Is That Really Sourdough?

Let’s be honest- sourdough is having a moment (as it should). You can find it everywhere now, from grocery store shelves to trendy cafes. But here’s the thing most people don’t realize: a lot of what’s labeled “sourdough” isn’t truly sourdough.

What Is Real Sourdough?

At its core, authentic sourdough is incredibly simple.
It’s made with just four ingredients:
Flour, water, salt, and sourdough starter.
The starter itself is a mix of flour and water that’s been naturally fermented over time. This slow fermentation allows wild yeasts and beneficial bacteria to develop, giving real sourdough its classic tang, texture, and digestibility.

So What’s the Deal with Store-Bought Sourdough?

If you’ve ever picked up a loaf of “sourdough” from the grocery store and flipped it over, you’ve probably seen a long list of ingredients—things like sugar, oils, preservatives, and most importantly: yeast.

When commercial yeast is added, the bread rises quickly. It skips the fermentation process that gives sourdough its unique flavor and health benefits. So while it might look like sourdough on the outside, it doesn’t have the same depth, character, or simplicity.

Why It Matters

Of course, if you’re in a rush, that store-bought version will do the trick- but sometimes, the more you know, the better choices you can make.

When you buy from a local baker, you’re getting real sourdough, made slowly and intentionally, just the way it’s meant to be. No shortcuts. No additives. Just honest, fermented goodness you can taste in every bite.
