At a Glance
Hartweizengrieß (durum wheat semolina) is the coarse, yellowish middlings from durum wheat milling. It has higher protein and gluten quality than common wheat but coarser granulation; prized for pasta, hearth breads and breads with a toothy crumb.
💡 Semolina is not a type number like German wheat/rye types; it refers to particle size and the durum wheat kernel. Protein is typically strong and amber color reflects carotenoids in durum.[1]
🛒 Recommended Products

Properties
| Particle size | Coarse to medium (0.3–1.0 mm) |
| Color | Yellow / amber |
| Protein quality | High gluten strength (elastic) — good for structure |
| Protein content | 12–14% (varies by mill) |
| Water absorption | Moderate-high (60–72%) depending on grind |
⚠️ Coarse semolina creates a gritty, open crumb and a firm crust; gluten from durum is strong but less extensible than common wheat — handle with slightly shorter mixing to avoid toughness.[1][2]
Best Uses
✓ Ideal for:
- • Rustic hearth breads with a coarse crumb
- • Mixed wheat-durum sourdoughs
- • Topping or dusting to prevent sticking
- • Flatbreads and pizza with a bite
✗ Not ideal for:
- • Very soft sandwich bread → Use fine all-purpose or bread flour
- • Delicate cake-like crumb → Use cake/pastry flour
Mixing recommendations:
Behavior in Dough
Consistency
Grittier feel and slightly drier surface compared to equivalent wheat doughs — this is NORMAL
Development
Gluten forms differently: strong but less stretchy — windowpane may be weak
Fermentation
Ferments comparably but may require slightly longer bulk to relax coarse particles
Sourdough required!
Semolina benefits from sourdough fermentation to develop flavor and improve crumb softness; acid also helps modify starches and enzyme activity when durum is blended with other flours[1]
Minimum: Even 10–20% starter in overall dough improves flavor and extensibility
Hydration
Recommended: Start with 60% hydration for 20–30% semolina blends; increase 2–5% for higher semolina ratios
Because semolina particles absorb water differently, allow a 20–30 minute rest after mixing (autolyse) so water equalizes.
Alternatives & Substitutes
Direct alternatives:
Finer grind than semolina; gives similar flavor with less grittiness
More extensible gluten, softer crumb — use when you want less chew
Less coarse, closer to durum flour in behavior

Where to Buy
🛒 Supermarket

- Italian specialty stores
🌿 Organic
- Natural food stores and local mills
🌾 Mills Online
💡 Buy from a reputable mill or recent packaging date — semolina's aroma fades over time. For starter work, keep a small portion of semolina in an airtight jar such as a [glass jar for starter](https://amzn.to/4pWAN8D) for feeding and storage.
Storage
Shelf life
6–9 months sealed at room temperature; 9–12 months refrigerated
Storage location
Cool, dry, dark. Airtight container limits rancidity.
⚠️ Semolina contains more lipids than soft wheat which can oxidize; refrigerate for longer storage and use a [digital kitchen scale](https://amzn.to/4pUMVHi) to portion small quantities accurately.
