For the last few decades, modern diets have slammed fresh bread. According to Nielsen, total bread sales in the United States have been stagnant since 2015, showing little to no growth leading up to 2020. But bread is making a comeback, specifically sourdough bread. A study conducted by Grand View Research saw the market value of sourdough jump from $298.7 million in 2014 to $2.4 billion in 2018. Sales of sourdough bread grew 11.6 percent from 2015 to 2019, to over $325.9 million.
