Yeast or sourdough starter? - Google Arts & Culture? ›

Baker's yeast turns the sugar into alcohol (a very low volume which evaporates away as the dough is baked) and into carbonated gas. Sourdough starters turn the sugar into carbonated gas and lactic (and acetic) acid, which give this bread its sour flavor.

It turns out that Sourdough Bread Starter is better for you, far healthier than the dry yeast many manufacturers and home cooks have been using to make bread. Powdered yeast is processed to rise the bread really fast. It is not meant to break down gluten or Phytic Acid the same way that natural sourdough yeast does.

The culture is maintained indefinitely, fed with fresh flour and water (also called refreshing) consistently. A sourdough starter is used to seed fermentation in new dough when baking bread and is responsible for leavening (making rise) and flavoring a loaf of sourdough bread.

Sourdough relies on a mix of wild yeast and lactic acid bacteria, rather than baker's yeast, to leaven the dough. It's richer in nutrients, less likely to spike your blood sugar, contains lower amounts of gluten, and is generally easier to digest than bread made with baker's yeast.

In fact, many of the most popular sourdough bread recipes on our site (e.g., Rustic Sourdough Bread, Whole Wheat and Rye Sourdough Bread) include commercial yeast along with starter.

The rising power of one packet of yeast is about equivalent to one cup of sourdough starter, depending on the health of your starter. Knowing these two factors you can approximate a substitution of one cup of sourdough starter for one packet of commercial yeast.

Commercial yeast has been harnessed and manipulated to work in a short amount of time. It only needs an hour or two to rise fully. A sourdough starter may take up to 12 hours or longer to rise your bread dough.

After a few days, your daily 1/4 cup flour and water won't be enough to sustain your entire jar of starter, and your starter will be slow and sluggish, not much better than discard itself. But that's not necessarily a bad thing, depending on what you want to bake with it.

While our business has expanded well beyond St. Louis since then, that same sourdough starter is still used in our iconic sourdough bread and the craft of baking bread fresh each day remains at the heart of Panera Bread.

Despite the fact that traditional sourdough ingredients are flour, water, and salt, many store-bought versions include added yeast, ascorbic acid, vinegar, and oil. So, although many grocery stores may carry bread labeled “sourdough”, more often than not they are in fact fake sourdough.

Is sourdough better than yeast for gut health? ›

While baker's yeast is unable to break down the phytate complex, sourdough organisms can break down the complex very effectively. This could increase the amount of minerals available for absorption in the human gut (Leenhardt et al., 2005; Nionelli & Rizzello, 2016).

Health benefits of sourdough. The type of flour used — all-purpose, whole wheat, rye — can affect the nutritional content of sourdough bread, says Wee. But generally speaking, sourdough bread is a healthy option and can be eaten regularly as part of a nutritious, balanced diet.

It's easier on your digestive system, typically has a lower impact on blood sugar, contains prebiotics, and has more readily available nutrients. However, it typically does not contain as much fiber as whole wheat and other whole-grain breads.

The best flour blend for creating a new sourdough starter is 50% whole-meal flour (whole wheat or whole rye) and 50% bread flour or all-purpose flour. I recommend a 50/50 mix of whole wheat flour and bread flour. Why do you need to use these two types of flour?

As a general rule, 100g of sourdough starter can be used to replace one packet of yeast (a packet usually contains 5-7g of commercial yeast).

The main differences between yeast and sourdough starter are the time in which they take to leaven bread. Because of the way commercial yeast has been honed, it rises bread very quickly. In comparison, the wild yeast contained in sourdough starter can take many hours, even days, to rise bread.

Unlike baking yeast, which provides a quick rise, a sourdough starter requires a longer fermentation process, resulting in a more complex and tangy taste. Additionally, sourdough starters enhance the nutritional value of bread by breaking down gluten and making it easier to digest.

For health conscious consumers yeast free bread has many benefits and is recommended for people suffering from Diabetes, Candida and other digestive problems. Eating most types of regular bread creates sugar in our body's when our body breaks down the bread into carbohydrates and simple sugars.

In a nutshell, if you are making a lot of bread, the sourdough starter will be cheaper than yeast.

Making your own sourdough starter, or cutting to the point and buying one depends on your patience, time and sometimes skills. Some people battle for months trying to get one going, wasting huge amounts of flour while others crack it and get a sourdough starter going within a few days to a couple weeks.
