Pumpernickel vs. Rye Bread: What’s the Difference?

Pumpernickel is a traditional German bread made from coarse rye flour, giving it a distinctive dark brown color. Some German pumpernickel recipes incorporate whole or white wheat flour, but European pumpernickel bread usually refers to bread made with rye flour only. European bakers usually make pumpernickel bread with a sourdough starter instead of dry yeast and bake it on a low-heat setting for an entire day.

Pumpernickel in the United States differs from European pumpernickel in terms of recipe and cooking time. Most U.S. recipes use dry yeast instead of a sourdough starter, and bakeries tend to bake this type of bread more rapidly. U.S. pumpernickel is also more likely to contain wheat flour combined with ground rye than traditional European pumpernickel. The recipe may also contain artificial colorings and flavorings such as cocoa powder to mimic traditional German pumpernickel's dark rye color and taste.

Rye bread is a type of bread made with flour and rye grain. It is widespread throughout Europe, and there are many different types and baking traditions. All recipes contain rye flour, sometimes in combination with white or whole grain wheat flour, and the proportions of rye flour to wheat flour affect the bread's darkness and texture. Many recipes incorporate seeds, whole grains, and flavorings such as caraway seeds or citrus peel. Bakers can use dry yeast or a sourdough starter to leaven rye bread. Some baking traditions feature fermented rye flatbreads and crispbreads, such as Swedish knäckebröd.

Although rye bread has its roots in European cuisine, various types of rye bread are now popular in the United States. There are several U.S. rye bread variants, and they tend to use higher proportions of white or whole wheat flour than their European counterparts. Some recipes use cornmeal instead of or in addition to wheat flour. Whole-grain rye flour often features in Jewish bread recipes to make loaves or bagels. Marbled rye bread is another well-known U.S. recipe that combines rye dough with white bread dough to create a distinctive marbled appearance.

Pumpernickel is a type of rye bread, but in Europe it is distinct from other types of rye bread due to the way it’s made.

• Pumpernickel bread is a type of rye bread. The critical difference between pumpernickel and rye bread is that rye bread is a catch-all term to describe any bread made with rye flour, whereas European pumpernickel bread is a specific type of dark rye bread made with rye meal, usually without any wheat. Therefore, pumpernickel is darker and moister than light rye bread made from a combination of rye and wheat flour.
• Pumpernickel bread has a longer bake time. Another crucial factor that sets pumpernickel bread apart from many other rye bread types is its long baking time and the sourdough leavening technique. Although some rye bread recipes use a sourdough starter, most have a significantly shorter baking time. Therefore, European pumpernickel bread has a nuttier, stronger flavor than most other types of rye bread.
• U.S. pumpernickel is essentially the same as regular rye bread. The difference between U.S. pumpernickel and rye bread is less concrete. U.S. pumpernickel is less distinctive because it usually incorporates wheat flour and yeast, giving it a springier crumb structure and higher rise than European pumpernickel. Therefore, there's not much to set U.S. pumpernickel apart from regular rye bread. However, U.S. pumpernickel tends to be darker than most other rye bread types because it often contains coloring to create a dark brown appearance.
