Top Jar Recommendations for Cultivating a Sourdough Starter in 2024

Best Jars for a Sourdough Starter in 2024

Baking sourdough bread is a delightful culinary endeavor that requires meticulous attention to detail. At the heart of a successful sourdough loaf is the starter, which relies on wild yeast grown from a simple mixture of water and flour. When it comes to choosing the right jar for your sourdough starter, there are several factors to consider. In this article, we will explore the seven best jars for a sourdough starter in 2023, highlighting their features and benefits. By understanding the pros and cons of each option, you can make an informed decision and become a master sourdough baker in no time.

Types of sourdough starter containers

Before delving into the best jars for a sourdough starter, it is important to understand the different types of containers available. Ideally, a tall jar or container is preferred over a short and squat one. A tall jar allows for easier measurement and monitoring of the starter’s growth and is more visually appealing. The three main types of containers used for sourdough starters are glass, plastic, and stoneware.

Glass starter jars

Glass and plastic jars are the most commonly used containers for growing sourdough starters. Glass jars, although slightly more expensive than their plastic counterparts, offer the advantage of being visually transparent, allowing you to track the growth patterns of your starter. They also provide a non-reactive environment for the yeast culture to thrive. However, glass jars have a higher risk of breakage than plastic jars, although they are by no means fragile.

Plastic starter jars

Plastic jars are a popular choice because of their affordability and accessibility. They are readily available in most households or can be purchased inexpensively for specific yeast culture needs. However, it is important to note that certain health risks may be associated with lower quality plastic jars. In addition, plastic jars are more prone to discoloration, warping, and scratching over time.

Sourdough Crocks

An alternative to glass and plastic jars is stoneware. Stoneware sourdough jars are heavier and more durable. They are often preferred by sourdough enthusiasts because they provide a non-reactive environment for the yeast culture. Stoneware also provides better temperature control than glass or plastic containers. The stable temperature inside the crock promotes optimal bacterial growth, helping to build a starter faster and with better results. However, one drawback of stoneware containers is that their opaque nature makes it difficult to measure growth without opening the lid.


What type of container is best for growing a sourdough starter?

Ideally, a tall, transparent glass jar or non-reactive stoneware pot is recommended for optimal growth and easy monitoring of the starter’s progress.

Can I use a plastic jar for my sourdough starter?

Yes, plastic jars can be used, but it’s important to choose high quality, food-safe plastic jars to avoid potential health risks and to ensure the longevity of the container.

Why is it important to choose a non-reactive container for a sourdough starter?

A non-reactive container, such as glass or stoneware, prevents unwanted interactions between the acidic nature of the starter and the container material, ensuring a healthy fermentation process.

What size jar should I choose for my sourdough starter?

It’s recommended that you choose a jar with a capacity of at least 1 quart (32 ounces) to allow enough room for the starter to expand during fermentation without overflowing.

Can I use an airtight jar for my sourdough starter?

While an airtight seal can be helpful in the early stages of fermentation, it’s important to allow some airflow to prevent excessive pressure build-up. Consider using a jar with a loose fitting lid or a jar with a removable seal to regulate airflow.

How should I clean and maintain my sourdough starter jar?

To clean the jar, wash it in warm soapy water and rinse thoroughly. Avoid using harsh chemicals or abrasive scourers that could damage the container. Discard and feed your sourdough starter regularly and clean the jar regularly to prevent the build-up of dried dough or residue.
