My starter dislikes the cold.....? What can I do?
I'm new here - what a wonderful site! I'am fairly new to sourdough too, I have been baking with it for almost two years and still learning. The terminology I use might be "wrong", I hope you still understand me.
I'd like to ask for your help to understand the reason + solution for the problem I have with my starter.
My starter is originally made of juice of wild yeast captured from fruit, and I've been using it for around 8 month (100% hydration). The juice is maintained too by adding some fresh fruit evert now and then.
My usual pattern is:
Sunday baking, feeding. Wait til it rise, and back into the fridge.
Friday, out from the fridge. Feeding every ~12 hours to prepare for the Sunday baking.
Occationally when I was away from home, it was "starving" for 3-4 weeks but after a 3-5 refreshes it got active again.
The problem started early this year.
It was no sign of life after Friday-feeding. I had feed using the wild-yeast juice to get it up.
Next week, I took out the jar already on Wednesday to feed. No sign of life.
Week after, out already on Tuesday morning to feed. Again no sign of life.
I decided to move the jar to the balcony instead (winter=cold) and it did better. It simply survived more days until it got "flat with no sign of life".
I kept on feeding daily hoping the yeast to grow very strong, and did put it back after one week of intensive feeding but again, flat after few days in the fridge.
Now balcony trick does not work anymore.
Of couse, every time I refresh using the wild yeast juice, it get very active again but it means I add new yeast to the jar so it's kind cheating.
What I want is to have the yeast-guys in the jar to survive from week to week!
Past 10 days, I been trying to revitalise my flat starter by feeding-resting (no bubbles but still... It tastes sour though) I am giving up now. My rye-sour is living in fridge and doing excellent.
I've tried to feed everything from 1:1:1 to 1:3:3 (approx).
The fridge is 6 degrees celsius, room temperature 22, balcony was arond 6-10 deg C. While rising, I put the jar on top of the fridge, where it is around 26 deg.
So what I wish to understand is....
-what is wrong here??
-what can I do to make it survive week to week, using the fridge?
Thanks a lot!
