FOR those who yearn for a well-aged, full-bodied vintage wine but lack the funds to feed the habit, the solution may lie with a Japanese boffin, a zany-looking contraption, a couple of metres of latex tubing and a few hundred volts of electricity.

Squirrelled away in his chemical engineering laboratory in rural Shizuoka, Hiroshi Tanaka has spent 15 years developing an electrolysis device that simulates, he claims, the effect of ageing in wines. In 15 seconds it can transform the cheapest, youngest plonks into fine old draughts as fruit flavours are enhanced and rough edges are mellowed, he says.
