Provided herein are methods of making a hard seltzer beverage, wherein a base beverage is filtered using one or more filtration stages. In various embodiments, hard seltzer beverages that are produced using the methods provided herein may be substantially colorless; may have a substantially neutral taste; and/or may have a reduced carbohydrate content. In some embodiments, the methods provided herein enable the production of hard seltzer beverages having one or more of these advantages without significantly reducing the alcohol content of the beverage.

A method for producing an ethanol solution includes obtaining, from a starting liquid, a liquid feed having less than by weight of constituents and having 3% to 25% by weight of ethanol, supplying the liquid feed to a feed stream inlet of a reverse osmosis separation system having a first pass, wherein (i) each pass has an reverse osmosis membrane filtration unit, each membrane filtration unit having an ethanol rejection percentage of between 50% to 99%, and (ii) each pass has the feed stream inlet for a feed stream, a permeate stream outlet for a permeate stream, and a retentate stream outlet for a retentate stream, operating the system to maintain pressure in one of the membrane filtration units in a range of 1,200 to 4,000 psi, and obtaining retentate that is enriched with ethanol, the retentate differs from the starting liquid by absence of the removed constituents.

Methods of separating components traditionally considered as waste material from mold-fermented compositions are described. The waste components can be separated either from unfiltered compositions or from a separation stream separated from a composition. In some embodiments, filamentous fungus used in the production of the mold-fermented composition is specifically targeted for separation. Incorporation of separated waste components into various products are also described herein. In some embodiments, the separated components are used in alternative meat products and other foods designed for human consumption. Separated components can also be used in animal feed, as feed stock for other fermentation processes, or for use in treating food, creating cosmetics, or chemical processes.

Improved compositions of reversible monoamine oxidase inhibitors are obtained by improved methods of alcohol removal from distillates of fermented agave extracts.

A reverse osmosis filtration system includes a set of two or more reverse osmosis pressure vessels coupled in series, each pressure vessel having one or more reverse osmosis membrane elements, a feed inlet, a retentate outlet, a permeate outlet. The pressure vessels are coupled so that each successive pressure vessel has (a) its feed inlet coupled to the retentate outlet of its preceding pressure vessel and (b) its permeate outlet coupled to the permeate outlet of its preceding pressure vessel. The permeate outlet of at least one pressure vessel includes a front permeate outlet and the permeate outlet of at least one other pressure vessel includes a back permeate outlet. The back permeate outlet of one pressure vessel is coupled to the front permeate outlet of a successive pressure vessel.

Agave derived beverages with improved quality contain enhanced ratios of MAO B to MAO A inhibitors or enhanced concentration of inhibitor of MAO B.

A system and method are provided to produce a beverage concentrate such as a beer extract. A forward osmosis (FO) filtration technique removes pure water from a conventional brewed beer; accordingly, the beer extract can be produced without distillation or other alteration steps that may negatively impact of flavor and aroma components of the beer. A draw solution is used to provide a differential osmotic pressure through a FO filtration device. The diluted draw solution is recycled by reverse osmosis, distillation, and combinations thereof.
