Draft beer is raw beer, which, unlike bottled or canned beer, has not been filtered, heated and sterilized. As a result, it retains a large amount of yeast and colonies, giving the beer a rich flavor and texture. Draft beer is also more natural and is actually beer in its most original form. People like draft beer because it allows them to feel the essence and charm of beer.

Draft beer has its own culture and history in many countries. For example, in Germany, draft beer is also called "Heimisch", which means "local". This is because each region of Germany has its own brand of beer and flavor, as well as its own brewing methods and standards. Draft beer has become a representative of the flavors of each region, and many breweries focus on its production and development.

Draft beer, because it is untreated, is easily spoiled or contaminated by microorganisms. Therefore, special care and handling is required when brewing, storing and consuming draft beer. Some breweries will add some preservatives to the draft beer to extend the shelf life of the beer. But this treatment will affect the taste and quality of draft beer. So, if you want to enjoy the flavor and characteristics of draft beer, it is better to choose fresh, draft beer without preservatives.
