Spelt Sourdough Bread (Dinkelbrot): Why Austrian Bakers Love This Grain
Everything you need to know about baking spelt sourdough bread. Why spelt behaves differently than wheat, how to handle its fragile gluten, and a reliable Dinkelbrot recipe with Austrian flour types.
Spelt — Dinkel in German — is one of the most popular bread grains in Austria and across the German-speaking world. Walk through any Austrian supermarket and you will find Dinkelbrot on every shelf, Dinkelmehl in every baking aisle, and spelt-based products marketed as the wholesome, digestible alternative to conventional wheat. Austrians love this grain, and they have been baking with it for centuries.
But spelt is not wheat with a different name. It is a related grain that looks similar on paper — higher protein content, similar appearance, compatible with sourdough — and then behaves completely differently the moment you start working with it. The gluten in spelt is weaker and more fragile than wheat gluten. It develops quickly but breaks down easily. It absorbs less water. It punishes over-mixing and aggressive handling in ways that wheat forgives.
This distinction matters enormously for sourdough bakers. If you apply your wheat sourdough technique to spelt flour without adjusting your approach, you will likely end up with a flat, dense loaf and wonder what went wrong. The flour did not fail you — the technique was wrong for the grain.
This guide explains the science of spelt gluten, how to adjust your entire approach for this grain, and provides a reliable Dinkelbrot recipe with Austrian flour types that produces a beautifully risen loaf with a tender, flavorful crumb.
Why Spelt Is Not Just Another Wheat
Spelt (Triticum spelta) and common wheat (Triticum aestivum) are both members of the Triticum genus. They share a common ancestor and can even be crossbred. But the differences in their protein structure create fundamentally different baking behavior.
Higher Protein, Weaker Gluten
This is the fact that confuses most bakers when they first encounter spelt. Spelt flour typically has 12-15% protein — often higher than bread flour. Logically, you would expect stronger gluten, more structure, and better rise. The opposite happens.
Spelt's gluten proteins — gliadin and glutenin, the same two families found in wheat — form a network that is more extensible but less elastic than wheat gluten. In practical terms, this means spelt dough stretches easily but does not snap back. It lacks the rubbery resilience that gives wheat dough its ability to trap gas under pressure during fermentation and oven spring.
Why Fragile Gluten Changes Everything
The fragility of spelt gluten has cascading consequences for every step of the baking process:
Mixing: Spelt gluten develops fast — often in half the time wheat takes — but continuing to mix past the peak breaks the network down. Over-mixed spelt dough becomes slack, sticky, and loses its ability to hold shape. With wheat, you have a wide window between "fully developed" and "over-mixed." With spelt, that window is narrow.
Fermentation: A long, slow bulk fermentation — the standard for wheat sourdough — gives the acids in the sourdough more time to weaken the already-fragile gluten. Spelt benefits from shorter bulk times. If your wheat sourdough routine includes 5-6 hours of bulk fermentation with multiple sets of stretch-and-folds, that timeline will over-ferment spelt.
Folding: Aggressive stretch-and-folds stress the gluten network. Wheat recovers from this stress and actually becomes stronger through it. Spelt does not recover as well. Gentle coil folds are preferred — they redistribute the dough and build some tension without the stretching force that can tear spelt's weaker gluten bonds.
Hydration: Spelt absorbs approximately 5% less water than wheat flour of equivalent extraction. If your wheat bread runs at 75% hydration, start your spelt bread at 68-70%. The lower water absorption, combined with the weaker gluten, means high-hydration spelt doughs spread rather than rise.
Shaping: Spelt dough tears more easily during shaping. Be deliberate but gentle. Tight shaping is still necessary for surface tension, but the motions should be smooth, not forceful.
Austrian Spelt Flour Types
Austria has a strong spelt tradition, and Austrian mills produce specific spelt flour types that are widely available.
| Austrian Type | Extraction | Roughly Equivalent To | Best For |
|---|---|---|---|
| Dinkelmehl 700 | Medium (like W700 wheat) | German Dinkelmehl 630 | All-purpose spelt baking, Dinkelbrot |
| Dinkelmehl 1500 | High extraction | German Dinkelmehl 1050 | Heartier spelt breads, added flavor |
| Dinkelvollkornmehl | Whole grain | Whole spelt flour | Dense, nutty loaves, mixed into other flours |
Dinkelmehl 700 is the workhorse spelt flour in Austria and the one this recipe uses. It is a medium-extraction flour — not white, not whole grain — with good baking characteristics and enough bran content to give the bread flavor and color without making it heavy.
If you are outside Austria, look for "light spelt flour" or "white spelt flour" and check the protein content (should be 11-14%). Whole spelt flour is not a direct substitute — it absorbs significantly more water and produces a denser result. You can mix whole spelt with light spelt (roughly 30/70) for a heartier loaf that still rises well.
The Recipe
This Dinkelbrot produces one medium loaf (~850g baked weight) using primarily spelt flour with a small addition of wheat for structural support. It has a tender, moderately open crumb with a warm, nutty flavor that is distinctly different from wheat sourdough.
Spelt Sourdough (Dinkelsauerteig)
Build this the evening before bake day. You can use either a wheat or spelt sourdough starter — both work. If you maintain a wheat starter, simply use it as-is. The levain build itself uses spelt flour, which gives the bread its spelt character.
| Ingredient | Weight | Notes |
|---|---|---|
| Active sourdough starter (wheat or spelt) | 20g | At or near peak activity |
| Spelt flour (Dinkelmehl 700) | 80g | |
| Water (room temperature, ~22°C / 72°F) | 80g |
Mix in a jar, cover, and leave at room temperature for 8-10 hours (overnight). It should be domed, bubbly, and smell mildly tangy — not as aggressively sour as a rye sourdough, but clearly active.
Main Dough
| Ingredient | Weight | Baker's % |
|---|---|---|
| Spelt flour (Dinkelmehl 700) | 370g | 82% (of total flour) |
| Wheat bread flour (W700 / Type 550) | 80g | 18% |
| Spelt sourdough (all of the above) | 180g | Contains spelt flour from the levain |
| Water (cool, ~22°C / 72°F) | 270g | |
| Fine salt | 10g | 2% of total flour |
| Honey or malt syrup (optional) | 10g | Feeds the yeast, adds subtle sweetness |
Total flour: ~530g (450g spelt + 80g wheat = 85% spelt, 15% wheat) Total water: ~350g (80g from levain + 270g in main dough) Overall hydration: ~66% Spelt percentage: 85%
Baker's Percentages Breakdown
| Component | Baker's % (of total flour) |
|---|---|
| Total spelt flour | 85% |
| Total wheat flour | 18% |
| Total water | 66% |
| Salt | 2% |
| Starter (inoculation) | ~4% |
The 15-18% wheat flour is a structural safety net. The wheat gluten reinforces the spelt gluten network, giving the loaf more resilience during fermentation and oven spring. You can go 100% spelt, but the margin for error shrinks significantly. For your first spelt loaf, include the wheat.

Step-by-Step Method
Step 1: Build the Spelt Sourdough (Evening Before)
Combine 20g of active starter with 80g Dinkelmehl 700 and 80g room-temperature water. Mix until smooth. Cover and leave overnight at 20-24°C.
Spelt sourdough ferments faster than wheat sourdough at the same temperature. Check it after 8 hours. If it has more than doubled and is starting to collapse, it is past peak — usable but slightly weaker. Ideally, catch it at or just past the dome stage: fully risen, bubbly throughout, holding its shape.
Tip: Use cool water (20-22°C) for the levain build. This slows fermentation slightly and gives you more time in the morning before it over-ripens. With warm water and a warm kitchen, spelt levain can peak in as little as 6 hours.
Step 2: Mix the Dough
In your mixing bowl, combine the ripe spelt sourdough, 370g Dinkelmehl 700, 80g wheat bread flour, and 270g cool water. Mix by hand until no dry flour remains — this should take only 1-2 minutes. Do not knead. The dough will be shaggy and rough.
Hold back the salt. You will add it after the autolyse.
Step 3: Autolyse (20 Minutes)
Cover the bowl and let the dough rest for 20 minutes. During this time, the flour fully hydrates and the gluten begins to develop passively — without any mechanical input from you. This passive development is especially valuable for spelt because it builds gluten structure without the risk of over-working.
After 20 minutes, the dough should feel noticeably smoother and more cohesive than when you first mixed it.
Step 4: Add Salt and Brief Mix
Sprinkle the 10g of salt (and honey/malt, if using) over the dough. Fold the dough over itself a few times, then use the pinch-and-fold technique: pinch the dough between your thumb and fingers to distribute the salt, fold, rotate the bowl, repeat. This should take 2-3 minutes.
Important: Do not mix aggressively. Do not knead. The goal is to incorporate the salt uniformly, not to develop the gluten further. With wheat, you might slap-and-fold at this stage for 5-10 minutes. With spelt, that would be too much.
The dough should feel slightly sticky but smooth, with moderate elasticity. It will not be as strong or bouncy as wheat dough at the same stage — that is normal for spelt.
Step 5: Bulk Fermentation (2.5-3.5 Hours)
Bulk fermentation for spelt is shorter than for wheat. Where a wheat sourdough might bulk for 4-6 hours, spelt should bulk for 2.5-3.5 hours at 22-24°C. The faster timeline reflects two things: spelt ferments faster because its simpler starch structure is more accessible to the sourdough microbes, and the fragile gluten cannot withstand prolonged acid exposure.
Perform 3 sets of coil folds during the first 90 minutes of bulk, spaced 30 minutes apart:
Coil folds (not stretch-and-folds):
- Wet your hands lightly
- Slide your hands under the dough from the sides
- Lift the center of the dough up, letting the edges fold underneath by gravity
- Rotate the bowl 90 degrees and repeat
- That is one set — two lifts, one set
Coil folds are gentler than stretch-and-folds because you are not pulling the dough outward — gravity does the folding. This is exactly what spelt's fragile gluten needs: organization and tension without aggressive stretching.
After the third set of coil folds (at the 90-minute mark), leave the dough undisturbed for the remaining 1-2 hours of bulk.
When is bulk done? The dough should have risen by 40-60% (not doubled — spelt does not rise as aggressively as wheat during bulk). It should feel airy and puffy when you tilt the bowl, with visible bubbles along the sides and bottom. The surface should be slightly domed, smooth, and jiggle when you nudge the bowl.
Do not push bulk too far. Over-fermented spelt dough degrades rapidly. Once the gluten starts breaking down, the dough becomes slack, sticky, and impossible to shape well. If in doubt, end bulk earlier rather than later — you can compensate with a longer cold retard.
Step 6: Pre-shape
Gently turn the dough out onto a lightly floured surface. Using a bench scraper and one floured hand, perform a gentle pre-shape: tuck the edges underneath to form a rough round. The motions should be smooth and quick — do not drag the dough or apply heavy pressure.
Let the pre-shaped round rest on the counter for 15-20 minutes. The gluten will relax, making final shaping easier. If the dough spreads flat during this rest, your bulk fermentation may have gone too far — proceed with final shaping anyway, but note the issue for next time.
Step 7: Final Shape
Lightly flour the top of the pre-shaped dough and flip it over (smooth side down). Perform a final shape:
For a boule:
- Fold the top third down to the center
- Fold the bottom third up over it
- Fold the left side to center, then the right side
- Flip the whole package over (seam side down)
- Using the bench scraper and your hand, gently drag the round toward you on the unfloured counter to build surface tension
- The bottom should catch slightly on the counter surface, tightening the outer skin
For a batard:
- Fold the top edge down two-thirds
- Fold the bottom edge up to meet it
- Roll the seam closed, sealing gently with your fingertips
- Rock the batard gently to even out the shape
Be deliberate but not aggressive. Spelt dough tears more easily than wheat dough. If you see the surface tearing, stop — you have enough tension. Better a slightly under-shaped loaf that holds together than a torn one that degasses.
Step 8: Cold Retard
Place the shaped dough seam-side up in a well-floured banneton (rice flour works best for preventing sticking). Cover with plastic wrap or a shower cap.
Refrigerate for 4-18 hours. The cold retard firms the dough, develops flavor, and makes the loaf much easier to score. Spelt especially benefits from cold retarding because the cold stiffens the weak gluten, giving the dough more structural integrity than it has at room temperature.
A minimum of 4 hours is needed for the cold to penetrate fully. Overnight (12-16 hours) is ideal. You can push to 18 hours, but beyond that the acid continues to degrade the spelt gluten even at fridge temperatures.
Step 9: Preheat and Bake
Preheat your oven to 240°C (465°F) with the Dutch oven inside for at least 45 minutes.
Remove the dough from the fridge. Turn it out onto parchment paper. The cold dough should hold its shape well and feel firm to the touch.
Score: Use a sharp lame or razor blade. A single confident slash works well for spelt — keep it simple. Cut about 8 mm deep at a 30-45 degree angle. Spelt dough does not produce ears as dramatically as wheat (the weaker gluten cannot sustain the same lift), but you will still get a nice opening.
Lower the parchment with the dough into the preheated Dutch oven. Cover with the lid.
Bake:
- 20 minutes covered at 240°C (steam phase)
- Remove lid, reduce temperature to 220°C (430°F)
- 20-25 minutes uncovered until the crust is golden brown
Spelt bread browns faster than wheat bread due to its higher sugar content. Watch the color in the last 10 minutes — if it is getting very dark, reduce the temperature to 210°C.
Internal temperature: 93-95°C (200-203°F) in the center, same as wheat bread.
Step 10: Cool
Place the loaf on a wire rack and allow it to cool for at least 1-2 hours before slicing. Spelt bread does not require the extended cooling period that rye bread demands, but cutting too early will compress the still-setting crumb and release steam that the bread needs to retain for moisture.
The Spelt Flavor Profile
Well-made Dinkelbrot has a flavor that is distinctly different from wheat sourdough — and many people prefer it.
Nutty and warm. Spelt has a naturally nutty, slightly sweet flavor that wheat lacks. This comes from spelt's different starch and sugar composition. Even a mild sourdough fermentation brings out these notes.
Less sour. Because spelt benefits from shorter fermentation times, the bread typically develops less acidity than a long-fermented wheat sourdough. The result is a milder, more approachable sourness that appeals to people who find wheat sourdough too tangy.
Tender crumb. The weaker gluten produces a softer, more tender crumb than wheat bread at the same hydration. Spelt bread has a melt-in-your-mouth quality that makes it wonderful for sandwiches and toast.
Better digestibility (anecdotally). Many people who experience discomfort with modern wheat report that spelt is easier on their digestion. The scientific evidence for this is mixed, but the shorter fermentation times mean less acid, and the different protein structure may genuinely be easier for some people to tolerate. Spelt still contains gluten and is not safe for people with celiac disease.
Common Spelt Mistakes and How to Avoid Them
| Mistake | What Happens | The Fix |
|---|---|---|
| Using wheat hydration levels (75%+) | Dough is slack, spreads flat, poor oven spring | Reduce hydration to 65-68% for spelt |
| Over-mixing or kneading | Gluten breaks down, dough becomes sticky and weak | Mix only until combined (2-3 minutes), rely on autolyse and gentle folds |
| Long bulk fermentation (5+ hours) | Acid degrades fragile gluten, dough loses structure | Shorten bulk to 2.5-3.5 hours at room temperature |
| Aggressive stretch-and-folds | Tears the gluten network | Use coil folds instead — gentler, gravity-driven |
| Skipping cold retard | Dough is too soft to score and shape cleanly | Always cold retard spelt dough (minimum 4 hours) |
| Over-proofing | Spelt collapses faster than wheat once over-proofed | End bulk at 40-60% rise, not doubled |
| Using whole spelt flour only | Too much bran, crumb is very dense | Use Dinkelmehl 700 (medium extraction) or mix with 15-20% wheat flour |
Variations
100% Spelt (No Wheat)
Omit the 80g of wheat flour and replace it with additional Dinkelmehl 700. This gives you a pure spelt loaf, but reduce the hydration by another 2-3% (subtract about 15g of water) and be even more gentle with handling. The margin for error is slim — fermentation timing, fold technique, and shaping all need to be precise. Worth trying once you have a few successful spelt loaves under your belt.
Spelt with Seeds
Add 60-80g of a seed mix (sunflower, pumpkin, sesame, flax) during the first coil fold. The seeds add texture, nutrition, and visual appeal. Lightly toast them first for deeper flavor. No hydration adjustment needed — the seeds absorb minimal water in the short bulk time.
Honey-Spelt Sourdough
Increase the honey to 25-30g for a subtly sweet loaf that is extraordinary when toasted. The honey also feeds the yeast, giving a slightly better rise. This variation makes a wonderful breakfast bread with butter and jam.
Spelt-Rye Blend
Replace 20-30% of the spelt flour with rye flour (R960) for a heartier bread with more complexity. Use the rye sourdough method from the Bauernbrot recipe for the rye portion, and handle the rest as per this recipe. The result is a dense, flavorful loaf that combines the nuttiness of spelt with the tang of rye.

See the sourdough app →Frequently Asked Questions
Why does my spelt bread come out flat? The three most common causes: hydration too high (spelt cannot support the same water content as wheat — reduce to 65-68%), over-fermented during bulk (shorten to 2.5-3.5 hours), or over-handled during mixing and folding (switch to gentle coil folds, mix only until combined). Spelt's fragile gluten collapses under conditions that wheat tolerates easily.
Can I use my regular wheat sourdough starter for spelt bread? Yes. You do not need to convert your starter to spelt. The levain build uses spelt flour, which introduces spelt character to the bread. Your wheat starter provides the microbial culture; the flour you feed it for the levain determines the bread's flavor. Some bakers maintain a separate spelt starter, but it is not necessary.
How much less water does spelt need compared to wheat? As a general rule, reduce hydration by about 5 percentage points. If your wheat recipe runs at 75%, start your spelt version at 68-70%. If it runs at 72%, try 66-68%. The exact amount depends on the specific flour — whole spelt absorbs more than light spelt — so adjust based on how the dough feels. It should be slightly tacky but manageable, not wet and slack.
Why are coil folds better than stretch-and-folds for spelt? Stretch-and-folds involve pulling the dough outward, which applies direct tensile stress to the gluten network. Wheat gluten is elastic enough to handle this. Spelt gluten is more extensible but less elastic — it stretches but does not snap back — and the pulling motion can tear the network rather than strengthen it. Coil folds use gravity: you lift the center and let the sides fold under their own weight. Same organizational benefit, much less mechanical stress.
How do I know when bulk fermentation is done for spelt? Look for a 40-60% rise from the starting level (mark the container with tape or a rubber band). The dough should feel puffy and airy, jiggle when you move the bowl, and show bubbles along the sides. Do not wait for it to double — by the time spelt dough doubles, the gluten is often already compromised. When in doubt, end bulk early and rely on the cold retard for continued flavor development.
What is Dinkelmehl 700 and can I substitute it? Dinkelmehl 700 is an Austrian medium-extraction spelt flour with an ash content of ~700mg per 100g. It is roughly equivalent to German Dinkelmehl 630. Outside the German-speaking world, "light spelt flour" or "white spelt flour" is the closest match. Whole spelt flour is not a substitute — it is much denser and absorbs more water. If you can only find whole spelt, mix it with all-purpose wheat flour (roughly 70% whole spelt, 30% AP wheat) to approximate the baking behavior.
Does spelt bread go stale faster than wheat bread? Spelt bread can dry out slightly faster than wheat bread because spelt's starch retrogrades at a similar rate but the lower hydration means less moisture to begin with. Adding 10g of honey or malt syrup helps with moisture retention. Proper storage in a bread box or cloth also helps. Spelt bread freezes excellently — slice before freezing for convenience.
Can I make spelt bread without any wheat flour at all? Yes, but it is more challenging. Without wheat's stronger gluten as a structural backbone, the loaf will be more fragile, rise less, and have a denser crumb. Reduce hydration by another 2-3%, handle the dough even more gently, keep bulk fermentation short, and accept that the crumb will be tighter than a wheat-spelt blend. Many excellent 100% spelt loaves exist — they just require more precision.
Is spelt bread healthier than wheat bread? Spelt contains slightly more protein, more B vitamins, and more minerals (particularly zinc and manganese) than common wheat. It also has a different gluten structure that some people find easier to digest. However, spelt still contains gluten and is not suitable for people with celiac disease. The shorter fermentation times used for spelt may also mean less phytic acid breakdown compared to a long-fermented wheat sourdough. "Healthier" depends on what metric you are optimizing for.
Why does my spelt dough become sticky and unmanageable during bulk? This is almost always a sign of over-fermentation or over-handling. The gluten has broken down. Once spelt dough crosses this threshold, there is no recovering it — you cannot knead or fold it back to life the way you sometimes can with wheat. Shorten your bulk time, use fewer and gentler folds, and watch for the 40-60% rise mark. If your kitchen is warm (above 25°C), you may need to reduce bulk to under 2.5 hours.
What scoring pattern works best for spelt? Keep it simple. A single slash or a cross works well. Spelt's weaker gluten produces more modest oven spring than wheat, so elaborate patterns with many cuts can deflate the loaf. One confident cut, 8mm deep, is enough to guide the expansion. Score straight from the fridge — cold spelt dough holds its shape for scoring much better than room-temperature spelt dough.
Can I do a same-day bake without cold retarding spelt? You can, but the results will be better with a cold retard. At room temperature, spelt dough is soft and difficult to score cleanly. The cold firms up the weak gluten and makes the dough far more manageable. If you must bake same-day, proof the shaped dough at room temperature for 45-60 minutes (watching carefully for over-proofing), then bake immediately. Skip elaborate scoring — a simple cross is enough.
