Dough Not Rising? Why, and How to Fix It (Even in a Cold Kitchen)

PPin it

If your dough is sitting in the bowl doing nothing, it is usually not the recipe and it is not you. Most of the time it is temperature, and the rest of the time it is the yeast.

Most homes sit around 18 to 21°C (64 to 70°F) in winter. That feels fine to us, and it is cold for yeast. Cold flour, a cold bowl and a draught all stack on top of that.

I have proofed dough in cold home kitchens and in draughty commercial kitchens, and the fix is the same in both. Control the temperature instead of waiting and hoping.

Why Is My Dough Not Rising? The Six Usual Reasons

1. It is too cold. Below about 20°C (68°F) yeast works very slowly, and an hour or more gets added to a rise. The fix is a warm spot, and there are three below.
2. The yeast is old or was stored badly. Dried yeast keeps for months, but not for ever, and fresh yeast only lasts a week or two in the fridge. Test it before you blame anything else.
3. The water was the wrong temperature. Too hot and it kills the yeast. With active dry yeast, water that is too cool is a problem too, because the yeast wakes up poorly.
4. Too much salt or sugar. A little sugar speeds yeast up, but a lot of it slows yeast down, and salt slows it as well. Sweet, rich doughs are always slower, so give them more time and a warmer spot.
5. It has not had long enough. At about 27°C (80°F) a dough rises in around two hours. Colder than that, it needs longer. Go by the dough, not the clock.
6. The sourdough starter was not ready. If the starter does not wake up, the dough will not rise. Use it when it is at its bubbliest.

What Temperature Should Dough Rise At?

Yeast makes gas fastest at about 35°C (95°F), close to body temperature. Faster is not always better, though. At that heat it also makes more sour, unpleasant-smelling by-products. A rise nearer 27°C (80°F) still finishes in a couple of hours and tastes better.

Temperature	What the dough does
Below about 20°C	Very slow. A typical winter kitchen is 18 to 21°C, and an hour or more gets added to a rise that takes about two hours at 27°C.
About 27°C (80°F)	A steady rise in around two hours, and the best flavour.
About 35°C (95°F)	The fastest gas production, but with more sour, unpleasant-smelling by-products.
Sourdough: 20 to 25°C	Where the wild yeast grows best. Warmer than that and the bacteria speed up, so the dough turns sour.

When the kitchen is cold and I need the dough moving, I go warm, which is what the sink method below does. When I want the bread to taste of something and I have the time, slower and cooler is the better trade.

Water Temperature for Yeast

It depends on which yeast you have.

• Instant yeast does not need waking up. Mix it straight into the flour.
• Active dry yeast wants warm water first, about 41 to 43°C (105 to 110°F). Cooler than that and the yeast recovers poorly and gives off substances that weaken the dough.
• Fresh yeast is alive and perishable. Keep it in the fridge, use it within a week or two, and crumble it into lukewarm water.

No thermometer? If you can comfortably keep your hand in the water for 20 seconds, it is safe.

You can use half of the recipe’s water to wake the yeast, then add the rest warm when you mix. That helps against the cold flour and the cold bowl. Once mixed, the dough should feel slightly warm. If it does not, do not panic. The proofing spot will sort it out.

Is My Yeast Dead? The 15 Minute Test

In winter I always check the yeast before it touches the flour.

• Use lukewarm water, around body temperature, slightly warmer is fine
• Add a small pinch of sugar
• Use a bowl or jug big enough for it to grow
• After 15 minutes you should see bubbles
• After 20 minutes the activity should be obvious and growing

If nothing moves after 20 minutes, something is wrong. The yeast is old, dead or was stored badly, or the water was too hot. Stop and start again straight away with yeast from a different packet, and check the water temperature again.

Should You Add More Yeast in Winter?

Only if you are baking the same day. Cold slows fermentation down, and the cleaner fix is time and a warm proofing spot rather than a bigger dose. If you are against the clock a small increase will get you there, but it costs you flavour, and the dough swings from underproofed to overproofed faster than you expect. For anything with a long or overnight rise, leave the yeast alone: too much yeast for the length of the ferment is one of the most common reasons a dough collapses or tastes boozy. My pizza dough calculator works the dose out from your timing and kitchen temperature if you would rather not guess.

Where to Let Dough Rise in a Cold House

The sink method (my go-to)

This is the most reliable method I have used in cold home kitchens and draughty commercial kitchens.

• Put the dough in its bowl
• Cover the bowl with cling film or a cloth
• Stand the bowl in the kitchen sink
• Add warm water until it comes about a third of the way up the bowl

I start with water at around 40°C (104°F). As the sink takes the heat, the water drops and settles around 36°C (97°F), which gives a quick, reliable rise. You do not need to refresh the water for a one hour proof. For a longer one, add a little more warm water. If you can comfortably put your hand in the water, it is right.

It blocks draughts and keeps the warmth steady around the bowl, and it works every time in winter.

Oven proofing

If your oven has a low or proofing setting around 30 to 35°C (86 to 95°F), it works very well for the first and second proof. It is especially useful for enriched doughs, shaped dough on its second proof, and sourdough in a cold kitchen. Do not go hotter. Slow, steady warmth beats speed.

The fridge, when you want flavour

Cold is not always the enemy. In the fridge, dough rises about ten times slower than in a warm room, and that long, slow rise gives the yeast time to build flavour. Cold dough is also stiffer and easier to shape. That is the whole point of my overnight Chelsea buns.

Oil the surface

Whether or not your dough has oil in it, a light film of oil on the surface while it proofs keeps the warmth in, stops it drying and helps it stretch on the second proof. It is most useful once the dough is portioned on the counter.

Sourdough Not Rising?

A starter is a partnership between wild yeast and lactic bacteria, and the two do not want the same temperature. The bacteria like it warm, around 30 to 35°C, while the wild yeast grows best at about 20 to 25°C. So a hot proof will not buy you a faster rise. It buys you a sour, slack dough that never quite lifts.

• Always wake your starter first, exactly as your recipe says
• Keep it around 20 to 25°C, not the warmer temperatures you would use for commercial yeast
• Use it when it is at its bubbliest
• If the starter does not wake up, the dough will not rise

Cold starters do need waking up before you mix. Gentle warmth and time, though, not heat.

If the loaf did rise but still came out heavy, see why sourdough is dense.

When to Restart

There are two clear points.

The yeast does not activate. No bubbles after 20 minutes. Stop, change the yeast and check the water temperature again.

The dough does not move. No expansion or bubbles after 30 minutes in a warm proofing spot. Stop and restart.

Waiting longer will not fix dead yeast. Restarting early saves time and frustration.

These methods matter most for:

• Sourdough bread
• Sourdough focaccia
• Greek flatbread
• Laffa bread
• Overnight Chelsea buns, where the whole point is a long cold prove

FAQ

Can I still use dough that did not rise?

If the yeast is dead, no amount of waiting will fix it, so restart with fresh yeast. If the dough is just slow, move it somewhere warmer and give it time.

How long should dough rise?

At about 27°C (80°F), around two hours. In a cold kitchen it can take an hour or more longer, and in the fridge about ten times as long. Go by the dough, not the clock.

What temperature kills yeast?

Keep the water no hotter than about 43°C (110°F), the top of the range dry yeast is woken up in. Above that you are guessing, so I would not risk it. The heat of the oven kills the yeast in the first minutes of baking, which is why the rise stops there.

Does salt kill yeast?

It slows yeast down rather than killing it outright, which is one reason salty and very sweet doughs are slower to rise.

Do I need to activate instant yeast?

No. Instant yeast goes straight into the flour. Only active dry yeast needs warm water first.

Can I proof dough in the oven?

Yes, if it has a low or proofing setting around 30 to 35°C. Do not go hotter.

Why is my dough rising so slowly in winter?

Because the kitchen is cold. At 18 to 21°C yeast works slowly. Use the sink method, the oven or a warmer room, and the dough will move again.

A Few Words from the Chef

In winter kitchens, dough usually is not failing. It is simply cold. Wake the yeast properly, start warm and control where the dough proofs, and it becomes predictable again whatever the season. A cold kitchen is a scheduling problem, not a baking one.
