Final answer:
The best selling draft beer varies per establishment but globally, popular drafts include Bud Light, Coors Light, and Heineken, all of which are light lagers known for their crisp and refreshing taste.
Step-by-step explanation:
Since the question seems to be from the perspective of a bar or restaurant, identifying the best selling draft beer would vary depending on the establishment's sales data. Typically, a bartender or manager would have access to this information based on inventory turnover and sales reports.
However, without specific data, it's difficult to provide an accurate answer. If we consider popular draft beers globally, beers like Bud Light, Coors Light, and Heineken often top the sales charts. These beers are usually categorized as light lagers or pale lagers and are known for their crisp and refreshing taste. A beer similar to these bestsellers would be any light lager that offers a clean, easy-drinking experience with a mild hop and malt character.
