Aldi relabels sourdough loaf after complaint over rye content
Aldi is changing a loaf from Rye Dark Sourdough to Wheat & Rye Dark Sourdough after a complaint flagged that the bread was mainly wheat and only 31% rye.
What counts as sourdough on a shelf label is more than a branding choice, and Aldi’s relabeling of its dark rye loaf shows why the distinction matters. After a complaint from the Real Bread Campaign, the supermarket began changing the product name from Rye Dark Sourdough to Wheat & Rye Dark Sourdough, reflecting a recipe that contained just 31% rye flour and used refined wheat flour as the main ingredient.
The dispute moved quickly from the bakery aisle to trading standards. The Real Bread Campaign first raised concerns with Aldi in early 2026, then escalated the case when it said the product name and ingredient declaration did not clearly match what was inside the loaf. Aldi replied on 10 February 2026, saying it viewed the name as a customary description and did not need a separate quantitative ingredient declaration for rye. The campaign rejected that position, arguing that rye had been pushed to the front of the branding without a clear disclosure of how much of the flour blend it actually made up.
By 11 May 2026, a London Borough of Tower Hamlets trading standards official said amendments were already in progress on the line, and the relabeling was underway before the report was published on 12 May 2026. That small shift from Rye Dark Sourdough to Wheat & Rye Dark Sourdough carries a bigger message for shoppers who buy sourdough for its process as much as its taste. Naturally leavened bread is one thing; a product that borrows the word sourdough while leaning mainly on wheat flour and baker’s yeast-style marketing language is another.
The case fits into a longer campaign against bread labels that sound more artisan than the recipe justifies. The Real Bread Campaign was officially launched in November 2008 and has lobbied since spring 2009 for updated bread composition, labelling and marketing standards through its proposed Honest Crust Act. It also launched Sourdough September in 2013 to push genuine sourdough baking and buying, especially from small, independent bakeries.
Aldi’s relabeling echoed a similar case involving Lidl in December 2023, when a “Sourdough crusty rye bloomer” was changed to “Crusty Wheat & Rye Bloomer” after a complaint from the same campaign. For sourdough bakers and buyers, the line is now even clearer: if rye is only part of the mix, and sourdough is only part of the story, the name on the pack has to say so.
