Champagne Bubbles Key to Taste
Let's raise a toast to champagne. And its ubiquitous bubbles. Because new research says the bubbles aren't just tickling your tongue. They're erupting with aromas vital to the taste of the beverage.
A team of （who else） French researchers used mass spectrometry to nose around a glass of champagne. They found that concentrations of certain molecular compounds were higher at the surface of the glass than in the liquid itself. They report the finding in the Proceedings of the National Academy of Sciences.
The scientists say the sea shares champagne's secret. If you've ever enjoyed ocean air, it's because compounds called surfactants are dragged along with bubbles in the waves. When those bubbles burst, the surfactants break into smaller molecules called aerosols that are suspended in the breeze, giving coastal areas their distinctive oceany odor. In essence, a glass of champagne hosts a small version of this process, but the bubbles bring more appetizing aerosols to the surface.
Legend has it that Dom Perignon shouted "I'm tasting the stars" when he uncorked his first bottle of champagne. But it was physics and chemistry, not astronomy, that he was really savoring.
破解香檳之謎：關(guān)鍵是泡沫
讓我們?yōu)橄銠壐杀瑸樗鼰o處不在的泡沫干杯。因為新的研究認(rèn)為，香檳的泡沫不僅僅刺激你的舌頭，它們還帶有大量的香味，這些香味對香檳的味道至關(guān)重要。
法國的一個研究小組（還能有誰呢？譯注：法國人以產(chǎn)香檳而自豪，也最喜歡研究香檳）使用質(zhì)譜的方法檢測了一杯香檳。他們發(fā)現(xiàn)，某些分子化合物的濃度在酒杯上面要比液體香檳本身含量高。研究者們在《美國國家科學(xué)院院刊》（Proceedings of the National Academy of Sciences）雜志上報道了他們的研究發(fā)現(xiàn)。
科學(xué)家們說，大海分享了香檳的秘密。如果你曾經(jīng)享受過海邊的空氣，那么你就能理解其中的道理了。這是因為在波浪中稱為表明活性劑的化合物附著在泡沫上。當(dāng)這些泡沫破滅的時候，這些表面活性劑分解為更小的氣溶膠分子，它們懸浮在微風(fēng)中，因此使得海岸地帶具有特殊的海洋氣味。從本質(zhì)上說，一杯香檳酒也表現(xiàn)出上述這樣的過程，只是規(guī)模小一些而已， 不過香檳泡沫把更多氣溶膠帶到了酒表面，從而讓你食欲大開。
據(jù)說當(dāng)Dom Perignon打開他的第一瓶香檳的時候，他大聲叫道："我正在品嘗星星".不過他真正品嘗的不是天文學(xué)，而是物理和化學(xué)。
