I am not sure about the water angle...though yes tea and maybe Beer do taste different in different places.
I never had and problems with cordials or soft drinks until they started chuffing around with the recipes to allow for the reduction in sugar content....in my opinion, that is when the tastes changed.
I will not buy drinks that have chemical sweeteners in them.
I find it increasingly difficult to buy good quality cordials that have not been adulterated with these chemicals(I consider them to be poison and they do not reduce the risk of obesity one jot)
M&S in Blackburn stock NO fruit cordial that is not sugar free....the Preston Branch only have two varieties that are unadulterated.
