Publication number: 20230357677Abstract: A user interface for a beer recipe creator may have a series of icons that may represent ingredients. A user may drag and drop or otherwise add the icons to containers on a display screen to add or remove ingredients to the recipe. With each added or removed ingredient, a set of descriptors may be updated. The descriptors may include numerical values of beer parameters as well as textual descriptions and visual descriptions. The system may allow a user to start with a desired beer style, and the parameters may show variances from the selected style. The system may generate an ingredients list, as well as a brewing recipe that may be transferred to a controller for a beer making machine. The system may adjust certain parameters that are controllable by the beer making machine to make flavor and other adjustments selected by a user.Type: ApplicationFiled: July 13, 2023Publication date: November 9, 2023Applicant: PicoBrew, LLCInventor: William H.

Publication number: 20230348827Abstract: An automated or semi-automated beer brewing system may adjust recipes using a computer interface. The computer interface may present different characteristics of a beer and may allow a user to adjust the characteristics of the resulting beer. In many cases, the characteristics of the final product may be changed while keeping the original ingredients and their measurements the same. Characteristics such as mouthfeel may be adjusted from thick to thin by adjusting a mashing schedule to change the alpha amylase extraction. In another example, a characteristic of dry to malty may be adjusted by changing the amount of simple sugars that may be extracted during the mashing phase. A computer interface may present the characteristics in an interactive form, such as a slider, where a user may adjust the recipe prior to use.Type: ApplicationFiled: July 3, 2023Publication date: November 2, 2023Inventor: William H. Mitchell

Patent number: 11753610Abstract: An automated or semi-automated beer brewing system may adjust a brewing session based on data collected during the brewing session. The adjustments may attempt to achieve a set of desired taste characteristics, even though a brewing session may then deviate from an intended recipe. A performance model of the brewing system may include taste characteristic effects and operational aspects of an automated brewing system, and may be used to calculate changes to various brewing steps. A control system may analyze various measured parameters to determine deviation from an intended recipe, and may use the performance model to calculate updated brewing steps that may attempt to achieve the desired result. When such measured parameters indicate a malfunction, a brewing session may be paused or terminated.Type: GrantFiled: November 19, 2018Date of Patent: September 12, 2023Assignee: PB Funding Group, LLCInventor: William H.

Publication number: 20230235257Abstract: Alcoholic spirits may be artificially aged under highly pressurized carbon dioxide. The carbon dioxide may form carbonic acid, which may cause various esters to form in the presence of wood as well as to mellow the flavor when no wood is present. Wood may be pretreated with ozone, which may extract lignin which may further convert to vanillin during pressurized CO2 treatment, giving a vanilla note. After processing with pressurized CO2, a post-treatment of ozone may be given to the spirit, which may cause a mild oxidation and further mellowing of the spirit.Type: ApplicationFiled: April 3, 2023Publication date: July 27, 2023Inventors: James B. Mitchell, Avi R. Geiger, William H. Mitchell

Patent number: 11678760Abstract: A brewing device may have several different configurations to make various beverages. Under computer control, the device may be able to sequence various ingredients using direct or recirculating percolation for immediate consumption, such as coffee and tea, or for fermenting for later consumption, such as beer, kombutcha, or other consumable products. The device may be capable of a sequenced percolation, such as coffee infusion of a first type of coffee, then a second type of coffee, followed by vanilla, and followed by spices. The device may be capable of sequential, cascading, or parallel percolation directly or using recirculating paths. Ingredients may be pre-packaged or may be placed into various removable and cleanable containers. The device may further be capable of infusion by steeping ingredients in a dispensing device.Type: GrantFiled: March 12, 2018Date of Patent: June 20, 2023Assignee: PB Funding Group, LLCInventor: William H.

Publication number: 20210062121Abstract: A beer serving and fermentation device may have a refrigerated compartment in which beer vessels may be stored. The refrigerated compartment may be set to a first temperature, yet one or more of the vessels may have a heat blanket that may be cause the wrapped vessel to be at a higher temperature than the refrigerated compartment. The wrapped vessel may be controlled at a second, higher temperature for beer fermentation, while other vessels in the same compartment may be at a lower temperature for serving, for example. A controller may control the temperature of a fermenting vessel with a heating element inside a refrigerated compartment. The controller may increase or decrease the temperature of the fermenting vessel at various stages of the fermenting cycle, and may finish a fermentation cycle by allowing the fermenting vessel to chill to the temperature of the refrigerated compartment.Type: ApplicationFiled: August 29, 2019Publication date: March 4, 2021Inventors: William H.

Publication number: 20200157478Abstract: A beer making system may modify a beer ingredient/process recipe to adjust sensory characteristics of a desired beer. With a given ingredient list and starting recipe, a performance model of a brewing system may be used to generate an updated recipe when given a set of desired sensory characteristics of a desired beer. A user interface may permit a user to adjust characteristics such as thin/thick mouthfeel, dryness/maltiness, hops bitterness, hops flavor, hops aroma, and other characteristics. An updated recipe may change mashing schedules, boiling schedules, or other programmatically controlled aspects of a brewing system. The performance model may include heuristics as well as performance metrics derived from observing previous brewing sessions on one or multiple devices.Type: ApplicationFiled: June 23, 2019Publication date: May 21, 2020Inventor: William H.

Publication number: 20200151835Abstract: An automated or semi-automated beverage brewing machine may be programmed using individualized recipes that may be modified and stored based on user input. A user may receive a query or provide input regarding a beverage they may have consumed, and their input may cause the recipe for their beverage to be updated or changed. The updated recipe may be stored for use the next time the user may request the beverage. In some cases, a cell phone app may be used to select and modify a beverage recipe, as well as to collect the user's input after drinking the beverage. In other cases, an automated or semi-automated brewing machine may have an interface through which a user may select beverages and, in some cases, provide input regarding the beverage. A user's preferred recipe may be transferred to different beverage brewing devices whenever the user may request the beverage.Type: ApplicationFiled: November 14, 2018Publication date: May 14, 2020Applicant: PicoBrew, Inc.Inventor: William H.

Patent number: 10479966Abstract: A fermentation monitoring system may measure the weight of a fermenting product to determine the progress of fermentation. The weight of a fermenting batch may decrease as carbon dioxide is given off, and a continuous or periodic weight measurement may be used as a control input to a fermentation system, which may adjust temperature to control fermentation or detect that fermentation is not progressing as expected. Such a system may be to use a weight scale attached to a fermentation vessel and have a control system capable of adjusting the temperature of the fermenting contents. One implementation may have a scale mounted inside a temperature controlled fermentation cabinet.Type: GrantFiled: February 13, 2018Date of Patent: November 19, 2019Assignee: PicoBrew, Inc.Inventors: William H.
