The invention relates to a vodka bottle which is preferably made of glass materials. The vodka bottle comprises an oval top portion. The invention comprises a metal band which is used for advertising and the user can also use the metal band as a wearable bracelet. The activated carbon balls inside the vodka bottle distill and purify the alcoholic beverage.

A method and device for efficiently removing an unwanted component included in a beverage, which includes bringing the beverage into contact with a metal-supported zeolite.

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.

An improved method of maturation of an unaged or partially aged distilled spirit, the method comprising: exposing the spirit to at least one catalytic material consisting of a group selected from: iron oxide nanoparticles, alumina-supported Fe(II) complexes, Pd/C, multiwalled carbon nanotubes, carbon xerogels, carbon based solid acid catalysts, SO.sub.4.sup.2-/TiO.sub.2/-Al.sub.2O.sub.3, an element selected from the group consisting of: columns 4-12 transition metals except for Fe, column 13 boron group, Si, and mixtures thereof; wherein throughout the exposing, the spirit is not being distilled, and the exposing is allowed until level of at least one maturation congener in the spirit attains predetermined desired congener level/s in the spirit.

A variety of potentially harmful substances can be removed from alcoholic and non-alcoholic beverages as well as condiments using a pack that includes a variety of ingredients within a liquid-permeable housing. The pack is immersed in a liquid that needs to be detoxified, with the ingredients binding to the potentially harmful compounds within the liquid, and after a desired period of time, the pack is separated from the liquid, thus removing from the potentially harmful compounds that are bound to the ingredients from the liquid. When combined within a single compartment of the housing, the ingredients display synergy in removing of many of the potentially harmful compounds. Additionally, the packs can be enhanced for removal of particular sets of compounds, such as environmental pollutants, illicit substances, mold and mycotoxins, food additives, and additional alcohol toxins.
