National Sourdough Bread Day 2023: National Sourdough Bread Day is observed annually on April 1 to recognise the lengthy history of sourdough bread production. The frequently crusty loaf, with its chewy texture and strong acidic tang, is regarded as one of the most distinctive tasting breads available.

Did you know that French bakers introduced the fermentation process that lends bread its characteristic sour flavour to North America? French chemist and microbiologist Louis Pasteur discovered the microorganisms that cause fermentation and impart flavour to sourdough bread. This discovery led to the commercial production of a special yeast for sourdough bread, which then spread throughout the country.


The history of making sourdough bread can be traced back to the gold rush of the 1800s, which drew miners from all over the world to California, along with their baker relatives. Local legend attributes the bread to Pyrenean Basques who settled in San Francisco during the gold rush.

Traditionally, the bread is produced by fermenting the dough with lactobacilli and yeasts. In a typical sourdough bread production, lactobacilli outnumber yeasts by a ratio of 100 to 1 and are responsible for the production of acidic acids.

It begins when an ecosystem begins to form as flour and water are combined to create starter dough. As the dough’s pH decreases, enzymes in the flour convert carbohydrates into sugars, and bacteria convert these sugars into lactic and acetic acid. The majority of microorganisms perish at this juncture. Before yeasts begin to convert carbohydrates into carbon dioxide and ethanol, which is frequently accompanied by gas bubbles and fruity fermentation odors, the dough is ready for baking.

San Francisco’s traditional bread is sourdough, and it remains a part of the state’s culture. In fact, its rich history is reflected in the appellation of the San Francisco 49ers’ mascot, ‘Sourdough Sam.’

During the Gold Rush, the term’sourdough’ became the alias for gold prospectors because the bread was so prevalent. It continues to be a staple on the menus of many of the state’s establishments, maintaining its popularity.

Five essential facts about sourdough bread

It is characterised by an acidic flavour and microbes.

The characteristic tangy flavour of sourdough results from the fermentation of dough using Lactobacillus bacteria and yeast.

It is ideal for diabetic patients.

Low-glycemic foods, such as sourdough, serve to regulate blood sugar levels.

It does not require preservatives

The fermentation process of sourdough bread eliminates the need for a preservative to increase its shelf life.

Bread, yogurt, and cheese.

The lactobacilli bacteria responsible for the acidic flavour of sourdough are related to the bacteria found in yoghurt and cheese.

Lactobacilli bacteria prolongs shelf life.

Microbiologists believe lactobacilli bacteria also extend the shelf life of sourdough bread.
