Overview (Has Gluten)

Rye flour is derived from rye (Secale), a cereal grass of the wheat family. Its origins are murky, but evidence of it being grown as a crop has been found in Neolithic era settlements in Turkey and central European sites dating to 1800 BC. Its ability to thrive in poor soil conditions and even under winter snow made it a popular crop in Central and Eastern Europe since the Middle Ages, where it is still widely cultivated.

Separating the germ and bran of rye berries from the endosperm is difficult. For this reason, rye flour generally has more nutrients than refined wheat flour. Commercially available rye flour can be found in light, medium and dark varieties. The darker the flour, the more bran has been used in making the flour. Dark flour is also coarser than the lighter colored, finely milled rye flour, which contains less bran.

Rye has significantly lower levels of gluten than wheat, but can make a yeasted loaf of bread without any gluten additives. Often, however, bakers will add a small amount of wheat flour to help the bread rise better. Bread made with rye is typically dense with a dark coloration and is described as having a rich, almost fruity flavor. Since it is also used in making sourdough bread, it has been described as having a hearty, sour flavor, too.

Rye is high in fiber and is one of the most protein-rich grains around. Rye is also a good source of calcium, zinc, iron and B vitamins, as well as vitamin E. Most of these nutrients are lost in the commercial process used to create light rye flour, so home milling rye grain is the best way to retain the nutritional value of whole rye. Although rye breads are the most common use for rye flour, it can also be used for pancakes, muffins, scones, and blinnies.

Note: Weight of a cup (or partial cup) of flour varies depending upon whether it is lightly sprinkled into a measuring cup or compacted. Most recipe measurements are based on sifted flour as a way to arrive at more uniform measurement.

Gluten Content & Allergen Information

Rye contains gluten, so anyone with Celiac disease or gluten intolerance should avoid rye flour. Allergic reactions can range from hives and an upset stomach to swelling of the tongue and constriction of the airways so extreme as to cause asphyxiation.

Paleo Diet

The Paleo Diet seeks to emulate the hunter-gatherer diet of our stone-age ancestors. The emphasis is on wild plants and meats similar to what ancient man would have consumed. As such, dairy products, refined sugar and processed oils are off limits. While many Paleo Diet followers also avoid grains, there is ample archaeological evidence to show that grains were part of Paleolithic era man’s diet.

“We love the mill! We use it every day for things from bread, to pastry and it is phenomenal. The biggest selling point for me was the fineness since that would mean we can really do some great pastry with it in addition to bread. It definitely has been great!"
