From the nuclear tests in the desert of New Mexico to the Fukushima disaster, every year, artificial radioactivity is being uniformly deposited all over the planet. In most cases, these radioactive particles have no effect on our health. This anthropogenic singularity is mostly, and very scientifically, used to date a vintage without extracting it. It’s a technique often used at auction where fine wines are “qualified” before being shown.
It’s a non-destructive and reliable anti-fraud procedure, but it only works for vines that were growing after 18 July 1945, the date of “Trinity”, the first recorded nuclear test.
