Lowering Starter Acidity
I have a 100% hydration starter that I typically keep in my fridge and feed once a week. I normally use about 20% of the active starter to inoculate the new one.
The last few times I have refreshed it, I've noticed it has a very strong alcohol smell from the high acidity. To lower the acid should I use a lower percentage of the active starter when feeding? Feed at a different stage of ripeness? Advice appreciated.
