PARIS:
One of Britain's spinning top rare vino merchants and nuclear scientists in France have
jointly unveiled a 21st-century tool for unmasking counterfeit time of origin
wines.
The technique consists
of zapping bottles with ion beams generated by a particle accelerator. The beams
are directed at the spyglass, not the wine, and can severalise how old the bottles
are and, roughly, where they
start.
"We compare the
suspect bottles with those that we know come from the chateaux," explained Herve
Guegan, a researcher at the National Centre for Scientific Research (CNRS) in
Bordeaux.
"The chemical
composing of glass used to make bottles changed over time and was different
from place to plaza," he aforesaid.
To forbid counterfeiters from
filling veritable old bottles with ordinary plonk, Williams intends to combine
the ion beam test with another established method that checks for levels of a
radioactive isotope, cs 137, in the wine-coloured
itself.
This technique,
however, is simply effective in identifying wines made in the epoch of heavy atomic
weapons testing in the by and by half of the 20th
century.
The ion irradiation
technology depends on comparison with actual
bottles.
While the new test tush
verify the age of the bottleful, it cannot guarantee the quality of the
wine-colored.
Other technologies
developed in the last few age to fighting fine vino fraud include water simon Marks
and holograms on labels-much like those used on bank notes - on with bAR
codes and UV-sensitive markings.
