Teff Research Directory
Teff (Eragrostis tef) is among the smallest cultivated cereal grains and the staple of Ethiopian cooking, where its flour becomes injera through a fermentation tradition that is centuries older than any malting literature. It is naturally gluten-free, and its map has a distinctive shape: the malting science is real but concentrated — the modern malting studies we have found cluster in one decade — while the breeding and genomics infrastructure is stronger than any grain this size deserves, running from Ethiopia's national program through a Swiss-funded improvement project to two published genomes. The United States actually grows teff at commercial scale, led by an Idaho company that puts its own run at some forty years — and the grain has already reached one American gluten-free brewhouse. What remains unbuilt is the bridge: between the grain in American fields and the malting science on European shelves we have yet to find a US malthouse or a lot standard.
Coverage is US-centered by design — this site works in the American supply chain — with international anchors included where the science is foundational; for teff, that reaches Ethiopia and the European malting groups by necessity.

4. Funders & Programs — who pays for brewing-relevant teff research (described, never endorsed)
What qualifies: a funder whose money traceably appears in teff work documented in this directory, or a standing program whose scope covers the teff-to-brewing chain.
Syngenta Foundation for Sustainable Agriculture. The field's one long-horizon private funder: has backed the Tef Improvement Project continuously since 2006, most recently with a further 2.75 million Swiss francs — the closest thing teff has to buckwheat's Koto model of a single committed patron.

IFPRI — Ethiopia Strategy Support Program (ESSP).

The 2019 workshop · The nutrition working paper · Verified 2026-08-25
The count, challenged — twice: this page first said "four" — then we pushed on our own claim and found three more inside the field's funding acknowledgments, and two more (NSF, then IFPRI-ESSP) surfaced as the projects section grew — nine. The sharper claim keeps surviving: every funder here backs breeding, germplasm, or food security. We checked for a teff checkoff, a commodity board, and a growers' association and found none; we have found no brewing-industry funding anywhere in the teff literature. That absence is a finding, not an oversight; see Research gaps.
5. Industry & Supply Chain — the commercial layer
The honest state of it: the US grows teff at genuine commercial scale — but almost entirely as either hay or flour. We have found no US malthouse offering teff malt: neither of the dedicated gluten-free malting operations in our millet and rice directories lists it. Whether the one commercial teff beer we have found used malted or unmalted teff is not documented in anything we have found. The grain exists; a published teff malting chain does not.
Proof the chain can work: Ground Breaker Brewing — Portland, Oregon. The dedicated gluten-free brewery brewed "By the Sea," a teff gose (coriander, lemon peel, salt), using teff in the grain bill for the style's wheat-like character. Per the linked coverage the brewery ran the teff whole-grain through an old cornmeal mill rather than malting it — its malted grains are listed as millet, buckwheat and rice — so this is unmalted teff in a commercial grist. Where the grain was bought is not stated in anything we have found. Coverage of teff and the beer · The beer · Verified 2026-08-25
The Teff Company (Maskal Teff) — Idaho. The US teff anchor: founded by Wayne Carlson, who by the company's account lived in Ethiopia in the 1970s — with first seed sourced from the USDA seed bank on the Washington State campus, the same Pullman collection this page's science runs on — family-run for some forty years, the largest US producer by their own account, and milling flour distributed nationwide. In the absence of any growers' association, its contract grower network across Idaho, California, Nevada, Washington, Arizona, and Oregon is the organized layer of American teff farming.

The export ban that makes US teff American. Ethiopia — the crop's homeland and dominant producer — banned exports of food grains including teff, indefinitely, after the 2008 global food-price crisis, to protect domestic food security. The structural consequence for this site's readers: any US teff supply chain is a domestic one by necessity, not by preference. Idaho and Michigan aren't competing with Ethiopian imports; they are the market. The policy analysis · Verified 2026-08-25
The Dutch teff patent dispute. The cautionary tale of teff's supply chain, and one of the most-cited crop "biopiracy" cases anywhere: a Dutch company (HPFI) signed an access-and-benefit-sharing agreement with Ethiopian institutions in 2005, patented teff-flour processing in Europe (applied 2003, granted 2007), and went bankrupt — while the patents lived on and stood in the way of Ethiopian exports. A Dutch court ruled the patents invalid for lack of inventive step (decided November 2018, announced February 2019); equivalents in other European countries survived the ruling. Anyone building a teff product chain inherits this history. Kluwer Patent Blog · IPKat case analysis · Verified 2026-08-25
The forage detour. Most US teff acreage is grown as horse and cattle hay, not grain — extension programs at Oregon State and Utah State publish teff forage guides, not malting guides, and a commercial forage-seed layer exists to serve it: seed companies such as Warner Brothers Seed (Oklahoma) market teff grass nationally as a fast, multi-cut annual hay crop. For a buyer this matters twice over: the agronomy is proven across the West and the seed is easy to buy — but the harvest, handling, and quality infrastructure was built for hay bales, not food-grade grain lots.

The gap, checked and restated: we have found no US teff growers' association and no US commodity organization — in Ethiopia the crop is organized through cooperatives rather than a crop association, and the international workshop series meets roughly once a decade rather than annually. Between workshops, the field convenes inside Ethiopia's national program and individual university groups.

How the field connects — documented links between the entries above
Every connection below is documented — no inferred relationships, no speculation.
Weihenstephan, a third time. The same TUM brewing-research institute anchors the malting science of millet, rice, and now teff — Zarnkow co-authored the definitive review for two of the three. One institute is carrying a disproportionate share of the world's gluten-free malting literature. The review
Danforth, three ways. The Donald Danforth Plant Science Center runs sorghum resilience programs on our sorghum page, co-authored the 2020 teff genome, and runs its own Gates-funded gene-edited teff program — one independent research center holding three distinct positions across this directory family. The genome · the program
Gates money, twice. The Bill & Melinda Gates Foundation funds sorghum work in our sorghum directory and the $4.9M Danforth–EIAR teff grant — the same foundation backing the two African cereals at this family's opposite ends of scale. The grant
Two routes to short teff. Bern breeds semi-dwarf teff conventionally; Danforth edits for the same trait — both partnered with EIAR, both chasing the crop's defining weakness. Teff is getting its Green Revolution twice, by two methods, through one Ethiopian institute. Bern's route · Danforth's route
The chain worked once. Ground Breaker's teff gose put American teff into a commercial gluten-free grist — the only such beer we have found. The coverage says the grain went through a cornmeal mill rather than a malthouse, and does not say who supplied it; what we can verify is that no US malthouse publishes teff malt among its offerings. The transaction, reported
Penn State's fourth grain. The same funded gluten-free brewing program appears in our sorghum, millet, and buckwheat directories — and its stated grain scope names teff. One university program spans four pages of this family. The program's scope
The export ban points the arrow home. Ethiopia doesn't export raw teff; the US grows its own. Every other grain in this family competes with imports somewhere in its chain — teff is the one whose American supply chain is domestic by law of the homeland. The policy analysis
One collection, one program, one dataset. Three entries on this page are a single pipeline: Pullman curates the federal teff collection, the UNR program screened 368 of its accessions, and the 2025 phenotyping dataset is that same work published. The genebank, the breeding program, and the newest dataset in this directory are one thread. The collection's home · the published thread
All funding roads run through Debre Zeit. Syngenta's money arrives via Bern, Gates's via Danforth, McKnight's directly — every major funder this page documents converges on EIAR's Debre Zeit center. No other grain in this family has a single institution at the end of every funding line. Syngenta's line · Gates's line · McKnight's line
Cornell, three ways. The university publishing emergency-forage guidance for New York growers is also the sole non-Ethiopian partner on the McKnight Tef II grant — and the CCRP's scientific director holds a Cornell chair. One institution touches teff's American hay identity, its Ethiopian food-crop identity, and the funding program between them. The factsheet · the partnership · the chair
Perugia, twice. The Italian Brewing Research Centre that anchors rice malting science in our rice directory supplies the senior authors of teff's best published brewing numbers — the Witkop study. Two grains in this family owe their process science to the same Italian brewing lab. The Witkop study
The industry began with a genebank withdrawal. Wayne Carlson's first teff seed came from the USDA seed bank on the Washington State campus — the same Pullman collection UNR screened four decades later. The entire US teff industry and the newest US teff science grew from one federal collection. The founding story
November belongs to two of our grains. The Whole Grains Council's grain-of-the-month calendar pairs teff with millet — a standing annual US consumer moment shared across two pages of this directory family. The calendar entry
Ethiopia guards teff twice. The export ban keeps the raw grain home; the patent fight took back the processing rights abroad. Two different legal instruments, one national posture — and together they explain why any American teff chain is domestic end to end, from Idaho seed to the mill. The ban · the patent ruling
Reno, twice. UNR houses both the sorghum-for-malting program in our sorghum directory and the only active US teff grain-breeding program — making one arid-lands university the most concentrated US node for underexplored gluten-free grains. The teff program
The Bern–Debre Zeit axis. Syngenta Foundation money flows through Bern's Institute of Plant Sciences into varieties EIAR releases to Ethiopian farms — a twenty-year single-funder pipeline, teff's version of buckwheat's Koto model. The pipeline
Two genomes, one crop. The 2014 Bern genome and the 2020 MSU–Danforth assembly are successive generations of the same resource — an orphan crop with better genomics than several majors. 2014 · 2020
Assefa's Texas connection. Ethiopia's national teff coordinator trained as a research associate at Texas Tech — an institution on our sorghum page — one of several person-level threads between teff and the sorghum research world. His profile
Pretoria's tropical-cereal orbit. Taylor's program touches sorghum, maize, millets — and teff, through starch characterization and the standard encyclopedia entry. The tropical-cereals school treats teff as family. The program
One paper, four directories. The UCC starch-digestibility study spans buckwheat, quinoa, sorghum, and teff — a single Arendt-group paper crossing four pages of this directory. The group's publications
The hay detour meets the missing malthouse. US teff agronomy was proven by the forage market, and US gluten-free malting was built on millet and rice — the two infrastructures run side by side, unconnected in anything we have found. That intersection is precisely where a teff malting chain would start. The forage side · the malting side
Research gaps — where the field's coverage runs out
No published US teff malting — anywhere we can find. We have found no US malthouse listing teff malt; the malting literature we have found is European and stops short of commercial practice. How the one commercial teff beer processed its grain is undocumented — an open question a conversation with the brewery would answer. The grain is grown here; published teff malt is not.
The malting corpus is concentrated and quiet. Most of teff's brewing science came from one Weihenstephan group in roughly a decade, with the 2017 Witkop study as the latest substantial addition we have found. We have found no active teff malting research program anywhere today.
Grain identity is underdeveloped. Most US acreage is forage; the food-grade layer is small and flour-oriented. Variety, storage, and lot data of the kind the 2013 JIB study showed matters for malt quality is not part of how US teff currently trades.
No funder owns the brewing question. Teff's nine documented funders all back breeding, germplasm, or food security. We have found no funder of teff malting — the gap between the field science and a brewer's kettle has, as far as we can tell, no sponsor.
The Ethiopian fermentation tradition is scientifically underexplored for brewing. Injera fermentation microbiology is studied; its implications for teff brewing largely are not — a question the field has left open.

Entries are added as they are verified, never to pad the count. A listing here is a map reference, not a citation: this directory deliberately maps the brewing-relevant teff research world — a wider circle than the specific evidence our brewing guidance is built on, which every guidance page cites directly.
