1770 – Recreating a Heritage grain beer barm bread

30 April 2011 by Dr Vanessa Kimbell
1860 - miller & brewer - uk - 3-680

Heritage grain

I’ve been researching the history of bread. We’ve been eating long slow fermented bread for thousands of years, but in the past century we have adulterated bread beyond all recognition.  There are more and more people reporting digestive difficulties associated  wheat, made into bread in with industrialised processes that take little more than an hour or so from start to finish; yet many of these same people seem to be able to eat long slow fermented bread. So I have been investigating how we used to make bread. What I discovered was that wild yeast wasn’t the only leaven used in bread.  For hundreds of years beer barm was used, with a long slow fermentation.

When the opportunity to buy this first edition rare pamphlet, with the main text going into considerable detail of using beer barm in the making of bread I just couldn’t resist it. According to the rare book dealer who sold it to me there are only 5 copies only on the ESTC which have a copy, which are The British Library, John Rylands, St. Andrews University, University of Chicago and Yale.

The full and glorious title of this text lightly browned, stitched pamphlet is The Complete Baker; or a Method of effectually raising a Bushel of Flour, with a Tea-Spoonful of Barm: Intended to obviate the great Difficulties Bakers are often put to, for want of a Quantity of Barm, that very necessary Ingredient in making of Bread. In which is likewise shewn, that the Cause of Bread being close and heavy is entirely owing to the Baker being unacquainted with the Nature of Barm and Flour. By James Stone, of Amport, in Hampshire, and it was published by Salisbury: Printed for the Author; and sold by all Booksellers in Town and Country in 1770

To ensure the bread was as authentic as possible I used John Letts 18th century flour and Harts Family Brewers in Wellingborough kindly supplied the beer barm. It was fascinating to recreate a loaf of bread from almost 250 years ago, not least because I was worried about the unpredictability of the barm coupled with an unfamiliar flour blend … I had planned to write the recipe up, but I got really enthused … and so made a short video instead.

    I am currently working on baking using 18 the century recipies. Is the Heritage flour used the same or different? What product do you recommend for biscuits, cake and puddings?

    Curious Q.

    Where would I get the 18th Century Flour. ship in from the UK? Living in the USA makes that a small problem unless you have some recommendations. I doubt King Arthur Flour has any replica of what you are using.

    Cheers,

    What a beautiful video. The story of this bread is fascinating. I’d like to make it myself but am unsure of how much water and flour to use with the barm.

      Start with a teaspoon of barm. Add 100 ml of water with 100g of strong flour. Stir. From this scale up to the amount you need. It should be quite active and ready to double again within about 6 – 8 hours.

IBS AWARENESS MONTH Do you suffer from irritable IBS AWARENESS MONTH

Do you suffer from irritable bowel syndrome (IBS)? It can be tough to deal with the uncomfortable symptoms of stomach cramps, constipation, diarrhoea and bloating. But did you know that making dietary changes, such as incorporating sourdough bread into your diet, could help alleviate some of those symptoms?

Studies have shown that sourdough's long, slow fermentation process can reduce IBS symptoms. Plus, during #ibsawarenessmonth, we're exploring how adding different herbs and spices to your sourdough can further improve both the flavour and the digestion of your bread.

Let's talk about gut health, fermentation, and how sourdough can be a delicious and healthy addition to your diet. Join the conversation and share your experiences with IBS and sourdough.

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.
