Testing Without an In-House Lab
Quality assurance can read like it assumes a laboratory down the hall. It does not. The gluten-free trust chain was built on third-party testing: independent labs that sample grain, certify allergens, and analyze finished beer. Using them is normal, affordable, and often more credible than testing yourself, because the result comes from an outside party with no stake in the answer.
This page maps the network. Match the provider to the point in the trust chain where the result can still change a decision.
The network at a glance
| Provider | What it does | Where in the chain | How you engage it |
|---|---|---|---|
| FGIS (USDA Federal Grain Inspection Service) | Official grain sampling and grading — test weight, moisture, damage, foreign material, and mycotoxins through its labs | Grain intake (Gate 1) | They come to the grain and sample it the right way. Details → |
| State seed lab (North Dakota State Seed Lab) + FGIS | Germination and purity of the seed/grain lot — Bard's ran germination through both | Grain intake / seed qualification | Submit a drawn sample |
| FARRP (Food Allergy Research & Resource Program, University of Nebraska) | Allergen and gluten testing by ELISA; results reported against a 10 ppm limit of quantitation (5 ppm offered) — Bard's results were all non-detects | Grain and malt — pre-fermentation inputs | Ship a sample; receive a result and certificate |
| Malt-quality lab (e.g. Montana State University Barley, Malt & Brewing Quality Lab) | Malt analysis to ASBC methods: moisture, extract, colour, protein, FAN, enzymes. Montana State lists an adjunct malt analysis that names sorghum | Malt release (Gate 3) and trial lots | Discuss the sample with the lab first, then ship it. Details → |
| White Labs | Finished-beer analytical panel and microbiology — gravity, ABV, attenuation, color, pH, IBU, diacetyl, wild yeast, and bacteria | Packaged product (release) | Ship bottles; receive a full QC panel |
Retain a sample at every step. A test you can't repeat on a held sample is a test you can't defend.
The testing matrix
The table above is the labs. The matrix below is the chain: eight handoffs from the seed bag to the packaged beer, and at each one the test, who runs it, the method, who pays, and how a disagreement gets settled. A disputed malt result is settled by the written specification: a lot that meets it is bought, so the buyer writes the specification out in full before the run.
If the explorer does not load, open it directly at the testing matrix.
FGIS — official grain inspection
The first gate is grain, and FGIS is how a brewery or maltster gets official, independent sampling and grading without owning any of it. The sample is drawn to a standardized method, graded, and lab-tested, so the number at intake actually means something. Because the value is as much in how the sample is drawn as in the test itself, FGIS gets its own page.
FARRP — allergen and gluten testing
FARRP, at the University of Nebraska, is an allergen research and testing program that runs gluten ELISAs and reports each result with a certificate of analysis. It's a testing lab. The gluten-free certification programs, which do the certifying, accept its results as evidence. Its role in the chain is to verify the pre-fermentation inputs (grain and malt), where a gluten test can actually read the material (see Gluten Testing Methods and Their Limits). A FARRP result below the limit of quantitation (10 ppm on every report Bard's holds, with a 5 ppm option offered) is the kind of independent verification a serious gluten-free claim is built on. Engagement is simple: draw a representative sample, ship it, and keep the certificate with the lot's batch record.
Malt-quality labs — what the finished malt measures
A malt-quality lab tells you whether a lot of malt will do its job in the brewhouse: moisture, extract, colour, protein, FAN and enzyme activity, measured to ASBC methods. The lab that produced this site's founding malt numbers, Hartwick College's Center for Craft Food and Beverage, closed its malt-and-brewing laboratory on 1 April 2026; the labs directory records where former clients were pointed. Montana State University's Barley, Malt & Brewing Quality Lab publishes an adjunct malt analysis that names sorghum, millet, maize and rice.
One caution for a gluten-free program: Montana State runs that adjunct analysis in a mash with base barley malt. It gives you quality numbers, and it says nothing about gluten. Gluten status still comes from an allergen lab such as FARRP.
White labs — finished-beer QC
White Labs runs a full finished-beer panel: real and apparent extract, attenuation, ABV, color, pH, IBU, diacetyl, and a microbiology screen for wild yeast and bacteria. This is the analytical side of the packaged-product release test: it confirms the lot is sound and consistent. Note what it does not do: a finished-beer panel does not establish the gluten-free claim, because fermentation defeats the common gluten assay. That proof stays upstream.
The practical points
- Sampling beats testing. A perfect assay on a bad sample is a bad result. Draw representative samples; where an official method exists (FGIS), use it.
- Test where it still matters. Incoming input, cast wort and packaged product each catch a different failure. See Gluten Testing Methods and Their Limits.
- Costs are modest and they change. In Bard's era, having FGIS come out to sample ran about $35 per call, cited as a real-world reference point. Confirm current fees, turnaround, and availability directly with each provider.
- Keep the paperwork. COAs, certificates, and grade sheets are part of the pre-fermentation evidence the claim depends on. File them with the lot.
