A fruit wine aroma enhancement brewing technology using cutinase belongs to the technical field of fruit wine brewing. According to the present disclosure, in order to solve the problem that fruit wine prepared through an existing fruit wine fermentation technology is poor in quality such as aroma and taste, Muscat grapes or apples are adopted as raw materials, and after crushing, separating peel residue, performing peel residue heat treatment and enzyme treatment, mixing the treated peel residue and clear juice, adding auxiliary materials (potassium metabisulfite, pectinase and β-glucosidase), adjusting a sugar degree, inoculating a high-glycerol-field yeast and fermenting with temperature controlled, inoculating an active dry yeast and fermenting with the temperature controlled until fermentation is finished, separating and removing the peel residue, fining, filtering to remove residue, performing stabilizing treatment and performing filtration sterilization, dry grape wine or cider is obtained. The present disclosure can be used in large-scale production of dry fruit wine.

The present invention discloses a process for preparing a sparkling alcoholic beverage resulting from the maceration of hops and/or its derivatives in wine with the addition of wine concentrate, vegetable water and/or water, fruit or vegetable concentrate and/or sugar, in order to reduce the alcohol content of wine, and which is gasified by a second alcoholic fermentation and/or addition of carbon dioxide. Through this process a sparkling alcoholic beverage having between 5 and 15% alcohol, a sugar content between 0.1 and 200 g/L, with a total acidity between 4 and 8 g/L is obtained having hops aroma, flavor and bitterness combined with aromas inherent to wine.

A highly purified diatomite composition may include greater than or equal to 90% silica, from about 0.5% to about 5% of a calcium-containing compound, and less than or equal to about 2% total of aluminum-containing oxides and iron-containing oxides. A method of making a highly purified diatomite composition may include providing a diatomite comprising at least 5% of a calcium-containing compound, calcining the diatomite, and acid washing the calcined diatomite. The calcined, acid-washed diatomite may include less than or equal to about 1% total of extractable aluminum-containing oxides and iron-containing oxides, and less than or equal to about 5% of the calcium-containing compound. The acid washing may include an acid selected from the group consisting of sulfuric acid (H.sub.2SO.sub.4), hydrochloric acid (HCl), and nitric acid (HNO.sub.3). The method may not include a flotation step.

The present disclosure relates to methods for producing large scale nanostructured material comprising carbon nanotubes. Therefore, there is disclosed a method for making nanostructured materials comprising depositing carbon nanotubes onto at least one substrate via a deposition station, wherein depositing comprises transporting molecules to the substrate from a deposition fluid, such as liquid or gas. By using a substrate that is permeable to the carrier fluid, and allowing the carrier fluid to flow through the substrate by differential pressure filtration, a nanostructured material can be formed on the substrate, which may be removed, or may act as a part of the final component.

The invention relates to a bottled sparkling white wine and to the method for producing same. The bottled wine contains a measured amount of an opacifying agent that does not alter the organoleptic properties of the wine; said measured amount, added prior to final corking of the bottle, consists of a suspension of finely divided oenological activated carbon in a food-grade liquid.

Pouring spouts used to filter bottled liquids as they are poured from a bottle containing such liquids.

A method of producing beer comprises the steps of producing or supplying a beer intermediate, wherein the beer intermediate is manufactured through a brewing process, storing the beer intermediate in a container, transporting the container containing the beer intermediate to a processing station where the beer intermediate is discharged from the container for further processing and mixing CO with the discharged beer intermediate. Before the step of storing the beer intermediate at least one of alcohol, malt syrup, wheat syrup, hop and sugar is added to the beer intermediate such that the stored beer intermediate forms a beer concentrate, wherein removal of water from the beer intermediate after the brewing process is omitted. Water is mixed with the discharged beer concentrate so as to obtain ready-to-consume beer or a ready-to-consume beer-like beverage. The produced or supplied beer intermediate has a CO2 concentration which is lower than 3 g/kg.

A system and method of the purification of drinking water, ethanol and alcohol beverages is based on the action of hydrodynamic cavitation processing of microbiological and chemical contaminants, micro particles and colloidal particles. The fluid flow moves at a high rate through a multi-stage cavitation device and filtration module to generate hydrodynamic cavitation features in the fluid flow. The cavitation features generate changes in the velocity, pressure, temperature, chemical composition and physical properties of the liquid. The cavitation features also prevent the deposition of contaminants upon and remove contaminants from the surface of the filter module, reduce the load on the filter elements and increase the life of the filter module.

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.

This disclosure includes regenerated inorganic fermented beverage stabilization and/or clarification media and a process for such regeneration. Inorganic stabilization and clarification media (for processing beer or the like) may include expanded perlite or other expanded natural glasses, diatomaceous earth, silica gel or other precipitated silicas and compositions that incorporate these materials. Such media may be regenerated individually, together in a mixture or together as part of a composite product. The regenerated media meet the requirements for physical and chemical properties for re-use and replacement of the majority of particulate inorganic filtration media and inorganic stabilization media consumed in stabilization and clarification processes, and the related regeneration process provides for substantial benefits to brewers through a reduction of costs to purchase and transport stabilization and clarification media, to dispose of spent cake and/or membrane retentate, while providing for substantial reductions in the introduction of soluble impurities into the fermented beverage.
