Short answer
Usually under-proving, not enough kneading, or plain flour instead of strong bread flour. A dense loaf with a tight even crumb means the gluten never developed; one that rose and collapsed means it over-proved.
An open airy crumb needs two things: gluten strong enough to trap gas, and enough time for the yeast to produce it. Density is nearly always one of those failing, and the pattern of the crumb tells you which.
What you'll need
- Strong bread flour
- Kitchen scales (optional)
- Time (optional)
Step by step
- Check you used strong bread flour.Plain flour has too little protein to build the gluten structure that traps gas. It is the most common single cause of a dense loaf.
- Check the dough was kneaded enough.Ten minutes by hand, or until it passes the windowpane test — a small piece stretched thin should go translucent without tearing straight away.
- Check it proved long enough.Until roughly doubled, judged by size not time. A cold kitchen can double the proving time and under-proved dough bakes dense.
- Check the dough was not too dry.Adding flour during kneading because it felt sticky is a very common cause. Wetter dough gives a more open crumb; oil the surface instead of flouring it.
- Consider whether it over-proved instead.Dough that rose beautifully and then collapsed in the oven went too far. The gluten stretched past what it could hold.
- Check the shaping created surface tension.Shaping should pull the surface taut. A loosely shaped loaf spreads sideways rather than rising.
- Check the oven was hot enough.Bread needs a hot oven for oven spring — the final rapid rise. A cool oven gives a dense, pale loaf.
- Consider the flour type if using wholemeal or rye.Both give denser loaves by nature. Mixing them with white bread flour lightens the result considerably.
Tips
- Steam in the oven for the first ten minutes — a tray of boiling water on the floor of the oven — improves oven spring noticeably.
- A longer, cooler prove gives better flavour and usually a better crumb than a fast warm one.
- Weigh the water as well as the flour. Hydration percentage is what determines crumb structure, and cups are too imprecise for bread.
Common mistakes
- Adding flour because the dough is sticky — Wetter dough gives a more open crumb. Sticky is normal early in kneading; oil the surface rather than adding flour.
- Using plain flour for bread — There is not enough protein to build gluten, so the loaf cannot hold gas and bakes dense.
- Proving by the clock — Kitchen temperature changes proving time enormously. Judge by size and the poke test instead.
Questions people ask
Why is my homemade bread so heavy?
Most often plain flour instead of strong bread flour, not enough kneading, or under-proving. A tight even crumb points at gluten; a collapsed loaf points at over-proving.
How do I get a more open crumb in bread?
Use a wetter dough, develop the gluten fully, prove until properly doubled, shape with surface tension, and bake in a hot oven with steam for the first ten minutes.
