WHY THIS DAY MATTERS

Why We Love Sourdough September

Sourdough is a part of history

Sourdough has been around for centuries and has played a crucial role in the history of many cultures. It was often used as a staple food during tough times and has become a beloved tradition in many households today - making Sourdough September a perfect time to celebrate this delicious bread!

Sourdough is a versatile bread

From toast to sandwiches, sourdough can be used in a variety of ways. Its tangy flavor adds an extra dimension to any dish and it also has a longer shelf life compared to other types of bread.

Sourdough is made through a natural process

Unlike other breads that use commercial yeast, sourdough is made through a natural fermentation process using wild yeast and bacteria. This not only gives the bread its characteristic tangy flavor, but also makes it easier for some people to digest.
