I bought these for an American friend visiting England.
I tried once only, which for me was more than enough!
The vile sour acidity of the outer coating almost gave me cramp in my face muscles, but I guess that is what the whole point of Ultra sour is right!
the inner hard shell was actually quite pleasant with a refreshing lemon taste, that was only slightly sour and gave some relief from the initial onslaught of sour acidity.
Then came the inner fizz which not unpleasant was again fairly sour.
Overall it was a great experience that I shan't repeat; but glad I tried just for the hell of it!
My American friend commented that it was not the sourest he had had but it was plenty sour enough. He is now thoroughly enjoying them!
