My country's version of the Mountain Dew recipe actually is three separate sodas. And hell, one of the Brands had its own spinoff series through the 90s.
Goombay, Goombay (I dunno, one bottled in Capital Island and other in Freeport?) and Junkanoo.
They are named after the local summer festivals. One just happened last night.
So our version of Crystal Mountain Dew, for example, was named Junkanoo Tingum. Tingum is local slang a lot of islander people don't speak the "thhh" sound and Tingum is a catch all phrase.
But both plain Junkanoo and Goombay punch tastes just like Mountain Dew but with more cane sugar.
