QA Trust Chain
One lot. One accountable chain.
A finished beer is trustworthy only when every custodian can prove what it accepted, what it did, what it handed forward, and why the lot was released.
Follow the lot from source to release
Grain Source and Acceptance
Qualify the source, identify the exact lot, sample it representatively, and decide whether it may enter the truly gluten-free chain.
Open gate and record →Grain and Malt Storage
Keep accepted grain and released malt identified, segregated, suitable, and protected from cross-contact and condition loss.
Open gate and record →Malting and Malt Release
Connect accepted grain to a controlled malt batch and release the finished malt only for a named next use.
Open gate and record →Brewery Receiving and Production
Accept released malt on boundary evidence, protect the brewery path, and establish the gluten-free basis before fermentation.
Open gate and record →Packaging and Finished-Beer Release
Reconcile the beer, package, label, verification, upstream chain, deviations, and final disposition before release.
Open gate and record →Safe Transport and Custody
Test before shipment, verify carrier fitness, seal and document custody, then test or explicitly accept the risk at receipt.
The chain is complete only when all evidence agrees

What a representative sample and suitable method establish against a predefined criterion.
What records prove about custody, genealogy, deviations, disposition, and authority.
Throwing a lot out permanently removes it from the released truly gluten-free chain. It may not be retained for dilution, blended into a passing lot, or resold as usable gluten-free material. Document its final destruction or lawful outside-chain disposition.
The chain implements the Truly Gluten-Free standard and supports the trust decisions described for the information-seeking gluten-free buyer.
Why Pre-Fermentation Evidence Is the Gatekeeper
Fermentation breaks proteins into smaller fragments. FDA says current tests do not adequately detect and quantify gluten in fermented and hydrolyzed foods, so applicable gluten-free claims rely on records showing that the food met the definition before fermentation, that cross-contact was evaluated, and that preventive measures were implemented.
That produces the controlling GFB rule:
No pre-fermentation proof, no gluten-free release.
Finished-beer testing still matters. It is additional verification and a way to catch an unexpected failure. It cannot reconstruct missing supplier, transport, intake, equipment-path, ingredient, or pre-fermentation evidence.
The GFB “No Detected Gluten” Standard
GFB recommends no gluten detected by a suitable method. The laboratory report must identify the sample, matrix, method, laboratory, and reporting limit.
Do not treat <10 ppm as the definition of “not detected.” It is a common quantification limit for
one competitive R5 method used with fermented matrices including beer; other methods and matrices
can quantify lower. For example, that method lists an approximately 4.6 ppm gluten detection limit
and a 10 ppm quantification limit. The actual report controls the statement.

The Commercial Rule at Every Handoff
Test the lot before it leaves. Test it when it arrives—or sign acceptance of the shipment and the commercial risk. Record who controlled it in between.
Without boundary evidence, everyone can blame the last handoff and nobody can prove where contamination entered. GFB recommends written agreements assigning intake condition, sanitary responsibility, outtake condition, boundary sampling, investigation cost, and replacement/rush costs. Those commercial terms require qualified legal drafting; they are not automatic conclusions about legal damages.
Use Safe Transport and Custody whenever grain, malt, or finished product moves.
Experience and Limits
This system is adapted from commercial production QA planning developed through Bard's and carried forward as Gluten Free Brewer experience. The durable lesson is the connected chain—not an old company specification. Each facility must approve the specifications, hazards, methods, sampling frequencies, reporting limits, authorities, and legal requirements that apply to its product and operation.
