Restoring A Sourdough Starter From Long Term Refrigeration

Restoring A Sourdough Starter From Long Term Refrigeration

I like to store my sourdough starters in the fridge and I tend to do it long-term without feeding. Whenever I am ready to reactivate a sourdough starter I take it out of the fridge, stir the liquid on top back into the starter and scoop out a small spoonful. I then drop it into a jar and add one cup all purpose white flour and three quarters cup water which is about 70 degrees F. It will feel just barely cool to the touch. Then I stir it all together and loosely cover my jar and then place it in a good location that's not too cold. In this case I chose my mantle above the gas fireplace because it was about 65 degrees. My kitchen is about 50. For this sourdough starter I used tap water. Your use of tap water may get different results.

Look at the photo below. This is my old Valentina's (Wasatch Willy's is similar) after a day and a half! From the fridge it takes roughly 36 hours to become fully active. You can tell the starter is going to be ok because after 12 hours the sourdough starter is stringy. I stir it up and dump it down the drain leaving about a quarter cup still in the jar. I feed it and let it sit for another 12 hours. Then after 12 hours I dump out most and feed it again. Within the next 12 hours it will be very active.
