Keep moisture content low |
8. What does a moisture reading tell you? |
The average moisture content of a batch |
10. If the average moisture content is below the maximum permitted level, can you be sure of having prevented mould growth in the coffee? |
No, because if the drying was very non-uniform it is possible for individual beans to have enough moisture to support mould growth.

Yes |
