Which beverage promotes itself as the “king of beers"?
In the 1860s, German immigrant Adolphus Busch arrived in the United States and began working at his father-in-law's brewery. Eventually, the company grew to launch Budweiser, the first nationally distributed beer, which was primarily sold bottled. That led to the brand's advertising tagline, "King of Bottled Beer." As its offerings grew and other draft and canned competitors rose up, it shortened the slogan to "King of Beers," which remains today.
