The premise is wrong. Who CAN’T taste the difference between the two? Pepsi tastes like crap and I don’t really give a damn about their histories.
Yep; Pepsi tastes like crap, and Coke tastes like kerosene.
I drink (when I can find it) Royal Crown/RC-Cola; I use Coke for mixing with rum; and buy Pepsi to serve to some friends who inexplicably won’t drink anything else.
Now, now, that’s not quite true.
I’m not a Papsi fan, and the problem with Pepsi is the use if pepsin as a flavoring agent.
See Pepsodent toothpaste and Beeman’s chewing gum.
Either you like the flavor of pepsin or you don’t. I don’t care for it and can’t get past it in Pepsi.
