Why Grow Sorghum for Malt
The decision
You already know how to grow sorghum. What you need to decide is whether some of it should go to a brewing buyer instead of the elevator.
A malting contract asks for everything an ordinary grain contract does, then adds one line: germination, "because a feed buyer does not care whether the seed is alive" (Sourcing Sorghum Farmer-Direct).
The three routes, side by side
| Feed / elevator | Food-grade, identity-preserved | Malting contract | |
|---|---|---|---|
| Who buys | The elevator, feed and ethanol markets | Food processors and millers buying named white or food-grade lots | A maltster or brewery, often through a coordinator |
| What they check | Grade factors: test weight, moisture, damage, foreign material | Grade factors, plus variety identity and food-grade handling | Grade factors, identity, and germination (the 13-point spec) |
| When you commit | At harvest, or whenever you sell | Usually before planting | Before the crop exists. "Variety is decided at planting" (farmer-direct) |
| How you deliver | Into the elevator | Segregated | Never through an elevator: "Grain that reaches the silo is cow food as far as a malting program is concerned" (Grain Sourcing Overview) |
| Who carries a failed lot | Graded and discounted at the scale | Set by the contract | Set by the contract, and it has to be written down (see Risk, below) |
| Volume per buyer | Any | Varies | Small blocks: 40–60 acres per farm was typical in Bard's record |
What a malting buyer asks of you
The full list is the farmer-direct specification. These are the parts that change how you farm:
- Germination. The grain has to sprout: 85% at minimum, with a premium written in at 92% or better (What Makes Good Malting Sorghum). It's the one line you can't check by looking at the grain.
- No glyphosate or chemical desiccant at harvest. K-State notes Roundup is labeled as a harvest aid for feed sorghum and is "not recommended for sorghum grown for seed because germination may be reduced" (Where to Grow Sorghum for Malt). Grain for malt is seed. Some buyers won't take it at all: Grouse Malt House says of its seed supply, "We do not accept desiccated seed. Full stop. No exceptions" (Grouse Malt House).
- Harvest at black layer, and dry promptly. Wet weather after maturity brings the grain mold that costs germination (Where to Grow).
- Keep the lot identified and clean. Clean out the combine, bins and trailers, rotate away from gluten grains, and never route the grain through an elevator (Agricultural Cross-Contamination). Keep the field away from other sorghum, too, so the variety stays true (Identity Preservation).
- Keep the records. A lot ID from farm and bin, and a sample per bin at harvest (Grain Source and Acceptance). If you already hold grade certificates, List Your Grain uses the numbers you already have.
What happens to the lot after harvest is laid out gate by gate: Grain and Malt Storage for the bin, Safe Transport and Custody for the truck, FGIS Grain Sampling and Third-Party Testing Resources for who tests it, and the Lot Reporting Standard for what travels with it.
Why it earns a premium
A malting buyer is paying for three things a feed buyer never asks for, and each one is work on your side.
- Grain that sprouts. Germination is the line that "separates malting grain from feed grain" (farmer-direct). The specification writes the premium into it: 85% within three days is the floor, and a lot at 92% or better earns more, because "that should be visible in the price rather than flattened into a pass" (Malting Sorghum Specification).
- A lot that stays itself. A named variety, kept identified from planting to delivery and out of the elevator. The proposed specification makes that a class of its own, Malting Grade, Identified, which requires a "named cultivar with traceable seed provenance" (same source).
- More quality control than a feed lot. A sample per bin, an FGIS inspection, a protein figure, a germination test, mycotoxin limits that are "deliberately tighter than food-grade minimums," and a gluten test on each lot (Grain Source and Acceptance; Malting Sorghum Specification).
The premium pays for that work. We don't publish a figure, because it's set between you and the buyer. A contract that asks for all three and pays a feed price is asking you to carry the cost of someone else's quality.
Does it fit your farm?
Region. Malting sorghum wants a dry finish more than anything else. We'd source it from "the western Plains: eastern Colorado, western Kansas, the Oklahoma and Texas panhandles, western Nebraska and central South Dakota", harvested at black layer and dried promptly (Where to Grow). White and food-grade grain is the most susceptible to mold, so it needs the dry finish most. To see where your farm sits, the sorghum growing-region explorer maps the six-state sorghum belt and gives each region's harvest window, how dry that harvest usually runs, and its irrigated and dryland yields.
Water. By the industry's own accounting, 91% of US sorghum acres are rain-fed, and the crop needs about 30% less water than comparable grains. The crop tolerates drought, but water stress still costs yield (Sorghum, Water and Sustainability).
Scale. The brewing market is small against the crop. Even full US gluten-free beer demand would take about half of one percent of a year's US sorghum harvest. At 1% of that market it's about 21,000–24,000 bushels (How Big Is the US Gluten-Free Malt Market). At the 2025 US average of 72.6 bushels an acre, that is roughly 290–330 acres (our arithmetic). In practice that's a handful of farms on 40–60-acre blocks, so expect to be one of several growers.
Cultivar. The buyer names the variety, and it's decided at planting. A sorghum "can yield well, resist disease, and fit a farmer's needs while still making poor brewing malt" (Cultivars for Malting). Settle with the buyer whether the named line also gives you "a viable reason to plant it" (Our Testing: Blue Milo and Ivory 7).
Risk: who carries a failed lot
This clause decides whether the malting route is worth it.
In Bard's record, a malt batch went moldy. The supplier carried that batch, grain and malt both, because the agreement said so. The record's lesson for the buyer is blunt: "The loss lands on you, not the farmer, unless the agreement says otherwise" (farmer-direct). From your side of the table, the loss lands wherever the agreement puts it. Before you plant, you need in writing:
- who carries a lot that fails germination or mold testing;
- whether a rejected lot can still go to feed, and at what price;
- what happens in a bad weather year. "A contract written in a good year has to survive a year like that" (Where to Grow, on 2022).
The terms themselves are on Grower Contract Terms. They vary from farm to farm, and we're glad to help you work through yours.
The decision rule
Grow some sorghum for malt if all of these hold:
- Your farm usually finishes grain dry: western Plains, a dry September and October, harvest at black layer.
- You can harvest and dry without glyphosate or any chemical desiccant.
- You can keep a lot identified from planting to delivery, and deliver it without an elevator.
- The buyer names the variety before planting, and the variety also works on your farm.
- The agreement says in writing who carries a rejected or failed lot, and what happens in a bad weather year.
Stay with feed if any of these hold:
- Wet autumns are normal where you farm.
- Elevator delivery is your only practical route.
- You need a harvest aid to get the crop out.
- Nobody will put the rejection terms in writing.
Start small: one block, one named variety, one buyer, then decide again after harvest.
What we can't tell you yet
- A named buyer. The proof that this works is real but anonymized. Bard's planted 200 acres in five weeks in 2019 under multi-region contracts (Our Testing: Blue Milo and Ivory 7), and the farms behind that record aren't named because the counterparty is confidential (Growers).
