证明
a scale for measuring the strength of alcoholic beverages
Proof refers to a unit of measurement indicating the alcoholic strength of a beverage, particularly distilled spirits like whiskey, vodka, rum, and gin. In the United States, proof is defined as twice the percentage of alcohol by volume (ABV). For example, a beverage with 40% ABV would be considered 80 proof. Historically, the term "proof" originated in the United Kingdom, where it showed the alcohol content of spirits in relation to the amount of gunpowder that could still catch fire when soaked in the spirit. Today, it serves as a standard measure of alcohol strength, with 100 proof being typical for many spirits.
- In the United States, proof is a measure of the alcohol content in beverages, with 1 proof equal to 0.5% alcohol by volume.
在美国，proof是衡量饮料中酒精含量的单位，1 proof等于体积的0.5%酒精。
- The term "proof" originates from the British Royal Navy, where sailors would test rum strength by igniting it with gunpowder; if it burned, it was "proof" it contained enough alcohol.
术语「酒精度」源自英国皇家海军，水手们会用火药点燃朗姆酒来测试其强度；如果燃烧，那就是含有足够酒精的「酒精度」。
- A beverage that is 100 proof contains 50% alcohol by volume, while a 80 proof beverage contains 40% alcohol by volume.
100标准酒精度的饮料含有50%的酒精体积，而80标准酒精度的饮料含有40%的酒精体积。
- Bartenders and consumers often use the term "proof" informally to refer to the strength or potency of alcoholic drinks.
调酒师和消费者经常非正式地使用“酒精度”一词来指代酒精饮料的强度或效力。
- The term "proof" originated from a test where gunpowder soaked in alcohol would still ignite if the spirit was sufficiently strong.
术语“证明”源于一个测试，浸泡在酒精中的火药如果精神足够强大，仍然会点燃。
