You Make the World Taste Better.

Dr Pepper really does make the world taste better!
And did you know that it was the first soda invented that is still on the market?
That's right, Dr Pepper was first introduced in 1885 by a German pharmacist named Charles Alderton in Waco, TX, and was introduced nationally in 1904. It is reportedly the combination of 23 different soda fountain flavors that were available at the time of its conception (essentially, a pre-mixed suicide for those of us who remember going to fast food places and mixing EVERYTHING at the fountain). It has NEVER contained prune juice, as legend suggests.
In some parts of the country Dr Pepper is enjoyed hot, and remember there is NO period after Dr in Dr Pepper.
