The terms “starter” and “levain” are often used interchangeably, which makes sourdough sound more complicated than it needs to be.

Biologically, they can be exactly the same thing: a fermented mixture of flour and water containing wild yeast and lactic acid bacteria. The real difference is usually not what they contain, but the job they are intended to do.

Your sourdough starter is the culture you maintain from one bake to the next. It is your ongoing source of yeast and bacteria—the small amount you preserve, feed and keep alive for future loaves.

A levain is a portion of that starter that has been fed and prepared specifically for a particular bake. It allows you to create the precise quantity, feeding ratio, hydration, flour blend and fermentation profile needed for your dough, without changing the starter you continue to maintain.

In this episode of Five Minute Friday, I explain:

• What a sourdough starter actually is
• What bakers mean when they use the word “levain”
• Whether starter and levain contain different microorganisms
• Why many recipes ask you to build a separate levain
• When you can use your starter directly in the dough
• How a levain provides greater control over timing and quantity
• Why building a levain can help protect and preserve your main starter
• Whether using one method produces better bread than the other

The important thing to understand is that a levain is not a separate type of culture and it is not inherently stronger or better than your starter. It is simply a planned feed taken from your starter and built for a specific purpose.

If your maintained starter is active, ready and you have enough of it, you can use it directly in your dough. If you want more control over the amount, timing, flour or fermentation profile, you can use it to build a separate levain.

Both approaches work. Understanding the reason behind them allows you to choose the method that best suits your recipe, routine and baking schedule.
