Japanese scientists have developed a camera that confirms what we've long sensed: "wine glass shape has a very sophisticated functional design for tasting and enjoying wine." That's what Kohji Mitsubayashi, a researcher at the Tokyo Medical and Dental University, told Chemistry World.
It's a little complicated, and I'd encourage you to read this Chemistry World article, but the upshot is this: Mitsubayashi’s team used a special camera to analyze "different wines, in different glasses – including different shaped wine glasses, a martini glass and a straight glass – at different temperatures." And they found that "different glass shapes and temperatures can bring out completely different bouquets and finishes from the same wine."
In the video above, you can see the new-fangled camera in action, demonstrating how wines at different temperatures (something that's affected by the geometry of the glass) release different vapors. And those translate into different flavors. Get more on this at Chemistry World.
