For best results, use an active, bubbly starter that has peaked within the last few hours, and adjust water slightly if your whole wheat flour absorbs more or less moisture. Maintaining dough temperature around 75–78°F helps produce consistent fermentation, so in a cool kitchen extend bulk time, and in a warm kitchen shorten it. A long cold proof in the refrigerator will improve flavor and make scoring easier, while baking in a preheated Dutch oven traps steam to achieve the best oven spring and crust. If the crust darkens too quickly, tent the loaf loosely with foil, and always allow full cooling so the crumb can set and avoid gummy slices.
