Secale cereale
Domesticated later than wheat — Iron Age Europe
In the atlas
Rye began as a hitchhiker in wheat and barley. In the cold, wet north it out-competed its hosts and became the loaf of the Baltic, Germany, Russia, and Scandinavia. It does not make gluten the way wheat does. It makes pentosans — sticky, water-loving gums — and a sour culture that can ferment for a day. That is why rye bread is a different religion.
Origin. A weed in wheat fields that became northern Europe's bread
Flavor. Earth, caraway-adjacent even without seeds, cocoa, forest floor.
Worth knowing
- Secalins are the rye storage proteins; they are not a wheat gluten network.
- High pentosan content means dough is gluey; mix, don't knead.
- Pumpernickel traditionally is coarse whole rye, steamed for hours.
- Ergot (a fungus) is a historical rye danger; modern food rye is cleaned and inspected.
Flours you can make
| Flour | Extraction | Protein | Gluten | Notes |
|---|---|---|---|---|
| Whole-grain flour | 100% | 10.5% | 3.5% | Everything the berry holds — bran, germ, and endosperm. Mill 1:1 by weight. Use within days, or freeze. |
| High-extraction (85%) | 85% | 10.3% | 3.6% | Sift once through a #30–#40 sieve. Keeps most flavor and minerals, slightly stronger dough than 100%. |
| Light rye (sifted) | 75% | 10.1% | 3.7% | Second sifting (#50–#60). Lighter crumb, longer shelf life, less fiber. Bran left behind is gold in porridge. |

Grain to flour
Vital wheat gluten booster
Most bags of vital wheat gluten are 75–80% protein. The booster is added on top of the flour, not swapped in.

About 2.9 cups of berries → 4.9 cups of whole-grain flour. Whole-grain milling is essentially 1:1 by weight; sifting is where you lose bran.
How to mill it
Whole rye flour 'sets' as it hydrates. Mix, rest, mix again.
Medium-coarse for pumpernickel; finer for light rye after sifting.
Tempering: Not required.
