Past couple days I have tried a different blend proportion to reduce the sweetness of Original and really found a nice balanced drink:
2 parts UU to 1 part Original (grammage depends on if your mixing one or two drinks)
For liquids – I replaced 30% of the water with fresh coconut water.
Really pleasant drink that doesn’t need any other flavours adding - the coconut water really smoothes off the UU and you really get the sense of the oaty back taste too.
