[Ed. – Who needs humans?]
Robots might be unseating the cherry job of wine critics soon. Researchers in Denmark have created an artificial tongue to find out whether expensive wine actually tastes any better than the cheap stuff.
The research, first published in ACS Nano, claims that an optical nanosensor based on surface plasmon resonance (SPR) can discern how you experience the sensation of dryness in wine. And they say this nanosensor can judge the way the tannins will hit your flavor sensors better than the finest wine critic can.
Some may argue that it takes a human, not a robot, to discover what is worth a sip. However, the researchers at Arhaus University argue that the nanosensor is free from the human critic’s personal prejudice. They may have a point. There’s a lot that goes into making wine taste a certain way. Everything from the variety of the grape to the minerals in the soil to what kind of sunlight the grapes received chemically affects the taste and smell of the wine from season to season – in even the same grape.
