Refrigerating a starter that's used daily
I would greatly appreciate any advice about how to best maintain my starter if I plan on using it 6 days a week.
Currently, I mix a batch of sourdough around 9pm, feed the starter at 10pm with a 1:1:1 ratio, and put it in the walk-in at 1am. The next day around 3pm, someone else pulls the starter out of the fridge and leaves it out, but does not feed it. I'm using about 1.5kg a day.
The first day of the week I pull it out about 6 hours before I mix and feed a portion of it, making sure the total will be a little more that what I need for the batch. I discard the rest.
I always thought it was best to keep the starter out if it's being used everyday, provided it's being fed on a regular schedule.
The problem we're having at my current job is that the starter is moving too quickly after I feed it at night. How can I slow it down a bit? Also, I'm assuming that feeding it every 12 hours should be sufficient. If I'm going to be the only one feeding it, can I just continue doing what I described above or will that have a negative effect on the starter?
Thank you so much for your help.
