Patent No. WO2012011807A1: A Method Of Stabilising Yeast Fermented Beverages

Today in 2012, US Patent WO 2012011807 A1 was issued, an invention of Tom Reinoud Noordman, Anneke Richter, and Marcel Van Der Noordt, assigned to Heineken Supply Chain B.V., for their “A Method of Stabilising Yeast Fermented Beverages.” Here’s the Abstract:

The present invention provides a method of preparing a yeast fermented beverage, said method comprising the steps of: a. fermenting wort with a biologically active yeast to produce a fermented liquid containing yeast, alcohol, polyphenols and protein; b. optionally removing yeast from the fermented liquid; c. combining the fermented liquid with polyvinylpolypyrrolidone (PVPP) particles to bind at least a fraction of the polyphenols and/or the proteins contained in the fermented liquid to said PVPP particles, at least 80 wt.% of said PVPP particles having a diameter in the range of 5-300 µm; d. removing a slurry containing the PVPP particles from the fermented liquid; e. filtering the slurry over a filter having a pore size in the range of 0.1-80 µm to produce a PVPP-enriched retentate and a PVPP-depleted filtrate; f. regenerating the PVPP particles contained in the PVPP-enriched retentate by desorbing polyphenols and/or protein from said PVPP-particles and separating the desorbed polyphenols and/or the desorbed protein from the PVPP particles; and g. after optional further refining of the regenerated PVPP particles, recirculating the regenerated PVPP particles to step c. The method can be operated with single use PVPP as well as regenerable PVPP. Furthermore, the present method does not require capacious filter hardware for regenerating the PVPP. The invention further provides an apparatus for carrying out the aforementioned method.


Patent No. 5384135A: Process For The Manufacture Of An Alcohol-Free Beer Having The Organoleptic Properties Of A Lager Type Pale Beer

Today in 1995, US Patent 5384135 A was issued, an invention of Henri J. J. Caluwaerts, assigned to Brasserie Du Cardinal Fribourg S.A., for his “Process for the Manufacture of an Alcohol-Free Beer Having the Organoleptic Properties of a Lager Type Pale Beer.” Here’s the Abstract:

A process for the manufacture of an alcohol-free pale beer (AFB) whose organoleptic properties are those of a lager beer, comprising the manufacture of a lager type alcoholic pale beer from pale malts containing 20 to 30% of brown malts, mashed to obtain a wort whose attenuation is of the order of 50% and the dealcoholization of the alcoholic pale beer, by evaporation, under high vacuum, of at least about 50% of the volume of this beer. The concentrate obtained by evaporation may be rediluted with water, flavored and sweetened until a concentration of 4° Brix is obtained in order to produce the AFB. The concentrate may also be subjected to a second vacuum evaporation at a temperature of less than 60° C. until a concentrate assaying between 45° and 65° Brix is obtained which is storable for several months before the redilution into an AFB.


Patent No. 1015585A: Keg Rinser

Today in 1912, US Patent 1015585 A was issued, an invention of George D. Prentice, for his “Keg Rinser.” There’s no Abstract, although in the description it includes this summary:

My invention relates to improvements in machines for rinsing kegs, and it pertains to that class which are adapted to be used with water under pressure.

The object of my invent-ion is to provide a machine by which a water controlling valve is automatically opened by the gravity of the keg to be rinsed, and the water supply is used for the two fold purpose of rinsing the kegs and removing them from the machine, whereby the operator has simply to place a”keg upon the machine when a water controlling valve will be automatically opened and the keg will be rinsed and automatically removed, whereby the manual labor of cleansing kegs is reduced to the minimum.


Patent No. 810745A: Method Of Pasteurizing Beer

Today in 1906, US Patent 810745 A was issued, an invention of Hugo Gronwald, for his “Method of Pasteurizing Beer.” There’s no Abstract, although in the description it includes this summary:

I have invented a new and Improved Method of Pasteurizing Beer in Barrels, of which the following is a full, clear, and exact description.

The hitherto-known method of pasteurizing beer in the barrels in which it is to be transported had the disadvantage that when the barrels were provided with a separate expansion-chamber the natural carbonic acid contained in the beer was`partly lost and the germs or barm at times contained in this chamber could not be killed, so that the beer frequently overflowing into this chamber was not entirely free from germs, while when the necessary space for expansion was provided by not filling the barrel complete y it had to be filled up with beer from another source. These disadvantages are removed according to my improved method by dividing the quantity of beer required for completely filling the barrel between two connected vessels-namely, a lower detachable vessel, hereinafter called receiver, equal in capacity to the required space for expansion and a barrel communicating with and arranged above this vessel in such a manner that the receiver is completely filled, while in .the barrel an empty expansion-space is left equal to the capacity of’ the receiver. The beer is then pasteurized in the barrel and receiver and cooled in the usual way, after which the carbonic acid disengaged during the pasteurizing and which as risen into the. expansion-space in the barrel can be returned Without loss to the beer-‘for instance, by shaking the barrel. T he pasteurizing apparatus being then turned upside down, the beer runs into the barrel from the receiver, while the excess of carbonic acid mounts into the receiver, so that by this simple exchange of the contents of the vessels a filling up of the beer-barrel from another source is rendered unnecessary and loss of carbonic acid is avoided.

Various apparatus or plant may be used for carrying out my said method, provided the barrel and receiver are connected into a combined apparatus.


Patent No. 981768A: Jetting Attachment For Bottle-Fillers

Today in 1911, US Patent 981768 A was issued, an invention of Alvin N. Ketterer, for his “Jetting Attachment For Bottle-Fillers.” There’s no Abstract, although in the description it includes this summary:

My invention relates to improvements in jetting attachments which are designed to control and direct jets of beer into bottles, one at a time in succession; the objects of which are to provide an attachment of this class, which can readily be attached to the discharge chute of beer bottle fillers now. Further objects are to so construct a jetting device that the same shall be extremely. simple, substantial and durable, and not liable to get out of order, be extremely cheap in cost of manufacture, and require but little attention or care.


Patent No. 270844A: Beer-Cooler

Today in 1883, US Patent 270844 A was issued, an invention of Friedrich Richter, for his “Beer-Cooler.” There’s no Abstract, although in the description it includes this summary:

My invention relates to beer-coolers, and will be fully described hereinafter.

Heretofore with coolers constructed according. to the plan in general use the ends of the pipes through which the cooling-liquid passes have been united by means of elbows, and as the beer or other liquid to be cooled had to be poured into pans or troughs at the top to flow through perforations in said troughs down over and around the pipes to a pan at the bottom of the cooler, that it might be deprived of its heat in this passage, it has been found difficult to keep the pipes clean, owing to their many elbows, and hence my invention, the object of which is to simplify the connections be tween the pipes, dispenses with the elbows altogether and presents a solid, smooth surface at each end of the beer-cooler, and at the same time unites the parts by such connections as will .admit of the cooler being easily taken apart when it is to be cleaned or repaired.

Another object of my invention is to provide a means for controlling the flow of the cooling-fluid, all as will be fully set forth farther on.


Historic Beer Birthday: Joseph Junk

Today is the birthday of German-born Joseph Junk (January 15, 1841-1887) who emigrated to the U.S. in 1868, and in 1883 opened the eponymous Joseph Junk Brewery in Chicago, Illinois. Unfortunately, he died just a few years later, in 1887, and his widow, Magdalena Junk, took over management of the brewery, renaming it Junk’s Brewery and then the Jos. Junk Brewery, which it remained until 1909. She increased production from around 4,000 barrels to 45,000 barrels of lager beer.

It then became the South Side Brewing Co. until prohibition, and afterwards reopened under that same name. But in 1937 in became the more fancifully named Ambrosia Brewing Co., then changed again one final time, to the Atlantic Brewing Co., before closing for good in 1965. It was located at 3700/3710 South Halstead and 37th Streets. According to Tavern Trove, “the brewery has been torn down. What was the Ambrosia Brewery is now the parking lot for Schaller’s Pump, a tavern located at 3714 S. Halsted, Chicago.”

Here’s a short article from the Western Brewer (Brewer’s Journal) from August 1909 reporting on the transition from Jos. Junk to South Side Brewing.


I was unable to find any photos of any of the Junk family, and in fact very little of anything, which I guess makes sense since they were the Junk Brewery, or some variation, for a relatively short time a very long time ago. Here’s what I did find.

A rare Junk bottle.

This is a South Side delivery truck taken around 1936.

The website where I found this claims it was from 1930, but American Breweries II states that it wasn’t called Ambrosia Brewing until 1937, so it’s probably from the late 1930s at the earliest. But another source says it’s from the 1950s, and indeed it as known as Ambrosia through 1959, so that’s perhaps more likely given the look of the postcard.

This is in the collection of the Chicago History Museum, but they appear to have no idea when it was taken.


This is the brewery around 1952, taken by Ernie Oest and featured at beer can history.

But by far, this is the most interesting bit of history on Joseph Junk I turned up. This is a newspaper article from the Chicago Tribune for March 29, 1902. It concerns what I can only assume is Joe and Magdalena’s son, since they refer to him as a “young man” and “member of the Chicago Brewery” rather then saying “owner.” Seems the young man went on a bender in San Francisco and ended up marrying some floozy he’d just met. But here’s the best bit. “The trouble began when the young man’s family learned that Lottie (is that not a floozy’s name?) had done a song-and-dance turn in abbreviated skirts.” Oh, the horror. It sounds like they could live with or tolerate the “song-and dance turn,” but not, I repeat not, if there were “abbreviated skirts” involved. That was the deal breaker, so they sent him off on “a Southern tour” and her packing back to Frisco, eventually settling on a payoff on $10,000, which in today’s money is over a quarter-million dollars, or roughly $276,150. It must have been the talk of polite society for months afterwards, bringing shame down on the Junk family.


Patent No. 5079927A: Beer Cooling Apparatus

Today in 1992, US Patent 5079927 A was issued, an invention of A. J. Rodino and James R. Kinkaide, for their “Beer Cooling Apparatus.” Here’s the Abstract:

A method and apparatus is provided for dispensing beer from a keg without excess foaming wherein the keg and beer temperatures and fluid pressures are controlled such that beer is dispensed at predetermined temperatures at substantially atmospheric pressures even over a wide range of atmospheric temperatures. Beer is supplied under pressure from the keg to a constricted flow line which abruptly decreases flow pressure. A portion of the constricted flow line is immersed in a refrigerating bath to reduce beer temperature. The length of the constricted flow line to the dispensing nozzle is sufficient long and its internal diameter sufficiently smooth that beer flow therethrough is stabilized to significantly reduce turbulence. Beer pressure drop through the nozzle is minimal and beer flow is relatively laminar.

The portion of the constricted line immersed in the refrigerating bath is formed from coiled tubing. The bath fluid is recirculated and the bath temperature is sufficiently low as to cause ice to form. The constricted line has a constant internal diameter throughout its length, and the dispensing nozzle has that same internal diameter. A portable embodiment includes a wheeled trailer for supporting and sheltering the keg.


Patent No. EP0208450A2: Beer Filtration

Today in 1987, US Patent EP 0208450 A2 was issued, an invention of Ronald Shackleton, for his “Beer Filtration.” Here’s the Abstract:

It has been proposed to filter beer or tank bottoms using crossflow filtration. In accordance with the invention, this crossflow filtration is achieved using ceramic membranes. In a particular form shown in figure 1, a two stage filtration process combines the functions of clarification and recovery from tank bottoms. Beer is drawn from a tank 1 by a centrifugal pump 2 to a primary filtration stage comprising a circuit in- cludinga a circulating centrifugal pump 3, a ceramic membrane filter 4 and a cooler 5. A proportion of the circulating liquid is drawn off by a positive pump 8, and passed to a secondary filtration stage, again comprising a circuit including a circulating positive pump 9, a ceramic membrane filter 11 and a cooler 12. A proportion of the retentate is drawn off via a line 14. This retentate is of a pasty consistency and normally has a commercial value, in that it is free of kieselguhr or other filter aid.


Historic Beer Birthday: Henry Shlaudeman

Today is the birthday of Henry Shlaudeman (January 13, 1834-February 24, 1923), who founded what would become the Decatur Brewing Co., in Decatur, Illinois. Shlaudeman was born in Wildeshausen, Grossherzogtum Oldenburg, in what today is part of Germany. He emigrated to America in 1846. After a short stint in the cigar trade, he joined the Edward Harpstrite Brewery (which was originally the John Koehler & Adam Keck Brewery when it opened in 1855). Within a few years, he’d made enough of an impact that it became the Harpstrite & Shlaudeman Brewery, and two years after that, in 1884, he bought out his partner and it became the Henry Shlaudeman Brewery. In 1888, it was again renamed, this time the Decatur Brewing Co. It reopened after prohibition in 1934 under the name Macon County Beverage Co., but closed for good the same year.


Surprising, I was unable to turn up even one photograph of him, and very little even of the brewery he owned. The City of Decatur and Macon County, subtitled “A Record of Settlement, Organization, Progress and Achievement,” includes a biography of Henry Shlaudeman:


And while there’s not much about him, his house has an entire webpage, all about the Henry Shlaudeman House


He also held two patents related to brewing. One was for an Improvement in safety-valves for fermented-liquor casks from 1878 and the other for a Refrigerator-building for fermenting and storing beer.
