Her Indoors and I often enjoy a bottle of wine (or 10) of an evening, but I openly admit that I don't know a good vintage from a £3.99 special at Tesco. However, a 60cm-tall wine sniffing robot has been invented that can distinguish good wine from bad. An object placed against a sensor on the robot's arm triggers an infra-red beam which is then analysed to reveal the object's chemical make-up. The robot then names the brand and describes the wine with comments such as, "a full-bodied shiraz". However, some would say simply reading the label is a cheaper and quicker alternative.
