Spelt Sourdough Starter: The Sweeter, Gentler Culture and How to Keep It

Spelt is an old wheat — grown in Britain for centuries before the modern varieties that replaced it — and a culture kept on it tastes of that. A white spelt sourdough starter ferments briskly, smells faintly of hazelnuts, and bakes loaves with a soft, golden crumb and a sweetness that ordinary white flour does not have. It is the starter people try once out of curiosity and then quietly keep.

It also has one habit you need to know about before you bake with it. This guide covers the starter itself: what spelt does to the culture, how to feed it, the gluten question, and what it is best at. Recipes are linked at the end.

What spelt does to a starter

White spelt is spelt sifted to remove most of the bran, so it behaves more like a white flour than a wholegrain one — but it keeps the grain's character. It ferments faster than Italian '00' and slower than rye, which puts it in a sweet spot: lively enough to be reliable in a cool kitchen, slow enough that you are not racing it.

The flavour is the point. Spelt has a mild, nutty sweetness that comes through in the starter as a soft, almost buttery smell at its peak, without the sharp edge a white wheat starter develops when it is hungry. Bakers who find ordinary sourdough too sour for their family often land on spelt for exactly this reason.

The gluten question

Spelt has gluten — it is a wheat — but the gluten is different. It is more extensible and less elastic: it stretches easily and springs back weakly. In a starter that does not matter at all. In a dough it matters a great deal, because spelt dough tears if you knead it the way you would a strong white flour, and it goes from perfectly proved to over-proved faster than you expect.

So the starter is easy; the loaf asks for a lighter hand. Mix a little less, fold rather than knead, keep the hydration a touch lower than you would for bread flour, and watch the prove rather than the clock. Get that right and spelt bakes some of the most pleasant bread there is.

Feeding a spelt starter

• Ratio. 1:1:1 by weight is fine for twice-daily feeding; 1:2:2 if you feed once a day.
• Water. Spelt absorbs slightly less than strong white flour, so the starter will look a little looser at the same weights. That is normal — do not add flour to stiffen it.
• Timing. At 22–24°C expect a peak in 5–7 hours. It rises with a proper dome and a stretchy, open bubble structure, more like a white starter than rye, then falls back fairly quickly — try to catch it near the top.
• Flour. White spelt to keep it a spelt starter. Wholegrain spelt speeds it up and darkens the flavour; a few feeds of that and it behaves more like a wholemeal starter.
• Storage. Fridge between bakes, fed once a week. It keeps well, though spelt starters can develop a layer of liquid on top a little sooner than rye — that is hunger, not harm; stir it back in and feed.

What it bakes best

Anything where you want the bread soft and slightly sweet rather than chewy and sharp. It is the natural starter for a milk loaf, for sandwich bread, and for enriched doughs — the cinnamon rolls are noticeably more tender on spelt. Used at 100% in a plain loaf it gives a close, golden crumb with a thin crust; blended half and half with strong white it gives you the flavour with the structure of a normal loaf, which is the version most people settle on.

It is less good for very open, high-hydration artisan loaves — the fragile gluten will not hold big holes — and for anything you want to be assertively sour.

Convert your own, or buy one?

Feed a lively white starter with white spelt for four or five feeds and you have a spelt starter. It is a straightforward conversion because the two flours are close cousins. The only real drawback is the week it takes, during which you are baking with something in between.

Or start with one that already lives on spelt. Our white spelt sourdough starter is the same San Francisco culture as our white one — tested at NCIMB and confirmed to be dominated by Lactobacillus sanfranciscensis — kept on white spelt. It is live and never dehydrated, so it is ready to bake with about two hours after opening: 75 g of flour, 75 g of warm water, stir, wait. If you are choosing between the five flours we keep the culture on, the UK buyer's guide sets out what each one is for.

FAQ

Is spelt sourdough gluten-free?

No. Spelt is a variety of wheat and contains gluten. Its gluten is structured differently from modern wheat, which is why it handles differently, but it is not suitable for anyone who must avoid gluten.

Can I use a spelt starter in a normal white bread recipe?

Yes. At the usual 10–20% of the flour weight it leavens a strong white loaf perfectly and adds a mild nutty sweetness. The fragile-gluten caution applies to spelt flour in the dough, not to a spelt starter in a wheat dough.

Why did my spelt loaf collapse?

Almost always over-proving. Spelt dough passes its peak sooner than bread flour and has less strength to hold itself up afterwards. Prove it a little less than you think, and go by the poke test rather than the time in the recipe.

How long does a spelt starter take to activate from the pack?

Ours is live, not dried, so about two hours from opening to bubbling and ready — the same activation as every starter we sell, with the instructions in the pack.

White spelt or wholegrain spelt for the starter?

White spelt for the delicate flavour and a lighter loaf; wholegrain if you want it faster, darker and closer to a wholemeal starter. Ours is kept on white spelt.
