So, you got your very first sourdough starter and now you’re feeling completely overwhelmed.

Or maybe you don’t have your starter yet. Maybe you want to make your own starter and you’re too afraid to start.

I’ve been in your shoes before. Jumping into the world of sourdough feels really overwhelming to begin with. When I got my first sourdough starter unexpectedly – it my husband walked in from work one day holding a loaf of bread and a sourdough start – I knew exactly ZERO things about sourdough baking.

Google became my very best friend. I read so many blog posts trying to figure out what in the world I was supposed to do with this new addition to my family. Suddenly I had a fifth child, or so it seemed.

Another “mouth” to feed every single day.

***Insert mild panic attack while trying to pretend like I totally knew what I was doing***

This blog post is going to have A LOT of information. It’s all the things I wish I would have known about my sourdough starter when I first got started.

First, let’s take a look at the sourdough life cycle:

So here you have it … it looks something like this: FEED –> RISE –> PEAK –> (This is when you want to bake) –> FALL –> DISCARD & FEED and the cycle begins again. For a deeper dive into the sourdough life cycle, you can read this blog post. It goes into depth on each phase of the life cycle.

Sourdough Starter Terminology

Starter

A natural, living yeast that is used to leaven bread. It is a living organism, so it needs to be fed and cared for in order to thrive and act as a leaven. Also referred to as your Mother Starter.

Your starter is a mixture of fermented flour and water, which cultivates the wild yeast in our environment to a form that can be used to leaven bread. It’s a natural yeast, a living organism, that makes bread rise.

A good, strong starter is the foundation of a great loaf of bread. Healthy starters are maintained with regular feedings. Along with raising the bread, starter also helps to give sourdough bread that amazing, tangy and complex flavor.

Gluten begins to break down during fermentation. Because sourdough bread has a long fermentation process, it’s easier to digest and many people with gluten sensitivities can eat this type of bread without all the side effects of store-bought bread.

Feed

Your starter is a mixture of fermented flour and water, which cultivates the wild yeast in our environment to a form that can be used to leaven bread. It’s a natural yeast, a living organism, that makes bread rise. And because your starter is a living organism, it needs to be cared for.

Feeding is the process of adding fresh flour and water to your starter to activate it for baking. Feeding your starter consistently is the key to creating and maintaining a healthy leavening agent for your bread. It only takes a few minutes each day.

When you feed your starter, you will transfer a small portion of your start into a clean jar and add in at least equal parts of flour and water. Mix it up until everything is combined and there are no dry bits of flour remaining. Then just sit back and then watch it start to activate.

Refresh

Another word for feeding your starter.

Levain

An off shoot of your main (or mother) starter that you use for baking. It’s kind of like a mini starter that you make fresh for a certain bake. Also called a leaven.

You’ll take a small amount of start and feed it in a new container for a specific recipe. Then you’ll use the entire levain in your baking. You won’t save any levain to feed like you would if you were baking with your mother starter.

Using a levain is nice because you can change the flavor profile of your starter without changing your mother starter. You can make a wheat levain by feeding it all whole wheat flour, you can make a sweet levain by adding sugar or you can make a stiff levain by adding more flour than water. Some recipes will call for a specific type of start, so this is how you can use different types of starts without having to maintain multiple types of starts every day.

Active (Ripe) Starter

This is what we call starter when it’s at its peak strength before it begins to fall. This is the prime time to use it to leaven your bread.

You’ll know your starter is active and at it’s peak when it has a sweet, yeasty smell, is full of air bubbles, has doubled (or even tripled) in size and the top is no longer domed. If the top of your starter is domed, that means it’s still growing and isn’t ready to bake with yet.

Inactive Starter

Inactive starter is sourdough starter that is not currently bubbly. Your starter is active when it’s bubbly and rising. Once it hits its peak, starter will begin to fall. It’s the law of gravity – what goes up, must come down. So once starter has fallen it is no longer able to leaven your bread well. It’s now considered inactive starter.

But don’t worry … inactive starter just needs food, time and warmth to become active again.

And before you ask this question, here’s the difference between discard and inactive starter:

Discard = the portion of your starter that was removed as excess.

Inactive starter = tired starter (it’s used up all its energy) that needs to be revived.  

Discard

While it may seem wasteful, discard is an important part of sourdough maintenance. Discard refers to the portion of your sourdough start that you do not carry over. Typically, you’ll take only half (or less) of your start to feed in a new, clean jar. The rest becomes discard. Discarding helps your starter from getting too large and it also helps to keep the right acidity level for your starter to thrive.

Discard can be either thrown into the trash (don’t wash it down your drain) or used in many different recipes. You can use discard to make cookies, muffins, pancakes, crackers and so many more yummy things. You can also feed your discard to your chickens, use it to thicken your soup or dilute it and use it to help fertilize the plants in your garden.

Hooch

A black/grey liquid that forms on the top of your starter. It’s an indication that your starter is hungry and needs to be fed. Your starter did not die, it’s not bad … it’s just hungry. Hooch tells you that your starter has used up all it’s food source (flour) and needs more.

While it looks a little scary and smells terrible, hooch is actually a protection for your sourdough starter. That layer of liquid is a byproduct of fermentation and it actually creates a barrier from the air that helps to slow down growth of unwanted bacteria or mold. It also keeps the environment slightly acidic, which supports the wild yeast and good bacteria.

If you want a really strong, sour flavor you can stir in your hooch and then feed your start. Or, you can pour off the hooch and then scoop a small spoonful from the bottom of your jar and then feed that in a clean jar. If your start hasn’t been fed in a long time, you may need to feed it a few times before it’s really active and ready to bake with again.

So, what’s the difference between active starter, inactive starter and discard? The difference is in the feeding. Active starter has been fed consistently so it’s active, bubbly and ready to bake with. Inactive starter was fed recently, but has hit its peak and fallen – it’s used up all its energy and needs to be fed again to be optimal for baking. Can you bake with inactive starter? Yes, you definitely can. But it’s BEST to bake with active starter. Discard is the excess – the starter you don’t need to carry over for your next feeding. But, if you ever need to revive your discard, a few consist feedings will have it back to active again. Discard is just really hangry sourdough starter.

How do I know when my starter is ready to use?

Your starter is active and ready to use (at its peak) when it’s doubled, maybe even tripled, in volume. It should be full of bubbles and have a sweet, yeasty smell to it. The top of your starter should be flat and have so many bubbles it almost looks foamy. If the top of your starter is domed upward, it’s not ready yet. A domed top tells you that it’s still releasing energy and growing. Wait until it flattens out.

You could also use the “float test.” All you need to do is fill a small bowl with room temperature water. Then drop a small spoonful of sourdough starter into the water. If the starter floats, it’s a sign that it is active and can leaven your bread. But, take this test with a grain of salt. Many people say the float test isn’t accurate because all it really shows is that your starter has enough gas in it to float, it doesn’t necessarily show you how strong it is and if it can leaven bread.

Troubleshooting Common Problems

Even the best starters can have off days. Don’t panic — most issues are easy to fix once you know what’s going on.

My starter isn’t rising well.
This usually means it needs a little more warmth or food. Try moving it somewhere cozy (around 75°F) and feeding with fresh flour and water. Whole-grain flour, like rye or whole wheat, can give it a boost of wild yeast and bacteria.

It smells weird — not sour, but funky.
A healthy starter smells tangy, slightly fruity, or like fresh bread dough. If it smells like rotten cheese, nail polish, or something foul, it’s probably over-fermented or contaminated. Give it a few feedings at regular intervals to refresh it. If it turns pink, orange, or grows fuzzy mold, it’s time to toss it and start over.

There’s liquid on top.
That’s called hooch — it’s just a sign your starter is hungry. Pour it off or stir it back in, then feed your starter to bring it back to life.

It’s super runny or too stiff.
Small variations in flour absorbency or measuring can cause this. Adjust by adding a bit more flour or water until it’s thick like pancake batter consistency. I like to keep my sourdough starter slightly on the stiffer side. So, I might feed 100 grams of water and 105 grams of flour.

It rises and falls too quickly.
That’s probably because you’re feeding your sourdough starter at a 1:1:1 ratio, so it’s hitting peak in probably 3-5 hours. If you don’t want to feed it this often, you can feed it at a higher ratio. Try feeding it at a 1:3:3 or 1:5:5 ratio and see how it does. If I feed my starter at a 1:5:5 ratio (meaning 1 part starter and 5 parts water and flour – 10 grams start: 50 grams flour: 50 grams water), it will usually hit peak and fall within about 12 hours. So a 1:5:5 ratio means I can feed my starter morning and night and not think about it in between.

Keeping your sourdough starter strong & active long term

Once your starter is established, it doesn’t need much to keep it strong — just consistency and good habits.

• Feed it regularly. If you bake daily, keep it at room temp and feed it every day. If not, store it in the fridge and feed weekly.
• Stick to a balanced ratio. Equal parts starter, flour, and water by weight (1:1:1) works fine, but over time you may notice this feeding ratio actually creates a weaker starter. Try feeding at a higher ratio and see how much stronger your starter is. If our sourdough starter was a toddler, feeding at a 1:1:1 ratio would be like giving them a handful of crackers and a fruit snack. Feeding at a 1:5:5 ratio is like feeding them a well-balanced meal. A balanced meal will keep a toddler full longer than some crackers will – same with your sourdough starter. A bigger meal keeps it full longer.
• Boost with whole grains occasionally. Every few weeks, use a spoonful of whole wheat or rye to give your starter extra nutrients. This helps prevent a sluggish starter. This is especially helpful if you’ve stored your starter in the fridge.
• Keep things clean. Transfer to a fresh jar every so often to prevent buildup and crusty residue. Ideally, you’ll use a clean jar with every feed, but life is busy and that doesn’t always happen. Make sure to change your jar every couple of days.
• Avoid contamination. Use clean utensils and avoid getting grease or soap in your jar.

How often should I feed my sourdough starter?

If you are keeping your starter out on the counter you need to feed it every 12-ish hours. I like to feed my starter around 8 am and 8 pm because that works with my schedule well. You can find what works best for your schedule.

Learning how to feed at different ratios makes it easier to time when your starter will be ready to bake with. We’ll discuss feeding ratios in depth in a future blog post. But just know, the more you feed your starter, the less frequently you need to feed it.

If you don’t want to have to feed your starter twice a day for the rest of your life, you can store it in your fridge. A starter in the fridge can go a week in between feedings without any problems.

How flours impact your sourdough starter

Different flours feed your starter in slightly different ways. There’s no “right” or “wrong” flour to use to maintain your starter, just remember that starters love consistency. So, try to pick a flour and use that almost exclusively for your starter. Yes, you can swap your flour, just try to do it gradually so you don’t shock it. And remember, different flours will look different, so if you change your flour, expect to notice a difference in your starter.

• Whole Wheat:
  Full of natural enzymes and nutrients, whole wheat flour gives your starter a serious boost — perfect for getting a sluggish one going again. It tends to ferment faster and produce a tangier flavor.
• Rye:
  Rye flour is like an energy drink for your starter. It ferments quickly, encourages strong yeast activity, and gives your starter a rich aroma. Even if you don’t bake rye bread, using it occasionally in feedings keeps your starter lively.
• All-Purpose or Bread Flour:
  These are reliable everyday flours. They make for a milder, less acidic starter and are great for maintaining once your culture is mature. Bread flour adds extra strength and elasticity to your dough.
• Specialty Flours (spelt, einkorn, etc.):
  These can add depth of flavor but may behave differently due to lower gluten or different absorbency. It’s best to use them in combination with all purpose for feedings.

Common Signs of Problems with Your Starter

Sign	What it Means	What to Do
Gray/black liquid on top	That’s hooch. Your starter is hungry.	Pour off the hooch and feed your starter
Bubbly, doubled, smells sweetly sour	It’s perfectly healthy	Time to get baking!
No bubbles after 24 hours	Your starter is too cold or underfed	Place it somewhere warm and feed it again. I like to keep my starter in the microwave when it’s cold
Strong alcohol or acetone smell	Your starter is over fermented and missed it’s peak	Feed again before using. Try feeding at a higher ratio so you don’t have to feed it around the clock
Pink or orange streaks	Your starter is contaminated	Throw it away and start fresh
Fuzzy mold	Your starter is contaminated	Throw it away and start fresh
Watery or thin texture	Too much water or your starter is weak.	Feed with a little extra flour and keep it at room temperature for a few days
Thick, stiff paste that doesn’t expand	Not enough water or starter is very young.	Add a touch more water and keep feeding daily until active
Gray or dark crust around the edges	Dried starter (normal if it’s been sitting out and isn’t covered well).	Scrape off the dry layer and feed what’s still moist underneath
Starter rises fast then collapses	Very active yeast, short peak time	Feed at a higher ratio and/or store in a slightly cooler spot

Quick Tip: Most starters can bounce back from odd smells or sluggish days with consistent, room-temperature feedings. True mold or bright discoloration, however, means it’s time to start over.

Frequently Asked Questions:

1. Do I have to discard every time I feed it?

As a verb, discarding is really important in maintaining a strong and healthy starter.

It is not waste. It has a purpose. I like to think of it like trimming your hair, pruning a tree, or thinning out plants in your garden. Sometimes you have to remove some so that it can keep growing and maintain strength.

So why do we discard? First of all, it helps keep your starter from growing too large.

First of all, it helps to keep your starter from growing too large. The other reason we discard is to help keep your starter strong and healthy. If you never removed any of your start, it gets hard to take care of and feed well. And if you aren’t feeding it well, it can become overly acidic.

2. Did I kill my starter?

Almost every time I get this question the answer is NO!

Unless you open your sourdough starter jar and see the top has mold growing on it, you did not kill your starter. The layer of grey/black liquid you see on top of your starter is hooch. And it’s totally ok and even normal. It’s just a sign that your starter is very hungry and needs to be fed. Just pour the hooch off and feed your starter and it will be back to bubbling really soon.

3. Why isn’t my starter rising and bubbly like your starter?

It could be too cold, underfed, or using low-quality flour. Try moving it to a warmer spot, feeding it more consistently, and using unbleached, whole grain flour (rye is my favorite) to boost activity. Whole grain flours are like superfoods for your sourdough starter.

4. What are the jars you always use for your starter?

First of all, you can use any jar to hold your starter. You don’t need to buy a special, fancy sourdough jar. That being said … I LOVE these Weck jars. They are the perfect size. I love the wide mouth and the glass lid. I’ve tried several different jars and these are the ones I keep coming back to.

And for a list of all my favorite sourdough products, you can check out my Amazon storefront here.

5. What types of flour can I use for my starter, and why?

You can use just about any unbleached flour made from grains — wheat, rye, or spelt are great choices. Whole-grain and rye flours are especially helpful for new starters because they contain more wild yeast and nutrients that encourage fermentation. Once your starter is strong, you can maintain it with all-purpose or bread flour for a milder flavor and smoother texture.

6. How should I store my starter when I’m not baking?

If you bake often, keep your starter at room temperature and feed it daily. If you only bake once a week (or less), store it in the refrigerator. Feed it once before putting it in the fridge, then bring it back to room temperature and give it a fresh feeding before baking again.

7. What’s discard good for?

Discard is the portion of starter you remove before feeding. It’s not “waste” — it’s just unfed starter that’s past its peak. You can use it to add tangy flavor to pancakes, muffins, waffles, crackers, cookies, or even savory bakes like pizza dough and biscuits.
If you’re new to sourdough baking, keeping a small jar of discard in the fridge makes it easy to try new recipes without throwing any away. I’ve got several fun discard recipes you can find right here.

Starting and maintaining a sourdough starter might seem intimidating at first, but with a little patience and consistent care, it quickly becomes a reliable, lively companion in your kitchen. Remember, every starter is a little different — it’s perfectly normal for it to bubble, smell, or behave in ways that are unique to your environment. By feeding it regularly, keeping it clean, and understanding the signs of a healthy versus struggling starter, you’ll set yourself up for successful, flavorful bakes every time. So don’t worry about perfection — enjoy the process, experiment with flours and recipes, and have fun watching your starter come to life. Happy baking!
