Beer was Catalog Number 1185 in the original IAU nomenclature of Named Lunar Formations. The designation is attributed to Birt, and had earlier been adopted by Neison, 1876 (where the designation Beer A is used for what is now known as Feuillée, differing from the modern usage of Beer A for the much smaller crater selected in Named Lunar Formations). Schmidt is said there to have called this feature Hamilton (unrelated to the modern Hamilton) and to have used the name Beer for the crater now known as Rosse. However, Schmidt himself says that his personal preference since 1856, based on the Lohrmann maps (which he edited), was to call the present crater pair Beer and Mädler, but he changed these to Hamilton and Feuillée in his 1878 book in an effort to be consistent with the English observers.
In his 1880 article, Neison equates Schmidt’s 1878 Hamilton and Feuillée to his 1876 Beer and Beer A and the British Association’s Beer and Mädler.

The Planetary Society has an interesting post where they show an experiment of taking photos of the moon “under different solar illumination conditions.” The NASA photos are all of the craters Beer, Feuillée and the craterlets Fossa Archimedes, which are also known as “Catena Beer.”

Chalybeate Beer

February 20, 2018 By Jay Brooks

Today is the birthday of Henry James Pye, who “was an English poet, and Poet Laureate from 1790 until his death” in 1813. In one of his works, entitled “The sportsman’s dictionary: or, The gentleman’s companion: for town and country.” and his version was based on an earlier anthology work which he “Improved and Enlarged” and published in 1807. Under the entry for “Glanders” — an infectious disease primarily in horses — something was prescribed called “Chalybeate Beer” that included directions for how to make it. From what I can tell, “Chalybeate waters, also known as ferruginous waters, are mineral spring waters containing salts of iron.” They were apparently thought to be good for you and “in the 17th century, chalybeate water was said to have health-giving properties and many people have promoted its qualities.” Water from the springs was bottles and sold as medicine. Chalybeate springs were located throughout Europe, though especially in England, Scotland Wales, and there were at least seventeen prominent springs in the United States.

A chalybeate spring, identifiable because of how the iron turns the color of the water.

Here’s the passage about how to make Chalybeate beer (followed by the original):

A Chalybeate Beer, may be made as follows: Steel filings, sixteen ounces; cinnamon and mace, each two ounces; gentian-root bruised, four ounces, anniseeds bruised, three ounces. Infuse in one gallon, fine, clear, old, strong beer for a month, stopped close, shaking often, then strain. Give half a pint for s dose, in a pint of cold water, once or twice a day, upon an empty stomach, leaving the horse an hour or two to his repose. I have taken this from the Vinum Chalybeatum of Boerhaave, substituting old beer, which I have reason to believe a good menstruum for the steel, instead of Rhenish wine; and adding one of the best bitters. Should cinnamon and mace be thought too expensive, Jamaica pepper, or allspice, would be a cheap and proper substitute. It was the opinion of that great man, that no drug, diet, or regimen, could equal the preparations of iron, for promoting that power in the animal body by which blood is made; of course, it must be a powerful specific, in all cases of over-relaxed solids, debilitation and consumption. Would not chalybeate beer be a cheap and efficacious medicine for the poor?

Now doesn’t that sound tasty?

Beer In Ads #2486: Alice Studies Natural History

December 10, 2017 By Jay Brooks

Sunday’s ad is for Guinness, from 1952. While the best known Guinness ads were undoubtedly the ones created by John Gilroy, Guinness had other creative ads throughout the same period and afterward, too, which are often overlooked. This ad, one of many that used Lewis Carroll’s Alice in Wonderland is titled “Alice Studies Natural History,” and features a Carroll-esque story about a tiny Alice conversing with the red queen about science … and Guinness.

Coza Powder, The Cure For Drunkenness

June 8, 2017 By Jay Brooks

The 19th and early 20th century is filled with accounts of quacks and patent medicines sold by snake oil salesman. All sorts of wild claims were made and almost without exception they were complete bunkum. I just came upon one I hadn’t seen before, something called Coza Powder, from the Coza Institute in London, England. Here’s the ad, from “The Strand Magazine,” published in 1907. I also found examples of the same ad as late as 1909, and even a couple in Spanish, so it appears to have been sold worldwide.

There’s a lot not to like about Coza Powder, but it’s an amazing ad. First, there’s that horrific image of the bottle man being squeezed, then there’s the idea that someone could put it in your drinks without you even being aware of it. That sure sounds like a great idea to promote. They try to sell it by explaining it has “the marvelous effect of producing a repugnance to alcohol in any shape or form.”

And it’s guaranteed to be safe? Of course it is. Thank goodness for that, it hadn’t even occurred to me to wonder until they brought it up. And let’s all beware of imitations, only get genuine Coza powder from the Institute itself, the “only genuine powder for Drunkenness.”

Sounds reasonable, right? Not everybody thought so, even at the time. No less than The British Medical Journal took a look at what was in Coza powder, among other such remedies of the day and in 1909 published their findings in an article entitled “The Composition Of Certain Secret Remedies.” On the page concerning the cure for drunkenness, the first one they examined was Coza powder:
coza-jstor
Not surprisingly, the BMJ found that Coza powder was nothing more than bicarbonate of soda, cumin, and cinnamon. And essentially it’s 90% sodium bicarbonate and the remaining 10% is equal parts cumin and cinnamon. They put the cost — in 1909 — at 1/30th of a penny for 30 packages of the powder.

I don’t know if this is relevant, but in Portuguese, “coza” means “bake.”

Benefit For Pete’s Sake At Spartan Stadium In San Jose

You may not have heard the name of Peter Cogan. He’s not a household name, not a rock star brewer and does not make a point of making sure people know who he is. He just does his job, and makes things happen. Born in England, Peter has been helping promote the beer scene in the South Bay as long as anybody can remember and has been working for Hermitage Brewing and the Tied House in Mountain View since 1990. He also helped launch the beerfest there, one of the biggest and most important early Bay Area beer festivals.

So what does that have to do with a beer festival on November 19 called “For Pete’s Sake?” Well, recently Peter was diagnosed with cancer, specifically lymphoma, and is undergoing chemotherapy treatment to beat back his cancer. For Pete’s Sake is a benefit to the Leukemia & Lymphoma Society (LLS), and also for Peter. Take my word for it, Peter is a great person and if there’s any stranger you help this year, let it be him. But besides a great cause, it should be a great time, too.

Your ticket includes admission to see the San Jose Spartans play Air Force in college football, plus a beer festival with unlimited samples from at least twenty local breweries. This all takes place on Saturday, November 19, 2016 at Spartan Stadium, located at 1257 South 7th Street, CEFCU Stadium, in San Jose. The brewfest starts and 2:30 PM and lasts for four hours, until 6:30 PM. Then at 7:30 PM, the game kicks off, and you’ll have a seat on the 50 to 30 yard line. Tickets are $40 in advance, and $50 on the day of the event. Tickets are available online. Use the promo code “FORPETESSAKE2016.” Visit the For Pete’s Sake Brewfest webpage for all of the details.

So even if you’ve never met Peter, if you’ve ever enjoyed a craft beer in the Bay Area, you probably owe him at least a small debt of gratitude. And what better way to thank him then to attend a beer festival and drink some more beer and have a great time. Is that too much to ask? Let’s all help Peter beat cancer.

The Ballmer Peak

October 28, 2016 By Jay Brooks

ballmer-peak
I was unaware of the Ballmer Peak (named for Microsoft’s 30th employee and former CEO Steve Ballmer) until today, but it’s an interesting idea, although there are some who believe it just may be an elaborate joke. In a nutshell, it’s the idea “that having a BAC in the 0.129% – 0.138% range can improve your cognitive abilities,” and it’s supposedly an effective technique to help with computer programming. Another way it’s been described is that “alcohol improves cognitive ability, up to a point,” and that it’s apparently a variation of the Yerkes–Dodson law, which says “that performance increases with physiological or mental arousal, but only up to a point.” xkcd described it with this cartoon:

ballmer_peak

Obviously, it may sound like bunk, but there has been earlier evidence of Creativity & Beer and also Caffeine Vs. Alcohol: Which One Better Enhances Creativity?. There’s also a lot of anecdotal evidence that alcohol can trigger creativity and/or create the conditions for new types of thinking to occur if in that sweet spot of not too drunk, and not too sober. Certainly there’s a rich historical record of books and songs created by writers and composers who were under the influence. And there was a great Bill Hicks bit about how if you think there are no positive aspects to drugs, he suggests burning all of the music that you love, because so many of the musicians who wrote it were “really fucking high.” Naturally, Bill put it much better than I ever could:

“You see, I think drugs have done some good things for us. I really do. And if you don’t believe drugs have done good things for us, do me a favor. Go home tonight. Take all your albums, all your tapes and all your CDs and burn them. ‘Cause you know what, the musicians that made all that great music that’s enhanced your lives throughout the years were rrreal fucking high on drugs. The Beatles were so fucking high they let Ringo sing a few tunes.”

Recently, however, there was an article in the Observer whose headline was “The Ballmer Peak Is Real, Study Says.”

A recent study at the University of Illinois tested the creative problem solving ability of a group of men who were given vodka cranberry and snacks and asked to solve brain teasers. The results were starkly different for the tispy group, which had a blood alcohol concentration level of 0.075, versus the control group:
Astonishingly, those in the drinking group averaged nine correct questions to the six answers correct by the non-drinking group. It also took drunk men 11.5 seconds to answer a question, whereas non-drunk men needed 15.2 seconds to think. Both groups had comparable results on a similar exam before the alcohol consumption began.
The study notes that the Ballmer Peak effect was present for creative problem solving but not for working memory.

balmers-peak-for-programmers

Also, on the skeptics forum on Stack Exchange, someone asked if the Balmer Peak was real, and one of the answers posted was this:

[An] article by Norlander [link no longer working] specifically studies the relationship between moderate alcohol consumption (1.0ml/kg body weight) and creativity. According to my very rough calculations, this would correspond to a BAC in the range of 0.12–0.14 for a 73kg human. The paper concludes
…modest alcohol consumption inhibits aspects of creativity based mainly on the secondary process (preparation, certain parts of illumination, and verification), and disinhibits those based mainly on the primary process (incubation, certain parts of illumination, and restitution).
In other words, moderate alcohol consumption does improve certain types of creative thinking, while inhibiting other types of creative thinking. Since the skills required for computer programming are solely cognitive in nature (discounting the motor skills required to type, of course), and given that creativity is a large part of computer programming, it is at least plausible that one might gain some amount of improvement from alcohol consumption.
There have also been studies on the relationship between alcohol consumption and creative output. That study examined 34 well known, heavy drinking, 20th century writers, artists, and composers/performers. It concludes:
Analysis of this information yielded a number of interesting findings. Alcohol use proved detrimental to productivity in over 75% of the sample, especially in the latter phases of their drinking careers. However, it appeared to provide direct benefit for about 9% of the sample, indirect benefit for 50% and no appreciable effect for 40% at different times in their lives. Creative activity, conversely, can also affect drinking behavior, leading, for instance, to increased alcohol consumption in over 30% of the sample. Because of the complexities of this relationship, no simplistic conclusions are possible.
So for a small portion of people there was a notable increase in creative output as a result of alcohol intake. It does appear that the study did not control for the quantity of alcohol intake, though, so this may not be directly applicable to the Ballmer Peak.
The best study I was able to find on the subject was by Lapp, Collins, and Izzo. They gave subjects vodka tonics of varying strengths (by varying the ratio of tonic to vodka), some of which did not even contain any alcohol. The subjects believed that they were drinking a standard-strength vodka tonic. The subjects then were asked to perform a number of cognitively and creatively challenging tasks. Here is what they conclude:
The present results support the idea that creative people probably gain inspiration from consuming alcohol …, but show that this effect may be due to the expected rather than the pharmacological effects of the drug. … A convergence of evidence supported the idea that creativity is enhanced (at least in some aspects) by the expected effects of alcohol.
In other words, alcohol can improve certain aspects of one’s cognitive ability, but this effect is not likely due to any pharmacological process (i.e., it is often sufficient to merely believe that one is drinking alcohol in order to achieve the same benefit).
And remember: The Ballmer Peak, as it is currently understood, is but a two dimensional projection of what in reality is a higher dimensional space, vi&.

The Ballmer Peak-a-Thon even has a Ballmer Calculator you can use to determine how much to drink to reach maximum effectiveness.
