How to distinguish the age of Whiskey

How to distinguish the old whiskey? Has less radioactive particles May 6, 2009, by Haley A. Lovett The level of radioactive carbon in the whiskeys produced after 1950 is higher due to nuclear bomb experiments, facilitating the distinction of appearing to be old whiskey again. Radiocarbon dating helps to identify fake whiskey A bottle of whiskey pretending to be a Macallan Rare Reserve 1856, which would have sold for tens of thousands of dollars, had to be withdrawn from a Christie’s auction in December 2007 and was initially estimated that close to 1950. A striking feature revealed the real age of the malt: radioactive particles.

Researchers Radiocarbon Accelerator Unit Oxford can now determine if whiskey was manufactured before 1950 thanks in part to the number of nuclear experiments that were happening then. Organic material alive after the start of atomic testing contains more carbon remains radioactive organic material before the nuclear tests. The barley used to make whiskey is a natural material so that scientists can examine the remains of whiskey radiocarbon looking and determine the date of manufacture.

Most of the tests are performed for the Research Institute of Scotch, a science center that seeks to maintain the quality of the distilled spirit, improve and preserve the integrity manufacturing industry products like whiskey authenticating old.

Dr. Ton Higham, deputy director of the Radiocarbon Accelerator Unit of Oxford, says that most of the whiskey samples are sent out to be after 1950. Although radiocarbon dating has helped identify several fraud cases whiskey bottles supposedly ancient, cannot always determine the exact date of its creation. “If before 1950 can only say that we can not contain carbon pumps,” explained Dr. Higham. Background: Operation of radiocarbon dating with whiskey Carbon 14 is a radioactive particle that is found naturally in the atmosphere as carbon dioxide. Plants absorb carbon dioxide through photosynthesis and then consume the radiocarbon animals as they eat plants. Radiocarbon levels in plants or animals would then be the same as that found in the atmosphere during its life. After the plant or animal dies, the radiocarbon begins to decay, and the scientists used the ratio of radiocarbon and stable carbon present in the remains of the body as well as his knowledge of the rate at which the radiocarbon decays, to date remains.
