If your sourdough starter looks like it’s doing absolutely nothing, it’s easy to assume something has gone wrong.
But in most cases, a quiet starter is not a failed starter—it’s a starter that hasn’t had the right conditions, or enough time, to show you what it can do yet.
Let’s go through what’s actually happening and what to do next.
The short answer
If nothing is happening yet, don’t change everything.
Keep your feeding routine consistent, keep your starter warm, and give it more time.
Most “inactive” starters simply need stability—not more intervention.
First: what “nothing happening” usually means
When people say nothing is happening, they usually mean:
-
no visible bubbles
-
no rise after feeding
-
no obvious change in texture or smell
But fermentation is still happening at a microscopic level long before you see visible activity.
Your starter may already be developing—it just hasn’t built enough strength yet to show clear signs.
The most common reasons your starter looks inactive
1. It’s too cold
Temperature is the biggest factor in starter activity.
If your kitchen is cool, fermentation slows right down.
At lower temperatures, your starter is still alive—it just works much more slowly.
2. It hasn’t had enough time
This is especially common with dehydrated starters.
Early on, it’s normal to see:
-
a quiet first day or two
-
a sudden burst of activity
-
then another quiet phase
This is part of the natural stabilising process.
3. Too many changes too quickly
One of the biggest delays in activation is constant adjustment.
Changing things every feed—flour, ratios, timing—can confuse the process and make it harder for the culture to settle.
Starters need consistency more than experimentation.
4. Feeding may be out of balance
If your starter is very runny, very thick, or not feeding regularly, it may simply need a more stable routine.
A simple, consistent feeding pattern is more effective than frequent changes.
5. It’s in a “quiet phase”
Many starters go through a stage where they appear active early on, then suddenly go quiet again.
This can feel like a setback, but it’s actually part of development.
The culture is adjusting internally before becoming more stable and predictable.
What you should do right now
If nothing is happening yet, the best approach is simple:
-
keep feeding on a consistent schedule
-
keep it warm (as stable as possible)
-
avoid changing flour or ratios every feed
-
give it a few more days before reassessing
The most common mistake at this stage is doing too much, too soon.
What NOT to do
Try to avoid:
-
restarting too early
-
adding sugar, yeast or “boosters”
-
constantly changing feeding ratios
-
assuming it has failed within the first few days
These usually slow progress rather than help it.
When should you actually worry?
There are only a few real warning signs:
-
visible mould (fuzzy or coloured growth)
-
a strong rotten or putrid smell that doesn’t improve
-
no change at all after consistent care over an extended period of time
If none of these are present, your starter is almost always still developing.
Nikki’s note
This is the stage where most people give up too early.
From experience, many of the strongest starters I see have gone through a completely quiet phase before suddenly becoming active and reliable.
The key difference is not what people did—it’s that they stayed consistent long enough for the culture to stabilise.
