Consumer watchdog Which? has named Co-op Irresistible Hand-Finished White Sourdough as the best supermarket sourdough loaf, outperforming popular branded options like Jason's. In a blind taste test involving 71 panellists, the Co-op loaf scored 73% out of 100, praised for its perfect crust and airy yet firm texture. Priced at £2.65, it contains yoghurt, yeast and semolina.
Tesco Finest White Sourdough Loaf came second with 72%, commended for its chewy texture and robust tangy flavour. At £1.95, it offers a more affordable option. Morrisons Best White Sourdough Sliced Half Boule secured third place with 63%, also priced at £1.95, though some tasters found it bland or overly chewy.
Jason's, a well-known brand, failed to make the top three, scoring only 62%. Critics said the bread was too soft, and at £2.20 for a 450g loaf, it was also deemed expensive. The lowest-rated was Waitrose No. 1 White Sourdough Bread, scoring 59%, with testers criticising its lacklustre flavour and dense texture.
