Sourdough Starter Manager

Log each feed, watch your starter rise in a 3D jar and record when it peaks. After two feeds it learns your own starter’s timing, so you know when it will be ready.

It is easy to look at a sourdough setup online and assume you need a drawer full of specialist gear before you can bake a decent loaf. You don’t. A short list of well-chosen tools covers everything, and most of them are cheap. This guide walks through what actually matters — scales, Dutch ovens, starter jars, proofing baskets, scoring tools and thermometers — and how to choose each without overspending. If you’re still building your first culture, pair this with the active sourdough starter guide.

Start here: a digital scale

If you buy nothing else, buy a digital kitchen scale. Sourdough is built on weight, not volume, because flour is wildly inconsistent by the cup — scoop it loosely or pack it down and you can be off by 30% or more. Every hydration percentage and feeding ratio you read about assumes you’re weighing your ingredients.

1-gram resolution enough for whole loaves; a 0.1g scale is a nice bonus for small starter feeds but not essential.
A tare button used constantly to zero the bowl and add ingredients one at a time.
At least 3kg capacity a full mixing bowl of dough and flour adds up fast.

A good scale is what makes the hydration calculator and feeding calculator useful — without accurate weights, the numbers are just guesses.

The Dutch oven: your at-home steam trick

The single biggest jump in crust quality for most home bakers comes from baking inside a Dutch oven. In the first minutes of the bake the dough releases moisture as steam; a heavy lidded pot traps that steam around the loaf, keeping the surface soft and elastic long enough for the bread to spring upward. Remove the lid partway through and the humidity escapes, letting the crust dry, crisp, and colour. You can mimic this with a stone and a tray of water, but it’s fussier and less reliable for a single loaf.

Size A 4–6 quart pot (about 4.5–5.5 L) fits a standard 500g-flour loaf. A 5-quart round is the most versatile; for batards, an oval of similar capacity.
Material Enamelled cast iron is easiest — no seasoning, easy to clean. Bare cast iron is cheaper and just as effective but needs care. Both hold heat beautifully.
Lid fit A snug lid traps steam better. Avoid pots with steam vents for bread.

Preheat it empty and bake hot, confirming doneness with a thermometer — see the internal temperature guide.

Starter jars: simple, clear, roomy

Your starter lives in its jar, so it pays to get this right — though “right” is cheap.

Glass and clear so you can watch the bubbles and the rise.
At least double the volume a vigorous starter can triple; a 750ml–1L wide-mouth jar is the sweet spot.
Wide-mouthed so stirring, feeding, and scraping are easy.
Loosely lidded or vented never sealed airtight — fermentation produces gas that needs to escape.

A humble trick: wrap a rubber band around the jar at the starting level after a feed to see exactly how much it has risen. For the mechanics of keeping it fed, see how to feed your sourdough starter.

Proofing baskets (bannetons)

A banneton is the round or oval basket the shaped dough rests in during its final proof. It wicks a little surface moisture for a drier, easier-to-score skin, and its coils press the familiar spiral pattern into the crust. You don’t need one to start — a bowl lined with a well-floured tea towel works fine. If you do buy one, match the size to your loaf (a 9-inch round suits a 500g-flour boule), choose classic rattan for the spiral pattern (or plastic-coil for easier cleaning), and flour it generously with rice flour, which resists sticking better than wheat flour. The basket only earns its keep if the dough is shaped with enough tension to hold its form.

Scoring tools: a lame or a blade

Scoring — slashing the top just before baking — gives the bread a controlled place to expand instead of bursting at a random seam. A lame (a handle holding a razor blade) gives the cleanest cut and lets you angle for an “ear,” but a plain razor blade or a very sharp paring knife also works. The non-negotiable is sharpness: a dull blade drags and deflates the dough rather than slicing it. Score quickly and decisively, at a shallow angle, immediately before the loaf goes into the oven.

Thermometers: take the guesswork out

An instant-read digital thermometer is the cheapest way to stop under- or over-baking. Bread is done at a target internal temperature, not a fixed number of minutes — oven and loaf size vary too much for the clock alone. Probe the centre of the loaf; the internal temperature guide lists the targets. A thermometer also helps on the input side: dough and water temperature drive how fast your dough ferments, so knowing your numbers makes bulk timing far more predictable — see the bulk fermentation guide.

Nice-to-haves (and skippables)

A few extras that genuinely help once the basics are covered, and a couple you can skip at first.

Bench scraper invaluable for handling sticky dough, dividing, and cleaning the counter. Cheap and worth it early.
Bowl scraper flexible plastic, for getting every bit of dough out of the mixing bowl.
Skip at first dough whisks, proofing boxes, and scoring stencils solve problems you may never have. Add them later, if at all.

The short list

If you want the whole guide in one line: buy a scale first, add a Dutch oven and a starter jar, then a thermometer, and treat the banneton and lame as worthwhile upgrades rather than requirements. That covers a working sourdough kitchen for a modest outlay, with no gadget you’ll regret. From here, the sourdough FAQ and glossary defines any unfamiliar terms.

FAQ

Frequently asked questions

What is the one tool I actually need to start baking sourdough?
A digital kitchen scale is the single most important purchase. Sourdough is measured by weight, not volume, because a cup of flour can vary by 30% or more depending on how it is scooped. A scale that reads in 1-gram increments lets you weigh flour, water and starter accurately, which is what makes hydration percentages and feeding ratios meaningful. Everything else — Dutch oven, banneton, lame — improves your loaf, but without an accurate scale you are guessing at the numbers that matter most.
Do I really need a Dutch oven to bake sourdough?
You do not strictly need one, but it is the easiest way to get a bakery-quality crust at home. A heavy cast-iron or enamelled Dutch oven traps the steam released by the dough during the first part of the bake, which keeps the crust soft long enough for the loaf to spring up, then crisps it once you remove the lid. You can replicate this with a baking stone and a tray of water, but the Dutch oven is more forgiving and far more consistent for a single loaf.
What size Dutch oven is best for one loaf of sourdough?
A round or oval Dutch oven of about 4 to 6 quarts (roughly 4.5 to 5.5 litres) suits a standard 500g-flour loaf. Too small and the dough touches the sides before it has finished rising; too large and the loaf spreads flat instead of climbing. A 5-quart round pot is the most popular all-rounder. If you bake longer batards, an oval pot of similar capacity gives the loaf room to extend without hitting the walls.
What kind of jar should I keep my sourdough starter in?
Use a clear glass jar with a loose-fitting or vented lid and at least double the capacity of your starter so it has room to rise. A 750ml to 1-litre wide-mouth jar is ideal — wide enough to stir and scrape easily, clear so you can see the bubbles and the rise. Avoid sealing the lid airtight, since fermentation produces gas that needs to escape. A rubber band around the jar to mark the starting level is a cheap, genuinely useful trick.
Is an expensive banneton worth it, or can I use a bowl?
A bowl lined with a well-floured tea towel works perfectly well and is how many bakers start. A dedicated rattan banneton adds two things: it wicks a little moisture from the surface for a drier, easier-to-score skin, and its coils leave the attractive spiral pattern on the crust. It is a quality-of-life upgrade rather than a necessity. If you buy one, match its size to your loaf — a 9-inch round proofing basket suits a typical 500g-flour boule.
What can I use instead of a lame to score my loaf?
A lame gives the cleanest, most controlled cut, but a plain razor blade, a very sharp paring knife, or a clean utility blade all work. The key is that the blade is thin and genuinely sharp so it slices the skin cleanly rather than dragging and deflating the dough. Score quickly and decisively at a shallow angle just before the loaf goes into the oven. A dull knife is the most common reason scoring tears the surface.
