Vanilla COAs are full of numbers that look meaningful but are easy to misread. This short guide walks through every field you will encounter — moisture content, vanillin percentage, microbial counts, heavy metals, pesticide residues, and origin declarations — and tells you what acceptable ranges look like, what red flags to watch for, and which numbers suppliers sometimes fudge.
Includes a one-page COA quick-reference checklist you can use on every future purchase.
