Know Your Sourdough Starter Feedings.

[BGKYSmoker]

One of the most powerful tools in sourdough baking isn’t a special flour or expensive equipment.
It’s understanding feeding ratios.
If you’ve ever seen 1:1:1 or 1:2:2 and felt confused, you’re not alone. Let’s break it down in a simple, practical way so you can confidently choose what works for your kitchen.
First, what do these numbers mean?
They represent the ratio of:
Starter : Flour : Water
So when you feed 1:1:1, you are giving equal parts starter, flour, and water (by weight).
When you feed 1:2:2, you are giving one part starter and double the amount of flour and water.
That small shift makes a big difference in fermentation speed.
Let’s talk about 1:1:1.
This ratio gives your starter a smaller “meal.” Because there’s less fresh flour available relative to the amount of active yeast and bacteria, it eats through the food quickly. That means:
• It peaks faster
• It becomes active sooner
• It also collapses sooner
• It requires more frequent feeding
In a warm kitchen, a 1:1:1 feeding can peak in just a few hours. This ratio is great when you want quick activity — for example, when preparing to bake the same day.

Now let’s look at 1:2:2.
Here, you’re giving the same amount of starter a larger supply of food. The microorganisms have more flour to ferment, so the process stretches out longer. That means:
• It peaks more slowly
• It stays at peak longer
• It doesn’t need feeding as often
This ratio is especially helpful in warmer climates or busy schedules. If your starter tends to peak and collapse before you’re ready to bake, increasing the feeding ratio can stabilize it.
So which one should you use?
It depends on three main factors:
Room temperature – Warmer environments speed up fermentation.
Your schedule – Do you need it ready quickly, or do you need it to last longer?
Starter strength – A mature, strong starter handles larger feedings well.
There is no “better” ratio — only the one that fits your timing and environment.
Think of feeding ratios as a control dial. If your starter is racing ahead of you, increase the ratio. If it feels sluggish and you need faster activity, reduce it.
When you understand this, sourdough stops feeling unpredictable. You’re no longer reacting — you’re adjusting intentionally.
The goal is not just feeding your starter.
The goal is learning how to manage fermentation with confidence.
Once you master ratios, everything becomes more consistent — and your baking becomes far more reliable.

I'll have to keep this in mind for summer. I dont like to bake much in summer, its counterintuitive running the AC, then fighting that with an over 400 degree oven. My starter died last summer because I was remiss in keeping it alive properly. I had a neighbor that could quickly give me some but the 1-2-2 method look like it might buy me some more time between feedings.

How often do you feed your starter? Of course that may be a silly question for someone who bakes sourdough constantly all year round.

Nice summary there.

I use 1.1.1 95% of the time. Once it's woken up from being in the fridge for a few weeks, my baby will triple in size within 3 hr (at 80oF).

My room is usually the coldest in the house--the kitchen if you can believe it. Best item I ever got was one of those little controllable hot plates. Set the temp and the time and ....fuggedaboudit.

I've tried the top of the fridge and yes, it was warmer there but no where near as good as this hot--errrr warmplate. IMO, it's not a gimmick as it really does what it's supposed to do.

Great explanation.
Reminds me I need to build up my discard jar. I've only made 1 true sourdough in the past year.

When I first saw the thread title I thought it read

Things I needed to know... Thanks brodder ...

The goal is learning how to manage fermentation with confidence.

Same as using a stick burner -- Fire management with cinfidence...

I need to build up my discard jar.

So every time you feed you take some out first, called discard... Keep adding discard to a seperate jar and save ?? on the counter/in the fridge ?? Does this discard not die and is no good ??

Great post! I don't even make sourdough and it helps me understand... in case I decide to try.

Keep adding discard to a seperate jar and save ??

Discard goes in the trash , then feed the volume left behind in the starter jar .

I keep mine in a pint Mason jar .
I keep an empty pint Mason jar on the counter .
When I feed , I weight the empty jar , then tare the scale .
So when I weigh the discarded starter jar it tells me the amount left in the jar .
Like this ,


Tells me if feeding 1:1:1 that I need 40 grams .

Yes I save all my discard in a separate jar and keep it in the fridge. I make enough bread, rolls, and pancakes to keep it pretty fresh.
I thought we went through this at the last gathering, but you were in a food coma from the pancakes and bacon. I used up 2 cups of discard making pancakes on Friday and Saturday.


Here's my 2 wide mouth pint jars for discard and starter. My starter jar (rubber band ring) was empty. I made a 1:1:1 fresh starter tonight by taking 50 grams from the refrigerated discard jar and adding 50 grams flour and 50 grams cold filtered water. It sits on the counter and will be done by the morning.
I will fold all the starter back in the discard jar in the morning.
I'm making a double batch of tangzhong cinnamon rolls tomorrow and that will use up a cup of discard.
I repeat Tuesday night as I'm making 4 loaves of bread on Wednesday.
