Sourdough Starter Maintenance
Feeding
This feeding schedule minimizes discard and maximizes sour/funky flavors.
- Keep your starter in the fridge. This lets you feed at a slower pace and build up more slow fermentation flavors.
-
Feed weekly approximately 2:1 by weight. A 2:1 feed keeps the starter hungry and producing funky flavors. If your starter seems unhappy feed it 1:1 or even higher to reset the balance.
Measuring by weight is the only way to be consistent in baking. Baker's percentages always refer to the the total flour weight being 100%. So, a 100% hydration dough means equal weights of flour and water.
- Other ways to express the 2:1 feeding ratio:
- Add half the weight of your starter in 100% hydration feeding paste.
- 2 parts existing starter to 1 part 100% hydration feeding paste.
- 4 parts existing starter, 1 part flour (I typically do a mix of AP and whole wheat), 1 part filtered/spring/distilled water.
- Other ways to express the 2:1 feeding ratio:
-
Keep the starter in a vessel big enough to allow 1.5-3x expansion. I use a swing top jar with a rubber band to hold the lid but also let gas escape.
- Discard some starter if you are running out of room. See Other Recipes below for ways to use your discard. Or, just gift some to your friends!
- A clear/grey liquid on top of your starter is normal.
It is a mix of alcohol and acids that is a natural byproduct of lacto-fermentaion, sometimes called "hooch".
You can either pour it off and discard it or mix it back in when feeding.
Too much acid/alcohol buildup can harm your colony. It shouldn't be a problem if you are regularly feeding though.
Baking
The night before you want to bake, make a levain:
- Take out some starter, feed it 1:1, and leave it out at room temperature (make a bit more than your recipe requires).
- Use it as "ripe starter" in your recipe the next day.
- Any leftover levain can be discarded or fed to the main starter.
