There are certain advantages to being an old fart. I've been drinking legally since I was 18, for one thing. And I was lucky enough to have owned a 1970 Mustang Mach I which was still new enough not to have needed restoration and which I purchased from the original owner for $1000. I had a lot of fun in that car. And I remember what soda pop tasted like in the days before high fructose corn syrup took the place of sugar as the primary beverage sweetener.
That's why when PepsiCo releases limited-edition "throwback" sodas, I always try to buy a few cases. Like the recent limited-edition 125th-anniversary formulation of Dr. Pepper, made with real sugar as it's creator Charles Alderton intended.
There is such an amazing difference between sugar-sweetened and HFCS-sweetened Dr. Pepper that one can hardly believe that it's supposed to be the "same" drink. Gone is the overpowering, cloying sweetness of the corn syrup; instead the complex flavor profile of Dr. Pepper shines through and you can actually taste the root-beer-like base, vanilla notes, and stone fruit elements. I realize that it's a little ridiculous to be describing a soft drink as though it were being served at a wine tasting, but there ya go. This product is true Dr. Pepper. The corn syrup version is an imitation.
If you're too young to have had real Dr. Pepper from yesteryear, you should at least pick up a single can at a convenience store and try it out. Even better, buy a can of both the Throwback and today's standard Pepper and taste them side by side. I think you'll be astonished as well.
