As an experienced sommelier and brewer, I can certainly shed light on the difference between draft and draw beer. These terms refer to the way in which beer is served, particularly in regards to the method of dispensing it from a container.
First, let's discuss draft beer. In the United States, the term “draft” is more commonly used, while in the United Kingdom, “draught” is the preferred spelling. However, the pronunciation remains the same. Draft beer refers to beer that is served from a keg or cask, typically stored in a refrigerated system. The beer is pushed out of the keg using carbon dioxide (CO2) pressure, which propels the beer through a tap and into a glass or mug. This method allows for a consistent flow of beer and often results in a frothy head.
On the other hand, “draw beer” is a term that is less commonly used but can still be found in certain regions or establishments. Similar to draft beer, draw beer is also served from a keg or cask. However, the key difference lies in the method of dispensing. Rather than using CO2 pressure, draw beer is pulled from the keg using a hand-operated pump known as a “beer engine.” This device creates a vacuum that draws the beer up from the container and into the glass.
One significant distinction between draft and draw beer is the level of carbonation. Draft beer, being dispensed under CO2 pressure, tends to have a higher level of carbonation compared to draw beer. This results in a livelier and more effervescent experience when consuming draft beer. Draw beer, on the other hand, is typically less carbonated, offering a smoother and more mellow drinking experience.
Another aspect to consider is the serving temperature. Draft beer is usually served at a colder temperature due to the refrigeration system it is stored in. This chilled temperature enhances the refreshing qualities of the beer and helps to maintain its freshness. Draw beer, on the other hand, is often served at a slightly warmer temperature since it is not typically stored in a refrigerated system. This can allow for more complex flavors to emerge as the beer warms up slightly.
In terms of personal experiences, I recall visiting a traditional pub in the UK where they exclusively served draw beer using beer engines. The experience was quite unique as the bartender skillfully operated the pump, pulling the beer into the glass with precision. The draw beer had a smooth and velvety texture, with subtle flavors that developed as I savored each sip. It was a more traditional and authentic way of enjoying beer, which added to the overall charm of the establishment.
To summarize, the main difference between draft and draw beer lies in the method of dispensing. Draft beer is served under CO2 pressure, resulting in higher carbonation levels and a colder serving temperature. Draw beer, on the other hand, is pulled from the keg using a beer engine, leading to lower carbonation levels and a slightly warmer serving temperature. Both methods offer unique experiences and can contribute to the overall enjoyment of the beer.
