In the classification of beer, draft beer is a beer that has not undergone instantaneous autoclavage at the time of delivery, so the nutrients and aroma of the beer are preserved to the greatest extent. Local breweries usually have many directly operated bars, and draft beer is not bottled, but delivered directly to consumers in the form of barrels. It is a real draft beer, and since it can be sold quickly, there is no need to worry about spoilage due to a short shelf life.
In order to allow consumers from afar to enjoy draft beer, some breweries do not have pasteurization, but they use cold filtration to filter out bacteria and other microorganisms before leaving the factory, and then bottle it, and the beer packaged in cans with nitrogen balloons can have the same soft taste as beer served directly from the bar. However, cold filtration still loses most of the yeast and hop particles, resulting in a loss of flavor.
The stout of this method can also be called a dry stout, which refers to the type of stout that tastes relatively refreshing, is not thick and viscous, and does not have a high alcohol content. It is also tailored to meet the needs of modern people. It's a relatively good choice when you need to taste more and don't want to get dizzy with alcohol, and for audiophiles, it's a bit of a simplified version.
