the root beer flavour spectrum

PREAMBLE: The Root Beer Flavour Spectrum is an experiment conducted by myself between december 28th 2005 and january 9th 2006 to determine the exact range of flavours contained in the numerous brands of root beer; it also features a breakdown of 'root beer' as a concept (discovery, primary ingredients, evolution) and a cursory exploration into the history of this beverage. ideally this will help clear up any confusions regarding the vast array of choices available to the root beer connoisseur. as far as i can tell, this is the very first experiment of this kind. altho i have not actually really researched this for fear that i may be wrong. don't anybody tell me about any other testings either. don't burst my bubble, dude.

BRANDS TESTED (so far):
Muggs
A&W
Pop Shoppe (contains phosphoric acid!)
Stewart's
Stewart's Diet
Hires
Jones'
Barq's

PREMISE:
I believe that (modern day) root beer exists on a flavour spectrum with Crush Cream Soda on one end, and Dr. Pepper on the other. All root beers contain varying ratios of these two flavours and so I've created the root beer flavour spectrum to reflect these polarities.
