Sourdough for Beginners: From Flour to First Loaf

Sourdough looks intimidating from the outside — a wall of jargon, wild timelines, and photos of impossibly airy crumb. Strip all that away and you are left with four ingredients: flour, water, salt, and a living starter. This guide walks you through your very first loaf without the mystique.

What You Actually Need

You do not need a stand mixer or a proofing cabinet. To bake your first loaf you need a mixing bowl, a kitchen scale, a Dutch oven or heavy lidded pot, and an active starter. A scale matters more than any gadget here, because sourdough is measured by weight, not volume. A cup of flour can vary by 30 grams; a gram is a gram.

The Simple Timeline

A first loaf is really five stages spread across a day and a night:

Mix the dough and let it rest.
Bulk ferment while the dough rises and develops flavor.
Shape the dough into a taut round.
Proof it in the fridge overnight.
Bake it hot, in a covered pot.

None of these stages is hard on its own. The skill is simply learning what each one should look and feel like.

Mixing the Dough

Start with a workable, forgiving recipe: 500 grams bread flour, 350 grams water, 100 grams active starter, and 10 grams salt. That is roughly 70 percent hydration — wet enough for an open crumb, dry enough to handle. Stir everything into a shaggy mass with no dry flour left, then cover the bowl.

After a 30 to 60 minute rest, do a round of stretch and folds: wet your hand, grab one edge of the dough, stretch it up, and fold it over the center. Rotate the bowl and repeat four times. Do this two or three times over the next couple of hours. The dough will transform from a sticky blob into something smooth and elastic.

Bulk Fermentation

This is where the magic — and the patience — lives. The dough needs to rise by roughly 50 percent and feel alive: domed, jiggly, and dotted with bubbles. At a warm room temperature this takes four to six hours. In a cool kitchen it can take much longer, so watch the dough, not the clock.

Shaping and Proofing

Turn the dough onto a lightly floured counter, fold it into a tight ball, and let the surface tension build. Drop it seam-side up into a floured banneton or a bowl lined with a tea towel. Cover it and refrigerate overnight. This cold proof deepens flavor and makes the dough far easier to score.

Baking

Preheat your Dutch oven to 250°C (480°F) for at least 30 minutes. Tip the cold dough onto parchment, make one confident slash across the top with a sharp blade, and lower it in. Bake covered for 20 minutes, then uncovered for another 20 to 25 minutes until deeply browned. The lid traps steam so the loaf can expand before the crust sets.

Cooling — Yes, Really

Let the loaf cool for at least two hours before slicing. The interior is still cooking as it cools, and cutting early gives you a gummy crumb. This is the hardest instruction to follow and the most important.

Your first loaf may be dense, flat, or oddly shaped. Bake it anyway, eat it proudly, and take notes. The second loaf is always better than the first, and by the fifth you will wonder why it ever seemed hard.

Reading the Dough, Not the Recipe

Every kitchen ferments at its own pace, so treat printed times as rough guides rather than promises. A recipe written for a 24°C kitchen will run fast in summer and slow in a drafty winter room. Learn to read the dough instead: it should feel pillowy and alive, jiggle when you shake the bowl, and hold a gentle dome. Poke it with a wet finger — the dent should spring back slowly, not vanish instantly or stay sunken. These tactile signs are worth more than any clock, and they are the real skill you are building. The first few bakes are as much about training your hands and eyes as they are about bread. Keep a simple notebook: jot the flour, the temperature, the timings, and how the loaf turned out. Within a month those notes become your own personal recipe, tuned to your flour, your starter, and your kitchen.
