Cocacola and Pepsico are competitors from early 30s.
In India Pepsi came almost 20 years before coke like in year 55 and coke in like 70s.
Pepsi black is like 15 tea-spoons of sugar in cola flavoured Soda-water but they say its calory free and max taste.
On the other hand, when it comes to Diet Coke its like 1/2 tea-spoon of sugar also, Coke energises and reduces your thrist to a greater extent and also reduces your hunger.
I am drinking Pepsi Black at very moment.
regreting.its very sweet.
I drank Diet coke yesterday and still remember that taste of cabonated water with a pinch of sugar.
