Questions, answered
How long does one pouch last?
About 6 days for a 300g pouch at 50g a day. The 200g brown rice pouch lasts about 4 days.
How do I drink it?
Mix 1 part concentrate with 1–2 parts water or your favourite drink. Also great in smoothies or as a natural sweetener.
Is there alcohol or added sugar?
No. The sweetness comes from koji fermentation.
Why is my pouch darker than the photo?
We ferment longer for more sweetness. Rice sugars and amino acids darken naturally. Quality is the same.
