Champagne. Do you drink it out of a narrow flute or the broader, more shallow coupe?
你喝香檳時(shí)用細(xì)長(zhǎng)玻璃杯還是廣口淺杯？
You may have noticed that your perception of the bubbly wine changed as gas escaped from it, and new research finds that the concentration of gas depends on the glass.
也許你已體會(huì)到，當(dāng)盯著香檳氣泡從杯中流溢時(shí)，你的視覺享受也會(huì)隨之變化。一項(xiàng)新研究發(fā)現(xiàn)，香檳氣泡的濃度取決于酒杯的形狀。
French researchers, but of course, monitored the concentration of ethanol and carbon dioxide in each type of glass for 15 minutes after champagne was poured. They discovered that there was a much higher concentration of carbon dioxide in the tall flute than the broad coupe.
法國(guó)研究人員做了一項(xiàng)實(shí)驗(yàn)：將香檳傾入形狀各不相同的酒杯中，然后對(duì)杯中乙醇和二氧化碳的濃度進(jìn)行15分鐘的監(jiān)測(cè)。他們發(fā)現(xiàn)，細(xì)長(zhǎng)酒杯中香檳的二氧化碳濃度要比廣口淺杯中香檳的二氧化碳濃度高出很多。
Infrared imaging of the glasses gave a visual confirmation. Although the glass shape did not affect the concentration of ethanol vapor, the temperature did, with chilled champagne releasing less ethanol, but the same amount of carbon dioxide. The work is in the journal Public Library of Science ONE.
對(duì)酒杯進(jìn)行的紅外成像檢測(cè)更直觀地印證了這一研究結(jié)果。雖然酒杯的形狀并不影響乙醇蒸氣的濃度，但對(duì)于釋放少量乙醇的冰鎮(zhèn)香檳而言，酒杯形狀卻能對(duì)相同數(shù)量的二氧化碳產(chǎn)生影響。這項(xiàng)研究成果刊登于《科學(xué)公共圖書館》雜志上。
Based on their findings, the researchers were able to construct a model for how carbon dioxide moves from liquid to gas. And for champagne drinkers, the finding may help them choose the perfect glass. Cheers.
基于這一發(fā)現(xiàn)，研究人員就能建立一個(gè)模型以模擬二氧化碳從液體轉(zhuǎn)化為氣體的過程。而對(duì)于香檳愛好者而言，這一發(fā)現(xiàn)可以幫助他們選擇合適的酒杯。來，為這一成果，我們干一杯吧。
