Most mushroom coffees list “beta-glucans” or “polysaccharides” somewhere on the bag. The problem is that some tests count starch from the grain the mushroom was grown on, which makes the number look bigger than the mushroom part really is.
1. Check the method
Look for “Megazyme K-YBGL” or an equivalent enzymatic method that reports beta- and alpha-glucans separately. If only “polysaccharides” is listed, you can’t tell mushroom from filler.
“If a brand won’t show you the method, the number is decoration.”
2. Match the batch
A report from 2022 says nothing about the bag in your cupboard. Our QR takes you to the exact batch printed on your bag.
