Describing a Sorghum Beer
Each claim is marked by where it comes from: Bard's production record, a cited study, or the site's reasoning. The words build on the malt vocabulary in the sensory lexicon and carry it into the finished beer. Treat them as a working vocabulary.
What a sorghum beer is supposed to taste like
The lab record we hold is for Bard's flagship, Bard's Gold. An independent laboratory panel in February 2019 measured it at about 90% apparent attenuation, 1.004 finishing gravity, 4.87% ABV and 3.1 SRM, "bright pale gold", with diacetyl below threshold (the reliable mash). The target was "a clean, dry, restrained beer that sold for years" (three worked beers).
What that means in the glass:
- Dry. "Dry is the designed outcome, not a defect": the enzyme mash builds a glucose-heavy wort that ferments very far (why it keeps coming out the same).
- Clean. The conversion route contributes little to esters, and the fermentation is run to keep it that way.
- Grain-led. Grain, cooked sorghum and an earthy edge carry the flavour. In a trained-panel profile of malted sorghum wort, malty aroma scored 54.2 and cooked-sorghum 39.2 on a 0–100 scale, with bitter and sour near the floor (Adetunji 2013, in the sensory lexicon).
- Quieter on the nose. A controlled study brewing the same recipe on sorghum and on barley extract found "all nine measured aroma compounds lower in sorghum from day 3 onward" (Budner). Expect lower intensities, and don't read that as a flaw.
- Everything else shows. "Sorghum malt gives you a cleaner, drier, thinner canvas. Everything you hang on it shows more" (hops and yeast). Bitterness, yeast character and faults all read louder than they would on barley.
Darker beers add the roast words on Sorghum Malt Roast Profiles: toasted, caramel, nutty, cocoa, coffee.
The words
Identity notes describe the beer. Fault notes point at a cause, covered in faults by symptom below.
| Word | What it tastes, smells or feels like | Where it comes from | Identity or fault |
|---|---|---|---|
| Dry | Little residual sweetness; a firm, clean finish | A glucose-forward wort fermented far | Identity |
| Clean | No fruit, butter or sulphur standing out | Controlled fermentation on a low-ester conversion route | Identity |
| Grain | The base cereal note | Sorghum malt itself | Identity |
| Cooked sorghum | Like cooked whole grain | Sorghum malt; strongest in pale beers | Identity |
| Earthy | Soil, dry stem, or husk-adjacent | Sorghum malt; crop source; storage | Identity in balance, a fault when it dominates |
| Pale gold | Appearance: light and bright | A pale base with no roast | Identity |
| Thin, empty | Watery; nothing between the first sip and the finish | Usually a missed mash-out; a skewed sugar profile | Fault |
| Sharp bitterness | Bitterness out of proportion to the beer | Little malt sweetness to balance it | Fault |
| Harsh, grassy hops | Hops that feel disjointed on the base | A hop profile that needs a malty counterweight | Fault (hypothesis) |
| Rough, astringent | Drying, puckering mouthfeel rather than a taste | Husk or seed-coat extraction, heavy roast, high-pH sparging, tannin | Fault |
| Solvent-like, sulphur-like, dull | Stress character | A starved or stressed fermentation | Fault |
| Fruity, fusel | Ester or hot-alcohol character | Fermentation too warm | Fault in most styles |
| Buttery | Diacetyl | A diacetyl rest missed or ended by the calendar | Fault |
| Weak head | Foam that collapses before the table | Low foam-positive protein in the wort | Fault, and the one judges name |
| Stale, cardboard | Flat, papery, aged | Oxygen pickup, warm storage, package age, old malt | Fault |
| Tart, sharp | An acidic edge | Low pH, yeast stress, acid additions | A fault unless intended. Different from the sourness of infection |
| Extract twang | Concentrated-syrup note | Old or oxidised extract, a high syrup load | Fault |
| Hazy | Cloudy when it should be bright | Starch haze from incomplete conversion, solids carryover, a slow-filtering malt lot | Fault in a bright style |
Sources: the working descriptors on Sensory Evaluation of Gluten-Free Malt, the diagnostic table on Sorghum Malt Flavor and Brewing Character, and the process pages linked in the next section. The site calls the catch-all word "twang" "usually too lazy to be useful", so name the note instead.
Dry is not thin
These two get confused, and the fix for one makes the other worse.
- Dry is the design. A 1.004 finish is "not a stuck fermentation", and "chasing residual sweetness with a warmer rest or a fresh pitch after the beer has finished at 1.004 does not add body back" (fermentation management).
- Thin is a fault. "The failure mode: it finishes thin and reads empty", and "the fault is usually mash-out, not the recipe": reaching 180°F (82°C) stops the glucoamylase, and a mash-out that stalls short leaves it working in the kettle (three worked beers).
"A dry finish can be crisp when the beer has structure and harsh when the beer is thin." Describe a beer as dry when the finish is clean and firm; call it thin when the middle is missing.
Faults by symptom
When a sorghum beer tastes wrong, "the cause lives in one of three places": poor raw materials, poor yeast nutrition, or a skewed sugar profile, and "none of them is 'add more hops'" (the off-flavor triad). Change one thing at a time, and fix it on the page that owns it.
| Symptom | Likely cause, most likely first | First check | Fix | Owned by |
|---|---|---|---|---|
| Thin, empty | Mash-out missed or stalled short; a glucose-heavy sugar profile | Mash-out temperature log; final gravity against the recipe | Hit 180°F (82°C) for 10 minutes; move the conversion rest lower for a rounder beer | Temperature Programs |
| Sharp bitterness | Bitterness set for a barley beer | IBU against gravity | Start restrained: Bard's flagship ran 18 IBU on 10.5°P. "What reads as moderate on barley reads sharp here" | Hops and Yeast |
| Harsh, grassy hops | A variety that needs a malty counterweight | Which hops, and how much | Drop bitterness before changing hops. The hop bills Bard's actually ran are on the hops page | Hops and Yeast |
| Solvent-like, sulphur-like, dull | Yeast stress in a low-FAN wort; under-pitching | FAN on the malt certificate; pitch rate; fermentation start | Dose a gluten-free-verified nutrient as planned, not as a rescue; pitch for a low-nitrogen wort | Yeast Nutrition |
| Fruity, fusel | Fermentation too warm | The temperature the beer actually reached | Run cool: 20.5°C (69°F) with the American ale yeast Bard's used | Fermentation Management |
| Buttery | Diacetyl rest started late or ended by the calendar | When the rest started; taste or test before crash | Start at 5°P while fermentation is active; end it by taste or measurement | Fermentation Management |
| Weak head | Low foam-positive protein; undercarbonation; a stressed or over-attenuated fermentation | Carbonation level; hop extract dose | Trim 5 IBU and add it back as reduced hop extract; check carbonation first | Head Retention |
| Rough, astringent | Husk extraction; high-pH sparge; heavy roast; tannin | Sparge pH; roast percentage; the malt's tannin class | Control sparge pH; pull back the roast | Flavor and Brewing Character |
| Stale, cardboard | Oxygen pickup; warm or mixed storage; package or malt age | Package oxygen; beer age; a fresh batch side by side | Hold one temperature regime, cold or consistently warm, "never a mixture" | Packaging and Release |
| Tart, sour | Low pH or acid additions; yeast stress; infection | Finished pH; a forced ferment; microbiology | Separate a tart edge from infection before changing anything else | Flavor and Brewing Character |
| Hazy | Incomplete conversion; solids carryover; a slow-filtering malt lot | Starch check; runoff clarity; the lot's filtration result | Confirm conversion; settle and recirculate; compare against the last lot | External Enzymes |
For notes that start in the malt itself (grainy, earthy, mineral), the table on Sorghum Malt Flavor and Brewing Character separates malt causes from process causes.

Writing it down
Tasting notes
Write in the order a drinker meets the beer: appearance, aroma, flavour, mouthfeel, finish, using the words above. Name the note rather than the grain: "grainy, dry finish, light earthy edge" tells a brewer or a buyer something; "tastes like sorghum" doesn't.
Only describe what you've tasted. "There are no tasting notes on this page. We haven't tasted these beers" is how the site's own worked recipes handle it (three worked beers), and it's the right model. The one historical description on record is Tavern Ale's: "The rich malty taste of sorghum malt melds with a hint of fresh honey and the lightly nutty/coffee flavor of roasted buckwheat" (Tavern Ale). It names each note and where it came from.
Sell sheets
For retailers and distributors, "the sales story has to be short, accurate, and repeatable" (mobile-first, label-first), and "claims are specific but not inflated" (taste vs safety vs trust). Three words of identity and one line on the style will travel further than a paragraph. Taste matters here: "Taste gets it bought again."
Competition entries
The Great American Beer Festival runs three gluten-free categories: 26, Classic Gluten-Free Ale or Lager; 27, Hoppy Gluten-Free Beer; 28, Specialty Gluten-Free Beer. Entrants must be licensed commercial breweries; homebrew competitions run separately under BJCP guidelines. Judge feedback is worth having because gluten-free beer "has its own fault profile", and body and head retention are the faults specific to it (competitions).
What a description can't claim
- Taste isn't safety. In the site's gluten survey, "taste and safety came apart completely": a drinker who enjoyed the beer was about as likely to react as anyone else (survey results). A flavour note says nothing about gluten.
- The label rules still apply. Whether a beer can say "gluten-free" depends on what it's brewed from and who regulates its label (can you call it gluten-free?, FDA or TTB).
- A descriptor isn't a diagnosis. "Cardboard" is "a descriptor, not a diagnosis of oxidation" (sensory lexicon). Name the note, then check the cause.
