Description

METHOD OF BREWING NONALCOHOLIC BEER

CROSS REFERENCE TO RELATED APPLICATION [0001] The present application claims the benefit of and priority, under 35 Ci.S.C. § 119(e), to U.S. Provisional Application Serial No. 62/933,035, filed November 8, 2019, entitled “Method of Brewing Non-Alcoholic Beer,” the entire disclosure of which is hereby incorporated herein by reference, in its entirety, for all that it teaches and for all purposes.

BACKGROUND

[0002] The present disclosure is generally directed to the brewing of malt beverages, and more particularly, to a method of brewing a nonalcoholic beer wherein fermenting is conducted with a low percentage of high krausening wort within a water brew containing hops.

[0003] The natural process of brewing beer involves the creation of alcohol within the beverage. Alcohol is a desirable characteristic of beer, however within recent times, a market has developed for nonalcoholic beers. The term “nonalcoholic beer” refers to a brewed malt-based beverage containing 0.5% or lower ethyl alcohol by volume.

[0004] The alcohol in beer is produced by fermenting wort with yeast. Wort is a solution produced by mashing grains, typically ground-up barley malt, with or without additional fermentable ingredients such as corn or rice. The solution is prepared in a large quantity of hot water in which the barley malt and other adjuncts are mashed to extract sugars and other soluble substances such as low molecular proteins and polysaccharides. Hops are added to the wort as it is boiled to provide the desired bitterness that is a characteristic flavor component of beer.

[0005] In traditional brewing processes, after the wort is prepared, it is pitched with yeast and allowed to ferment for several days until the yeast has consumed all or substantially all the fermentable extract in the wort. As the fermentation proceeds, most of the fermentable carbohydrates are converted by the yeast into ethyl alcohol and carbon dioxide. Other additives may be added to the wort order to enhance the flavor of the resultant beverage. After filtering and finishing, the resultant beverage is the desired beer. [0006] The flavor of beer may be considered as having three essential components: bitterness contributed by the hops, the flavor of the constituents from the barley malt that are not digested by the yeast in fermentation, and aroma components that are fermentation byproducts contributed by the yeast. Most of the known brewing process for nonalcoholic beer compromise or alter at least one of the flavor components because the processes either substitute or hinder normal brewing processes as compared to brewing regular beer. [0007] Despite what may seem as a relatively simple process for brewing beer, the chemical processes that take place to create a distinctive malt-based beverage, and one that may be repeated with high quality and consistency, require significant production controls. Even the slightest variations in components and processing will result in a brewed beverage that has its own unique characteristics, and which may differ from the desired product.

[0008] There are numerous methods of producing nonalcoholic beer, but most suffer from significant drawbacks. One well known method is to complete the brewing process and then attempt to remove the ethyl alcohol to reduce the alcohol content to at or below the 0.5% threshold. Alcohol removal, from an equipment and labor standpoint, is extremely expensive. Further, because the beer is typically heated to boil off or evaporate the alcohol, this additional heating has a degrading effect on the taste of the beer wherein the delicate balance of beer constituents are disrupted.

[0009] Another well-known method is to arrest the fermentation process, or to use substitute microbials which do not produce ethyl alcohol or produce low levels of alcohol during fermentation. Disrupting or modifying fermentation will result in significantly different flavors that are produced as compared to the traditional brewing process in which the full lifecycle of yeast during fermentation adds necessary flavor and body to the brew. This method also tends to leave behind significant quantities of undesirable unfermented extract.

[0010] Another known method of producing nonalcoholic beer is through cold contact brewing. Generally, cold contact brewing involves pitching wort with a yeast slurry and then fermenting the pitched wort at a relatively cool temperature (such as about 5°C) for a monitored period of time. The cooler temperature during brewing slows down reproduction of the yeast and therefore, reduces alcohol content as compared to a traditional fermentation in which the pitched wort is allowed to ferment at a much higher temperature. This method, like arrested fermentation, also tends to leave behind significant quantities of undesirable unfermented extract.

[0011] One example of a prior art reference which discloses a process for preparing a nonalcoholic malt beverage is disclosed in the U.S. Patent No. 4,970,082. This reference discloses four basic process steps for preparing the beverage: (1) producing a wort having a high extract concentration that includes fermentable sugars (concentration of between 14 - 20%) (2) obtaining a yeast slurry from a previous ordinary beer fermentation in which the slurry contains 10 - 20% yeast solids and the remainder beer: (3) pitching the wort with the yeast slurry; and (4) fermenting the pitched wort for 30 min. to 10 hours at about 3°C - 7°C, resulting in a beverage having an alcoholic concentration of about 1% to 2%. The concentration is subsequently reduced to less than 0.5% by dilution of carbonated water. This method also results in significant quantities of remaining unfermented extract.

BRIEF SUMMARY

[0012] Despite the plethora of references that may disclose various methods for producing a nonalcoholic beer, there is still a need for a method in which the resultant beverage has a superior flavor and one which is clearly identifiable as a quality beer despite the reduced alcohol content. There is also a need for a method in which the process itself is relatively simple and repeatable, thereby minimizing cost and reducing production controls.

[0013] In view of the foregoing, it is one object of the present disclosure to provide a method of producing a nonalcoholic beverage having a true, distinctive beer flavor. It is yet another object of the present disclosure to produce the nonalcoholic beverage with a flavor that departs from many existing nonalcoholic beers which may be generally categorized as being over-sweet and/or excessively “worty” in taste.

[0014] A method of the present disclosure begins with producing a “hop tea” or “water brew.” First, water is heated within a bulk container such as a kettle. Additions are added to the water including components such as salts and acids. For example, mineral salts and lactic acid may be added to bring the water brew to a pH of between about 4.0 to 4.5.

These salts and acids may serve several functions to not only balance the pH of the solution, but to also add electrolytes and to otherwise condition the water in preparation for subsequent brewing.

[0015] The water brew is brought to a boil and then hops may be added. Both bittering hops and aroma/flavoring hops may be added in which the bitterness of the water brew is brought up to between about 20 to 40 International Bitterness Units (IBUs).

[0016] Next, the water brew is cooled to about 10°C and placed in a fermenter. The cooled water brew is then pitched with 10-15% high krausening wort. This fermenting wort is chosen when at the high krausen stage or point; which means that fermenting times can vary, but a typical range is between about 20-36 hours after the fermenter is fully loaded and there is full yeast activity, i.e., the high krausen stage is peaking.

[0017] High krausening fermenting wort is chosen because test trials indicate this early stage of fermentation provides yeast cells in a preferred stage of cell development that create a wide range of flavors having beer-like properties that are captured within the water brew solution. Specifically, more aromatic flavors are captured when high krausening wort is selected. Contrast selection of high krausening wort to later stages of fermentation in which many flavor compounds are lost or “scrubbed out” of the solution as carbon dioxide continues to be produced in the fermentation cycle. Further, choosing fermenting wort prior to the high krausen stage develops undesirable flavors. One visual indication of the high krausen stage is the highest or greatest yeast foam being produced. Accordingly, adding fermenting wort prior to the water brew prior to formation of the maximum foam or after the foam begins to collapse, does not provide the same high soluble levels of desirable flavors being retained in the liquid solution to contribute to final base characteristics.

[0018] The high krausen stage is measurable through assessment of YIS (yeast in suspension) Yeast cell counts increase due to cell replication from the point of fermenter filling when yeast is pitched to the wort and cell counts are at 16 million cells/ml. The YIS counts top out at the high krausen stage with around 70 million cells. As the yeast foam collapses after the high krausen state, the YIS counts quickly decrease as well. Regular YIS testing can be used when the high krausen stage occurs without requiring visual confirmation.

[0019] The 10-15% amount of high krausening wort combined with the water brew is enough to achieve about a 1% ABV in which the fermentation is permitted to proceed to completion. Accordingly, the fermentation is not arrested as in many other methods of brewing. Because of the relatively small amount of krausening wort that is added to the water brew, fermentation in the present method does not achieve the much higher ABV values found in regular beer fermentation processes, yet the flavor benefits of a complete fermentation cycle is maintained since fermentation is not arrested. The yeast are allowed to proceed through their normal life cycle and produce fermentation flavors akin to what they produce in a normal alcoholic fermentation cycle.

[0020] After fermentation is completed, the product is diluted by a factor of 2 with carbonated water or a deaerated brewing liquor to reduce the ABV to just below 0.5%. [0021] More preferably, the fermentation is completed to an end attenuation of approximately 0.95% ABV and the dilution brings the product to approximately 0.42% ABV.

[0022] The product at this stage can be referred to as the “base.” From a taste perspective, the base is a very clean, dry, and light carbonated beverage with an easily recognizable beer flavor, but without some finished beer qualities such as those that round out the body and aroma in an alcoholic beer.

[0023] Flavoring may be added to the base to include flavoring agents such as malt extracts, selected individual flavorings, aroma components and corn sweeteners. Corn sweeteners and malt extract add body or viscosity to the base. It is also contemplated that other flavors may be added to include new flavors which provide a taste sensation of alcohol.

[0024] Considering the above described features and attributes, in one aspect, embodiments of the present disclosure may comprise a method of brewing a nonalcoholic beer comprising: heating water within the container; adding selected components to the water including at least one salt or at least one acid; bringing the water to a boil; adding selected hops to create a water brew; cooling the water brew; adding a selected percentage of a high krausening wort to the cooled water brew; fermenting the wort to complete the fermentation cycle to produce a base product; diluting the base product; and adding at least one flavoring to the base product to produce the finished nonalcoholic beer.

[0025] There are numerous benefits to the method of the present disclosure described herein. First, for example, the controlled fermentation cycle avoids a requirement to remove alcohol which, in existing alcohol removing processes, is extremely expensive because of the equipment required. Second, the controlled fermentation still enables completion of a full fermentation cycle thereby providing taste benefits relating to a distinctive beer flavor achieved in regular brewing processes. Further, the controlled fermentation may still use a selected brewer’s yeast as opposed to immobilized yeast or substitute microbials which may otherwise add considerable expense to the brewing process.

[0026] Additional features and advantages are described herein and will be apparent from the following Description and figure. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] Fig. 1 is a flow diagram depicting a method of brewing a nonalcoholic beer in accordance with embodiments of the present disclosure.

DETAILED DESCRIPTION

[0028] Embodiments of the present disclosure will be described in connection with a method of brewing nonalcoholic beer wherein fermenting is achieved with a high krausening wort added to a hop tea or water brew. The term “high krausening” as defined herein may refer to the phase of fermentation when the wort reaches the peak of the fermentation cycle, that is, the peak of the reproduction of the yeast. The high krausen stage is visually observable, and is characterized by a large billowing head of foam that forms on the surface of the fermenting beverage. When the reproduction of the yeast slows, the head of foam also subsides which provides another visual indication of the advancing krausening stages. The low krausen stage, may be visually characterized by a dense, cream-like and relatively uniform head of foam. The head of foam is white in color at first, but then carbon dioxide bubbles congregate particulates from the wort causing the foam to then develop yellowish brown colored tips.

[0029] In some embodiments, the method of brewing nonalcoholic beer is optimized with use of the high krausening wort because, among other things, transferring the high krausening wort to the water brew at this stage in the fermentation cycle results in the maximum flavor benefits.

[0030] Fig. 1 is a flow diagram depicting a method 100 of brewing a nonalcoholic beer in accordance with embodiments of the present disclosure. In one embodiment, the method 100 begins with the production of the hop tea or water brew in which water is heated within a bulk container (step 104). The water brew is conditioned to achieve a desired pH level and to otherwise condition the water in preparation for receiving the high krausening wort. For instance, at least one of salts and acids may be added to the water to balance the pH of the solution, to add electrolytes, among other reasons (step 108). One preferred range for the pH of the water brew is between about 4.0-4.5. In some embodiments, the water brew may be completely absent of yeast.

[0031] Next, the method 100 continues by bringing the water brew to a boil (step 112), and then selected hops may be added for flavoring (step 116). In some embodiments, bittering hops and/or aroma or flavoring hops may be added in which the water brew is brought to a selected bitterness. According to one embodiment, the bitterness of the water brew may be brought to a bitterness measurement of about 20 to 40 IBUs.

[0032] Other additions beyond a range of mineral salts, acids and hops are contemplated dependent upon the outcome desired for the base liquid. For example, in another embodiment, additions could further include a cold mash (cold brew) of malts and barleys (or alternatively oat) resulting in addition of beta-glucan soluble fibers. These fibers contribute a certain roundness of body to the mouthfeel due to the impact of the beta- glucan, which are complex carbohydrate gums to create a somewhat viscous solution at higher concentrations.

[0033] A next step in the method 100 is to cool the water brew to approximately 10°C and place the water brew in a fermenter (step 120). At this point, the water brew is pitched with 10-15% of high krausening wort obtained from another fermenting vessel (step 124). Stated another way, the high krausening wort may be pitched at 10% to 15% of the water brew volume. As mentioned, the high krausening wort is obtained by visual inspection; however, other means may be incorporated to retrieve the high krausening wort at a desired fermentation point. In some embodiments, the high krausening wort may be added to the cooled water brew without boiling the high krausening wort.

[0034] The high krausening wort and water brew are allowed to ferment for approximately 5 to 7 days which is adequate time to enable fermentation to proceed to completion (step 128). Accordingly, the fermentation is not arrested and all the flavor benefits achieved with the completed fermentation cycle are obtained. Contrast completed fermentation of the present disclosure as compared to arrested fermentation that halts the yeast in mid-life-cycle, typically prior to the cells completing their normal replication cycles. Arrested fermentation has disadvantages displayed in a range of undesirable flavors commonly described as worty, raw grain, sulfury, yeasty or green beer flavors. Further, arrested fermentation often leaves behind a high level of unfermented constituents that make for a quite sweet liquid that is not normal (typical) for light lager beers.

[0035] After fermentation is completed, the product is diluted by a factor of 2 with the carbonated water or the deaerated brewing liquor to reduce the ABV to a desired percentage, such as below 0.5%, and more preferably to approximately 0.42% ABV (step 132).

[0036] Although pitching the water brew with the 10-15% of the high krausening wort is selected in accordance with one embodiment of the present disclosure, it is also contemplated that other percentages of the high krausening wort may be selected resulting in different percentages of ABV being produced. The 10-15% range results in the ABV being approximately 1%, which is a convenient percentage for dilution by the factor of two to therefore bring the ABV to just below the 0.5% level.

[0037] The resultant base product may be further conditioned to receive desired flavoring agents to include malt extracts, selected individual flavoring components, and corn sweeteners (step 136). Malt extract and corn sweeteners add body or viscosity to the base, and may be used to sweeten the product as well. Special other flavors may be added, such as a flavor which may provide a taste sensation of alcohol.

[0038] The methods described herein provide many advantages over existing methods for brewing nonalcoholic beer. The controlled fermentation cycle avoids requirements to remove alcohol which add significant costs because of required equipment. The controlled yet completed fermentation cycle provides superior taste benefits corresponding to the distinctive beer flavors achieved in regular brewing processes. The controlled fermentation still enables a selected brewer’s yeast as opposed to immobilized yeast or substitute microbials which may add considerable expense to the brewing process and may degrade the flavor of the end product.
