What is the best container to store sourdough? Sourdough bread has earned its place as a favorite among bakers, thanks to its distinct flavor, texture, and health benefits. However, one of the most crucial steps to successful sourdough baking is maintaining a healthy sourdough starter. The starter is the backbone of your bread, and its quality largely depends on how you care for it, including storing it in the right container.
Choosing the best container to store your sourdough starter is critical for its health and productivity. The right container will allow for proper fermentation, enable easy feeding, and support the growth of your starter. In this guide, we’ll explore the factors you should consider when selecting a container for your sourdough starter, as well as some of the top container options available today.

Why the Right Container Matters for Sourdough Starter
The container you use for storing your sourdough starter can significantly influence its development. Sourdough starters are living cultures made up of wild yeast and bacteria, and like any living organism, they require certain conditions to thrive. These conditions are largely dependent on the environment they are kept in, including the container.
Choosing a container that is the right size, material, and ventilation level will help your sourdough starter flourish and improve the chances of your bread rising properly. An improper container, on the other hand, could lead to stagnant or overly acidic environments, hindering the starter’s activity.
The storage container also serves a more practical purpose: it must be easy to clean, maintain, and monitor the starter’s progress over time. A poorly designed container may make it difficult to see if the starter is growing or if it needs feeding. This is why selecting a container with the appropriate capacity, material, and features is vital for long-term sourdough success.
Key Features to Look for in a Sourdough Starter Container
When selecting a container for your sourdough starter, you should consider several factors that will directly affect the health and productivity of your starter. The key features to look for include:
1. Capacity and Size
The size of your container is one of the most important aspects to consider. A starter needs enough space to grow, especially after being fed. As your starter feeds on the flour and water you provide, it will double or even triple in size. If your container is too small, it can overflow, leading to a mess and potentially contaminating the starter. Conversely, if the container is too large, the starter may not have enough nutrients to grow effectively.
- Ideal size: A container that holds between 2 to 4 cups (500 ml to 1 liter) is usually perfect for most home bakers. It gives enough space for the starter to rise and allows you to monitor its progress easily.

2. Material of the Container
The material of the container affects the temperature regulation, ease of cleaning, and non-reactivity with the starter. Let’s take a look at the most common materials used for sourdough starter containers:
- Plastic Containers: Plastic is affordable, durable, and widely available. It’s a good choice for beginners since it’s less likely to break if dropped. However, plastic can sometimes absorb odors over time, especially if the container is used for different types of food storage. If you opt for plastic, make sure the container is BPA-free and non-reactive.
- Glass Containers: Glass is an excellent choice for sourdough starters because it is non-reactive and won’t interfere with the acidity or flavor of the starter. It also allows you to clearly monitor the growth of your starter. Glass containers are dishwasher-safe, but they can break easily, so be cautious when handling them.
- Stoneware or Ceramic Containers: Stoneware is a heavier option that can help regulate temperature. It retains warmth and helps maintain a steady fermentation environment for the starter. However, stoneware containers are often not transparent, making it difficult to observe the starter’s progress without opening the lid. If you prefer a stylish option that balances functionality and aesthetics, this could be the right choice for you.

3. Breathability vs. Airtightness
One of the most critical factors in selecting the right container for your sourdough starter is ensuring the container isn’t airtight. While airtight containers can keep moisture out, they also trap gases produced by the fermentation process, potentially causing the container to burst. On the other hand, a container with too much airflow could dry out your starter.
- Lid type: You’ll need a container with a lid that isn’t completely sealed. A lid that loosely fits or one that can be covered with a cloth is ideal. If using a glass container, some people use a rubber band and a piece of parchment paper to keep things covered while still allowing air circulation.
Top Containers for Storing Sourdough Starter
Several containers on the market are specifically designed to store sourdough starters. Here’s a rundown of the best options available for home bakers:
1. Glass Containers
- Le Creuset Stoneware Canister: This stoneware container is an attractive option for those who want both style and function. It features a wooden lid that ensures the starter stays fresh while allowing air to escape. Stoneware’s natural properties help regulate the temperature, making it a great option for long-term starter storage.
- Cambro 2-Quart Translucent Round Container: If you’re looking for durability and functionality, this transparent container is an excellent choice. It’s perfect for monitoring your starter’s growth, and the measurement markings on the side make tracking the rise easy. Cambro containers are also known for their heavy-duty, long-lasting quality.

The plastic material is durable and shatterproof, making it an excellent option for those with young children or in busy kitchens.
3. Stoneware and Ceramic Containers
- Le Creuset Stoneware Crock: If you prefer a ceramic option that looks great on the countertop, this stoneware crock is perfect. It comes with a wooden lid and a silicone seal to prevent any air from entering while still allowing the starter to breathe. The weight and insulation of the stoneware help to maintain a steady temperature.
How to Maintain and Care for Your Sourdough Starter Container
1. Cleaning Your Container
Cleaning your container regularly is crucial to prevent the buildup of bacteria or mold in the starter. It’s essential to thoroughly wash your container to remove any leftover flour and yeast.
- Glass Containers: Glass is easy to clean. You can simply wash them with warm, soapy water, or sterilize them by boiling the container for a few minutes.
- Plastic Containers: Be sure to scrub them thoroughly with hot water. Plastic can absorb odors, so it’s important to ensure they’re properly cleaned between uses.
2. Long-Term Storage Tips
If you don’t bake every day or week, storing your starter in the fridge can help slow down fermentation. Refrigerated starters require less frequent feedings (every two weeks or so), which is ideal for the occasional baker. If you’re going to store your starter for an extended period, freezing it is another option, but be sure to feed it once it thaws to revive the yeast.
