Choice of ingredients for a quality sourdough

The fundamentals of Natural Sourdough

THE Natural leaven consists mainly of flour and water, but the quality of these components can significantly influence the growth and activity of the culture of microorganisms present. The ingredients chosen to feed the sourdough must promote optimal development of naturally present yeasts and lactic acid bacteria.

Flour quality

The selection of the flour is crucial for a quality sourdough. Wholemeal or semi-wholemeal flours, rich in nutrients and enzymes, are preferable because they provide a rich and varied diet for microorganisms. The presence of germs and bran particles in these flours also stimulates fermentation activity, essential to the good health of the leaven.

It is also essential to consider the origin and type of cereal. Flours made from organic wheat or rye guarantee the absence of pesticides and other chemicals that could disrupt fermentation.

The importance of water

L’water, a vital element of sourdough, must be purified or lightly mineralized so as not to introduce contaminating agents which could inhibit the development of cultures. Chlorinated water, for example, can destroy beneficial yeast and bacteria in sourdough. It is therefore advisable to use filtered or spring water.

Frequency and proportions of refreshment

The regularity of refreshed is a fundamental aspect in the management of sourdough. Regular feeding (every 24 to 48 hours) and constant proportions are recommended to maintain balanced fermentation activity. As a general rule, the ideal proportion per refreshment is 1:1:1 (sourdough: water: flour).
