Talking Wine – June 2017
You may well have read a most interesting article in The Times recently concerning the fact that flavour perception when tasting wine is created in the brain. Our sensory response to food and wine combine to create what we think of as flavour in things that do not inherently possess it. Gordon Shepherd, a professor of neuroscience at Yale, says “the molecules in wine don’t have taste or flavour but when they stimulate our brains, the brain creates the flavour the same way it creates colour”. He goes on to explain that nosing a wine is less important than swilling it around the mouth but that swallowing the wine just causes more confusion. This saturates the brain and makes it harder to process information. We are heavily dependent on our own memories and emotions when analysing wine as well as additional factors like the composition of our saliva as well as age and gender. All very complicated but perhaps us wine tasters have got it right. Sniff, swill but don’t swallow. I know a few novice wine merchants who don’t always get that right!
