Sourdough Starters

The amount of sourdough starter in a recipe can vary significantly because different bakers prioritize different aspects of the dough and fermentation process. Here’s a breakdown of the main factors influencing this variation:

1. Fermentation Time

• Less Starter (e.g., 70g)
  A smaller amount of starter means the dough ferments more slowly, allowing for:

  • Complex flavor development: The longer fermentation lets wild yeast and bacteria produce more nuanced flavors.
  • More scheduling flexibility: Bakers can leave the dough to ferment longer without it over-proofing.

• More Starter (e.g., 200g)
  A larger amount of starter speeds up fermentation because there’s more active yeast and bacteria to work with:

  • Faster process: Great if you want bread ready in less time.
  • Milder flavor: Less time for acids to develop, resulting in a less tangy loaf.

2. Hydration and Dough Texture

• Starter itself contains water and flour, which impacts the overall hydration of the dough:
  • More starter often makes the dough wetter, leading to an airier crumb if managed well.
  • Less starter can keep the dough firmer, which might suit denser bread styles.

3. Desired Bread Characteristics

• Recipes calling for more starter often aim for:

  • A stronger rise, as there's more yeast to produce carbon dioxide quickly.
  • A tender crumb due to shorter fermentation time and less acid buildup.

• Recipes using less starter often aim for:

  • A chewier texture, as the gluten has more time to develop during a long, slow fermentation.
  • A sourer taste, because the bacteria have more time to produce lactic and acetic acids.

4. Starter Activity

• Some recipes adjust the starter amount based on how active it is:
  • If the starter is sluggish, using more ensures enough fermentation power.
  • If it’s very active, less is needed to avoid over-proofing.

5. Baker's Preferences

• Every baker has their own method and goals, so recipes reflect individual experimentation and tradition. Two recipes with similar ingredients can vary widely based on personal adjustments to starter quantity.

How to Choose the Right Amount

It often comes down to experimenting with your schedule, your starter's activity, and the flavors/textures you enjoy. Start with a recipe, note the results, and adjust based on your preferences!
