It’s just a difference in preference of taste @RyanT I believe.
A lot of (actually pretty much all) brands vary the ingredients and flavours of well known foods from country to country.
It’s partly to do with cost of ingredients and different legislations, but mainly due to varying preferences.
For example lots of well-known brands of drinks and snacks and ice lollies in Spain are less sweet than in the UK. And in America they are even more sweet.
Taste chocolate in five different countries and it will be very different.
I know Huel stated that the chocolate premix was popular in taste trials in the US but not liked so much in the UK. I can understand this - American chocolate (eg Hershie) tastes completely different to what we are used to over here.
Different cultures definitely have different tastes. You couldn’t really sell exactly the same flavours everywhere - you have to cater to the preferences and tastes of each country individually, to a certain extent.
Even in the UK though we can’t seem to agree on flavours what one person thinks is disgusting sweet and intensely flavoured, someone else finds not sweet enough and bland… go figure.
