What Happens To Sourdough Starter In The Fridge?

When you store your sourdough starter in the fridge, the cold temperature will slow down the fermentation process and put the starter to sleep. The yeast in the starter will basically go to sleep while the bacteria will continue to work. They will still eat and make your starter rise, but it will happen extremely slowly. Your fridge needs to be around 3C to ensure that the fermentation process slows down effectively. Even when stored in the fridge, your starter will still rise and fall and even produce hooch if left in there for a very long time.

Benefits of Storing Sourdough Starter in the Fridge

Storing your sourdough starter in the fridge can offer a range of benefits that can make your baking routine more efficient and less demanding. Here are some of the advantages of keeping your sourdough starter in the fridge:

• Reduced feeding frequency: When stored in the fridge, your sourdough starter can go without being fed for up to a week or even longer, depending on the temperature of your fridge. This means you don’t have to feed it every day, which can save you time and flour.
• Less flour consumption: A sourdough starter in the fridge uses less flour to maintain, as it is not as active as a starter kept at room temperature. This can help you save on flour and reduce waste.
• Convenient for busy schedules: Storing your sourdough starter in the fridge allows you to leave it unattended for longer periods of time, making it easier to manage your baking routine around your busy schedule.
• Establish a baking routine: By keeping your sourdough starter in the fridge, you can establish a regular baking routine that fits your schedule. This can help you plan ahead and avoid last-minute baking emergencies.
• Enhanced flavor: Storing your sourdough starter in the fridge can help you develop a more sour flavor in your bread, as the cooler temperatures slow down the fermentation process and allow for the development of more complex flavors.
• Vacation-friendly: Storing your sourdough starter in the fridge allows you to take a break from baking without worrying about your starter. You can even freeze your sourdough starter if you need to take a longer break.

Overall, storing your sourdough starter in the fridge can be a convenient and practical way to manage your baking routine while still producing delicious and flavorful bread. However, if you have a new starter, it is important to approach the fridge with caution, as it may not be mature enough to handle the cooler temperatures.

How To Maintain Sourdough Starter in the Fridge

Maintaining your sourdough starter in the fridge is an easy way to keep it fresh between baking sessions. Here are some steps to follow to keep your sourdough starter active and healthy:

1. Feeding: Before putting your sourdough starter in the fridge, feed it with a 1:2:2 ratio. This means feeding one part of sourdough starter to two parts of flour and two parts of water. For example, if you have 25g of sourdough starter, feed it with 50g of flour and 50g of water. This ratio ensures that your starter has enough food while in the fridge.
2. Mixing: Mix the sourdough starter, flour, and water together until well combined.
3. Placing in the Fridge: Place the lid on the jar and put it in the fridge. You don’t need to wait for the starter to double before putting it in the fridge.
4. Feeding Schedule: Feed your sourdough starter at least once a fortnight, always discarding before feeding. You don’t need to leave it out, you can feed it and put it straight back in the fridge if you aren’t going to bake with it.
5. Going on Holidays: If you are going on holidays, your starter will survive longer than a fortnight without a feed.
6. Refresh: If you want to refresh your sourdough starter, take it out of the fridge, scrape off any brown liquid, activate it with some flour and water, and leave it at room temperature for 12 hours before putting it back in the fridge.
7. Water: If your tap water contains chlorine or chloramine, use filtered water or leave tap water out overnight before using it to feed your starter.
8. Flour: You can use all-purpose flour, bread flour, or whole wheat flour to feed your starter.
9. Hydration: The hydration level of your starter depends on the feeding ratio and the type of flour used. A 1:2:2 feeding ratio results in a 100% hydration starter.

By following these steps, you can maintain your sourdough starter in the fridge and keep it healthy and active for your next baking session.

When Is Your Sourdough Starter Mature Enough For the Fridge?

If you’re new to sourdough baking, you might be wondering when your starter is mature enough to be stored in the fridge. A mature starter is essential for baking bread with good flavor and rise. Here are some things to consider before putting your starter in the fridge:

• How old is your starter? Is it less than 8 weeks old?
• Does your starter double within 2-4 hours after a feed?
• Are you prepared to feed your starter a few times before you want to bake to ensure it’s strong enough to bake with?

It’s recommended to keep your starter at room temperature and feed it twice a day until it’s mature, which can take at least 6 to 8 weeks, usually longer. This allows your starter to develop a good flavor profile and a strong yeast colony that will rise your bread easily.

Putting your starter in the fridge too soon will not allow it to reach maturity for a long time as the fridge puts it to sleep. If your starter is less than 8 weeks old, it’s not mature enough for the fridge. Leaving it on the counter and feeding it daily is always the better option.

A mature starter is bubbly, active, and has a pleasant aroma. It contains natural yeast and bacteria that work together to create lactic acid, which gives sourdough bread its tangy flavor. When your starter is at its peak, it will have expanded and risen, indicating that it’s alive and growing.

In summary, only put your mature starter in the fridge when it’s strong enough to bake with and you’re prepared to feed it a few times before baking. By following these guidelines, you’ll have a healthy and delicious sourdough starter that will last for years.

Can I Use Sourdough Starter Straight From The Fridge?

Technically, you can use your sourdough starter straight from the fridge. However, it is not advisable to do so because you will be using a sleepy, inactive starter. This can cause many sourdough bread problems. It’s much better to wake your starter up before you bake. The way you do this will depend on how long your starter has been in the fridge and how it responds to being woken up.

Less Than 2 Weeks:

If you fed your starter 1:2:2 before placing it into the fridge and it has been in the fridge for less than 2 weeks, you shouldn’t need to do much to wake it up. If it’s only been a few days, just placing the jar on the counter and letting it warm up should be enough (this is because the yeast and bacteria will not have consumed all of the food yet). So bringing the starter to room temp and seeing if it rises is the first step. If the starter rises, you can generally bake with it as is. If it was closer to 2 weeks, we advise discarding and feeding at least once before you bake.

More Than 2 Weeks:

If your starter has been in the fridge for more than 2 weeks (but less than 6 months), it will be sleepy, but it shouldn’t take much to get it going. Take it out of the fridge and take 25g of the cold starter. Place it into a clean jar and feed with 50g of flour and 50g of water. Let it double. Then repeat. If it doesn’t double, repeat the process until it does. Your starter is ready to bake with when it’s doubled, spongy, and has a slightly domed top. It needs to be bubbly and full of life!

6 Months +

If your starter has been in the fridge for more than 6 months, it will more than likely be in bad shape. It may have a layer of black or dark purple hooch and it will smell horrendous. However, as long as there’s no mold present, you can revive the sourdough starter easily. Here’s what you need to do:

1. Take 25g of the cold starter and place it into a clean jar.
2. Add 50g of flour and 50g of water to the jar and mix well.
3. Let it sit for 12 hours.
4. Discard all but 25g of the mixture.
5. Add 50g of flour and 50g of water to the jar and mix well.
6. Let it sit for 12 hours.
7. Repeat steps 4-6 until the starter is bubbly and full of life.

Reviving an old sourdough starter can take some time, but it’s worth it to have a healthy, active starter for your bread baking needs.

What Happens If You Leave Your Sourdough Starter in the Fridge for a Long Time?

Your sourdough starter will survive for quite some time in the fridge, even if you forget to feed it or you go away. You might notice that it has developed hooch, which means it’s hungry and has become quite sour. However, you can easily revive it by discarding and feeding it when you’re ready to use it again.

It’s worth noting that people have been known to revive a starter from the fridge after two years or more. So, as long as there is no mold, there is always hope.

If you’re worried about your sourdough starter, you can always check for mold. If you see any mold, you should remove the moldy parts and feed the remaining starter. However, if the mold has spread throughout the starter, it’s best to discard it and start again.

Something to keep in mind is that you never need to add anything to your sourdough starter. You might hear about adding pineapple juice or raisin water to get your starter going, but there is no need to do this.

If your starter isn’t rising after being in the fridge for a long time, you can try some of these tips to boost it:

• Take it out of the fridge and let it come to room temperature before feeding it.
• Feed it with a higher ratio of flour to water.
• Feed it more frequently for a few days to give it a boost.

Remember, you should never use your sourdough starter straight from the fridge. You need to take it out, discard and feed it, then use it at its peak when it doubles in size. It will be sleeping in the fridge, and if you waited for it to double before you put it in, then it’s used all its food and will be past its peak.

In terms of how long your sourdough starter will last in the fridge, if you’ve fed it before placing it in the fridge, it should be able to last two weeks comfortably without feeding. The starter will still be in good condition if just left for this amount of time. It will last much longer in the fridge, even years, without food. However, when you take it out of the fridge, it will need a lot of nurturing to get it back to peak condition. You’ll need to follow these tips to reactivate your old sourdough starter.
