Rice Research Directory

Who is working on rice as a brewing grain, and where the work lives. The rice page in our grain research directories: institutions, researchers, active projects, funders, industry players, organizations, and literature, mapped with the same rules — brief, factual, dated entries, every one linking to a primary source.

Rice holds a position neither sorghum nor millet can claim: the world's most studied cereal, a century of history inside American lager as an adjunct, the only gluten-free grain with a peer-reviewed base-malt cost model, and a working dedicated malthouse — yet rice as a serious gluten-free base malt is younger science than either of the other grains. Proven ingredient, rich infrastructure, emerging craft.

Coverage is US-centered by design. This site works in the American supply chain, with international anchors included where the science is foundational.

The rules every directory runs on, what an entry is, what a listing means, and who owns a person, are on one page: How the directories work. Corrections and removals: contact us.

5. Industry & Supply Chain — where rice is the most normalized gluten-free grain in brewing19 entries

Rice's commercial position is unique: it has been inside American beer at the largest scale for over a century — as the classic adjunct in American lager, and it has a dedicated gluten-free malthouse built around it as a single grain, the only one of its kind we have found. What's young is rice as a craft base malt; what's proven is everything underneath it.

How the field connects — documented links between the entries above

Every connection below is documented: no inferred relationships, no speculation.

  • Arkansas ↔ Dale Bumpers ↔ VLB Berlin — one study, three institutions: the cultivar malting evaluation was co-authored across the university, the federal rice center, and the German brewing institute. The study
  • Breeding ↔ brewing, inside one program — the same Arkansas breeder who co-develops the state's variety releases co-authors the malting science: the crossover the other gluten-free grains still lack already exists for rice, in one person at one center. The releases · the malting study
  • Texas Tech ↔ IRRI — the sorghum directory's crop physiologist spent seven years at the global rice center before Texas Tech, one career spanning two of these directories. His profile
  • One malting school, three grains — TU Munich–Weihenstephan's gluten-free malting corpus spans proso millet, rice, and the wider alternative grains. The same lab anchoring the millet directory appears here.
  • One review, five directories — Fox & Bettenhausen's alternative-grains quality review sits in the literature of this directory and of the sorghum, millet, corn and buckwheat directories. The review
  • The dedicated malthouses span the grains — Grouse (millet-first) also malts rice; Eckert (rice-first) anchors this page; Miller Malting, the Iowa farm malthouse, lists rice malt beside millet and buckwheat. Grouse and Eckert are worked examples on our malthouses page. Miller Malting
  • Eckert → Australia and New Zealand — the Australian dedicated gluten-free brewery TWØBAYS names Eckert Malting & Brewing and Grouse Malt House as its malt partners and resells their malts across Australia and New Zealand, carrying this page's rice malthouse into a second market. TWØBAYS malts

Research gaps — where the field's coverage runs out

These are the gaps we have found and documented. If we have missed something, tell us:

  • Rice's base-malt science is one US program deep, now at pilot scale. As of October 2026, as far as we have found, the Arkansas program plus the European malting school are the entire academic apparatus treating rice as a gluten-free base malt, atop the deepest general research base of any grain on earth. The one program is no longer bench-only: it has scaled rice malting from about 0.5 kg to about 150 kg batches across two malthouses and six breweries (BrewingScience 2026), and a 2025 Arkansas law gives an excise-tax credit for beer and sake with at least 20% Arkansas rice in the grain bill. The distance between what's known about rice and what's known about rice malting is the widest such gap in gluten-free brewing.
  • Nobody breeds rice for brewing, that we know of. Rice breeding targets food quality and agronomy; as of October 2026 we have found no program selecting rice varieties for malting traits, despite the cultivar study showing the variation is there to select on. The Arkansas group is now evaluating about 300 more rice lines and describes dedicated brewing varieties as a possibility, not yet a program. If you know of one, tell us.
  • The same information layer is missing. As with sorghum and millet, we have found no widely used per-lot reporting practice for rice malt buyers, the problem this site's Lot Reporting Standard exists to solve, across gluten-free grains.
  • No released rice malting-quality dataset, though the cultivar study exists. The germplasm and economic data are rich; a public dataset of rice malting performance, the Madison-screening equivalent, does not exist to our knowledge.

What to do while the gaps stand. Rice is the grain with the widest distance between what is known about the crop and what is known about malting it, and a brewer using it today still has to decide something. Rice as adjunct versus base malt sets out where each role holds, and rice processing in gluten-free brewing covers the handling the gelatinisation temperature forces. Conditional guidance, not settled science: it is what our record and the published work jointly support, and it is labelled that way rather than dressed up.
