I do not know who first suggested feeding a sourdough starter with slightly more flour than water, but whoever you are — thank you.
Genuinely.
For a long time, I fed my starter with equal parts flour and water. It worked. It rose. It baked bread. Nothing was technically wrong.
But then I tried a small change.
Instead of feeding 1:5:5, I fed my starter at 1:5:4.
That means:
5g starter
25g flour
20g water
Same starter. Same flour. Same routine. Just slightly less water.
And somehow, that small adjustment changed everything.
The starter felt stronger. The peak held longer. The dough made from it behaved better during bulk fermentation, shaped more smoothly, and baked with better oven spring.
I was not expecting such a visible difference from one small tweak.
But now I understand why it worked.
What Is A 1:5:4 Starter Feeding?
A 1:5:4 feeding ratio means:
1 part starter
5 parts flour
4 parts water
So if you start with 5g of starter, you feed it with 25g flour and 20g water.
If you start with 10g starter, you feed it with:
10g starter
50g flour
40g water
The important difference is that the flour and water are not equal.
A classic 1:5:5 feeding uses equal flour and water, which creates a 100% hydration starter. A 1:5:4 feeding uses slightly less water, which makes the starter thicker and stiffer.
It is not a dry stiff starter like Pasta Madre, but it is firmer than a regular liquid starter.
That slight stiffness is where the magic happens.
Why Slightly Less Water Makes A Difference
Hydration changes how a starter behaves.
A wetter starter ferments more freely. Water allows acids, enzymes, sugars, yeast, and bacteria to move easily through the mixture. That can make the starter rise quickly, bubble fast, and collapse sooner.
A slightly stiffer starter moves more slowly and holds structure better.
Because there is less water, the starter forms a tighter internal matrix. That structure helps trap gas instead of letting it escape too quickly.
The result is often:
A stronger dome
A longer peak window
Better gas retention
Less collapse
A more stable starter
A slightly more controlled fermentation
That is exactly what I noticed.
The starter did not just look active. It looked supported.
The Difference Between 1:5:5 And 1:5:4
A 1:5:5 starter is equal parts flour and water.
It is looser, easier to stir, and very common for everyday maintenance. It works beautifully for many bakers.
A 1:5:4 starter has the same amount of flour but less water.
That means it is thicker, more paste-like, and slightly more structured.
The difference may seem tiny, but in the jar it can be very visible.
With 1:5:5, the starter may rise well but soften faster after peak.
With 1:5:4, the starter may rise with a stronger dome and hold that peak longer.
That longer peak window is what makes it so practical. You are not rushing to catch the starter at the exact perfect minute. It gives you more breathing room.
Why A Longer Peak Window Matters
Missing your starter’s peak is one of the most frustrating parts of sourdough.
You feed it, it rises beautifully, and then by the time you are ready to mix dough, it has already fallen.
A slightly stiffer starter can help with that.
Because it holds gas better and collapses more slowly, the usable window often feels wider. That means you can use the starter when it is still strong instead of constantly trying to catch a fast-moving peak.
This is especially helpful if:
Your kitchen is warm
Your starter usually peaks too fast
You feed before bed
You bake around a busy schedule
You want more flexibility before mixing dough
A longer peak window makes sourdough feel less stressful.
Why The Dough Behaves Better
The change does not stop in the jar.
A slightly stiffer, stronger starter can affect the dough too.
When the starter is balanced and holding gas well, it brings better fermentation strength into the dough. The dough may feel more elastic, more organized, and less overly sticky during bulk fermentation.
That is what I noticed immediately.
The dough built from the 1:5:4 starter felt easier to read. It developed strength. It held gas well. It moved through bulk fermentation more cleanly.
During shaping, it felt more cooperative.
In the oven, it had better spring.
This does not mean 1:5:4 is magic. You still need good flour, proper fermentation, strong shaping, and a hot bake.
But the starter is the foundation.
And when the foundation improves, the whole loaf improves.
Why Gas Retention Is The Real Secret
A starter does not rise just because it makes gas.
It rises because it holds gas.
That is the part many bakers miss.
A very wet or weakened starter can produce plenty of bubbles, but if the structure is too loose, gas escapes instead of lifting the starter. You may see foam on top but not much strong rise.
A slightly stiffer starter creates more resistance. The gas stays trapped longer, and the starter rises with more structure.
That is why the dome matters.
A strong dome means gas is being produced and supported.
That support is what you want to carry into your bread dough.
Does 1:5:4 Make Your Starter Less Sour?
It can help create a more balanced starter.
A slightly stiffer starter often ferments more slowly and may build acidity differently than a wetter starter. Because it holds structure longer and does not collapse as quickly, it can feel less sharp when used at the right time.
That said, sourness still depends on many factors:
Temperature
Flour type
How long it ferments
How often you feed
How far past peak it goes
How much whole grain flour you use
The 1:5:4 ratio does not remove sourness completely, but it can help make the starter feel more controlled and less aggressively acidic.
How To Feed Your Starter At 1:5:4
The method is simple.
Start with a small amount of active starter.
Add 5 times that amount in flour.
Add 4 times that amount in water.
Mix until fully combined. The texture will be thicker than a regular 100% hydration starter. It should feel like a thick paste, not a pourable batter.
Scrape down the sides of the jar, mark the level with a rubber band, and cover loosely.
Let it rise at room temperature until it reaches peak.
Example Small Feed
5g starter
25g flour
20g water
Example Medium Feed
10g starter
50g flour
40g water
Example Larger Feed
20g starter
100g flour
80g water
What The Texture Should Look Like
A 1:5:4 starter should be thick but mixable.
It should not be dry and crumbly. It should not be runny.
Think thick paste, soft dough, or very thick batter.
Right after feeding, it may look dense and stiff. As it ferments, it should expand, bubble, and form a smooth dome.
When ready, it may look less loose than your usual starter, but it should feel alive. If you stir it, it should feel airy inside.
When To Use It For Bread
Use the 1:5:4 starter when it is near peak or at peak.
Look for:
A clear rise above the starting level
Bubbles throughout the jar
A smooth dome
A pleasant tangy smell
A thick, airy texture
No full collapse yet
This is when the starter has strength and structure.
If it has fallen slightly, it may still be usable. If it has collapsed completely and smells very sharp, feed it again before baking.
Can You Put The Rest Back In The Fridge?
Yes.
One of the reasons I like this method is that the starter feels stable after feeding. Once I use what I need for bread, the rest can go back into the fridge.
Because the starter is slightly thicker, it often holds up well during storage.
If you bake often, you can keep using this as your regular maintenance ratio.
If you bake less often, feed it, let it begin showing activity, then refrigerate it.
When you want to bake again, take it out and refresh it.
Who Should Try A 1:5:4 Feeding?
This ratio is especially helpful if your starter:
Peaks too quickly
Collapses fast
Looks foamy but weak
Feels runny after feeding
Becomes too acidic too quickly
Does not hold a dome
Makes dough that feels sticky or hard to manage
It is also helpful if you want more flexibility in timing.
If your current 1:5:5 starter works beautifully, you do not need to change anything. But if you are curious, this is a small experiment with potentially big results.
What To Watch For When You Try It
The first time you switch to 1:5:4, watch the starter closely.
Notice how long it takes to rise.
Notice whether the dome holds longer.
Notice if the smell changes.
Notice how the dough feels when you bake with it.
Notice whether your loaf has better oven spring.
Do not judge by one feeding only. Try it for a few cycles and see if the pattern improves.
Sourdough is about patterns, not one perfect moment.
Troubleshooting
My 1:5:4 Starter Feels Too Dry
Add a few extra grams of water next time. Different flours absorb water differently, so your starter may need a small adjustment.
My Starter Is Not Rising
It may be too cold, your starter may be weak, or the feeding ratio may be too high for its current strength. Keep it warmer or try 1:3:3 for a few feeds before returning to 1:5:4.
My Starter Still Collapses Quickly
Your kitchen may be warm, or your starter may be very active. Try using a higher ratio or refrigerating sooner after it starts rising.
My Dough Is Still Sticky
Starter hydration is only one piece. Sticky dough can also come from over-fermentation, weak flour, high hydration, or not enough gluten development.
FAQ
What Does 1:5:4 Mean In Sourdough Starter Feeding?
It means 1 part starter, 5 parts flour, and 4 parts water. For example, 5g starter, 25g flour, and 20g water.
Is 1:5:4 A Stiff Starter?
It is slightly stiffer than a regular 100% hydration starter, but not as stiff as Pasta Madre. It is more like a thick starter with better structure.
Why Use More Flour Than Water?
Using more flour than water creates a thicker starter that can hold gas better, form a stronger dome, and often keep a longer peak window.
Can I Use 1:5:4 Every Day?
Yes, if your starter responds well to it. Many bakers prefer a slightly stiffer starter for daily maintenance because it feels more stable.
Does A Stiffer Starter Make Better Bread?
It can help, especially if your current starter collapses quickly or feels too acidic. A stiffer starter may improve structure, timing, and dough behavior.
Can I Switch Back To 1:5:5?
Yes. Starter feeding is flexible. You can switch back anytime.
Should I Adjust My Bread Recipe If I Use 1:5:4 Starter?
For most recipes, the difference is small. If you are using a large amount of starter, you may need to slightly adjust water, but for typical home baking it usually works fine.
Conclusion
Sometimes the smallest sourdough tweak makes the biggest difference.
Switching from 1:5:5 to 1:5:4 may not sound dramatic, but that little bit less water can change how your starter behaves.
It can hold gas better.
It can build a stronger dome.
It can give you a longer peak window.
It can make the dough feel more stable.
It can improve the final loaf.
That does not mean every baker needs to switch.
But if your starter peaks too fast, collapses quickly, or feels too loose and unpredictable, a 1:5:4 feeding is absolutely worth trying.
Same starter.
Slightly less water.
Completely different feel.
Sometimes that is all it takes.
