Our Testing: Blue Milo and Ivory 7
Craig and Bard's looked at named sorghums because generic sorghum was too blunt a category for brewing decisions. One sorghum source could behave differently from another, and the conclusion could become too broad: sorghum worked, sorghum failed, sorghum tasted rough, sorghum could malt, sorghum could not malt.
Those were the wrong-sized conclusions. The better question was narrower: which sorghum, handled how, malted toward what target, brewed under what process, and proven by what beer?
Blue Milo and Ivory 7 fit that larger question. They are not useful because a name alone proves quality. They are useful because named material makes it possible to ask better brewing questions. If the cultivar or source identity disappears, the brewer loses one of the first clues for explaining why a malt, wort, or beer changed.
The current public evidence has to stay cautious. For Blue Milo #4, the strongest available evidence is agronomic and supply-oriented. For Ivory-labeled material, the strongest available evidence is a Bard's malt-quality comparison row. Those are useful records. They are not the same thing as finished-beer proof.
That distinction protects the story. Blue Milo may be worth testing because the field-side record is specific. Ivory-labeled malt may be worth discussing because the malt-quality row has real numbers. Neither should be promoted beyond the evidence. The honest version is stronger: these materials helped sharpen the cultivar question, and the missing brewing records decide how far the claim can go.
Evidence Status
This table exists to prevent overclaiming. It separates agronomic evidence, sample inspection, malt-quality comparison, field judgment, and missing beer evidence.
| Material | Current evidence | What we can say | What we cannot say yet |
|---|---|---|---|
| Blue Milo #4 | Agronomic information sheet and sample inspection records | It has documented field traits, red grain, no harvested grain tannin, disease ratings, and sample inspection results. | We do not yet have public-ready malt, wort, beer, or scale brewing data for this page. |
| Blue Milo #4 sample lots | Inspection records for submitted lots | The available sample records support a supply-chain check, not a brewing-performance claim. | They do not prove extract, flavor, runoff, attenuation, or finished beer quality. |
| 2013 Ivory | Bard's malt comparison row | Ivory-labeled sorghum malt was compared by turbidity, refiltered turbidity, Lovibond, specific gravity, filtration, potential extract, and normalized color. | This does not yet prove that the row is Ivory 7 or show a finished beer result. |
| 2013 BBWW | Bard's malt comparison row | It provides a useful comparison point against the 2013 Ivory row. | It does not answer the Ivory 7 identity question. |
| Craig/Bard's field experience | Practical development experience | The working conclusion is that cultivar choice is decisive and most sorghum material should not be assumed suitable for brewing. | Public pages still need confirmed lot names, dates, and trial outcomes before making stronger claims. |
The safe conclusion is still valuable: named sorghum matters. The unsafe conclusion would be to declare a winner without malt, wort, beer, and identity confirmation.
- Identity preservedthe name stays attached to the brewing question
- Evidence separatedagronomic, malt-quality, field, and beer proof are not the same claim
- Records still decidemalt, mash, fermentation, package, and sensory proof are needed
- No winner declareduseful named material is not finished-beer proof by itself
The point is not that one named sorghum wins. The point is that evidence level has to stay attached to the name.
The proof-level visual is deliberately cautious. It keeps the useful names without turning them into claims the records do not yet support.
Blue Milo #4 Agronomic Details
Blue Milo #4 has enough agronomic detail to be a serious source candidate. That is not the same as saying it is a proven brewing cultivar.
| Trait | Reported value | Brewing relevance |
|---|---|---|
| Grain color | Red | Useful identity marker, not proof of brewing flavor. |
| Harvested grain tannin | None | Important screening detail for flavor and astringency risk. |
| Days to 50% anthesis | 66 to 68 | Helps place maturity and supply planning. |
| Plant height | 40 to 45 in. | Agronomic identity and harvest-management detail. |
| Plant color | Purple | Identity marker. |
| Panicle type | Semi-open | Agronomic description, not a brewing result. |
| Panicle exsertion | Very good / rated 5 | Harvest and field trait. |
| Standability | Rated 5 | Supply reliability clue. |
| Threshability | Rated 5 | Harvest and cleaning clue. |
| Tillering | Good, with 2 to 3 synchronous tillers | Yield and field-management clue. |
| Sugarcane aphid | Tolerant | Supply-risk detail. |
| Head smut | Excellent / rated 5 | Disease-risk detail. |
| Fusarium | Rated 4 | Disease-risk detail. |
| MDMV | Rated 5 | Disease-risk detail. |
| Downy mildew | Rated 5 | Disease-risk detail. |
| Irrigated yield | 150 to 175 bu/ac, also reported as 8000 to 9500 lb/ac | Supply potential, not brewing proof. |
The brewer should use this information to decide whether Blue Milo is worth sourcing, malting, and testing. The page should not use it to claim extract, flavor, runoff, attenuation, or finished beer quality.
Ivory-Labeled Malt Comparison
The Ivory-labeled data is stronger than a name, but still narrower than a finished beer claim. It shows malt-quality comparison values, not confirmed Ivory 7 identity or production beer performance.
| Sample | Turbidity | Refiltered turbidity | Lovibond | Specific gravity | Filtration | Potential extract | Lovibond at 8 Plato |
|---|---|---|---|---|---|---|---|
| 2013 Ivory | 563 | 35.3 | 3.805 | 1.1147 | 15 min | 0.5917 | 1.132 |
| 2013 BBWW | 145 | 12.3 | 2.677 | 1.1144 | 15 min | 0.5904 | 0.798 |
The cautious reading is that Ivory behaved differently from BBWW in turbidity and color while producing similar specific gravity under the comparison basis. That is useful malt-quality evidence. It is not yet a claim that Ivory 7 was proven in finished beer.
What We Can Say Now
Blue Milo #4 has documented agronomic and supply traits. Ivory-labeled material has documented malt-quality comparison data. Craig/Bard's field experience supports the bigger point that cultivar choice is decisive and that most sorghum material should not be assumed suitable for brewing without proof.
The current evidence should not be turned into a claim that Blue Milo #4 or Ivory 7 is a finished-beer winner. The stronger public claim can come later if the records support it.
Craig Confirmation Needed
These questions decide whether the page can move from evidence-status to brewing-result claims.
| Question | Why it matters |
|---|---|
| Is the 2013 Ivory comparison row the same material meant by Ivory 7? | The public page should not merge names without confirmation. |
| Were Blue Milo #4 and Ivory 7 malted, mashed, fermented, or package-tested by Bard's or Gluten Free Brewer? | This decides whether the page can make brewing claims instead of evidence-status claims. |
| What dates, lot names, maltster, beer style, mash method, and sensory results are available? | Public technical claims need traceable batch context. |
| Were either materials rejected, preferred, or used at production scale? | This would move the page from candidate evidence to decision evidence. |
The practical takeaway is to keep the names attached, keep the evidence level honest, and let the beer decide when the brewing records are available.
