Sourdough bread has firmly cemented its place in British households, now accounting for one in every 13 bread products sold in the UK. This rise in popularity is reflected in significant sales growth at major supermarkets, with Tesco reporting a surge of more than 40% in volume demand over the past year alone. The supermarket now sells over 40 million sourdough products annually and has expanded its range to include various options such as loaves, baguettes, rolls, and crumpets. Most recently, Tesco introduced its first-ever sourdough baguette to meet diversified consumer preferences.

The surging popularity of sourdough bread can be attributed to several factors. Its dense, hard-crusted texture makes it ideal for toasting, while its versatile flavour profile serves as a perfect base for trendy toppings like smashed avocado. Shoppers are increasingly appreciating sourdough not just as a sandwich staple but as a complex and savoury food experience in its own right. Tesco bakery buyer Amelia Roberts highlighted this trend, noting that sourdough is no longer just a basic bread but a product to be savoured for its variety of flavours and textures.

Key suppliers have played a crucial role in making sourdough more accessible to a broader market. Leicestershire-based Quality Food Award-winner Jason’s Sourdough, now the fourth largest bread brand in the UK and the number one dedicated sourdough brand, offers market-leading value with prices significantly lower than many competitors. Owner and Master Baker Jason Geary explained that their sourdough products contain no additives, preservatives, yeast, seed oils, emulsifiers, or artificial ingredients, appealing to consumer demands for cleaner, simpler foods. This commitment to quality and affordability has led to impressive sales figures, with Jason’s Sourdough now selling around one million loaves each week and available in nearly 3,000 supermarkets across the country.

The broader trend towards speciality breads in the UK supports this growth. Data reveals that 29% of consumers seek out sourdough when dining out, showing a strong preference for quality, artisanal products both inside and outside the home. This increasing demand for premium bread varieties is driving UK spending on sourdough to £58.5 million over the past year, marking a 10.7% increase compared to the previous year. Jason’s Sourdough brand alone reported a 132% value growth over the last year, underscoring the robust market appetite for speciality bread.

The success of Jason’s Sourdough has prompted significant expansion, with the company investing £35 million in a new 95,000 square foot manufacturing facility to double production capacity. This move follows a pattern of consecutive years of doubling sales growth, positioning the brand prominently behind traditional bread giants in the market. Such developments indicate that sourdough's rise is not a passing trend but a fundamental shift in British bread consumption patterns driven by changing tastes and increasing consumer desire for authenticity and quality.
