Abstract: The process of improving the flavour and aroma of liquor is an invention intended to mellow liquor flavours and aromas—like those of matured ones—and eliminate undesirable odours resulting from poor manufacturing process. The crux of the invention lies in a material which has unique properties and steps taken which include mixture preparation, selective optimisation of particles in liquor, separation of undesirable particles and arrangement of particles in liquor by relying on flow velocity, temperature, and electromagnetic field in controlling collision of particles in liquor. The output is liquor with rather unaltered physical appearance, ester and alcohol content, not causing irritated throat, burning stomach or nausea which results from uneven alcohol content throughout liquor's body. Besides, this process overcomes limitations of existing liquor treatment techniques; it does not bring more heavy metal residues to the output liquor or cause particles in liquor to become more volatile.
