By

patent-logo
Today in 1936, US Patent 2033326 A was issued, an invention of William F. Clark, for his “Method of Impregnating Beer Wort with Yeast.” There’s no Abstract, but it’s described in the introduction:

This invention which relates generally to the art of brewing is concerned with certain improvements in a method of and apparatus for produce ing beer or any liquid in which fermentation is an essential part of the process. For its objects, my invention aims to accelerate the fermenting process by the maintenance of conditions most favorable for the purpose, the utilization of apparatus which is simple, relatively inexpensive, and compact in size, and the production of a brew which is uniform at all times, which is superior in taste and flavor, which is free from turbidity and improved as to clarity, and in which a lesser amount of yeast or other fermenting agent is required.

Patent No. 6032571A: Automated Home Beer Brewing Machine And Method

By

patent-logo
Today in 2000, US Patent 6032571 A was issued, an invention of Brad Brous, Curt N. Torgerson, Terry Dubson, and Craig A. Wright, for their “Automated Home Beer Brewing Machine And Method.” Here’s the Abstract:

An automated home beer brewing machine and method makes beer in a single vessel under automatic control. The machine and method allows making of wort for beer without requiring apparatus to be sanitized, without boiling the wort, without the use of a traditional water-filled fermentation lock, and without using a wort chiller or ice-packing of a brewing pot. The inventive single-vessel automated brewing operation allows the user to load ingredients, conduct a grain-steeping if desired, and then automatically carries out the rest of the brewing process in a single vessel, until summoning the user days later to sugar-prime and bottle the beer. Thus, the user is required to provide much less time and labor than conventional home beer brewing, and the invention also frees the home-hobby brewer of much of the current art traditionally attached to home brewing.

Patent No. 3022617A: Conveyor Keg Palletizing Device

Today in 1962, US Patent 3022617 A was issued, an invention of John Miller and Vincent J. Russoman, assigned to Schaefer Brewing Co., for their “Attachment for Conveyor Keg Palletizing Device.” There’s no Abstract, and given that there are a record (for me at least) 45 drawings showing the patented device, there’s precious little by way of description, so I guess just look at the pretty pictures.

Patent No. 2782013A: Lauter Tubs

By

patent-logo
Today in 1957, US Patent 2782013 A was issued, an invention of Edwin L. Dittrich, assigned to Pfaudler Co. Inc., for his “Lauter Tubs.” There’s no Abstract, and the OCR didn’t work very well on this one, so it’s hard to read. What I can make out is that “this invention relates to lauter tubs and has for its object to provide several improvements thereto.

A lauter tub is essentially a device for straining wort liquid from the mash-grains; and comprises -a perforated false bottom resting on and separated from the tank bottom itself by spacer studs attached to the false bottom. The tank bottom is provided-with suitable drainage openings. The invention provides a combined gear drive and hydraulic system unit motivating the shaft which revolves in a universal bearing attached to the bottom of the tank, said shaft having vertical freedom of movement through out lifting the false bottom.”

Patent No. 3867551A: Preparation Of Beer

By

patent-logo
Today in 1975, US Patent 3867551 A was issued, an invention of Yves Germain Jaegle, for his “Preparation of Beer.” Here’s the Abstract:

Beer is prepared by a process wherein groups of batches of wort are turned serially at temperatures increasing from 10 DEG to 14.5 DEG C into a cylindrical, vertically disposed vat having a conical bottom. Convection currents are instituted to homogenize the contents of the vat and fermentation is carried out until a beer of the desired degree of fermentation is formed. The resultant beer is mellowed by a warm keep phase, cooled and subjected to a cold keep phase.

Patent No. 5718161A: Beer Brewing System And Method

By

patent-logo
Today in 1998, US Patent 5718161 A was issued, an invention of Leigh P. Beadle, for his “Beer Brewing System And Method.” Here’s the Abstract:

There is provided a system for brewing beer particularly suited for a brew pub setting. The invention utilizes a cooker to heat water and a pre-blend syrup of ingredients. Once the beer mixture is boiled for a sufficient length of time in the cooker, the mixture is transferred to a brewing vessel. A spiral spray nozzle is used to add water to the brewing vessel in a conical spray pattern which causes the water to be oxygenated once it passes through the spiral spray end of the nozzle. Yeast is added to the brew mixture and oxygenated water in the brewing vessel. The beer mixture is permitted to ferment in the brewing vessel for a sufficient length of time. The fermented beer mixture is transferred to a plurality of kegs, each of which contains a mixture of sugar and gelatin. The sugar and gelatin allow the beer mixture and age and clarify. Once the beer mixture has aged a sufficient time, the beer mixture is dispensed from the kegs. The system of the invention includes a keg cleaning device for simultaneously depressurizing the keg while hooking up the device to the keg.

By

patent-logo
Today in 1906, US Patent 812243 A was issued, an invention of Max Stahl, for his “Circulating System for Beer-Filters.” There’s no Abstract, but Stahl describes his invention as an improvement over then-current systems, saying his “invention aims to and does overcome the losses and disadvantages [mentioned earlier in the description], and in brief it consists of providing means whereby the column of beer can be switched off the racking-bench and continuously returned to the filter until stable relations are secured and the beer no longer runs cloudy or contains fibers of filter mass.”
