Nuclear Bombs Expose Fake Wines

Here are two seemingly unrelated facts. One: from the late 1940s through 1963, we tested atomic bombs in the atmosphere. Two: wine lovers are sometimes duped into spending exorbitant amounts for fake vintage bottles that weren't from the year they were supposedly grown.

這里有兩件看上去毫無關(guān)聯(lián)的事。一，從20世紀(jì)40年代晚期至1963年，我們在大氣中測試了原子彈。二，酒類愛好者們經(jīng)常被騙，買了大量生產(chǎn)年份造假的酒。

But Graham Jones at Australia's University of Adelaide thought he could use bomb information against counterfeit wines. [He talked about his research at the meeting of the American Chemical Society in San Francisco.] Carbon dating works by comparing the amount of carbon 14, which is a less common and less stable form of carbon, to the more abundant carbon 12.

可澳大利亞阿德雷德大學(xué)的格雷漢姆·瓊斯認(rèn)為他可以用原子彈來打擊假酒。（他在舊金山舉辦的美國化學(xué)協(xié)會(huì)會(huì)議上談到了自己的研究。）碳紀(jì)年是通過比較碳十四（碳的一種較不常見、不穩(wěn)定的形式）與數(shù)量更多的碳十二的量進(jìn)行測定的。

For thousands of years, the ratio between the two has been the same. But those two decades of atomic bomb tests increased the C-14 in the atmosphere. And as growing grapes absorb carbon dioxide, they take in trace amounts of the heavier carbon isotope—which eventually show up in the wine.

幾千年來這兩種物質(zhì)的數(shù)量都是一樣的，可人類進(jìn)行原子彈測試的二十年大氣中碳十四的含量增加了。生長中的葡萄會(huì)吸收二氧化碳，也就會(huì)吸收微量質(zhì)量更重的碳同位素，這種吸收最終會(huì)在酒中表現(xiàn)出來。

The research team checked C-14 levels in 20 Australian red wines with vintages from 1958 to 1997. They compared the wine's C-14 to C-14 in atmospheric samples from the same years. And found a direct match—C-14 levels could give away the vintage year for each wine.

研究小組測定了二十瓶澳大利亞紅酒的碳十四含量，其生產(chǎn)日期為從1958至1997年不等。他們將酒中的碳十四含量與生產(chǎn)年份大氣樣品中的含量進(jìn)行比較，發(fā)現(xiàn)兩者有著直接聯(lián)系——碳十四含量完全可以透露每瓶酒的年份。

So beware wine scammers. Because even at the atomic level, in vino veritas.

所以造假酒的人注意了哦，即使是原子也會(huì)酒后吐真言的。
