 Cooking is one big science experiment. And chefs have been gaining fame for more explicit 1 use of scientific techniques and tools in the kitchen.


 
Now, according to an article in the December issue of Physics World, mixologists—the folks behind the bar—are getting into the act. They're borrowing tools from the labs to create wild new libations. 
 
Here's one example. Alcohol is better than water at delivering flavors and aromas 3, since many of those molecules 4 aren't water-soluble.
 
Plant material is fermented 5 and then heated to extract the alcohol that contains those flavors—that's distillation 6. But the heat can destroy some aroma 2 molecules.
 
Enter the scientists' rotary 7 evaporator. The fermented liquid goes in a rotating container. The pressure is lowered, so volatile 9 components 10 evaporate. Then a cool coil condenses the vapor 8 back into liquid.
 
One mixologist in London used this technique to make a mild habañero liqueur. The spicy 11 capsaicin isn't volatile—so it gets left behind. The final product has the fruity and floral flavors of chili 12 peppers with none of the searing heat.
 
For more proof, go to the article "Cocktail 13 Physics," at physicsworld.com
 
Thanks for the minute. For Scientific American's 60-Second Science, I'm Cynthia Graber.
