65% Hydration Slow-Fermented Sourdough
A loaf of sourdough is a record of time. Hours of cold fermentation deepen the flavor, the gluten develops without aggressive kneading, and the finished crust holds the dark color of a slow, hot bake.

A 65% dough is what a new baker should start on. The flour-to-water ratio is generous to flour, so the dough behaves predictably, takes shape readily, and bakes into a structured loaf without surprises.
A 24 to 48 hour ferment is the professional approach scaled to a home kitchen. The dough rests in the refrigerator for most of its life, gluten develops without effort, and the bake produces a crust and crumb that read as serious bread.

1000g total dough. Yields 1 boule, ~900g baked.

Method tips for this style
The starter has to be active and bubbly within four to six hours of feeding. If it doubles in that window, it's ready. A sluggish starter produces a sluggish loaf, regardless of schedule or hydration.
What to expect
Expect a tight, controlled crumb and a robust crust. The loaf slices cleanly and holds together for sandwiches; not the most dramatic interior, but the most reliable.
