Long-time readers will probably remember the interesting interchange I had with Dr Patrick Farrell MW, after I posted on his magnetic wine ageing device (see here and for more comments here, although take less notice of some of the anonymous comments which could have come from anywhere).
It seems that the demand for wine ageing gadgets that operate outside the known laws of science has not yet been sated.
Take a look at Le Clef du Vin. One second = one year. Read for yourself! However, unlike Farrell's device, it doesn't claim to actually replicate the ageing of the wine. Instead, it reveals the ageing potential of the wine. How does it work? I don't think it can. Wine ageing is complex and poorly understood, and sticking a device in a glass for a limited period is unlikely to reveal too much information about its future trajectory.
Looking at the pictures of this gadget, and reading between the lines of the promotional blurb, I reckon this is a piece of copper mounted in a stainless steel support. The copper will address any reduction present, shifting the wine's redox potential towards the oxidation end of the spectrum. Ageing of wine is not simply oxidation.
The Advertising Standards Agency have this to say about claims made on behalf of this device.
