Sourdough Starter Alcohol Smell: Understanding the Essence of Fermentation
The distinct alcohol smell emanating from a sourdough starter is a testament to the vibrant microbial ecosystem within. This aroma arises from the fermentation process, where yeast and bacteria convert the sugars present in flour and water into lactic acid and ethanol (alcohol). A whiff of this characteristic scent signals a healthy and active starter, essential for baking flavorful and tangy sourdough bread.
