For the country bread, first prepare the sourdough. For the sourdough, mix 50 g water, 10 g wheat starter sourdough and 100 g wheat flour and let stand covered for about 10 hours at about 25 °C.
For the bread dough, mix the sourdough with wheat flour, wheat bread flour and 500 g water and let it rest covered for 60 minutes. Knead for 3-5 minutes to form an elastic dough.
Let the dough rest covered for 120 minutes, during this time knead twice briefly. Form the dough into a ball and place in a bread simmer.
Let rest for 50 minutes, in the meantime preheat the oven to 250 °C top-bottom heat. Turn the bread out onto a baking tray, cut in and bake with steam for 15 minutes.
Then reduce the heat to 200 °C and continue baking for about 35 minutes. Leave to cool on a rack.
