Sourdough Bread: 100% Sourdough Rye Bread

There are many ways to make rye bread, but very few versions contain 100 percent rye flour. Rye has so little of its unique type of gluten (6 to 8 percent) that it is hard to develop the structure and lift necessary for a decent crumb without the addition of a fair amount of high-gluten wheat flour. However, there are many people who love dense rye bread, and there are others who eat it because they can tolerate the gluten of this bread but not the gluten in wheat breads. A lot of drama goes on inside a sourdough rye bread. Rye flour is high in natural sugars and dextrins and contains pentosan, a gum protein that causes the dough to become gummy if it is mixed as long as wheat breads. Also, the wild-yeast starter creates an acidic environment that slows down the enzymatic release of sugar during the mixing cycle, but at the same time allows for the sugars to emerge from the grain during the fermentation cycle as the enzyme activity kicks in. If properly mixed and fermented, the result is a sweet, creamy, yet chewy texture quite unlike that of any other bread.
