Knowledge › Growing malting barley
Malt quality is decided in the field long before the maltings. Plump, low-protein, high-germination grain comes from matching the right variety to the right conditions and managing the crop through its growth cycle. Here's what malting barley needs.
Best at 10–20°C during growth. Temperate, humid regions with moderate summers and mild winters are ideal, though some varieties adapt to warmer climates.
Loamy, well-drained soils with pH ~6.0–7.5, good organic matter and balanced nutrients.
A total requirement of about 500–750 mm per cycle — one reason barley is more water-efficient than many cereals.
When barley goes in the ground depends on the type and hemisphere:
Barley develops through three broad phases, each with critical moments for yield and quality:
Germination and emergence, followed by tillering (the production of lateral stems) and steady leaf appearance and leaf-area growth, up to roughly the fourth leaf.
Spikelet initiation, stem elongation and true-stem development, then heading and anthesis (flowering). Flag-leaf expansion and tiller mortality are especially critical in barley.
Grain fill through the milk, dough and hard-grain stages to physiological maturity — then harvest at the right moisture to protect germination and quality.
Every decision in the field — variety, sowing date, nitrogen, water — ultimately shows up in the grain analysis: protein, plumpness and germination. To see the targets growers aim for, read our guide to malting barley quality standards, and explore where the world's best barley grows on the Atlas.
