I thought the appended item from my physics listserv would be of interest to
AFWers. An article about the device also appears in today's web version of
Time Magazine.

ELECTRONIC WINE TASTING. Scientists in Spain have developed an
"electronic tongue" designed to distinguish a good Pinot Noir from a
cheap Chablis. The "e-tongue" is designed for wine quality control
in the field and is based on tiny synthetic membranes on a silicone
chip. The device, developed at the Barcelona Institute of
Microelectronics, can distinguish between four grape varieties and
its developers are working to extend its ability. Cecilia
Jimenez-Jorquera said the device is similar to the human tongue in
that it is sensitive to five different tastes: sweet, salty, bitter,
acidic and umami (savory). The e-tongue can determine the age and
variety of wine, and eventually might be able to "detect frauds
committed regarding the vintage year of the wine, or the grape
varieties used."
