How to Grow Barley: Six-Row Malting

Barley: Six-Row Malting

Hordeum vulgare subsp. vulgare

grass

Six-row barley is a cereal grain variety where spikelets develop in six rows along the head, making it ideal for malting in brewing and distilling applications. This heritage grain has a higher protein content and enzymatic activity compared to two-row varieties, producing distinctive flavors in beer and spirits. It's a cool-season annual grass that reaches 24-36 inches in height.

Growth Stages

1

Germination & Emergence

10-14 days

Seeds germinate within 5-10 days; first leaf (coleoptile) emerges, followed by true leaves

Ensure consistent soil moisture. Protect from birds and rodents. Maintain soil temperature 45-60°F for optimal germination.

2

Tillering

3-4 weeks

Multiple shoots develop from the base of the plant, creating a fuller plant with 3-5 tillers per plant; bright green foliage

Apply nitrogen if soil is depleted. Monitor for early pest activity. Maintain adequate moisture for tiller development.

3

Boot & Heading

2-3 weeks

Flag leaf emerges; head develops inside the sheath and breaks through; plant reaches near-final height of 24-36 inches

Increase water during this critical stage if rainfall is insufficient. Monitor for mildew and rust diseases. Support tall varieties if necessary.

4

Flowering & Grain Fill

3-4 weeks

Flowers bloom (inconspicuous); six-row heads become fully visible with characteristic configuration; grains enlarge and fill with starch

Critical moisture period; provide consistent watering if dry. Monitor for disease pressure. Avoid excessive nitrogen which delays maturity.

5

Maturation & Harvest Ready

1-2 weeks

Grains harden, turn golden-brown; heads droop; plant reaches full maturity with 8-12 grains per spikelet

Reduce watering as harvest approaches. Watch for birds and pests attempting to feed on ripe grain. Begin harvest when moisture content drops to 10-12%.

Companion Planting

Plan your garden →

Plant with:

Legumes (nitrogen fixation benefit to soil) Mustard (pest suppression) Tansy (insect repellent) Peas (nitrogen contribution)

Avoid planting near:

Onions (allelopathic interference) Fennel (allelopathic interference) Other cereal grains in close rotation (disease buildup)

Common Pests

  • Choose resistant varieties; practice crop rotation; avoid early planting dates in affected regions

  • Monitor for larvae; apply organic insecticide if threshold exceeded; encourage natural predators

  • Use netting or scare tactics during grain-fill and harvest stages; plant in fenced areas if possible

  • Improve air circulation; avoid excess nitrogen; apply sulfur dust if needed; choose mildew-resistant malting varieties

  • Rotate crops; use disease-free seed; improve drainage; apply fungicide if severe

Uses

🍳

Malting & Brewing

Culinary

Six-row malting barley is the premium choice for craft beer and whiskey production, where high enzymatic activity converts starches to sugars during the malting process. The six-row configuration provides superior enzyme content compared to two-row varieties. [source]

🍳

Whole Grains & Flour

Culinary

Barley grains can be cooked as a nutritious whole grain side dish, or milled into flour for baking breads, cakes, and porridges. Barley flour adds nutty flavor and is commonly used in Japanese and Middle Eastern cuisines. [source]

💊

Traditional Herbal Remedy

Medicinal

Barley water (infusion of boiled grain) has been used in traditional medicine to support digestion, reduce inflammation, and provide hydration. Modern research suggests barley contains beta-glucans that may support immune function. [source]

🏠

Animal Feed

Household

Barley grain and straw are excellent feed sources for livestock, poultry, and other animals, providing energy and fiber. Six-row varieties are particularly valued in organic farming systems. [source]

🎨

Ornamental & Decorative

Craft

Mature barley heads with their distinctive six-row configuration and drooping form create attractive dried flower arrangements and wreaths. The golden color and texture add visual interest to rustic crafts. [source]

Harvest Tips

Harvest when heads droop and grains are golden-brown, typically at 10-12% moisture content. Cut stems 2-3 inches above ground using a sickle, scythe, or grain cradle for small plots. Thresh heads to separate grains from chaff by rubbing between hands or using a simple flail. Dry grains completely (below 10% moisture) before storage. For malting purposes, grain should meet brewing industry standards: uniform size, high germination rate (95%+), and proper protein levels (10-13% for six-row).

Fun Facts

  • 🌱 Six-row barley contains significantly more enzymes (amylase and proteases) than two-row varieties, making it more efficient at converting starches to fermentable sugars—a trait brewers and distillers have valued for centuries.
  • 🌱 Barley is one of the oldest cultivated grains, with archaeological evidence dating back 10,000 years to the Fertile Crescent, and six-row types were prevalent in ancient beer production.
  • 🌱 The 'six-row' designation refers to the arrangement of spikelets on the grain head; each node produces three spikelets (fertile), creating six visible rows—a trait determined by a single recessive gene.
