No point pretending you like your mate's home-brew! Facial expressions reveal our beer preferences

For years, beer drinkers have had to pretend to enjoy dodgy-tasting beer served up by hipster breweries and enthusiastic home-brewers. Now researchers in Japan say two different facial expressions can truly reveal whether or not we enjoyed a beer immediately after trying it. In experiments, the scientists used facial recognition technology to scan people's facial expressions to reveal their true beer preferences. 'Lip suck', where the lips are drawn inwards as if we're saying'mmmmm', indicate that we enjoy a beverage, the experts claim. Conversely, 'lip press', where the lips are pressed down on top of each other, reveals that we actually thought a beer tasted horrible.
