Whole-Wheat Bread Triticum aestivum
Stale is a feature. Day-old is the only bread worth using for croutons or panzanella.
In the kitchen
Under heat
Toasting drives off surface moisture and browns the crust through the same reaction that browns a seared steak, just at a lower temperature.
Against air
Exposed bread stales as the starch recrystallizes, not primarily from drying out — which is why bread in a sealed bag can still go stale.
In storage
Room temperature in a bag for a few days, then the freezer — the fridge actually speeds up staling.
At the shop
Check the ingredient list, not the color. Brown bread can be dyed; "whole wheat" as the first ingredient is the only real signal.
Beyond the kitchen
BRAN CUTS THE GLUTEN
Wholemeal flour contains sharp bran particles that physically sever gluten strands as the dough develops, which is why wholemeal loaves rise less and come out denser. Longer resting and wetter dough compensate; more kneading does not.
THE CHORLEYWOOD PROCESS
Developed in Britain in 1961, this method uses intense mechanical mixing and additives to make a loaf in about three and a half hours instead of overnight. It produces the great majority of British bread and is the reason supermarket sliced bread tastes and keeps the way it does.
BREAD AND POLITICS
Bread price has triggered political upheaval repeatedly: the French Revolution's bread riots, the Roman grain dole, Egypt's 1977 bread riots, and wheat price spikes preceding the Arab Spring. Few commodities have so direct a line between supply and unrest.
THE SOURDOUGH STARTER
A starter is a stable culture of wild yeasts and lactobacilli that will keep indefinitely if fed. Commercial bakeries maintain starters passed down for decades, and some claimed lineages run to well over a century.
A longer history
Wheat was domesticated in the Fertile Crescent around ten thousand years ago and is one of the founding crops of settled agriculture. Leavened bread is attested in Egypt from at least the third millennium BCE, and Egyptian bakeries were sophisticated operations — bread and beer were both staples and both were forms of payment.
For most of history all bread was wholemeal by default, because removing the bran required laborious sifting. White bread was therefore a marker of wealth for thousands of years, and the social order of a table could be read from the colour of its loaf. Roller milling in the late nineteenth century inverted this completely: white flour became cheap and universal, and wholemeal became the deliberate, more expensive choice.
Industrial baking in the twentieth century, and the Chorleywood process in particular, transformed bread from a daily craft product into a commodity. The artisan and sourdough revival since the 1990s is a reaction to that, and has made long fermentation and wholegrain milling commercially viable again for the first time in a century.
