What You’ll Learn
- Why winter slows fermentation.
- How to use warmer water safely.
- Where to keep starter and dough.
- How to extend bulk without overreacting.
- How to create a stable routine.
Quick Answer
In winter, use warmer water, keep your starter and dough in a stable warm place, allow more time and avoid assuming slow fermentation means failure. Dough temperature matters more than the season itself.
This lesson is part of our Seasonal Baking section: “Adapt your baking throughout the year.”
Why Winter Slows Sourdough
Lower temperatures reduce microbial and enzymatic activity.
Use Warmer Water
Moderately warm water can help achieve a sensible final dough temperature without exposing the starter to damaging heat.
Find Stable Warmth
A cupboard, insulated box or temperature-controlled proofer can be more useful than moving the dough between hot and cold spots.
Give It More Time
A winter bulk may take hours longer than the same dough in summer.
Starter Feeding
A room-temperature starter may need less frequent feeding in a cold kitchen because it peaks more slowly.
Avoid Sudden Heat
Direct radiators, very hot ovens or boiling water can create uneven conditions.
From Our Workshop
Winter is when bakers often think their starter has become weak. Usually it has just become cold.
Bake Slower Tip
Warm the water before you warm the whole kitchen.
Common Mistake
Do not put starter somewhere hot enough that you would not comfortably leave your hand there.
Today You Learned
- Winter fermentation is slower.
- Warmer water helps.
- Stable warmth beats hot spots.
- Allow more time.
- Slow does not mean dead.
Frequently Asked Questions
Can I use the oven light?
Possibly, but check the actual temperature first.
Why does my starter take twice as long?
A colder starter often peaks much later.
Should I feed more often in winter?
Not necessarily.
Can I use a proofing box?
Yes.
Should I increase starter percentage?
You can, but temperature control is often simpler.
Bake With the Season
Winter sourdough is easier once you create one stable warm place.

Make it practical
Use this guide as a starting point, then compare the advice with what you observe in your own starter, dough and oven. Small notes from each bake make future decisions much easier.
