The Science & Art
We are devoted to the use of natural leaven or sourdough starter in our bread. Here are some of the benefits of this traditional microbial transformation:
While modern bread is a dead product of industrial chemistry produced in 2 hours, sourdough is a 24h hour microbial transformation. This ‘pre-digestion’ process changes how your blood sugar and gut react to wheat.
A sourdough starter is a live culture where wild yeasts and lactic acid bacteria live in harmony and support each other, unlike commercial yeast, which is a monoculture, this is a diverse ecosystem.
All grains contain phytic acid, an ‘anti nutrient’ designed to protect the seed. Sourdough fermentation produces phytase – an enzyme that literally dismantles phytic acid. This makes the minerals (like iron and zinc) in the flour bioavailable.
Sourdough bread produces a lower blood sugar spike compared to yeasted bread, making it easier on your metabolism.
The long fermentation process breaks down the complex gluten protein chains, that’s why many people with gluten sensitivity can eat sourdough without bloating or discomfort.
During the long fermentation process the lactic acid bacteria create specialized fibres that act as prebiotics. These fibres survive the high heat of baking and become a fuel for your gut microbiome.
Unlike standard breads made with commercial yeast, authentic sourdough has a uniquely complex flavor profile, best known for its signature "tang" or mild sourness, balanced by deep, earthy, and slightly nutty undertones.
Questions
Sourdough relies on a live culture of wild yeasts and lactic acid bacteria to leaven the dough over roughly 24 hours, instead of the 2-hour process used with commercial yeast. This slow microbial transformation is what develops its flavour and health benefits.
The long fermentation process breaks down complex gluten protein chains and produces phytase, an enzyme that dismantles phytic acid, making minerals like iron and zinc more bioavailable. Many people with gluten sensitivity find sourdough easier to digest than yeasted bread.
Yes — sourdough bread produces a lower blood sugar spike compared to bread made with commercial yeast, making it gentler on your metabolism.
