Rice Research Directory

Who is working on rice as a brewing grain — and where the work lives. The rice counterpart to our sorghum directory: 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.

How to read it: the same seven categories as the sorghum directory, with the same rules. Entries are brief, factual, dated, and linked to primary sources. Descriptions are not endorsements.

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

3. Projects & Grants — funded work in flight right now

What qualifies: work that is currently funded or actively producing output, sits at the intersection of rice and malting, brewing, or food-grade quality, and has a public record.

The structural picture: rice has the richest producer-funding apparatus of any gluten-free grain — state checkoffs in the major rice states, a national foundation, and a federation — none of it yet aimed at malting. The money exists; the brewing direction doesn't.

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

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 the only dedicated gluten-free malthouse built around a single grain. What's young is rice as a craft base malt; what's proven is everything underneath it.

— The malt —

Eckert Malting & Brewing — Chico, California.

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, three directories — Fox's alternative-grains quality review anchors the literature of this directory, the sorghum directory, and the millet directory alike.
  • The dedicated malthouses span the grains — Grouse (millet-first) also malts rice; Eckert (rice-first) anchors this page; both are worked examples on our malthouses page.
  • Eckert's malt ↔ Otherwise's flagship — the rice-first maltster supplies the rice-first brewery: Calrose Crisp is brewed with Eckert's rice malt, a complete documented rice grain-to-glass chain. The trade profile documenting it
  • Arkansas ↔ this site's rice pages — the cost model and the cultivar study are already cited across our rice guidance — citation relationships that existed before this directory did.
  • Stuttgart ↔ Aberdeen — the two federal facilities run one documented germplasm loop: the rice center grows, regenerates, and characterizes; the small grains collection stores and distributes to the world. The shared handbook
  • California's checkoff ↔ UC Davis — the state rice research board operates in documented connection with the university's rice agronomy program. The connection
  • Louisiana's checkoff ↔ the LSU station — the state's research assessment core-funds the century-old breeding station's work, reported annually. The boards' own account

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. The Arkansas program plus the European malting school are, as far as we have found, the entire academic apparatus treating rice as a gluten-free base malt — atop the deepest general research base of any grain on earth. 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; we have found no program selecting rice varieties for malting traits — despite the cultivar study showing the variation is there to select on.
  • 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 public rice malting-quality dataset that we have found. The germplasm and economic data are rich; a public dataset of rice malting performance — the Madison-screening equivalent — does not exist to our knowledge.
