The present invention is directed to a beer having reduced quantities of AcHFA. It has been found that beer with reduced AcHFA quantities has improved foam stability. The invention provides beer with reduced AcHFA quantities, as well as methods for removing AcHFA from beer during or after fermentation, or for removing a precursor for AcHFA from wort.

The present disclosure relates to methods and compositions for fining fermentable beverages, such as alcoholic fermentable beverages, for example, wine, beer, lager, ale, cider, perry, spirit and liqueur. The compositions herein comprise a pectin and carrageenan which are used to treat the beverage prior to fermentation.

Low-dusting, granular compositions are provided that comprise at least 15% by weight crosslinked polyvinylpyrrolidone.

The present disclosure relates to a compound, in particular it relates to a polymer that may be used in the field of protein removal from aqueous solutions, in particular from wines. Furthermore, the present disclosure also relates to a method of production of said compound and to uses thereof.

The invention relates generally to sorbents and sorption devices for extracting compounds. The invention relates to a sorbent comprising a polymer and microdiamond. The invention also relates to a sorption device comprising the sorbent. The invention further relates to methods of using the sorption device for extracting organic compounds from a fluid and for preparing a sample containing organic compounds for analysis.

This invention relates to the preparation and utility of proliferous polymer compositions comprising repeating units derived from (a) a monomer comprising at least one functionalized or unfunctionalized acryloyl moiety and at least one lactam moiety, (b) an optional monomer comprising at least one double bond, and (c) a at least one cross-linker.

Caffeine-adsorbing materials, caffeine-adsorbing systems, and decaffeination system suitable for removing caffeine from a solution; methods for removing caffeine from a solution; and methods of making the caffeine-adsorbing materials are described.

A method for reducing the concentration of smoke taint compounds in smoke tainted fermented fruit juice (e.g., wine) is described. The method can include removing volatile flavor and/or aroma compounds from the affected fermented fruit juice and then removing smoke taint compounds by contacting the affected fermented fruit juice with a resin that absorbs smoke taint compounds. After removal of the smoke taint compounds, the previously removed volatile flavor and/or aroma compounds are recombined with the remaining fermented fruit juice. Also described is an apparatus for reducing the concentration of smoke taint compounds in smoke tainted fermented fruit juice, as well as the reduced smoke taint fermented fruit juices themselves.

A method of producing beer having a tailored flavour profile is provided comprising the successive steps of: (a) fermenting wort containing fermentable sugars with yeast to produce beer containing 1-10 vol. % ethanol and flavour substances diacetyl; acetaldehyde; dimethyl sulfide; ethyl acetate; isoamyl acetate; ethyl valerate; ethyl hexanoate; iso-amyl alcohol and 2-methylbutan-1-ol; (b) contacting the fermenting wort or beer with porous adsorbent particles, selectively adsorbing the beer flavour esters ethyl acetate, ethyl hexanoate, ethyl valerate and isoamyl acetate; (c) separating the adsorbent particles; (d) desorbing a portion of the beer flavour esters from the adsorbent particles; and (e) adding a fraction of the desorbed beer flavour esters to the flavour adjusted beer or to another beer, wherein the amount of beer flavour esters added is 5-95 wt. % of the amount of beer flavour esters removed by the adsorbent particles.

Certain embodiments of the invention provide a method of preparing a modified distilled alcoholic spirit, comprising contacting a corresponding starting distilled alcoholic spirit with a base under conditions that cause at least one free carbonyl compound in the starting distilled alcoholic spirit to be reduced, to provide the modified distilled alcoholic spirit that has at an alcohol by volume (ABV) of at least 15%. Certain embodiments also provide a modified distilled alcoholic spirit prepared by the methods described herein.
