We recieved an update from wonder flavours as follows:-
Recommended mixing percentages updated.
Following the tremendous amount of great feedback we have received on our Super Concentrates, we have updated many of the recommended percentages. Most flavours now begin with a usage rate of 1% (or less). This should be your starting percentage in a standalone flavour test, if you find the particular flavour to be lacking, you can then increase towards the maximum usage rate.
