Anyone wanting to bake bread soon faces the question: which flour type suits my recipe? The number on the bag is more than just a classification — it affects dough handling, flavour and appearance. Here you’ll find a compact overview and practical guidance.
What does the type designation mean?
The flour type indicates the mineral content of a flour. It relates to the amount of the grain’s outer layers that remain in the flour. In short: the higher the type number, the more mineral-rich components from the outer layers are present — and the darker and more flavourful the bread usually is. Light types consist mainly of the endosperm and therefore produce milder, paler loaves.
Important: the type is not an indication of particle size (fineness). Finely or coarsely milled flour can carry the same type number; the type does not describe how finely the flour was milled.
Wheat and spelt flours at a glance
Wheat flour (selection of common types)
- Type 405: Very pale flour, classic for pastries and cakes; generally used in mixes for bread.
- Type 550: Popular for light loaves and rolls; balanced flavour and reliable dough performance.
- Type 812: Moderate strength and colour; for slightly heartier yet still pale loaves (availability varies regionally).
- Type 1050: Darker and more flavourful; ideal for mixed loaves and more rustic crusts.
- Wholemeal flour: No type designation; contains all parts of the grain.
Spelt flour (selection of common types)
- Type 630: Light spelt flour; for fine pastries, light loaves and rolls.
- Type 812: Moderate strength; for somewhat heartier spelt breads (available in some regions).
- Type 1050: Noticeably more flavourful; for rustic spelt breads and blends.
- Wholemeal flour: No type designation; the whole grain.
What the type means for the dough
In practice, flours with a higher type number often absorb more water. They tend to bring stronger flavours and a darker crumb. Light types produce milder flavours and a light, fine-textured crumb. How a flour behaves also depends on the mill, the harvest and protein characteristics — the type alone does not determine the final bake.
Practical: choosing the right flour type
- Light breads and rolls: Wheat 550 or spelt 630 are a good starting point.
- Heartier mixed breads: Wheat/spelt 1050 alone or mixed with lighter types or with a proportion of wholemeal.
- To increase wholemeal proportion: Mix gradually and adjust the water amount accordingly, as wholemeal usually absorbs more water.
- Test and record: Add water little by little, monitor the dough’s feel and adjust baking times and temperatures to suit your oven.
Tip for the wood-fired oven: Medium-strength flours (e.g. 550/1050 or 630/1050) often deliver a good balance of oven spring, crust and flavour under intense heat. With very dark flours, watch dough yield and proofing so the crumb stays moist and open.
Common misconceptions
- “The lower the type, the finer the grind”: The type measures mineral content, not milling fineness.
- “Same type = same result”: Mills, harvests and protein characteristics vary. Always adapt recipes to the specific flour you are using.
A brief note on rye
Rye flour has its own type designations and behaves differently from wheat and spelt in baking. Loaves are often managed with sourdough to achieve an open crumb and balanced flavour. If you’re new to rye, start by increasing rye proportions gradually through mixed breads.
Conclusion
The type number indicates a flour’s mineral content — not its fineness. Light types lend themselves to mild, pale breads; higher types and wholemeal bring more flavour and colour. By mixing thoughtfully and adjusting hydration, you’ll quickly find the flour combination that suits your favourite loaf and your oven.
