Sorghum Malt Screenings 2002–2004: Breeding Lines and Cultivar Search
Two more screening datasets from the same program as the USDA Madison work: 24 samples from the 2002–2003 submissions and 50 from the 2004 cultivar search across Missouri, Kansas, and Nebraska — breeding lines, experimental materials, and named hybrids, with wort turbidity measured directly.
This dataset supports: Cultivars for Malting and the USDA Madison Screening — same program, earlier rounds.
These tables extend the published record backward: before the 25-cultivar Madison screening, the program screened breeding lines (Texas A&M-lineage Tx materials, SorTech experimental lines) and early hybrid candidates. Two things make this set distinct. First, it includes experimental breeding material, not just commercial hybrids — the kind of lines a breeding program crosses from. Second, it measures turbidity directly — the wort-clarity problem our whole flavor-first doctrine treats as a first-class brewing concern, quantified per sample.
Reading notes — honesty first
- The DP column's units are not labeled in the source spreadsheet. Its values (roughly 5–14) are not directly comparable to the Madison table's ASBC numbers (19–46); diastatic power is reported in multiple unit systems and this source does not say which it used. We publish the column as recorded and flag it — do not cross-compare DP between this page and the Madison page.
- "Grain protein" is labeled "barley protein" in the source — a barley-template column header applied to sorghum samples. It means protein of the ungermed grain.
- Wort clarity is scored 1 (clear) to 3 (hazy); "n.d." = not determined in the source. All percentages dry basis.
- Sample identifiers ("Row27799 R Tx2819") are preserved exactly as recorded — row numbers are field-plot identities, R/B prefixes are grain-color codes in the source's convention.

Transcribed programmatically from the original program summary spreadsheet (two sheets, 74 sample rows) and rounded for display; full precision in the CSV. The unlabeled-DP-units caveat above is part of the record — publishing a known ambiguity honestly beats hiding the column.
