Hi there, we're sorry to hear you didn't enjoy the taste or mixing experience. In case you would like to give the product another go, please make sure to follow the instructions on the back of the package, as it's really important for this product.
If you tried mixing it into milk directly, it doesn't work. It needs to be whisked into a splash of off-the-boil water and then topped up with milk. Adding a bit of liquid sweetener to the powder and water also helps. Lastly, make sure not to put too much powder because it can taste bitter.
Detailed instructions can also be found on Blume's website (scroll to the bottom): https://itsblume.com/products/matcha-coconut-blend
Hope this helps and you get to enjoy your matcha!
