I’ve experienced the same taste decrease that is mentioned on the forum, although it seems to be only recent (order april 10th 2019). But it seems more has changed in the recent batch, than just the taste. It dissolves less well and it has lots of ‘seed like’ things in it, which make the last few sips really unpleasant.
I was surprised and doubted myself because there was no mention on the packaging or website about a formula change. The change seems to be across all the flavours. Is it really a formula change or just a mishap or something? Or did I just receive the old formula until april this year?
