In my experience, Fresh-Milled flour has 7 "things" I need to allow for:
This is based on using a sourdough starter/levain. Commercial yeast (dry or fresh) will be slightly different.
1. Fresh-milled flour is usually thirstier, takes more water, than store-bought WW. This is a general rule. You will eventually find exceptions, i.e., some grain will already be high in moisture, and therefore need less water.
2. Fresh-milled flour takes more time to soften, so use 30-90 minutes of soak/autolyse (without starter/levain, depending on granularity (particle size).
