Sourdough vs. Supermarket: Spotting the “Sourfaux”
Share
You’ve seen it — a loaf in the grocery store labeled “Artisan Sourdough” for a fraction of the price of a bakery loaf.
It looks the part, but is it genuinely sourdough?
Short answer: not even close.
In the baking world, we call these supermarket impostors Sourfaux. Learning to spot the difference makes you a confident advocate for real, naturally fermented bread.

3 Red Flags of a “Sourfaux” Loaf
-
The “Y” Word
If the ingredients list yeast or baker’s yeast, it’s not real sourdough. True sourdough rises naturally thanks to the wild starter. -
Speedy Additives
Watch for ascorbic acid, amylase, or L-cysteine. These dough conditioners force the bread to rise fast — nature’s timetable be damned. -
The Fake Tang
Some brands add vinegar or fumaric acid to simulate sourness. Real tang comes only from patient fermentation, not shortcuts.
Why the Price Difference?
You’re not just paying for flour — you’re paying for quality crafted over time.
Supermarkets churn out thousands of loaves a day using yeast and chemicals.
At our bakery, we let our wild cultures do their thing over 24+ hours.
It’s slower, more labor-intensive, and yes, it costs more — but the result is a loaf that’s actually real food.
The Bottom Line
Our loaves are designed for the stomach.
Real sourdough takes time, care (and just a little bit of magic).
