Yo,
My cola of choice was Coca-Cola, before they reformulated it back around 1985. Fond memories of drinking the old Coke while munching a bag of Lay's potato chips.
In the early days, they used to use real sugar, which gave it a better flavor... not sure how to describe it... sort of like it had a sharper, crisper taste... more of a bite.
After the backlash over the new Coke, they brought back "coke classic" and eventually the new Coke was phased out.
Some say that you can get the old Coca-Cola by buying the Coca-Cola from Mexico and I have, it's not the same.
