Very nice oven rise. For 2 loaves

1kg flour, 30% white whole wheat, 70% white bread flour

20g salt

700g cool water

200g levain

Mixed all, some stretch and folds, bulk rise, shape and rest overnight in fridge. Bake at 450f in preheated pans (almost - someone turned off my preheating oven so they started a little lower) 25 minutes in closed pan, 25 minutes uncovered but loosely tented with foil.
