Artisan sourdough bread is made by fermenting flour and water with a living sourdough culture rather than relying only on commercial yeast. Bakers shape the dough by hand and bake it hot, producing its characteristic irregular crumb and deeply browned crust.
Artisan sourdough bread may be easier to digest for some people, and fermentation changes its flavor and texture. But sourdough does not automatically make bread healthier: the flour used and the rest of the recipe matter, too.
Artisan sourdough bread tastes sour because bacteria in the starter produce acids during fermentation. A longer fermentation or a more mature starter can create a sharper flavor, though the taste varies from loaf to loaf.
Store artisan sourdough bread at room temperature in a bread box or cloth bag, with the cut side facing down. Avoid the refrigerator, which can make bread stale faster, and know that a sealed plastic bag softens the crisp crust.
Yes, artisan sourdough bread freezes well. Slice it first and seal the slices in a freezer-safe bag so you can take out only what you need. Toast slices straight from frozen, or thaw a whole loaf at room temperature and warm it in the oven.
The irregular holes in artisan sourdough bread form as fermentation creates gas that gets trapped in the dough. High hydration, careful folding, and gentle shaping can preserve those pockets; dense spots may result when the dough is handled too roughly.
Yes, artisan sourdough bread can raise blood sugar because it contains digestible carbohydrates. Fermentation may affect the response compared with some other breads, but it does not make the bread blood-sugar neutral; portion size and the meal also matter.
Artisan sourdough bread can turn out dense if the starter is weak, the dough is under- or over-proofed, or shaping presses out too much gas. Use an active starter and judge fermentation by how the dough looks and feels, not by time alone.
Warm artisan sourdough bread in a hot oven for a few minutes to crisp the crust again. If the loaf is already stale, lightly dampen the outside before reheating; avoid microwaving it, which tends to make the crust chewy.
Artisan sourdough bread often splits along the side when the loaf was not scored deeply enough or the dough was not fully proofed. A deliberate cut across the top gives expanding gases a path to escape as the loaf bakes.

Artisan sourdough bread is made from flour, water and salt, fermented with a starter culture rather than relying solely on commercial yeast. The method has a long history across many baking traditions; today, artisan loaves are often shaped by hand and baked for a deeply browned crust and open, airy crumb.
Its gently tangy flavour and crisp crust make it welcome at breakfast or alongside soup, cheese and salads. Toast a slice for a sturdier base for eggs or vegetables, or serve it with olive oil as part of a Mediterranean-style meal. It is chiefly a carbohydrate source, with 8.5 g of protein per 100 g; a medium slice is about 40 g.
Medium
How many vitamins, minerals and how much fiber this food carries per calorie. A high score means a lot of nutrition for few calories.
Medium
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.
