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.
