Various embodiments can further include g the fermented mixture to about zero degrees Celsius and storing the ted mixture. In some embodiments, yeast finings are uced and the fermented mixture is filtered and carbonated such that beer is produced.
In the discussion that follows, a section ed "Producing Wort Concentrate" describes s ques for producing wort concentrate in ance with one or more embodiments. Next, a section entitled "Packaging Wort Concentrate" describes various techniques for packaging wort concentrate in accordance with one or more embodiments. A n ed "Producing Beer from Wort trate" describes techniques for using packaged wort concentrate to produce beer for consumption. Finally, a section entitled "Example System" describes an example system that can be used to implement one or more embodiments. . [0015] Consider, now, an e process for producing wort concentrate in accordance with one or more embodiments.
Producing Wort Concentrate Fig. 1 is a block diagram of an example process 100 for producing wort concentrate in accordance with one or more embodiments.
Block 102 mixes ients. Ingredients can include malted grain and water. .
Malted grain can be, for example, barley, wheat, rice, or other grains. In some embodiments, the malted grain can be crushed or milled. Other ingredients can be added, depending on the particular embodiment. The ingredients can be mixed in a mash tun or other vessel.
WO 31475 Block 104 mashes the mixture ofblock 102 at a first temperature. This can be performed in any le way. In various embodiments, the first temperature is a temperature of approximately 65 degrees Celsius. Mashing enables the s in the grain to t starches (e.g., long chain carbohydrates) from the grain into fermentable sugars. [This sion process is sometimes called "saccharification." Fermentable sugars can include, for example, glucose, maltose, and malotriose. In various embodiments, the-mixture is mashed for an amount of time between ten and thirty minutes. The particular time of mashing can vary depending on the particular embodiment.
Block 106 increases the temperature. This can be performedin any suitable way. For example, a brewer can increase the temperature manually or an automated system can be employed to se the temperature to a temperature between 73 and 74 degrees s. The particular increase in temperature can vary depending on the specific embodiment.
Next, block 108 mashes the mixture at the second temperature. This can be performed in any suitable way. For example, the e can be mashed for an amount of time between about thirty and about ninety minutes at a temperature between 73 and 74 degrees s. This secondary g can produce fermentable sugars and/or non—fermentable sugars. Non-fermentable sugars, such as DP4 and DP3 for example, can contribute to the body and mouthfeel of the final beer product.
Block 110 filters liquid off the mixture. This can be performed in any suitable way. For e, the wort can be strained through the bottom of the mash tun in a process sometimes referred to as ring" and transferred into another vessel. Other methods of filtering the wort from the mash mixture can be used, depending on the particular embodiment.
Next, block 112 adds hops to the wort. This can be performed in any suitable way. For example, hops can be added, with or without other ingredients such as herbs or sugars, to the wort to add flavor, aroma, and ness.
Block 114 boils the hops and wort mixture. This can be performed in any suitable way. For example, the hops and wort mixture can be boiled in the brew kettle for a predetermined amount of time effective to t hops from non-bitter compounds into bitter compounds. In various embodiments, the predetermined amount of time is between about 1 and about 3 hours. The particular amount of time can vary depending on the specific embodiment. In various embodiments, the hops and wort mixture is boiled effective to produce a wort concentrate having a specific gravity in a range from about 1.085 kg/m3 to about 1.095 kg/m3. 2012/000624 Finally, block 116 packages the wort concentrate. This can be performed in any suitable way, examples of which are provided above and below.
At least one result ofprocess 100 is a wort concentration having a specific gravity in the range of about 1.085 kg/m3 to about 1.095 kg/m3. By contrast, traditional wort concentrations have a specific gravity in the range of about 1.038 kg/m3 to about 1.060 kg/m3.
The increased specific y and concentration of the wort concentrate can be attributed at least in part to an increased boiling time over convention methods of wort production.
Having bed an example method ofproducing a wort concentrate, consider now a description of techniques for ing the wort concentrate.
Packaging Wort Concentrate Fig. 2 illustrates an example process 200 for packing wort concentrate in accordance with one or more embodiments. Process 200 can be employed, for example, by block 116 in Fig. 1.
Block 202 boils the wort. This can be performed in any suitable way. For example, wort can be boiled with hops, such as described above in nce to block 114.
Next, block 204 Whirlpools the wort. This can be med in any suitable way. For example, after boiling, the hopped wort can be settled to clarify, effective to separate out solid particles, including coagulated protein and hops compounds. In various ments, most or a majority of the solid particles are separated from the wort concentrate.
Block 206 acidifies the wort concentrate. This can be performed in any suitable way. For example, phosphoric or lactic acid can be added to the wort effective to acidifiy the wort to a pH of between about 2.0 and about 3.0. In various ments, sulfur is added to a level of 10ppm or more. This can be performed in any suitable way. For example, sodium metabisulphite and/or potassium metabisulphite can be added in an amount effective to adjust the sulfiJr level to 10ppm or more.
Next, block 208 cools the wort concentrate. This can be med in any suitable way. For example, the wort can be transferred from the whirlpool through a heat exchanger into a ter for cooling. Other methods of cooling wort concentrate can be used depending on the particular ment. In various embodiments, the wort concentrate is cooled to a temperature between about 58 and about 60 degrees Celsius. . [0032] Finally, block 210 packages the wort concentrate. This can be performed in any le way. For example, the wort concentrate can be packaged and shipped in ermined sizes, weights, or the like. For example, the wort concentrate can be packaged into 20 or 25 liter bags in boxes or a suitable one-way . In various embodiments, the wort trate is packaged at a temperature between about 58 degrees Celsius and about 60 degrees Celsius.
Process 200 can be used to package the wort concentrate such that the wort concentrate is substantially iologically stabilized. While various techniques included in process 200 can contribute to the stabilization and sterilization of the wort concentrate, a ntially microbiologically stable wort concentration can be achieved by using less than all of these techniques. For example, packaging the wort at a temperature between about 58 degrees Celsius and about 60 degrees Celsius can have a pasteurization effect. As another example, acidification of the wort concentration to a pH ofbetween about 2.0 and about 3.0 can have'a deleterious effect on bacteria and yeast to ze or even prevent bacterial and/or yeast growth or survival. In some embodiments, alternative techniques may be ed.
Once ed, the wort concentrate can be shipped to a retail outlet, such as a restaurant, bar, store, or the like, for use in producing beer.
Producing‘Beer from Wort Concentrate Fig. 3 is a block diagram of an example process 300 for producing beer from wort concentrate. The wort concentrate can be, for example, the wort concentrate produced by process 100 and packaged by process 200. In various ments, the wort concentrate can be ed based upon the end-type ofbeer desired, such as, for example, lager, dry, amber, stout, wheat, or the like. In various embodiments, process 300 can be med by an automated system.
Block 302 adds the wort concentrate, water, acid neutralizer, and yeast to a fermenter. In some embodiments, other ingredients may also be added. This can be performed in any suitable way. For e, a user can select a recipe from a system screen and a pre- determined amount ofwort concentrate can be pumped into a fermentation tank according to the selected recipe. Filtered water, an acid neutralizing on, and yeast can also be added to the fermentation tank. This can be performed by a user or automatically by the system. In embodiments when the mixture is formed by a system, the system can receive a user selection of a recipe and cause an appropriate amount of each ingredient to be added to the tank.
Block 304 ferments the mixture. This can be performed in any suitable way.
For example, in some ments, a user can push a "start" button when all ingredients have been added by block 302, or the system can automatically start fermentingupon the addition of ingredients. In various embodiments, temperature and carbon dioxide evolution are monitored during fermentation. Carbon dioxide evolution can be calibrated against specific gravity drop and subsequent alcohol development through a mass flow meter. In various embodiments, the mixture is ted until carbon dioxide ion reaches a pre-determined level.
Next, block 306 cools the ted e. This can be performed in any suitable way. For example, when monitored carbon dioxide levels indicate fermentation is substantially complete, temperature of the fermentation tank can be sed effective to cool the fermented mixture to a temperature between about zero and about four degrees s. In various embodiments, the fermented mixture is cooled at a temperature n about zero and about four s Celsius for about five to seven days. The time and temperature of cooling can vary depending on the particular embodiment.
Block 308 adds yeast finings. This can be performed in any suitable way. For example, after discharging waste yeast and cleaning system lines, yeast finings can be introduced into the fermentation tank. In various embodiments, yeast finings are added to the fermented mixture and the mixture is stored for about twenty-four hours.
Next, block 310 filters the mixture. This can be performed in any suitable way.
For example, the mixture can be d into a bright tank or another vessel. In various embodiments, filtration can occur automatically. In some embodiments, a pH meter, flowmeter, and pressure transducers can be used to monitor filtration.
Finally, block 312 carbonates the filtrate. This can be performed in any suitable way. For example, a carbon dioxide and time dependent regime can be implemented automatically upon transfer of the filtrate into the bright tank. Upon carbonation, the beer is ready for consumption. The beer can be, for example, packaged into cans, bottles, or kegs, or can be otherwise prepared for consumption.
The techniques described above can be implemented to produce beer from a wort concentrate. In various embodiments, the techniques can be ented by an automatic system such that a brew master need not be on-site to produce the beer. Consider the following example system that can be used to implement one or more embodiments.
Example System Fig. 4 depicts an example system 400 that can be used to implement one or more embodiments. For example, system 400 can be used to automatically produce beer from wort concentrate, such as described in example process 300.
System 400 includes input device 402 that may include Internet ol (IP) input s as well as other input devices, such as a rd. Other input devices can be used, such as a pressure transducer, pH meter, flow meter, and the like. System 400 further includes communication interface 404 that can be implemented as any one or more of a wireless interface, any type of network interface, and as any other type of communication interface. Through communication interface 404, system 400 can direct other components, such as fermentation tanks, bright tanks, filtration components, and the like, to be configured according to ular parameters. A network interface es a connection between system 400 and a communication network by which other electronic and ing devices can communicate data with system 400. A wireless interface can enable system 400 to operate as a mobile device for wireless communications.
System 400 also includes one or more processors 406 (e.g., any of microprocessors, llers, and the like) which process various computer-executable instructions to l the ion of system 400 and to communicate with other electronic devices. System 400 can be implemented with computer-readable media 408, such as one or more memory components, examples ofwhich include random access memory (RAM) and non-volatileimemory (e.g., any one or more of a read-only memory (ROM), flash memory, EPROM, EEPROM, etc.). A disk storage device may be implemented as any type of magnetic or optical storage device, such as a hard disk drive, a able and/or rewriteable compact disc (CD), any type of a digital versatile disc (DVD), and the like.
Computer-readable media 408 provides data storage to store content and data 410, as well as device executable modules and any other types of information and/or data ‘ related to operational aspects of system 400. The data storage to store content and data 410 can be, for example, storage of recipes for producing beer from wort concentrate and production routines to produce the beer. For example, various routines for times and temperatures of the fermentation tank can be stored as content and data 410. One such configuration of a computer-readable medium is signal bearing medium and thus is red to transmit the instructions (e.g., as a r wave) to the re of the computing device.
The computer-readable medium may also be configured as a computer-readable storage medium and thus is not a signal bearing medium. Examples of a computer-readable storage medium e a random access memory (RAM), read-only memory (ROM), an optical disc, flash memory, hard disk memory, and other memory devices that may use magnetic, optical, and other techniques to store ctions and other data. The storage type computer-readable media are explicitly defined herein to exclude propagated data signals.
WO 31475 An operating system 412 can be maintained as a er executable module with the computer-readable media 408 and executed on processor 406. Device executable modules can also include a beer production module 414 as described above and below.
Beer tion module 414 can be implemented to control various facets of beer production, such as described in process 300. For example, beer production module 414 can control dilution, fermentation, filtration, transfers of e and mixtures between vessels, ation, and cleaning. In various embodiments, beer production module 414 monitors carbon dioxide evolution and, upon detecting that a pre-determined amount of carbon dioxide has been released into the here, can shut off the gas valve effective to use additional carbon e generated to pre-carbonate the beer. In various embodiments, the beer is pre- carbonated to a level of 2.0 — 2.6 (volume/volume), and is measured by an input device 402, such as a pressure transducer.
In addition to measuring carbon dioxide evolution, beer production module 414 ' is configured to monitor alcohol formation and a drop in the c gravity of the mixture.
For example, given static state conditions of volume and temperature, beer production module 414 can monitor the alcohol formation and specific gravity drop h evolution of carbon dioxide. When the appropriate alcohol t has been reached, beer production module 414 can cause the ferrnenter to be cooled and arrest further fermentation. In various embodiments, beer production module 414 causes the ferrnenter to be cooled when the specific gravity of the beer is about 1.045 kg/m3.
Beer production module 414 can also be configured to cause a beer brewing system, including fermenters, transfer lines, filtration equipment, and bright tanks, to be cleaned. For example, in addition to being connected to each of these components via communication interface 404, system 400 can be connected to a clean water tank in which cleaning solutions can be made. Beer tion module 414 can direct a cleaning solution to be transferred to one or more specific components, implement and time a cleaning regime, and cause the component to be sanitized.
System 400 also includes an audio and/or video input/output 418 that es audio and/or video data to an audio rendering and/or display system 420. The audio ing and/or display system 420 can be implemented as integrated component(s) of the example system 400, and can include any components that process, display, and/or otherwise render audio, video, and image data.
