REPORT QUESTIONS
Understanding the Results.
Concise answers about Category I classification and the shipment covered by the certificate.
Does this report cover every future batch?
No. The certificate states that its result is limited to the referred sample. We use it as evidence for the tested 4 kg shipment, not as a guarantee that every future batch will return identical figures.
What does Category I mean?
Category I is the highest classification reported under ISO 3632. The certificate records this result for the tested sample across colour strength, flavour, aroma, moisture and physical purity.
