\item[Bulk Fermentation] The initial rising period after mixing all the ingredients.
The dough is typically allowed to rise until it increases to a certain volume. The
volume of increase depends on the flour that is used. When baking with wheat flour
the gluten amount of the flour is the deciding factor. The more gluten your flour has

flavor and texture of the final bread. It becomes tangier and fluffier. You can aim
for a \SI{25}{\percent} size increase of your dough and then slowly increase this to find your
flour’s sweet spot. This is highly dependant from flour to flour. When using low gluten
flour like rye you need to be careful as the longer fermentation can create a too
sticky dough which collapses and does not hold its shape anymore.
