A Pedigree of Brewing Barley · Veryation

Two ancestral rivers feed nearly every malting barley a brewer names — the English landraces and the Haná valley of Moravia. Trace the crosses across two centuries of breeding.

On this chart. The brewer-core nodes (heavier outline) are individually sourced from the Oxford Companion to Beer, Crisp Malt heritage records, peer-reviewed pedigree studies, and USDA GRIN. The lighter nodes come from the AHDB Helium pedigree files (Maris Otter, Golden Promise & 2016 Recommended-List, James Hutton Institute). In Timeline view, varieties without a recorded release year are positioned by interpolation between their dated parents and offspring (shown italic in the panel); True years shows only varieties with a documented date. Internal breeding codes are labelled per source file (e.g. IC2·MO) and never merged across files.
