为什么 纯生 或 干啤 英文对应的都是draft?

Draft Beer 或者 pure Draft Beer。（也可以叫draught Beer，这也是为什么我们也翻译做干啤的原因）。

细心的朋友会在青岛纯生上看到QingDao Draft Beer ，其实这也是比较正式的表达。

其实这个draft和纯生，都能表达这个啤酒的特征或者做法的不同。为什么叫“纯生”，我们可以从上面这段红字中了解到，就是“生”和“熟”的区别，有没有经过高温杀菌。而draft则表达了这个纯生啤酒怎么做的。我们可以看看下面这段英文，看看你看到什么动词。

Draught beer (also known as draft beer or tap beer) has several related though slightly different understandings. The majority of references to draught beer are of filtered beer that has been served from a pressurised container, such as a keg or a widget can[citation needed]. A narrower meaning is beer that is served from a keg (or tap), but not from a can, bottle or cask, is also used. A more traditional definition is beer that is served from a large container, which could be either a keg or a cask. The different understandings may at times overlap and cause confusion. Some traditionalists object to the more modern use of the word when applied to canned beer. The slight usage differences of the term is due to the history and development of beer dispensing.

Draught beer is usually unpasteurised in America.[citation needed] It is intended to be kept refrigerated between 2°C (35°F) and 4°C (40°F), and consumed quickly after being "tapped". Above 6°C (44°F), a beer may within two days turn sour and cloudy. Below 6°C (44°F), a keg of draft beer should last 20-30 days before it loses its fresh taste and aroma.

In the UK, the term keg beer would imply the beer is pasteurised, in contrast to unpasturised cask beer. Some of the newer microbreweries may offer a nitro keg stout which is filtered but not pasteurised, but the older established breweries do pasteurise.

One of Australia"s most popular beers is Carlton Draught, which is available on tap as well as in both cans and bottles without widgets.

Different beers also require different equipment for dispensing. For a detailed listing of brands and their respective keg taps and couplers, please see the Beer Brand / Keg Taps Couplers Listing.

draft英语中有拉拽的意思，名词有草稿，草纸，草案的意思。作为动词，有点反映这个draft beer的制作过程，因为它采用无菌膜过滤技术滤除酵母菌而不是加热的方法，就像是draft，拉拽，把啤酒和酵母菌分开一样。

作为名词，草稿，草案，就是比较初级的，好像是纯天然的，这就是说名draft beer 没经过高温加热，更能保留更多的原汁原味。
