Dublin Dr Pepper no longer exists. A few years ago, the now-defunct pop was made with the original formula including Imperial Pure Cane Sugar and not high fructose corn syrup used in most Dr Pepper. When I had the pictured bottle, the only cane sugar-version of Dr Pepper was produced in Dublin, Texas at the world’s oldest Dr Pepper bottling plant, built in 1891 just six years after the soda pop’s creation in nearby Waco. (Dr Pepper was invented one year before Coca Cola.)
The artwork on the neck of this type of Dr Pepper has the 10-2-4 numbers in different spots than the traditional logo.
In the early 20th Century, researchers believed that sugar could provide a needed energy boost during the times that an average person experienced a letdown during the day at 10:30 AM and 2:30 and 4:30 PM. A contest was held to create a new slogan with the winner being, “Drink a bite to eat at 10, 2, and 4.”
As an additional bit of trivia, note the absence of a period after “Dr”. It was discarded as part of the name in the 1950s.
The bottling plant in Dublin lost their exclusive license in 2012 for selling their Dr Pepper to broader markets than they were supposed to. (I bought this bottle in Ohio.) A different plant is now authorized by the main company, the Dr Pepper Snapple Group, to produce sugar-sweetened Dr Pepper but it no longer bears the name of any particular town.
