Real Sourdough meeting with DEFRA update 2023 There is now a code of Practice

10 October 2015 by Dr Vanessa Kimbell
Meeting at DEFRA
Meeting at DEFRA Ben from Sustain, George Eustice, Vanessa Kimbell, MP Chris Heaton Harris.

You may remember a long time ago on 2015 I instigated a meeting with DEFRA through my MP and neighbour Chris Heaton Harris. I baked bread, and was able to speak at length to George Eustice, and I invited Sustain to attend the meeting.

Below is the post I wrote, word for word, but I adding an update.

Almost 8 years later and I am delighted that Sustain and The Real Bread Campaign were able to see this through as the news is that The Association of Bakery Ingredient Manufacturers (ABIM) has now published the first-ever code of practice for sourdough. The document outlining clear and concise definitions for sourdough published on the 31 January 2023 sets out suggested definitions for correct labelling and marketing of sourdough bread products – which “must not mislead the consumer as to the true nature of the product.”

I am delighted.

The details of the original visit to DEFRA over Sourdough labelling published October 2015.

Not all sourdough as equal. I’m often asked about why some people can digest some sourdough and not others.  The shocking truth is that there is fake sourdough on sale all over the UK.

Sourdough is coming to the forefront of bread production. It is the buzz word in the bread industry right now as sales of mass-produced bread have been falling for several years.  There is a huge interest in developing sourdough as most manufactures realise that to go forward they need to look back. There is a very real situation as the use of sourdough, the name and the benefits of long slow fermented bread been hijacked by the corporates. There are several large corporates who are producing mixes that allow mass production of fake loaves, and numbers are ever-increasing.

Last year I was handed a packet of instant sourdough flavour from one of the Directors of the largest yeast manufactures. Just add this to your normal dough and hey presto – instant sourdough. I was horrified. He, on the other hand, seemed amused by my convictions that sourdough should be made traditionally.  My convictions that sourdough should be made using just flour, water, salt and a live starter and not mass manufactured with additives is right at the foundation of what I believe in. My fear is that one day artisan bakers won’t be selling sourdough, that additive-laden, biologically inactive sourdough will become the norm   … and bakers will have to justify their product and sell ” real sourdough.”

Producing an acidified fake flavoured loaf is confusing to consumers who are turning to sourdough to support their physical and mental health

Given that I teach the mechanisms of how sourdough facilitates easier digestion, lower symptoms of IBS and more regulated blood sugar and I felt that the manufacturing of sourdough needed protecting – now. I complained to the food standards agency. They replied that they could not help as there is no legal definition of Sourdough so in January last year I approached my MP Chris Heaton Harris .

I explained that the lack of a designation means that large corporates are able to manufacture and sell fake loaves with total impunity. The mass manufacturers even use terms that steal the efforts of real artisan bakers. I explained that real bread bakers are not able to compete on a level playing field and that consumers are being sold sourdough that does not have any of the unique properties of true sourdough bread.  Two of which as the improved digestibility and the manageability of blood sugar levels. I backed up these facts with studies.  Chris  Heaton Harris was brilliant and then asked in the early summer if I could meet with several MP’s in Parliament. I asked the #realbread campaign to come to this meeting and we made a solid case that my MP took to DEFRA.

So I have opened the door to a government consultation.

In October last year I travelled back to London again, but this time to DEFRA and I met with my MP Chris Heaton Harris, Ben from Sustain, and George Eustace the Minister of State at the Department for Environment, Food and Rural Affairs (DEFRA) and with the civil servants in charge of bread legislation.  It became clear as we talked that this was not just about integrity and health, but in real terms the economic burden of illness from poor quality bread needs addressing by DEFRA and the relationships between the agricultural industry, the four regulations and bread production need addressing and reviewing.  Protecting sourdough and the impact of improved heath would a be significant boost to the economy; I literally worked on the % of working days lost from IBS alone in the UK as an example of the potential of sourdough to improve GDP if regulated, on the population.

The meeting was supposed to be 20 minutes and I am delighted to say that the meeting ended up being almost and hour and half. I successfully managed to get the points across and George he agreed to look further in to this and consider a designation for Sourdough. I’m delighted to say that we are meeting with DEFRA  this month to discuss more specifics later this month.

It is not an easy task to produce a definition of sourdough that protects both the consumer and the artisan baker.  The French though, have defined their Pain de Levain  in their Decree n° 93-1074 of 13 September 1993 made for the application of the law of 1 August 1905 with regard to certain categories of bread, and included sourdough as follows.

Article 3 — Breads sold under the category of “pain au levain” must be made from a starter as defined by Article 4, just have a potential maximum pH of 4.3 and an acidity of at least 900 parts per million

Article 4 — Starter is a paste made from wheat or rye, or just one of these, with safe water added and salt (optional), and which undergoes a naturally acidifying fermentation, whose purpose is to ensure that the dough will rise. The starter contains acidifying microphone-flora made up primarily of lactic bacteria and yeasts. Adding bread yeast (Saccharomyces cerevisiae) is allowed when the dough reaches its last phase of kneading, to a maximum amount of .2 percent relative to the weight of flour used up to this point.

The starter can be dehydrated provided that the dehydrated starter contains one billion live bacteria and one to 10 million yeasts per gram. After rehydration and possibly, addition of bread yeast (Saccharomyces cerevisiae) under the conditions envisaged with the preceding subparagraph, it must be able to ensure a correct lifting of the dough. The starter can have micro-organisms added to it, authorized by decree of the Minister for Agriculture and the Minister in charge of Consumers, made upon the advice of the commission of food technology created by the decree n° 89-530 of 28 July 1989.

    Same problem here in The Netherlands Vanessa, bakeries selling ” so – called “sourdough bread as the healthy option when actually it is bread made with sourdough powder. They say it takes to long to make real sourdough bread and it would not be efficient in labour costs (2 to 3 days takes too long).

    Well done for taking up this fight, Vanessa. I agree that sourdough needs to be protcted. I would like to see a definition that excludes added yeasts and uses only naturally yeasts from the environment. Part of the reason sourdough suits our digestion is that it contains local flora. Added yeasts could come from anywhere. If sourdough gets protected in UK hopefully other countries will follow suit.

    A great initiative on your part, Vanessa. Congratualtions and best wishes for your success with this campaign. ‘Artisan baker’ is a term that should also have been protected, but that battle has clearly already been lost.

    We must protect sourdough. Without people who care, and who have the skills to produce the genuine article we will have no real food left. The disregard man has for the connection between real food and health is astounding, particularly if a profit can be made.

    Well done on taking up such an important issue!

    As regards the definition, I think the most important thing is that Sourdough should not contain any added yeast (bread or otherwise). I eat sourdough as I am allergic to yeast (as are 3 other members of my extended family) and so knowing that it really is true sourdough is so important. I’m already fed up of having to ask to find out if what is being sold as Sourdough really is what it’s called!

    Hello Vanessa, this is the first of your emails that I have received having only just joined your group – and the irony of it is that I have just watched the Victorian Bakers programme on TV with its adulteration and fakery. I fully support your campaign being a sourdough home baker myself having been taught by Vicky Harford- a professional baker down here in Cornwall.

    It seems to me the French approach looks a reasonable one to adopt too and no doubt will be a source of strength to your campaign.

    Best regards,

    Bruce G.

THE SOURDOUGH SCHOOL – HAND CARVED WOODEN LAME THE SOURDOUGH SCHOOL – HAND CARVED WOODEN LAME

One of the biggest issues around using a plastic lame to score sourdough, of course, is that eventually the blade will become blunt and the lame could end up in landfill.  So several years ago I talked to my dear friend EJ about developing a lame with a replaceable blade. And he came up with this very beautiful hand carved wooden lame.

Very sadly EJ is no longer with us. Recently a friend of EJ’s who is also a wood turner and carver offered to make these again for us in remembrance of our dear friend.

The Baking As Lifestyle Medicine (BALM) Protocol The Baking As Lifestyle Medicine (BALM) Protocol

The current food system is broken at multiple levels, from the pesticides used in our soils to the emulsifiers and additives adulterating industrially-processed foods. Nowhere is this more apparent than in the bread we eat.  The figures reported by the UK Flour Millers say that bread is bought by a staggering “99.8% of British households” and that “the equivalent of nearly 11 million loaves are sold each day. Approximately 60-70% of the bread we eat is white and sandwiches are thought to account for 50% of overall bread consumption. Average bread purchases are the equivalent of 60.3 loaves per person per year.” 

Most bread sold is made by modern processing methods that strip heart-healthy whole grains of their nutrient contents, resulting in low-fibre bread with a high glycemic index. Over time, white processed bread can increase a person’s risk of insulin resistance alongside other lifestyle diseases.

We’re on a mission to revolutionise the bread making process at every level – from soil to slice. The rules governing this are laid out in our Baking As Lifestyle Medicine protocol.
