Sourdough or sourfaux?Does it go against the grain if your bread is fake?" width="976" height="549">
It is hailed as a bread that lasts longer, is easier to digest and has a unique tangy taste.But apparently sourdough can vary hugely depending on where you buy it.According to an investigation by Which
What is traditional sourdough?
Traditional sourdough is considered to be one of the oldest forms of bread and the technique can be traced back to ancient Egypt.
It is made from just three ingredients: flour, water and salt. The dough begins with a "starter culture" - also made with flour and water - which is left to bubble up for several days. It is this which makes the bread rise, instead of adding yeast.
A sourdough starter culture takes days to develop before being mixed with flour, water and salt to create the dough
"It's bread in its purest form," says Anna Herbert, from family business Hobbs House Bakery, in Chipping Sodbury, Gloucestershire."A true sourdough should not have yeast in it because the starter sourdough itself rises it."
What about "sourfaux"?
According to a report by the British Baker magazine earlier this year, sourdough is truly an in-demand product with supermarket sales up by 98% in the past year. And it is trendy too, with more than 1.5m Instagram posts tagged with #sourdough.

Pumpkin pie sourdough boule with pumpkin pie spice from @savoryspiceshop it smells like a fresh pumpkin pie and it tastes like one too! This is my second attempt at this brain child and the first one didn’t have enough pumpkin flavor (upped it from 10% to 20%), so this is the new and much improved remake! Sweetened with brown sugar and a little bit of golden syrup I had left over from a sticky toffee pudding.? . . . . #sourdough #sourdoughbread #artisan #artisanbread #foodie #fallfood #naturallyleavened #naturalyeast #naturallevain #wildyeast #wildyeastbread #breadscoring #masamadre #painaulevain A post shared by Tobin (@the_bread_babe) on Sep 30, 2018 at 4:04pm PDT

But Which? magazine says it looked at 19 sourdough loaves sold in supermarkets and found only four were made in the traditional way with the three basic ingredients.The others contained extra ingredients, such as yeast, ascorbic acid and yoghurt and vinegar.While these are not necessarily bad for you or unhealthy, Chris Young from the Real Bread Campaign says customers are being misled."If you are told you are buying something, you should get what you pay for. Particularly when some of the supermarkets are charging a premium for that product," he said.The Real Bread Campaign group says it wants to see a legal definition of the terms "sourdough" or "artisan bread", so stores cannot "misinterpret" them.
Is there a difference?
The Real Bread Campaign has called for more research to be done on the benefits of sourdough, but cites some studies which suggests it is more digestible and nutritious than the mass-market loaves of bread found in the bakery aisles.It says the naturally-occurring yeast in sourdough is less concentrated than in commercial baker's yeast and so may be better for people who react badly to excessive yeast in bread.The campaign also cited several studies showing how the glycaemic index of sourdough is lower than other breads, meaning it does not cause spikes in blood sugar.

Vanessa Kimbell, a sourdough expert specialising in the digestion and nutrition of bread, says fake sourdough is "very difficult in terms of irritable bowel syndrome and diabetes"."It's absolutely scandalous," she said. "Many diabetics are eating sourdough to control blood sugar levels. Eating fake sourdough can spike sugar levels."

Ms Kimbell adds: "I believe manufacturers have a responsibility to define if the sourdough refers to the process or if it's the flavour."Tell people if it's the flavour."It is clear that supermarket loaves with the sourdough flavour are hugely popular - despite deviating from the traditional recipe.Tesco says it sells around 100,000 sourdough loaves a week and has quadrupled its sourdough range in the last five years.But if you do want your sourdough loaf to be authentic, the Real Bread Campaign has a clear message: always read the label or ask someone in-store.
