Thursday’s ad is for “Rheingold Beer,” from 1951. This ad was made for the Rheingold Brewery, which was founded by the Liebmann family in 1883 in New York, New York. At its peak, it sold 35% of all the beer in New York state. In 1963, the family sold the brewery and in was shut down in 1976. In 1940, Philip Liebmann, great-grandson of the founder, Samuel Liebmann, started the “Miss Rheingold” pageant as the centerpiece of its marketing campaign. Beer drinkers voted each year on the young lady who would be featured as Miss Rheingold in advertisements. In the 1940s and 1950s in New York, “the selection of Miss Rheingold was as highly anticipated as the race for the White House.” The winning model was then featured in at least twelve monthly advertisements for the brewery, beginning in 1940 and ending in 1965. Beginning in 1941, the selection of next year’s Miss Rheingold was instituted and became wildly popular in the New York Area. Elise Gammon was elected Miss Rheingold for 1951. She was born in Miami, Florida in 1930, though I was unable to find her birthday, it’s not even mentioned in her obituary when she passed away in 2014. She attended Florida State and Harcum College in Pennsylvania, before moving to new York City to pursue a modeling career. At the end of 1950, she married Edward Ory of Louisiana. The pair met on the television show “Blind Date.” As far as I can tell that marriage didn’t last very long because in her obituary, it only mentioned she later moved back to Miami and met and married Fatio O’Hearn Dunham, I think around 1964, and they had four children together, eventually settling in Lakeland in 1980. In this ad, from September, she’s playing polo and talking about inscutable the jargon is in polo, contrasting it with how easy it is to understand good beer.

Historic Beer Birthday: Hans Adolf Krebs
Today is the birthday of Hans Adolf Krebs (August 25, 1900-November 22, 1981). He was a German-born British physician and biochemist. He was the pioneer scientist in study of cellular respiration, a biochemical pathway in cells for production of energy. He is best known for his discoveries of two important chemical reactions in the body, namely the urea cycle and the citric acid cycle. The latter, the key sequence of metabolic reactions that produces energy in cells, often eponymously known as the “Krebs cycle,” earned him a Nobel Prize in Physiology or Medicine in 1953. And it’s the Krebs cycle that is his relation to brewing, as it’s also known as the respiratory phase, the second aerobic state of the fermentation process immediately following the lag period.
Here’s a description of the Krebs cycle from Life Fermented:
The Krebs cycle, also known as the tricarboxylic acid (TCA) cycle or the citric acid cycle, is a circular and repeating set of reactions which requires oxygen. In beer making, this would occur in the first stage of fermentation when the yeast is pitched into a well aerated wort, and carries on until all oxygen is used up.
Pyruvate (are you tired of this word yet?) is first converted to acetyl-CoA (pronounced “Co-A”) in the following reaction:
pyruvate + 2 NAD+ + CoA-SH → acetyl-CoA + CO2 + NADH, with the help of the pyruvate dehydrogenase (PDH) complex. Note that this is the first time CO2 is produced, and yet more NADH is generated.
This acetyl-CoA then enters into a cycle of reactions which nets two molecules of CO2, one GTP (guanosine triphosphate, another unit of energy equivalent to ATP), three NADH, and one FADH2 (flavin adenine dinucleotide, which functions similarly to NADH). After the cycle completes, another acetyl-CoA molecule enters and the cycle repeats itself.
But wait, this just made more NADH, and we need to regenerate NAD+ so glycolysis can continue. Both the NADH and FADH2 now donate their electrons to a process called the electron transport chain/ oxidative phosphorylation. The result is a return of NAD to the NAD+ state, and a large amount of ATP cellular energy.
Because the Krebs cycle is so efficient at producing ATP energy units, this is the yeast’s preferred pathway. But, you’ll notice a rather conspicuous absence: ethanol. This is only formed in the absence of oxygen.
Here’s a biography of Krebs, from the Nobel Prize website:
Sir Hans Adolf Krebs was born at Hildesheim, Germany, on August 25th, 1900. He is the son of Georg Krebs, M.D., an ear, nose, and throat surgeon of that city, and his wife Alma, née Davidson.
Krebs was educated at the Gymnasium Andreanum at Hildesheim and between the years 1918 and 1923 he studied medicine at the Universities of Göttingen, Freiburg-im-Breisgau, and Berlin. After one year at the Third Medical Clinic of the University of Berlin he took, in 1925, his M.D. degree at the University of Hamburg and then spent one year studying chemistry at Berlin. In 1926 he was appointed Assistant to Professor Otto Warburg at the Kaiser Wilhelm Institute for Biology at Berlin-Dahlem, where he remained until 1930.
In I930, he returned to hospital work, first at the Municipal Hospital at Altona under Professor L. Lichtwitz and later at the Medical Clinic of the University of Freiburg-im-Breisgau under Professor S. J. Thannhauser.
In June 1933, the National Socialist Government terminated his appointment and he went, at the invitation of Sir Frederick Gowland Hopkins, to the School of Biochemistry, Cambridge, where he held a Rockefeller Studentship until 1934, when he was appointed Demonstrator of Biochemistry in the University of Cambridge.
In 1935, he was appointed Lecturer in Pharmacology at the University of Sheffield, and in 1938 Lecturer-in-Charge of the Department of Biochemistry then newly founded there.
In 1945 this appointment was raised to that of Professor, and of Director of a Medical Research Council’s research unit established in his Department. In 1954 he was appointed Whitley Professor of Biochemistry in the University of Oxford and the Medical Research Council’s Unit for Research in Cell Metabolism was transferred to Oxford.
Professor Krebs’ researches have been mainly concerned with various aspects of intermediary metabolism. Among the subjects he has studied are the synthesis of urea in the mammalian liver, the synthesis of uric acid and purine bases in birds, the intermediary stages of the oxidation of foodstuffs, the mechanism of the active transport of electrolytes and the relations between cell respiration and the generation of adenosine polyphosphates.
Among his many publications is the remarkable survey of energy transformations in living matter, published in 1957, in collaboration with H. L. Kornberg, which discusses the complex chemical processes which provide living organisms with high-energy phosphate by way of what is known as the Krebs or citric acid cycle.
Krebs was elected a Fellow of the Royal Society of London in 1947. In 1954 the Royal Medal of the Royal Society, and in 1958 the Gold Medal of the Netherlands Society for Physics, Medical Science and Surgery were conferred upon him. He was knighted in 1958. He holds honorary degrees of the Universities of Chicago, Freiburg-im-Breisgau, Paris, Glasgow, London, Sheffield, Leicester, Berlin (Humboldt University), and Jerusalem.
He married Margaret Cicely Fieldhouse, of Wickersley, Yorkshire, in 1938. They have two sons, Paul and John, and one daughter, Helen.
And in the Microbe Wiki, on a page entitled “Saccharomyces cerevisiae use and function in alcohol production,” under a section called “Fermentation of alchohol,” the Krebs cycle is placed in its portion in the fermentation process:
Saccharomyces cerevisiae is able to perform both aerobic and anaerobic respiration. The process begins with the yeast breaking down the different forms of sugar in the wort. The types of sugars typically found in wort are the monosaccharides glucose and fructose. These sugars contain a single hexose, which is composed of 6 carbon atoms in the molecular formula C6H12O6. Disaccharides are formed when two monosaccharides join together. Typical disaccharides in the wort are galactose, sucrose, and maltose. The third type of fermentable sugar in the wort is a trisaccharide. This trisaccharide is formed when three monosccharides join together. Maltotriose is the trisaccharide commonly found in the wort and is composed of three glucose molecules. The wort does contain other sugars such as dextrins but it is not fermentable by yeast10. These dextrins contain four monosaccarides joined together. In order for the yeast to use the disaccharides and trisaccharides they first must be broken down to monosaccharides. The yeast does this by using different enzymes both inside and outside the cell. The enzyme invertase is used to break down sucrose into glucose and fructose. The invertase catalyzes the hydrolysis of the sucrose by breaking the O-C (fructose bond). The other enzyme used is maltase, which breaks down maltose and maltotriose into glucose inside the cell. The enzyme does this by catalyzing the hydrolysis of the sugars by breaking the glycosidic bond holding the glucose molecules together.
Once the sugars are broken down into monosaccharides the yeast can use them. The primary step is called glycolysis. In this process the glucose is converted to pyruvate using different enzymes in a series of chemical modifications. The electrons from glucose end up being transferred to energy carrying molecules like NAD+ to form NADH. ATP is also formed when phosphates are transferred from high-energy intermediates of glycolysis to ADP. In the presence of oxygen aerobic respiration can occur. This occurs in the mitochondria of the yeast. The energy of the pyruvate is extracted when it goes through metabolic processes like the Krebs cycle. The products of this type of metabolism are ATP, H2O, and CO2. However if there is no oxygen present and an abundance of sugars, as in the wort, the yeast undergo alcoholic fermentation. This type of metabolism yields much smaller amounts of energy when compared to aerobic respiration. However, because of the large supply of sugars from the different grains the wort is a very good environment for fermentative growth. The alcoholic fermentation begins with the two pyruvate acquired from glycolysis. These two pyruvate are decarboxylated by pyruvate decarboxylase to form two acetaldehydes and CO2. The CO2 is the gas that is observed during fermentation as bubbles that float to the top of the wort creating the kräusen or beer head, the foam that is very characteristic of a freshly poured beer. Pyruvate decarboxylase is a homotetramer meaning it contains four identical subunits. This also means that is has four active sites. The active sites are where the pyruvate reacts with the cofactors thiamine pyrophosphate (TPP) and magnesium to remove the carbon dioxide9. The final step to form alcohol is the addition of a hydrogen ion to the aldehyde to form ethanol. This hydrogen ion is from the NADH made during glycolysis and converts back to NAD+. The ethanol is originally believed to serve as an antibiotic against other microbes. This form of defense ensures that bacteria do not grow in the wort, thus ruining the beer with off flavors. However recently with the boom of craft beer different bacteria have been purposefully added to create what is known as sour beer. The sour taste comes from the waste products of the bacteria.

Historic Beer Birthday: August Uihlein
Today is the birthday of August Uihlein (August 25, 1842-October 11, 1911). He was born in Wertheim am Main, Baden, Germany. He came to the U.S. with his grandfather and August was educated as a brewer in the U.S., working initially for the Uhrig Brewery in St. Louis. In 1867, he returned to Milwaukee, Wisconsin, where his grandfather had settled, and “joined what was now the Joseph Schlitz Brewing Company, the same brewery that had been founded by his uncle August Krug in the 1840s (Krug’s widow, Anna Maria, had married Joseph Schlitz in 1858).”
On the death of Schlitz in 1875, control of the firm passed into the hands of Uihlein and his brothers. When Mrs. Schlitz died in 1887, the Uihlein brothers acquired complete ownership of the corporation. Uihlein was secretary and chairman of the board (1874–1911). He was also actively involved in banking, real estate, and many other Milwaukee businesses.
Here’s a biography of August Uihlein from Find-a-Grave:
Brewer and business executive. He was the first of the Uihlein dynasty that owned and operated Joseph Schlitz Brewing Co. over the years. Born Georg Carl August Ühlein, son of Josef Benedikt Ühlein and Katherina Krug, in Wertheim am Main, Baden, Germany. At age eight he endured a rough immigration on the way to Milwaukee, Wisconsin, in 1850, traveling with his grandfather, Georg Krug. He survived the mid-Atlantic fire and sinking of the S.S. Helene Schlomann, during which his grandfather managed to save him and $800 in gold that was subsequently used to expand his uncle August Krug’s brewery and to hire a bookkeeper, Joseph Schlitz. He attended Milwaukee’s German-English Academy, then studied at St. Louis University in Missouri (1855 to 1857). His uncle, August Krug, died in 1856 and Schlitz became the manager of the brewery and two years later married Krug’s widow and changed the name to Joseph Schlitz Brewing Co. In 1858, at age 16, Uihlein convinced Schlitz to hire him as a bookkeeper after only 60 days training in the subject in St. Louis. August proposed to take a company inventory and revamp the brewery’s accounting system from single to double-entry bookkeeping. While holding down a full-time job (age 17) at the Second Ward Savings Bank (now First Wisconsin) without salary, he applied this training to the brewery’s accounting during evenings. For his efforts at the bank, he received a gold pen from Valentine Blatz after a year of service. He then worked the Uhrig Brewery in 1860 in St. Louis (the Uhrig family had a summer home in Milwaukee) as a bookkeeper, collector, and shipping clerk for $20 a month and two years later, shortly before his 20th birthday, he was promoted to the position of general manager. Returning to Milwaukee in 1867, he became the bookkeeper for the Joseph Schlitz brewery, and on the death of Schlitz in 1875, management control of the firm passed into the hands of him and his brothers, all nephews of the brewery’s original founder, August Krug. Along with his brothers Henry and Edward, he continued the business strategies initiated by Schlitz. The company developed a system of agencies across the United States to sell beer, and developed its own vast rail distribution network. When Mrs. Schlitz died in 1887, the Uihlein brothers acquired complete ownership of the enterprise. From a ranking of tenth largest US brewer in 1877, their national marketing plan propelled the company to third by 1895. Sitting among the top three breweries was little comfort when prohibition came about. The company met the challenge as did others, restructuring the brewery as Joseph Schlitz Beverage Co. to produce near beer, yeast, soft drinks, malt syrup and a chocolate candy named “Eline” (a phonetic play on the family name). Returning to brewing in 1933, the company launched an acquisition plan and new construction that led them to second and then first place in US beer production. For the next 40 the years the company would remain near the top and at one point was ranked as the largest in the world. August Uihlein was Schlitz company secretary from 1874 and also chairman of the board from 1880 until his death in 1911, and was prominently identified with banking, real estate, and many other Milwaukee enterprises. Interested in racing horses, he maintained a large stock farm near Kenosha and was the owner of the famous trotting-horse champion, “Harvester.” Noted for his local philanthropy, he donated large sums to the German-English Academy and to the Milwaukee Public Library. He died while visiting in Germany.

Historic Beer Birthday: George F. Klotter Jr.
Today is the birthday of George F. Klotter Jr. (August 25, 1835-1900?) His father, along with partner Johann G. Sohn, established the Hamilton Brewery in Cincinnati, Ohio in 1846. Klotter Sr. left that brewery, while Sohn continued alone, and Klotter started another brewery, the George Klotter Brewery in 1866 The following year George Jr., and his brother Louis, joined the brewery, and it was renamed the George Klotter and Sons Brewery, which it remained until 1888.
It 1888, it was renamed the Bellevue Brewery until finally closing in 1919.
