Whole Grain Sourdough Bread

Whole grain sourdough bread is a rustic, naturally fermented loaf made using whole grain flour—such as whole wheat, spelt, rye, or a blend—rather than refined white flour. It’s known for its dense, hearty texture and deep, slightly nutty flavour, with a gentle tang that comes from the long fermentation process.

Because it uses the entire grain kernel (bran, germ, and endosperm), whole grain sourdough tends to be richer in fibre, vitamins, and minerals compared to white sourdough. The crust is usually thick and crisp, while the inside (crumb) is chewy, slightly moist, and often irregularly aerated with small to medium holes.

Sourdough bread made with whole grains is especially popular for sandwiches, toast, or served alongside soups and cheeses. It has a more robust, earthy profile than standard white sourdough, making it a favourite for people who enjoy deeper, grain-forward flavours and more filling bread.
