WOW I'm relieved to know I'm not the only one who sees the difference! I MUCH prefer the Coke in Spain to the stuff here. I just thought it was my 'I love Spain' attitude coming out again, but turns out my very sophisticated taste buds did catch a difference!!
I ALWAYS get a lemon in it now too, especially when I'm drinking the Diet Coke. (Coca Cola Lite is much better than Diet Coke is here, I'm assuming for the same reason...)
