Finding a Contract Craft Maltster

The Craft Maltsters Guild publishes a directory of member malthouses. It is a good way to find maltsters. It is not a way to find gluten-free maltsters — membership is a trade credential, not an allergen credential, and assuming otherwise is the mistake this page exists to prevent.

Craft Malt Finder — Map-based directory of member malthouses. This is the one you want. Membership is not a gluten-free indicator.

Craft Maltsters Guild — Trade association for small-batch independent malthouses; also runs a craft malt certification program.

Guild contact page — General enquiries. They do not broker contracts; approach malthouses directly.

The reader this is for​

"I have grain, or I want gluten-free malt made to a spec, and I do not own a malthouse."

That middle path — paying a craft malthouse to run your grain — is barely written about anywhere. Most malting content assumes you are either buying finished malt or malting at home.

What the Guild is​

A trade association for small-batch, independent malthouses (also seen as the North American Craft Maltsters Guild). It runs a membership program and a craft malt certification program, and publishes the Craft Malt Finder.

For the job of finding out which craft malthouses exist and where, the Finder is the best single starting point available.

Right for you if you need a list of small maltsters who might take a contract run.

Not what you need if you expect the directory to filter for gluten-free. It does not, and no directory does. Nothing on the Guild's public site addresses gluten-free or allergen handling at all.

Our experience​

Tier: Directory.

We have not worked with the Guild and have not evaluated any member. We point you at the Finder because it is genuinely the best way to find maltsters — and then you do the qualifying yourself, which is what the rest of this page is for.

We are deliberately not endorsing the Guild or anyone in it. An endorsement is an authority claim, and our authority comes from commercial gluten-free brewing experience, not from auditing a trade association's membership. "Here is the directory, and here is what to ask" helps you more than a recommendation would, because it equips you to judge a maltster we have never heard of.

What to assume before you start​

Assume every member is a barley malthouse until they tell you otherwise in writing. That is not cynicism, it is the base rate. Craft malting is a barley industry; a malthouse that handles gluten-free grain properly is the exception and knows it.

Guild membership tells you nothing about whether a member handles gluten-free grain, runs dedicated equipment, or tests for gluten. Do not read it as a signal in either direction.

How to approach them / what to ask​

Find candidates in the Finder and contact them directly. Ask every maltster these, and get the answers in writing — the call builds the relationship, the email is what you keep in the batch record.

Will you run a non-barley grain at all? Start here. Many will not — sorghum, millet and rice behave differently through steep, germination and kiln, and a barley-optimized malthouse may simply decline. That is a fine answer and it saves everyone time.

Dedicated or shared? Do you run gluten-containing grain in this facility at all? On this equipment? If shared, what physically separates my lot — separate line, separate vessel, or the same kit on a different day?

Cleandown and changeover. What is your documented procedure between a barley run and mine? Who signs off? Can I see the SOP? Has the changeover been validated by testing, or is it a procedure someone believes works? See Cross-Contact Prevention.

Testing. Do you test finished malt for gluten? Which method, what threshold, every lot or periodically? Malt is a pre-fermentation input, so an assay can actually read it — this is where testing carries most weight. See Gluten Testing Methods and Their Limits, and Testing Without an In-House Lab if you end up arranging it yourself.

Documentation. Lot-level documentation and results with each delivery? What happens to my lot if a result comes back over threshold — who absorbs it, and do I get told?

Minimum lot size. Often the deal-breaker. Craft malthouses have a floor below which a custom run is not worth the changeover, frequently larger than a new brewery's first order.

Turnaround and scheduling. How far out are you booking, and where does a custom gluten-free run sit against the barley schedule?

Price for a small run — including the changeover cost, where a gluten-free run gets expensive and where a quote can hide.

Reading the answers​

A maltster who answers these easily, in writing, with documents attached, has been asked before. That fact alone is informative.

Hesitation on the documentation question is the answer to the documentation question. So is a verbal assurance offered in place of an SOP. You are not being difficult — you are doing the supplier qualification that the claim on your label eventually rests on.

If you need a malthouse that already runs gluten-free​

The Finder will not tell you which members those are. Malthouses That Run Gluten-Free covers the two we know of and, more usefully, how to verify any of them.

Verified as of 4 August 2026 — read the Guild's public site and located the Craft Malt Finder. Confirmed nothing on their public site addresses gluten-free or allergen handling. We have not contacted the Guild or any member.

Gluten Free Brewer has no commercial relationship with the organizations on this page and receives nothing for listing them. If that ever changes, it will be disclosed here.
