Barley (Hulled)

Whole-grain flour · Weak gluten

Whole grain needed: 505 g
Flour you’ll get: 500 g
Bran left behind: 0 g
Protein in that flour: 57.5 g · 11.5%
Natural gluten: 2.5%
Add VWG: 12.1 g
After VWG: 13% protein · 4.1% gluten

About 2.7 cups of berries → 4.3 cups of whole-grain flour. Whole-grain milling is essentially 1:1 by weight; sifting is where you lose bran.

How to mill it

Buy hulled, not pearl, if you want the whole-grain story.

Medium. Pearl barley mills into a very pale flour.

Tempering: Skip.

Everything the berry holds — bran, germ, and endosperm. Mill 1:1 by weight. Use within days, or freeze.
