Sourdough vs Bread:
Which Is Gluten-Free?
The persistent myth: that sourdough fermentation "eats" the gluten. It reduces it, but nowhere near celiac-safe levels — traditional sourdough is still wheat bread.
Heads up: both Sourdough and Bread typically contain gluten — see the safe alternatives below.

Sourdough
No, traditional sourdough bread is NOT gluten-free. While fermentation reduces gluten, it does not eliminate it.
Watch out for:
- The myth that fermentation destroys all gluten
- Restaurant sourdough burgers/sandwiches
- Sourdough starters gifted by friends (wheat-based)
Bread
No, regular bread is made from wheat flour and contains gluten. Many excellent gluten-free bread brands are available.
Watch out for:
- Sourdough is NOT gluten-free despite myths
- Rye bread contains gluten
- "Wheat-free" does not mean "gluten-free"
