Barley

Barley is a grain. In bakery use, it is usually malt rather than the base of a barley loaf.

U.S. wheat flour identity allows malted wheat, malted wheat flour, malted barley flour, or a combination, to compensate for a natural deficiency of enzymes — with malted barley flour not more than 0.75 percent ¹. Whole wheat flour identity repeats the same malt permission. The mill may already have used Malt from this grain. That is enzyme correction inside Wheat flour, not a claim that barley is wheat.

Barley is not Wheat. Pearled barley in a soup is a different food from malted barley flour in a dough. Milling and malting decide which of those you bought. Malted barley with Hops is also the grain in Beer — a malt beverage, not 21 CFR 137.

Baking. A pinch of enzyme-active malt can feed fermentation and color crust; too much enzyme makes gummy crumb. The craft is Baking.

What to notice. Whole barley is a hard kernel with a crease. Malt smells sweet and grainy. If a flour spec already lists malted barley flour, you are looking at this ingredient after the maltster and the miller, not at a soup grain.
