For bread lovers across Britain, the quest for the perfect supermarket sourdough can feel like searching for the Holy Grail. That distinctive tang, the satisfying crust, and the airy crumb - when done right, sourdough transforms any meal. But with every major retailer now offering their own version, how do you know which one deserves a place in your shopping basket?
We embarked on a crust-to-crumb investigation, putting supermarket sourdoughs through their paces to separate the truly artisan from the merely adequate.
What Makes Great Sourdough?
Authentic sourdough isn't just another loaf - it's a labour of love. True sourdough relies on wild yeast and lactobacilli rather than commercial baker's yeast, resulting in that characteristic tangy flavour and complex texture. The best examples showcase:
- Proper fermentation - that distinctive sourdough flavour
- Crisp, substantial crust - audible when you tap it
- Open, irregular crumb - with plenty of air pockets
- Chewy texture - with proper elasticity
The Supermarket Contenders
From budget-friendly options to premium artisan-style loaves, the range available today is staggering. Some supermarkets have invested heavily in proper bakery sections with trained bakers, while others rely on pre-baked imports.
The Surprising Standouts
Several retailers have truly upped their game, offering sourdough that could rival many independent bakeries. These loaves demonstrated proper fermentation times, quality ingredients, and that all-important crust that crackles when squeezed.
Where Some Supermarkets Stumble
Disappointingly, some supermarket 'sourdough' barely deserves the name. These imposters often contain added yeast or commercial raising agents, resulting in a loaf that's sourdough in name only. The tell-tale signs? A uniform, cake-like crumb and lack of that signature tang.
Our Top Performer
One clear winner emerged from our tasting, boasting the perfect balance of tangy flavour, substantial crust, and that satisfying chew that sourdough devotees crave. What set it apart was its authentic fermentation process and quality British flour.
The Budget-Friendly Dark Horse
In a pleasant surprise, one of the most affordable options performed remarkably well, proving that you don't always need to pay premium prices for quality sourdough. This loaf offered excellent value without compromising on flavour or texture.
How to Spot Quality Sourdough
Check the ingredients list - it should be short: flour, water, salt, and starter. Beware of added yeast, vinegar, or preservatives.
Examine the crust - it should be thick and crisp, not soft or uniform.
Feel the weight - good sourdough has a substantial heft for its size.
Look at the crumb - irregular holes and slight variation in colour indicate proper fermentation.
The Verdict
While nothing quite matches buying from your local artisan baker, several supermarkets now offer genuinely excellent sourdough that makes quality bread accessible to everyone. Whether you're making the perfect avocado toast, a bacon sandwich, or simply enjoying it with good butter, the right supermarket sourdough can elevate your everyday eating.
Our investigation proves that with careful selection, you can find outstanding sourdough without making a special trip to the bakery. The great British sourdough revolution has well and truly reached the supermarket aisle.
