An invention for infusing liquids, such as beer or wine, at a desired temperature and pressure is disclosed. The invention comprises a fillable container to contain the infusing material and the liquid to be infused, a cooling system to maintain the temperature of the liquid at a desired level during infusion, and a pressurization system to facilitate dispensing the liquid after infusion.

This document relates to food products containing highly conjugated heterocyclic rings complexed to an iron ion and one or more flavor precursors, and using such food products to modulate the flavor and/or aroma profile of other foods. The food products described herein can be prepared in various ways and can be formulated to be free of animal products.

To provide an unfermented beer-taste beverage provided with fermentation flavor, and a method for producing the unfermented beer-taste beverage.

An unfermented beer-taste beverage provided with good fermentation flavor characteristic of beer can be provided by a method for producing an unfermented beer-taste beverage comprising a step of adding a flavor composition containing a sulfur-containing compound to an unfermented beer-taste beverage to achieve a content of the sulfur-containing compound of 1×10.sup.2 ppt or more but 1×10.sup.3 ppt or less.

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.

A method for preparing beer or cider concentrate including alcohol and volatile components of beer or cider flavor, and beer or cider prepared therefrom. The method includes a two step concentration method in which the first step involves a high efficiency nanofiltration that results in a highly concentrated retentate and an aqueous permeate fraction comprising alcohol and volatile flavor components. The second step involves removing water from said permeate fraction to obtain a highly concentrated alcohol solution also having volatile flavor components. The highly concentrated alcohol solution is then combined with the retentate from the first step into a final high alcohol and flavor beer or cider concentrate.

The present invention describes methods and devices in which concentrated beverage products, each packaged in a pressurized container, can be combined with liquids and/or other ingredients to produce one or more servings of a beverage. These products provide users with a convenient way to prepare both alcoholic and non-alcoholic beverages (including carbonated beverages) in various serving sizes and quantities by combining the pressurized beverage concentrate with (possibly carbonated) liquids and other ingredients.

A method for metering hops pellets into a fermented beer precursor in order to produce beer using a system having a metering system and a pump. Hops pellets are supplied into the system. A specified quantity of hops pellets are metered from the metering system to the pump. The specified quantity of hops pellets is supplied into a beer precursor-conducting line or a tank filled with beer precursor by the pump. The metered hops pellets are supplied into the beer precursor-conducting line or into the tank filled with the beer precursor in a pelleted and/or granulated form.

The invention relates to a fermented beverage as well as a method of producing a fermented beverage, particularly a beer or beer-like beverage, with an ethanol content of between 0.0% and 1.0% by volume, the method comprising providing an ethanol containing fermented base beverage, reducing the ethanol content of the fermented base beverage by a de-alcoholisation step, followed by adding flavor to the fermented base beverage with reduced ethanol content to produce the fermented beverage, wherein the added flavor includes at least an amount of 4-vinyl guaiacol (4VG).

A compound represented by the following formula (1): ##STR00001## wherein, R.sub.1 is a linear or branched alkyl group having 1 to 3 carbon atoms or a hydroxyl group; and R.sub.2 is a 1-pyrrolyl group, a 2-pyrrolyl group, or a 3-pyrrolyl group. The present invention can provide a means highly effective in contributing to savory roasting flavor and capable of imparting fragrance with natural feeling.
