Sales value, household purchases, bakery openings and search interest are different measures. A claim that sourdough is “booming” needs a dated metric and a defined product category.
A documented production milestone
The Chorleywood Bread Process was developed in 1961. That is a specific modern breadmaking milestone; it should not be compressed into a vague claim that the Industrial Revolution alone displaced British sourdough.
Market evidence has limits
Official household bread-purchase data cover broader categories than sourdough alone. They cannot establish a sourdough growth rate or explain consumer motives without more detailed evidence. This page does not provide a current sourdough market-size estimate.
What was removed
The earlier claims that Britain’s climate creates a distinctive national fermentation pattern and that health awareness explains a nationwide renaissance were not sufficiently supported. Named bakery reporting and appropriately scoped market data would be needed to develop that story.
