Homebrewers & Home Maltsters

The amateur layer. And in this category that word means something unusual. Gluten-free brewing has no industrial R&D department, so the people running the experiments are largely the people brewing at home. This page maps who they are and where they gather.

Every other role on this site has an institution behind it. This one does not: the homebrew layer is a field of individuals, clubs, forums, and one dedicated supply trade, and it produces a disproportionate share of the category's actual experimentation. The practitioner knowledge itself — the malting guides, the literature, the gaps — lives in the research directory; this page carries the people.

How to read it — entry rules, and what a listing means

Public work only. An entry requires a public-facing platform, body of work, or commercial offering: a club, book, maintained resource, or published body of process work. Private hobbyists are never listed, however good their brewing, without consent. Nobody is listed for hobby activity alone.

Two kinds of entry. Where the research directory already describes someone, this page carries a pointer. Where it does not, this page carries the entry, and for this role that is most of them: the homebrew layer is exactly the part of the field the subject axis cannot hold.

Described, never endorsed. A listing is a map reference, not a recommendation.

The roster — public-facing practitioners

Robert Keifer — author of Gluten-Free Brewing: Techniques, Processes, and Ingredients for Crafting Flavorful Beer (Brewers Publications, 2022), the category's book from craft brewing's own publisher. Per the publisher's bio: a homebrewer who learned the craft because the shelves had nothing for him, a Zero Tolerance club member, and co-founder of a dedicated gluten-free brewery, the homebrewer-to-professional path in one person. Also pointed at from brewers and writers & educators. The book, at the publisher · Verified 2026-08-25

Andrew Lavery — author of the most complete home-malting guide we have found: five stages (steeping, germination, kilning, cleaning, roasting) with temperature tables and grain-by-grain procedures, from a practitioner who, by his own account in the tutorial, has malted and brewed sorghum, millet, maize, rice, and buckwheat, and whose millet beer has placed in competition.

Bodies & gatherings — where this role actually meets

Zero Tolerance Gluten Free Homebrew Club. The first gluten-free homebrew club we have found, covered by the American Homebrewers Association as a first of its kind: founded in Portland, Oregon (January 2018 per the AHA's account), with members far beyond it, and a working definition that matches this site's own standard — "beer made with only gluten-free ingredients," explicitly excluding enzyme-treated barley beer. The club maintains a public wiki, including a community enzyme reference with products, dose ranges, temperatures, and pH windows, linked back to members' own experimental threads.

Competitions with gluten-free categories — the working list, with entry guidance, is on our competitions page.

Working with them — what a reader does with this role

If you brew gluten-free at home, these are your rooms: the club and guild for people, the forum for the searchable record, and this site's homebrew section for the standard mash, four documented methods, and recipes published as research.

If you want to malt at home, the practitioner knowledge (the Lavery tutorial, the magazine techniques pieces, the working method threads) is collected on the practitioner wing, and the acceptance and safety gates are in our malting section.

If you have numbers, that is what this field is shortest on. The research asks are written so any kettle can run them.

Where to buy — the dedicated homebrew supply layer is on suppliers.

How this role connects — the relationships, with receipts

The pro-am bridge runs both directions. The club's founding meetings were hosted at a working production brewery (per the AHA's coverage), and the category's book was written by a club homebrewer who went on to co-found a brewery (per the publisher's bio): in this field the amateur and professional layers are one community.
The club's definition is this site's definition: "beer made with only gluten-free ingredients," enzyme-treated barley out — arrived at independently by the practitioners and by our own standard.
This role feeds two professional ones. Homebrewers appear on brewers, home maltsters on maltsters; this page owns the amateur layer of both.
The category's most useful single number is held by this role, not by a laboratory. The club's published figures put barley malt at 418 °WK against malted sorghum's 54 °WK, roughly an eighth. That one comparison is why this role buys enzymes at all, and it sits on a practitioner wiki rather than in a textbook. The figures, indexed · the enzymes wing
A grain this role treats as filler is not enzymatically inert. The same reference lists rice malt at 231 °WK, more than four times malted sorghum, while the flavor work indexes rice as the deliberately characterless grain. Neutral in flavor turns out not to mean inert in enzymes, and nobody appears to be using it that way. Rice · flavor and sensory
The home maltster's thermostat reaches the finished beer's aroma. Heriot-Watt measured germination temperature against proteolysis in sorghum and millet; proteolysis sets free amino nitrogen, and free amino nitrogen is the ester precursor this directory identifies as the category's aroma bottleneck. A lever maltsters operate at production scale sits, at home, on a controller dial. The germination finding · the aroma gap
Practice and laboratory reached the same germination advice and cite each other never. The craft press tells home maltsters that millet and buckwheat want warmer, shorter germination than barley; researchers measured the same direction and published numbers. Two communities, one finding, no shared citation. Both, indexed together
The safety literature this role most needs is the literature it does not cite. Surveys of fungi, aflatoxins, fumonisin B1 and zearalenone in sorghum-based traditional malt, wort and beer exist, and the home-malting guides reference none of them. We have found no mycotoxin measurement taken from a home malting batch at all. This is a role-to-role gap between practitioners and researchers, not a gap in the science. The safety layer, indexed
The dedicated competition categories are closed to this role. The Great American Beer Festival's gluten-free categories require entrants to be licensed commercial breweries, so brewers generate scored feedback against gluten-free peers while homebrewers are judged against descriptors written for other grains. The largest population of gluten-free brewers produces the least comparable sensory data. Our competitions page
This role has no funder. Gluten-free malting and brewing research is funded, and the awards we have found went to universities. We have found no grant awarded to a homebrewer or home maltster for work at their own scale. The practitioner layer stays self-funded while the academic layer does not, and the two produce different evidence: many uncontrolled batches on one side, controlled studies on a few grains on the other. The funding record · research asks
A retailer is doing an institution's job. The tutorials, the hosted malting guide, the recipe library and the community measurement layer are all published by a shop, which is what happens to a field with no institution to carry its record. That makes suppliers a publishing relationship here, not only a purchasing one. What it publishes
Equipment, not knowledge, is this role's real barrier. The mash asks for tight temperature control, continuous movement, comfortable operation at 190°F and above, controlled cooling, and a runoff path for a huskless grist. The methods are written down; the rig decides who can run them. Equipment for the process · process and equipment
The grain mill is where this role meets the certifiers' problem. A mill that has crushed barley holds flour in its rollers, threads and body, and it is the first thing gluten-free grain touches; a home gluten test on a fermented beer is weaker evidence than it looks. What a lab can settle and what a kitchen can settle are different questions, which is why labs & certifiers is a role this one depends on. Shared equipment and cross-contact
This field's written record is authored by its practitioners. The book, the malting tutorial and the published millet parameters were all written by people who brew or malt at home, which is why writers & educators and this page share names rather than dividing them.

Who's missing — where this role's map runs out

Home malting has no organized community. The knowledge exists (tutorials, magazine pieces, working forum threads), but there is no home-malting club, no curated collection, and no shared quality or safety baseline. That gap, and the written record behind it, is documented on the practitioner wing.
Most of this field is unlisted by design. The public-work rule means the great majority of gluten-free homebrewers, including the best of them, do not appear here. That is the rule working, not a failure of the map.
We have found no second gluten-free homebrew club. One club, one guild grown out of it, and one forum section is the whole organized layer we have located: no regional chapters, no clubs outside the United States, and no gluten-free section inside a general homebrew club that publishes as one. If they exist, we have not found them.
The published process record is three sources deep. One practitioner publishing germination and kilning parameters, one hosted malting tutorial with per-grain procedures, and one club wiki carrying comparative diastatic-power figures and enzyme doses. Everything else we have found is thread discussion, and the wiki's headline comparison carries no published measurement series behind it. For a role whose claim on this directory is that it runs the experiments, that is a thin shelf. The count, on the practitioner wing
The roster's composition reflects public sources, not the field. Everyone listed is a US-based man, which is what we have found published, not who is doing the work. Corrections welcome.
