What is barley?
In the beginning there was Hordeum spontaneum Now there is …. . . Hordeum vulgare* 2 n = 2 x = 14 5. 3 Gbp ~ 30, 000 genes Self-pollinated (hermaphroditic) * Technically speaking spontaneum and vulgare both subspecies of H. vulgare
Center of origin and domestication
Domestication traits Spontaneum Vulgare Shattering (brittle rachis) Shattering resistant (non-brittle rachis) 2 -row, 6 -row Adhering hulls Adhering, non-adhering (naked) Winter annual Winter, facultative, and spring annual Apparent diversity Actual diversity
Domestication and evolutionary bottlenecks Apparent diversity Actual diversity The imperative for conservation and characterization of genetic resources
The domestication traits, the genes, and the mechanisms Locus/alleles Phenotype Mechanism Btr 1, Btr 2 Shattering/retention Loss of function deletions Vrs 1 2 -row/6 -row Loss of function deletions Nud Hull adherence Loss of function deletions Vrn 1, Vrn 2, Vrn 3 Growth habit Loss of function deletions Ppd 1, Ppd 2 Loss of function deletions Photoperiod sensitivity
Inflorescence type • 2 -row vs. 6 -row • 1 gene/30, 000 genes
Covered vs. Naked • 1 gene/30, 000 genes
Growth Habit winter, facultative and spring 3+ genes/30, 000 genes
Growth habit and allied traits Low temperature tolerance Vernalization sensitivity Photoperiod sensitivity (short day) Winter Facultative Spring Yes No No Varies Yes Varies
Facultative growth habit Flexibility! Fall planting Cold tolerance on demand Spring planting Cold tolerance not needed
Why barley? Beverage, food, feed
Beverage The transformative power of malting Steeping, Germination, Kilning Time (~1 week) temperature (50 o – 350 o) Moisture (10% – 50%)
Barley malt • The base of beer and spirits • Culinary uses • The economic driver of barley
Barley malt and beer styles • All-malt beers • Reinheitsgebot compliant beers • Most US craft beers • Brewing with adjuncts • American standard lager • Happoshu • Beer of the Third Kind
Barley malt specifications: • Starch-related: Malt extract • Enzyme-related: Diastatic power • “Modification” - Not too low, not too high…
Malt quality parameters: Buck Full Pint Copeland naked winter 6 -row - taste the malt covered spring 2 -row - taste the beer covered spring 2 -row - the ace of base malts
One variety: Many Malts Time, temperature, moisture
Food barley • Symptoms: Cardiovascular disease, diabetes, obesity • Part of the problem: Diets low in fiber, high in refined grains, sugars, and saturated fats • Part of the solution: Barley - a rich source of soluble fiber
Food barley Soluble dietary fiber • Normal (~5%) vs. High (~15%) beta glucan • Is high better? • 1 serving “normal” = RDA • Whole grain nutrition vs. beta glucan extraction
Food barley in the world and the US • Culinary traditions in Himalayas, North Africa, Andes • Health and satiety
Local food barley # STRKR (Streaker) • First Alternative Coop • Barley scones at OSU UHDS
Feed Barley • Greatest usage, worldwide • Feeding value (and price) corn discount • Nutritional needs of ruminants, nonruminants, and poultry • The role of the hull - ~ 12% of yield
Feed barley or Malt barley? The dogma: “A good malt barley is good feed barley, but not the reverse” The (crafty) truth: “With changes in malting protocol a feed barley can be an excellent malt barley”
Feed (Forage) Barley • Hooded barley • hoods, rather than awns • usually cut green for hay or silage
Barley: History – Explains the Present 1 mile per year (? )
Migration and specialization Europe Beer • Hulls, spring growth habit, 2 -row Feed (food and some beer) • Hulls, spring/winter/facultative, 6 -row “The decree known as the Reinheitsgebot, issued in Ingolstadt in 1516, had three aims: to protect drinkers from high prices; to ban the use of wheat in beer so more bread could be made; and to stop unscrupulous brewers from adding dubious toxic and even hallucinogenic ingredients as preservatives or flavourings. ”
Migration and specialization North Africa/Iberian peninsula – feed/food • Hulls, winter/facultative growth habit, 6 -row
Migration and specialization “Barley helped ancient Tibetans climb to 3400 meters”
Maximum nutrition and return The hull Insoluble fiber Naked, spring growth habit 2 -row, 6 -row
Migration and specialization Americas (17 th century - ) North and Meso • Hulls, spring growth habit, 2 -row malt –Europe • Hulls, spring growth habit, 6 -row malt – Europe/Asia • Hulls, spring/winter/facultative 6 -row feed – Iberian peninsula/North Africa
Migration and specialization Americas (17 th century - ) South • Southern cone: Hulls, spring growth habit, 2 -row malt – Europe • Andes: Naked, spring growth habit, 2, 6 -row food
Migration and specialization Australia/ New Zealand (18 th century - ) • Hulls, spring growth habit, 2 -row malt – Europe
Migration and specialization Central and East Asia • Hulls, spring growth habit, 2 -row malt –Europe

Barley: Production considerations
Supply: • 1 seed becomes 50 - 100 seeds • 100 lbs becomes 5, 000 – 10, 000 lbs Demand: • $130/ton feed • $ 1. 5 X – 3 X feed for malt or organic feed • Food barley $ = wheat $ (? )
