4 Different Containers For Your Sourdough Starter

Homemade Sourdough Starter | theclevercarrot.com

Meet Dillon, my sourdough starter.

It’s an offspring from an 8 year old Australian starter, which was a gift from my friend Celia (you’ll read all about it in my book!) Together, we created Artisan Sourdough Made Simple. 

If you’re new to sourdough, a starter is a live fermented culture of flour and water. Once it becomes all bubbly and active a small portion is added to your bread dough to make it rise- no commercial yeast is required. You’ll find more detailed writing and supplemental information in my book (trust me, I could go on and on!) but for now, all you need to know is this: without a starter the whole concept of sourdough baking would not exist.

So, what type of container is best for your starter? Does it even matter? 

In my experience, sourdough storage depends on the baker. And to be honest, I’ve never heard of a container that’s necessarily good or bad, but I’m sure you’ll get all kinds of opinions if you ask around! In fact, I love when people post their starters to Instagram or to their blog. It’s fun to see the variety.

Here are four simple options to get you started:

1.) Glass Jar

This is my personal favorite. Over the years I’ve moved away from plastic containers and Tupperware out of choice. I like glass. It’s easy to clean and you don’t have to worry about any weird chemicals leaching into your starter.

Also, because glass is clear you can see everything that’s going on inside (all the bubbles, foamy stuff, any liquid… ). This instant visual access is super important when getting to know your starter and what you can do to fix it, if necessary. I’ll never forget: over the summer a fleet of fruit flies decided to take up residence in my jar. Had I been using a solid container of some sort, I never would’ve seen them! Gross, I know.

There are all types of glass jars you can choose from: mason jars, jam jars, latch top jars, canning jars with those metal ring tops you can never find… it’s up to you.

Regarding jar size, it’s all relative to the amount of starter you currently have or want to maintain in the future. Your starter will grow to at least double in size, sometimes more, and you’ll need a jar to accommodate this. You can cover it loosely with a lid, plastic wrap, or even a small cloth. I go back and forth depending on my mood.

Keep in mind, the jar might burst if the lid is on too tight which means you’ll run the risk of getting glass shards in the mixture. This happened to me once and I had to throw the whole thing out.

2.) Plastic Container

Although my preference is glass, I first started with a plastic container. I had no problems with it at all. From memory, I think it was a small, random BPA-free Tupperware container I unearthed from the depths of my kitchen cabinet.

As mentioned above, I moved away from plastic. But there’s another reason why I made the switch: size.

Most plastic containers (unless you’re using a Chinese quart container for soup) are not tall. They’re wide and squat. I didn’t like this because it was hard to tell when my starter had doubled in size, which is a visual benchmark for when it’s ready to use.

In comparison to glass however, plastic doesn’t break; it only melts should you leave it on the bottom rack of your dishwasher ;)

3.) Pint Jar

When all of my glass jars are dirty or being used for something else, I use a pint glass! Yes, the kind you drink beer from at a bar. These are perfect for sourdough starters. They are nice and tall, and you can cover the top with a cloth or plastic wrap. Any type of large and tall glass will do. I have a stash in my kitchen.

4.) Stoneware Crock

Personally, I’ve never used this. King Arthur Flour offers large sourdough crocks which seem pretty popular. The selling point is that its material is non-reactive and the crock itself is easy to identify, so you won’t accidentally throw it out because it looks like pancake batter in a jar (see option #3). Unlike glass, I’m pretty sure these crocks do not burst easily either. Regardless, I still prefer clear containers so I can monitor what’s going on inside.

Whatever container you choose, the trick is to play around to see what you like.

You might begin with a certain jar only to realize that it’s particularly annoying to clean, which then motivates you to switch to something else. And this is okay. Plus, overtime your starter will form crusty bits of dried flour at the top of the container and near the lid. When this happens (and it will), you’ll need to change it out anyway. So get creative and experiment with what you have!

So what about you? What type of container do you use for your sourdough starter?

    My sourdough, Dan… lives in the exact same type of container you showed on your first picture

    when I refresh it, I either use empty yogurt containers, or mason jars – I refresh several times in smaller volumes, then the final refreshment pre-bake I normally go for the empty yogurt container because it is larger

    a small portion goes into storage in the glass jar like yours.

    I keep two starters going, one as a reserve, after once feeding with milk rather than water by mistake.. I keep them in those plastic basins with clip on lids, which have three tiny holes in the top, they are sold to cook steamed puddings in. I have considered glass, but was concerned about the lids but also that I might drop them getting them in and out of the fridge, should they be really cold or have slight condensation. Maybe I worry unduly.

    Ciao amica,

    I am with you on glass, most importantly because it is non-reactive and does not degrade. The visibility of clear glass is also a plus. Although some plastics are listed as stable and food-safe, others are not and are subject to outgassing and degrading. I have been shocked to see how Tupperware degrades over time. There can be no doubt that glass is the safest from a chemical standpoint.

    There is, however one caveat. For those of us who are aging glass (and stoneware along with it) presents a set of hazards all its own. Far heavier than plastic, it is easy to drop, especially if one is beset with arthritis, weakness, and other “grab & hold” issues. When glass hits the floor it is subject to shattering, another serious hazard.

    Again, congratulations on your newest volume, and I send my best wishes for great success!

    Hi! This question is more related to the starter itself. I’ve followed your sourdough recipe in the past with much success! I recently moved and had to make a new starter about a month ago, and was planning to make bread in about a week. But my starter seems a little off… It is very bubbly and forms a little hooch liquid on top rather quickly (12-18 hrs), but doesn’t seem to be rising. It is also a bit runnier/thinner than I’m used to. My kitchen is usually about 65 degrees. What am I doing wrong?? (I realize I maybe should have asked this question under the sourdough recipe post, so please forgive me!)

      Hi Samantha!

      Sourdough starters will change texture from time to time, which is completely normal. Luckily, it’s very easy to fix!

      First, the liquid on the top of your starter is an indication that it needs to be fed. It’s very common to see this liquid (technical term: hooch) so don’t be surprised if you see it again in the future. Now, because your starter is runnier than usual, it sounds like there’s too much water in it to begin with. So here’s what you do: pour off some of the starter to get rid of the liquid, and then give it a feed. If it’s still runny, just add more flour until the consistency is similar to plain yogurt or a slightly thick pancake batter. Place it in a warm spot (65 F is fine; just keep it away from drafts) and wait for it to rise. It might take a few feeds for it to double in size, but be patient. It will happen. Hope this info helps :)

    What size jar is this in the photo? I want to make sure mine is big enough :) Do you store you starter in this type of jar? I just received your new cookbook, and I can’t stop looking through it! It is just beautiful.

    My sour dough starter, which I have not named yet, will be 3 years old in November. I first started out with potato water, but somehow that didn’t work for me. Maybe it wasn’t concentrated enough, but the starter just didn’t rise (read about that in the WSJ). I use King Arthur’s crock pot. The lid shouldn’t be tight, and the reason for that is the starter absorbs the yeast from the air in the kitchen. It was difficult for me to comprehend that this is really happening. I learned it from a rather scientific book, written by Samuel Fromartz. The book is called In Search Of The Perfect Loaf. It takes my started about 8 hours to be fully risen. And it also gave me trouble a couple of times, especially during hot summer days. After a little bit of experimenting I was able to rescue it each time. Baking bread this way is a lot of work, but how fulfilling to taste a wonderful home baked Artisan bread.

    I was just going to ask you this question!! My starter, Flor (short for Florida where it originated) is housed currently in a mason jar. The glass works well for me too, however, I move it back and forth in between different mason jars as I’m cleaning it (when the dried flour gets stuck at the top). Good to read others are experiencing the same things and good to hear I’m doing it right?! :)

      Hi Amy! This is exactly what I do! No matter what container you put your starter in, it will eventually get crusty. It’s always good to have some back up jars. Thanks for sharing your experience!
