1. How would you describe rye bread?
Rye bread is denser in texture, darker in color and richer in flavor than wheat bread. Rye breads today are made of a combination of rye and wheat flour, ranging from 50% to a 100% rye content. As the percentage of rye flour in the bread increases, the resulting baked loaf will be denser, darker and richer in flavor.
Caraway seeds are often added to rye bread, while unique rye bread recipes could include ground spices such as fennel, coriander, aniseed, cardamom or citrus peal.
2. Why is rye bread so dark?
The exceptionally dark colored rye breads is a result of the caramelization of molasses syrup in the dough when it is subjected to heat in the oven. The rye bread is also left to bake overnight in a receding heat, which allows for a generous caramelization of sugars, resulting in a very dark loaf that is not burnt.
However, some rye breads today have added coloring to make it seem darker than it should be. These bread typically are baked quickly in the oven and does not have the same rich flavors as true rye breads made with molasses syrup baked overnight.
3. Is rye bread considered whole grain?
The rye flour used in rye bread can be white or whole grain, depending on the extraction rate of the flour. Light rye flour is synonymous to white rye flour, where only the endosperm of the grain is milled into flour. Dark rye flour is synonymous to whole rye flour, where the whole grain is milled into flour.
4. Is rye bread unleavened?
Rye bread is leavened using conventional yeast or wild yeast from a sourdough starter. Fermentation in rye bread produces carbon dioxide gasses, but because gluten is unable to be formed in rye bread, the gasses easily dissipates out of the dough, causing the baked loaf to be dense.

One study with 51 constipated adults reported that eating rye bread was more effective than eating wheat bread or laxatives at treating constipation. (6)
