When kneading dough are you frequently asking yourself “Is it ready yet”? If so, in this article I’ll share how to know when to end kneading. We do this by feeling the dough and using “The Windowpane Test”. It’s a great way to know when your dough was been kneaded enough and can also show you when to end the first rise.
Why kneading is important for the gluten structure?
Kneading forms the gluten matrix in the dough. It needs this structure to retain gas during the final rise. A well-worked dough develops gluten that’s strong enough to stretch thinly without tearing. This forms a network of strands that retain gas.
The effect of oxygen in bread dough?
Kneading also incorporates oxygen into the dough. The yeast uses oxygen for respiration, which is different to fermentation.

During respiration, the yeast uses oxygen to provide carbon dioxide gas. When the yeast ferments anaerobically, it produces C02 and ethanol.
So for light and fluffy bread, we want to encourage kneading. This provides a lighter flavour and a better rise in the bread. A common cause of dense bread is not working the dough on the table or mixer enough.
Problems with under kneading
Some bakers don’t knead their dough for long enough or don’t use a method that kneads dough effectively. See my post dedicated to how to knead dough to learn more about the latter.
Common signs of under kneaded dough are:
- The bread takes too long to rise
- The gluten structure (crumb) is dense
- The bread explodes from the sides or base in the oven
In this post, we are going to cover how to tell when to stop kneading.
There are two methods, “The feel the dough test”, and “The windowpane test”.
The feel the dough test
The easiest method is to use the relax and feel test.
- Let the dough relax on the table for one minute.
- Break away a small piece and roll it into a ball.
- Play with the ball in your fingers.
What does a well-kneaded dough look like?
- Feels slightly gassy.
- Creamy white colour.
- Smooth surface texture.
- Elastic enough to support itself – it springs back.
- Nice, rounded smell.
- A sheen of natural oils coating the surface.

Signs of under kneading
If your dough lacks elasticity, tears easily when stretched and doesn’t appear smooth then it is under kneaded. Knead the dough for a few more minutes and check again.
How to do the windowpane test
A windowpane test reveals the strength of the gluten. It’s the best way to see how well gluten has developed.
- Let the dough relax for a minute.
- Gently tare off a piece.
- Pinch a side in each hand and stretch it gently with your fingers
- Hold it up in front of you and use the table below to rate it.
Windowpane test results table
Dough breaks when lightly stretched.
|Dough has a small amount of stretch (1-2 cm) before it tears.|
|Stretches 2-3 cm before it tears.|
Stretches thin to 5-8cm without tearing. Remains opaque when held up against a light.
Stretches thinly and allows light to shine through when held up.
Interpreting the windowpane results
As the dough is kneaded it will pass through each of the stages shown in the table. Working the dough further will continue to develop the gluten so that it passes the next grade.
Most home bakers will use a bulk fermentation period to allow the dough to develop naturally.
See a timeline of how kneading affects the length of bulk fermentation required in the proofing guide table.
How to pass the windowpane test
The simple solution is to knead for longer! Though this is hard work when kneading by hand. Most home bakers will allow the dough to rest during bulk fermentation to develop naturally. Here the gluten will continue to develop whilst oxygenation is lowered. This means the dough benefits from organic acids which will generate an improved gluten structure.
Here are a few tips in order to make your dough pass the test:
- Add prefermented flour.
- Start with an autolyse to hydrate the flour.
- Use a slow technique at first to help the flour hydrate.
- Follow a proven kneading technique or use a quality dough mixer.
- If using a no-knead recipe, use stretch and folds and a long bulk fermentation time at a cool temperature.
- Bulk ferment with stretch and folds.
- Delay fats and sweeteners till the end of mixing where possible.
- Measure your ingredients with scales for accurate measurements.
Can I use the windowpane test for sourdough?
Yes! Slow rising doughs like sourdough should only be kneaded lightly. As the gluten is left to develop during the first rise it continues to strengthen and bond. It will also absorb oxygen from the surrounding area. This, compiled with the masses of oxygen incorporated during kneading, can lead to over-oxygenation. This ruins the flavour and gas retaining properties of the flour.
For sourdough and other artisan bread, lightly knead and use the windowpane test to check the development of the dough during bulk fermentation. The trick is for the gluten to develop at the same point that the dough doubles in size!
What does over kneaded bread dough look like?
It’s not common to over-knead dough by hand, but it can happen in a dough mixer. If your bread dough is sticky, warm, gassy and lacks strength it is over kneaded.
