How To Switch Your Sourdough To A New Type Of Flour - Cultures For Health (2024)

Sourdough comes in many forms: white-flour sandwich bread, whole-wheat peasant loaf, rustic spelt boule, or dense rye. All of these breads are delicious in their own way.

It is a simple task to use a different type of flour for baking, no matter what type of sourdough starter is used as leavening. If you prefer to branch out and try a completely new starter, there are a couple of choices.

SWITCHING TO A NEW TYPE OF SOURDOUGH STARTER

1. You may choose to purchase a new type ofsourdough starterand begin from scratch.Compare our list of sourdough startersand decide which is right for you.
2. More practically, some of your current sourdough starters can be converted to a new type of flour. It is fairly easy to convert a starter between white,whole wheat,rye, spelt, or other gluten-containing flours.
3. Switching to a gluten-free flour is a bit more tricky, as it tends to require more feedings to become vigorous and maintain its efficacy in baking. In this case, it may be easier, to begin with, an establishedgluten-free sourdough starter.

BEFORE YOU SWITCH

• Always revive a dried sourdough starter first with the flour type indicated.
• Do not attempt to switch flours until your sourdough starter has been fed for at least a week and is healthy and happy, bubbling and growing.

INSTRUCTIONS FOR SWITCHING TO A NEW FLOUR

1. Dividethe active starter into two portions.
2. Placeone-half safely in the refrigerator as a backup if the starter does not acclimate well to the new flour.This backup should be fed with its regular flour to keep it healthy.
3. Feedthe second half with the new flour atroom temperature.
4. Within a few feedings, the starter should be converted to the new flour.
5. Once it is bubbling and growing reliably for a few consecutive feedings, it is ready to use for baking.

TROUBLESHOOTING A NEW FLOUR

• Not all flours work alike in sourdough, so the starter may go through anadjustment periodin which it is not as vigorous.
• Whole grain flourstend to contain more organisms to feed the yeasts and bacteria. Switching from whole grain flour to white flour may cause a decline in the health of the starter.
• Rye flour, in particular, is very well-suited as food for sourdough starters. Switching a rye starter to a new flour may cause a change in the health of the starter.
• Flour that has just been ground can be a little "raw" for the starter to utilize.Aging freshly ground flour for a week or more allows for the development of more healthy organisms the sourdough starter can utilize.
• If, after an adjustment period, the sourdough starter appears to be less vigorous than before,try feeding it a blend of the new flour and the old flour for several feedingsto give it a boost.
• If all else fails, discard a less-than-stellar new sourdough starter and return to the refrigerated portion of the original starter. Later, either repeat the flour switch as recommended above or try a different flour.As long as a portion of the original starter is always retained, endless attempts and trials can be made with different flours.
