Say not to sourfaux

Research by The Real Bread Campaign has discovered packet mixes marketed as sourdough that contain up to 22 ingredients and artificial additives.

As Britain’s apparent love of sourdough is growing, the Real Bread Campaign believes that some manufacturers and retailers may be taking advantage of our desire.

The only ingredients necessary to make genuine sourdough are flour, water and salt. One supermarket’s ‘Sour Dough [sic.] Bread Mix’ lists more than twenty ingredients and artificial additives, including an unspecified added flavouring. Meanwhile, the sixteen listed on another company’s so-called ‘simple sourdough’ mix include mono- and diacetyl tartaric acid esters of mono- and diglycerides of fatty acids.  A third packet mix contains added yeast.

Real Bread Campaign coordinator Chris Young said “Britain’s shoppers deserve better than to be sold the promise of a shortcut that turns out to be an expensive way of making an additive-laden loaf without the benefits genuine sourdough offers. Surely it says something when a manufacturer feels the need to add flavouring.”

What is genuine sourdough?

By definition, the only ingredients necessary to make genuine sourdough are flour and water. From this a baker will nurture the yeasts and lactic acid bacteria that occur naturally on cereals, and therefore in the flour, to make a live starter culture. A pinch of salt is a useful addition and some bakers might include other natural ingredients for variety.

Over the longer fermentation time needed by ‘wild’ yeasts to work their magic, the bacteria bring about changes in the dough that improve the texture and flavour of the finished Real Bread. A growing number of studies suggest the natural processes could have nutritional and other health benefits to boot. These cannot happen in loaves made without a live starter culture or accelerated by commercial yeast.

To protect shoppers looking to buy (and local, independent Real Bread bakeries that make) the genuine article, the Campaign calls for a legal definition of the word sourdough as part of an Honest Crust Act.


In the meantime, the Campaign calls on people to say no to #sourfaux, which is what the Campaign calls any product marketed as sourdough that is in fact made using any of the following:  

  • commercial yeast
  • inert, dried sourdough powder
  • sourdough concentrate
  • yoghurt, vinegar, or other non-sourdough acidifier
  • flavourings, preservatives, processing aids and other artificial additives

This month is #SourdoughSeptember. Rather than giving any #sourfaux manufacturers free publicity by naming and shaming, the Campaign is choosing to encourage people to learn to make their own sourdough from flour, water and salt, or seek out small, local, independent Real Bread bakeries that can guarantee the genuine article.

The Campaign wrote to the customer services departments of the three companies marketing the packet mixes as ‘sourdough’, urging them to rename or withdraw the products. All three declined to do so.
