1 slice (medium) of Sourdough rye bread (40 g) has 92 calories. That works out to 230 calories per 100 g. It contains 17.6 g of carbs, 2.6 g of protein, 0.9 g of fat and 2.2 g of fiber. Its 0.4 mg of Manganese covers 19% of the Daily Value. Its glycemic index is 48 (medium), so it raises blood sugar at a moderate pace.
Sourdough rye bread is made with rye flour and a fermented starter, in a style long associated with Northern and Central Europe. Its fermentation gives it a gentle tang, while the loaf’s close, moist crumb and sturdy crust make it denser than many wheat breads.
In its traditional regions, it is often served with cheese, cured fish or hearty soups; elsewhere, it works well for breakfast toast and substantial sandwiches. It is a fibre-rich choice, with 5.5 g of fibre per 100 g. Pair its earthy flavour with crisp vegetables or a fresh, lighter topping if you prefer a less hearty slice.

An EatBetter score computed from fiber, protein and calorie density. A high score means staying full longer on the same calories.
Both scores are calculated per 100 g and do not change with the selected portion. The satiety score is EatBetter's own calculation, not a clinical measure.

Sourdough rye bread is bread made with rye flour and a fermented sourdough starter, which gives it a tangy flavor. Many recipes also use wheat flour to help the dough rise, so the name alone does not tell you whether a loaf is made entirely from rye.
Sourdough rye bread is often dense because rye does not form the same stretchy gluten network as wheat, so it traps less air during rising. A moist, close crumb with small holes is typical of many rye loaves, rather than a sign that the bread is underbaked.
Sourdough rye bread often provides more fiber and a more filling texture than white bread, particularly when it is made with whole-grain rye. The comparison depends on the recipe: some loaves contain substantial wheat flour or added ingredients, so the name alone does not guarantee a whole-grain bread.
No, sourdough rye bread is baked, and the heat kills most of the live microorganisms in the starter. Fermentation can still shape its flavor and texture, but eating the finished loaf is not the same as consuming a food with live probiotic cultures.
Yes, sourdough rye bread can be made without wheat flour, though a rye-only dough tends to be stickier and produce a denser loaf. Rye itself contains gluten, so replacing wheat flour with rye does not make the bread suitable for a gluten-free diet.
Keep sourdough rye bread in a bread box or a breathable bag at room temperature, with the cut side covered. Refrigeration can make bread go stale faster. If you see mold anywhere on the loaf, discard the whole loaf rather than cutting away the visible spot.
Yes, sourdough rye bread freezes well. Slice it first and seal the slices in a freezer-safe bag so you can take out only what you need. Thaw slices at room temperature or toast them from frozen, and avoid repeatedly thawing and refreezing the loaf.
Pumpernickel is a particular style of rye bread, traditionally baked slowly from coarsely ground rye, which gives it a very dark color and distinctive flavor. Sourdough rye bread describes bread fermented with a sourdough starter; it may be lighter and need not be pumpernickel.
Sourdough fermentation breaks down some compounds in the dough and can change how the bread feels and tastes, but it does not remove rye’s gluten. People with celiac disease must avoid sourdough rye bread; fermentation does not make it safe for them.
Sourdough rye bread pairs well with smoked fish, sharp cheese, eggs, or hearty soups because its tangy flavor stands up to savory toppings. Toasting brings out its aroma, while a thick slice can also be served untoasted alongside stews or salads.
