If you love the flavour and tradition of homemade sourdough, the flour you choose is the key ingredient.
At Sourdough by the Sea, we’ve carefully selected Gilchesters Organics Unbleached White Strong Bread Flour – a stoneground wheat flour milled in the UK using traditional methods. This organic bread flour gives sourdough loaves the strength, structure, and flavour they need, while also supporting sustainable farming and local milling.
Why choose organic bread flour for sourdough?
Not all flour is the same. Strong bread flour is essential for sourdough baking, giving the dough enough protein and gluten strength to rise slowly over time. With Gilchesters Organics flour, you’re not only choosing strength but also flavour and sustainability.
- Organic and natural – no bleaching, no unnecessary additives.
- Stoneground wheat flour – traditional milling preserves more nutrients.
- Strong bread flour – perfect for sourdough, artisan loaves, and home baking.
- UK milled – supporting local farmers and environmentally friendly production.

Why stoneground wheat flour makes better sourdough
Stoneground milling is a slower, gentler process compared to modern steel roller mills. It keeps more of the wheat germ and bran intact, giving your flour extra depth, nutrition, and flavour. That’s why this flour produces loaves with a rich taste and an open, satisfying crumb – ideal for sourdough.
When you bake with stoneground organic bread flour, you’re not only making better bread, you’re also supporting traditional food production methods that respect the land and the crop.
Start baking sourdough with flour you can trust
Good sourdough starts with good flour. Whether you’re new to baking and need a sourdough starter kit, or you’re a regular baker looking to buy organic strong bread flour online, these two products give you everything you need.
By choosing Gilchesters Organics flour, you’re helping to keep UK flour mills thriving, supporting organic farming, and reducing your environmental impact – all while enjoying bread that tastes as good as it should.
