This is Scientific American's 60-Second Science. I am Adam Hintertheur, got a minute?

These days it seems no one's job is safe from computerized replacement, now it is time to add coffee expertise to that list.

Scientists at the Nestle Research Center in Switzerland have developed a coffee testing machine that can sip and evaluate brume almost as well as professional human testers.

The machine takes a sample of the gases produced by a steaming shot of / espresso and analyzes dozens of ions associate with test and aroma , those ions are scient categories in a sensatory evaluation data set, but that doesn't mean the result are dried chemical formulas, in fact the machine has a vocabulary that will make any Samoyed blink.gif jealous.

After it crunches the number it splits out / words like floury,woody and butter toffee to describe its drinking experience. Researchers say machines like this could be / efficient monitors of quality control in the food industry and no matter how many cups of a day samples /, the mechanized coffee tester will never get jittery. Never the less room has it that the machine has already demanded a daily 15 minute anything but / coffee break.

Thanks for the minute, for Scientific American's 60-Second Science
I am Adam Hintertheur.
