What is a sourdough starter?
A sourdough starter is used in bread-making. It provides better flavor, aside from making the bread fluffy and light. Bakers describe sourdough starters as an ingredient that “breathes life to bread”.
Chemically, sourdough starters have yeast microbes that consume sugars on the flour. As the microbes digest the sugars, they release carbon dioxide. In turn, the carbon dioxide produces bubbles that will make the bread fluffier and lighter. As the name suggests, the sourdough starter ignites the bread to become the fluffy treat that it is.
To create a sourdough starter, you only need to mix flour and water. The wild yeast in the air will do its job as long as you keep the container jar lightly covered. Some use a cloth or a plastic that’s been placed lightly on the lid. It should be closed lightly to let air in but sealed enough to prevent insects from getting into your starter.
Overall, sourdough starters need to ferment for 7 days before it’s ready to use. Some will take up to 2 weeks to become active.
After that, you need to keep feeding your sourdough starter to keep it active. The food is made of water and flour. Take note that you need to discard half a cup of the starter before feeding it.
Make sure that you’re using a reliable jar for your sourdough to last long. The following are five of the best sets/pieces I swear by.

How to choose the best jar for sourdough starter
When shopping for sourdough starter jars, you don’t really have to rack your mind. Here are the important points to consider to keep it simple:
✔️Material
Make sure that you’re getting jars with BPA-free glass. This is very important since you don’t want chemicals leaching into your sourdough starter. Also, glass jars let you see the starter expand and ferment without the need to open the lid too often.
You can also consider using ceramic jars if you’re worried about glass shards. This works, but you won’t see the starter from the outside.
Aside from that, make sure that the glass material is thick and not easily chipped. From time to time, it’s unavoidable to clunk these jars on hard surfaces. A durable jar should endure these bumps. You should still remember that glass jars aren’t invincible, so you should practice caution when handling it.
✔️Lid type
Glass jars are fitted with two types of lids: classic metal lids and clamp locks. Metal lids are foolproof options since it’s easy to put on and off the jar. You can also control how tight the lid will close since it has a thread that matches the jar’s lip.
On the other hand, clamp-style jars are also popular. This has a metal wire that shuts the lid tightly, so air won’t get in. This will work for sourdough starters, too, as long as you remove the silicone seal around the jar’s rim. This will prevent a tight seal that will deprive your sourdough starter of its much needed wild yeast from the air.
✔️Size and capacity
Next, it’s important to get the right jar size for the amount of sourdough starter you’re planning to make. Take note that sourdough starters will expand, so there should be enough space on the jar for this. Otherwise, the lid may pop off, or the jar will shatter if it’s not large enough to house the amount of starter you prepared.
Glass jars are available in a wide range of sizes, ranging from 125 ml to 3 liters. You can easily choose one that matches your needs.
Frequently Asked Questions
Q: Can my sourdough starter go bad?
A: Even if it’s a fermented substance, sourdough starters can still go bad. You need to store it properly to prevent the starter from spoiling. Always check for the presence of molds that usually manifests in color orange or pink streaks. Sourdough starters with molds should be disposed of and never used for bread-making.
Q: Why does my sourdough starter have water on top?
A: This is considered normal and a sign that the starter needs to be fed. The liquid you’re seeing on the surface is called ‘hooch’, which is basically alcohol accumulation due to wild yeast fermentation. A sourdough starter that’s not fed properly will have a blackish surface liquid. This isn’t always a sign of starter gone bad. You just need to care for it better with regular feeding and scooping out half a cup of old ferments.
Q: Can I add a little yeast to my sourdough starter?
A: Yes, you can add a small amount of commercial yeast to your sourdough starter to give it a boost. However, you should remember that the yeast will reduce the sour flavor of the bread. It’s a shortcut to fermentation, but it will not give the authentic sour bread flavor.
