Caring for Your Starter
A sourdough starter needs attention, but not constant attention. Some starters live on the kitchen counter and are fed every day, while others spend most of their time quietly in the fridge, coming out only when there is bread on the horizon. Neither approach is inherently better; what matters is finding a rhythm that works for both you and your starter.
There is no perfect routine that works for everyone. How often you bake, how warm your kitchen is, when you want to make your dough and how much time you have will all influence the way your starter behaves. Once you begin to understand those things, caring for it becomes much simpler. You do not need to feed it by the clock. You simply need to recognise when it is active, when it needs fresh food, when it is better left alone and when it is time to wake it up again.
Giving Your Starter a Home
Where your starter lives has a surprisingly big influence on how quickly it moves through its cycle. A starter kept at room temperature remains active and therefore needs regular feeding, so a calm spot in the kitchen, away from direct sunlight and not too close to a radiator or oven, is usually a good place to keep it. A glass jar makes it easy to see what is happening inside, while keeping the rim and sides clean helps prevent dried starter from accumulating.
An elastic band around the jar is a small but useful habit, too. Place it at the level of the starter just after feeding and you have a simple reference point for seeing how far it rises afterwards. Over time, this tells you far more about its rhythm than a fixed number of hours ever could.
Your starter does not, however, have to live on the kitchen counter permanently. If you do not bake very often, the fridge can be a much more practical home, allowing the culture to slow down while you get on with everything else.
The Everyday Rhythm
An established starter that you use regularly can happily be kept at room temperature, in which case feeding simply becomes part of your everyday rhythm. Exactly how often that happens depends on how quickly your starter is using its available food. A warm kitchen can make fermentation move considerably faster, while a cooler environment may slow the same starter down, and your feeding ratio influences the length of the cycle as well.
Daily feeding is therefore not a goal in itself. You feed your starter because it has used much of its available food and needs fresh nourishment. That small distinction changes the way you look at the process: the clock is not what decides when to feed. It is the combination of activity, temperature, feeding ratio and your own plans.
For the different feeding ratios and the practical differences between 1:1:1, 1:2:2 and 1:4:4, see Feeding Your Starter.
What If You Forget to Feed It?
It happens, and an established starter is usually much more forgiving than you might expect. Missing one feeding does not normally mean that you have lost it. After a while, it may look distinctly hungry: perhaps it has completely fallen back, smells more sharply sour or slightly alcoholic, or has developed a layer of liquid on top. These are all signs that it has used much of its available food.
In most cases, the answer is simply to feed it again and see how it responds. Sometimes it will become lively again after a single feeding; after a longer period without food, it may need several feedings before its familiar rhythm returns. The important thing is not to panic and change five things at once. Keep the conditions reasonably consistent, give it fresh food and observe what happens.
A missed feeding is not the same as a spoiled starter. For signs that mean you should discard it, such as visible mould or striking pink or orange discolouration, see Starter Health & Safety.
When Life Gets in the Way
Not everyone bakes every day. Perhaps you bake three loaves in one week and then nothing for a month, or maybe you are going on holiday, life becomes busy, or you simply do not feel like baking for a while. Your starter does not have to fight your schedule.
Once it is established and stable, it can be kept in the fridge, where the colder temperature slows fermentation considerably and means you need to feed it much less often. The fridge is therefore not an emergency solution or a sign that you are neglecting your starter. It is simply another rhythm, one that happens to suit a less frequent baker.
Keeping Your Starter in the Fridge
If you do not bake often, you can feed your established starter and then place it in the fridge, where it will continue to ferment at a much slower pace. A practical routine is to keep a small amount of mother starter, feed it and then return it to the fridge. Depending on how active your starter is and how cold your fridge runs, roughly weekly feeding can be used as a starting point, although some starters will comfortably go longer. It is better to pay attention to the starter itself than to follow a fixed calendar.
When you take the jar out of the fridge, it may look quite different from a freshly fed starter. It may have fallen completely, developed a layer of liquid or smell noticeably more sour, but none of these things automatically means that something is wrong. The cold simply changes the pace at which the culture works.
The fridge slows your starter’s life. It does not stop it completely.
A Simple Rhythm for Different Bakers
There is no reason to follow the same starter routine as someone who bakes every day. The most useful routine is usually the one that fits naturally around how often you actually bake.
You bake several times a week
If you bake several times a week, keeping your starter at room temperature may be the simplest option. Feed it regularly and pay attention to how long it takes to reach its peak. With time, you can begin to plan your baking around that rhythm rather than trying to make the starter conform to a particular timetable.
You bake about once a week
If you bake roughly once a week, the fridge is likely to be more convenient. Keep a small mother starter and take it out when you want to bake, then give it one or more room-temperature feedings until it is clearly active and reliable again.
You bake only occasionally
If baking is something you return to every now and then, let your starter spend most of its time in the fridge. Keeping the amount small means you use very little flour while maintaining it, and when you want to bake again, you can simply take it out and give it the time and food it needs to become active once more.

From Mother Starter to Baking Starter
You also do not need to maintain a large jar of starter simply because you want to bake regularly. A small mother starter is enough; when you are ready to bake, you can use a portion of it to build a larger baking starter that matches the amount required for your recipe.
This keeps your everyday starter small, while extra flour and water are only used when you are actually going to bake. It also creates a useful distinction between the starter that quietly lives in your kitchen and the starter you build specifically for a particular loaf.
For the practical feeding ratios and methods, see Feeding Your Starter.
Waking Up from the Fridge
When you want to bake again, take your starter out of the fridge and give it some time to come back towards room temperature. Before feeding it, take a moment to look and smell: what does it look like, is there liquid on top, and how much activity can you see?
Once you have fed it, watch how it responds rather than assuming that it will be ready after a fixed number of hours. A healthy, established starter may become noticeably active again after a single feeding, while one that has spent a longer period in the fridge may need several feedings before its rhythm becomes strong and predictable again.
Wait until you see the signs you have learned to recognise: clear activity, growth, bubbles and a recognisable peak. Those signs tell you considerably more than the amount of time written on a clock.

Small Habits Make a Difference
Caring for a starter ultimately comes down to a handful of small habits that make it easier to understand and keep healthy. Keep the jar clean and wipe dried starter from the rim before it builds up, mix each feeding thoroughly and mark the level when you want to keep track of how much your starter rises. If you are trying to understand why it is behaving differently, change one variable at a time rather than changing the flour, ratio and temperature all at once.
Most importantly, learn what your own starter looks like when it is healthy and active. It may rise faster one day than the next, produce more bubbles, smell slightly sharper or develop a somewhat different texture. Those changes do not necessarily mean that something needs fixing. A living culture is not perfectly consistent, and part of caring for it is learning the difference between normal variation and a genuine problem.
A living culture changes.
Sometimes the Best Care Is to Leave It Alone
With sourdough, it is easy to feel as though you should always be doing something: feeding, stirring, looking, checking again, moving the jar or wondering whether the temperature is quite right. But a healthy starter does not need all that attention.
When it is active on the counter, feed it when it needs fresh food. When it is resting in the fridge, let it rest. You do not need to wake it every day simply to reassure yourself that it is still alive.
Good care does not mean constant intervention. It means knowing when your attention is needed — and when your starter can simply get on with its own work.
Your Rhythm and Your Starter’s Rhythm
In the end, caring for a starter is less about following a perfect schedule and more about finding a rhythm that fits naturally into your life. Perhaps your jar sits beside the coffee machine every morning, and feeding it becomes as ordinary as making your first cup of coffee. Perhaps your starter lives mostly in the fridge and only comes out when you feel like baking. Both approaches can work.
The better you know your starter, the easier it becomes to work with its rhythm rather than against it. You learn when it responds quickly, when it needs more time and how long it usually takes to move from a cold, quiet culture to an active starter ready for baking. Eventually, you stop thinking in terms of rigid schedules and start paying attention to a pattern that feels almost intuitive.
Somewhere along the way, it becomes less like a routine you have to maintain and more like a kind of collaboration. You decide when you want to bake. Your starter tells you how much time it needs.
It does not need you every day. Just often enough.
