Whole grain hydration, the math no one explains
Whole-grain hydration is not the same number as white-flour hydration.
Every recipe online says "75% hydration" and you mix it and it feels like 60%. Stiff, tight, no slosh. This isn't your kitchen scale lying. It's the flour.
Whole-grain flour drinks water differently. The bran and germ are still there, and they absorb moisture slowly — sometimes over hours. So at 75% you start out feeling dry. An hour in, the dough has loosened. Three hours in, it's slack.
What I do:
- Mix at the listed hydration
- Wait 60 minutes (this is the autolyse you didn't know you needed)
- Then decide if you need more water
- Add water in 5g increments, mixing by hand each time
For 100% whole wheat at 75% on the bag, I usually end up at 78–82% by the end. For a 50/50 blend, 76–78%.
The dough will keep telling you what it wants. The recipe is a starting point, not an ending one.
