The milk in that bottle has, at times, been sold cheaper than the water beside it on the shelf, and the man who produced it has been paid less than it cost him to make.
Look at the actual pennies, because that is where the cruelty hides.
It costs a typical British dairy farmer somewhere around 44 pence to produce a litre of milk. Feed, energy, vet bills, labour, the cows milked twice a day, every day of the year, Christmas included. That is the floor he has to clear just to stand still.
Now the price he is handed for that litre. In early 2025 it sat in the mid forties, which leaves a margin of a penny or two on each litre for one of the hardest jobs there is. Then through late 2025 the processors cut, and cut again, dragging the farmgate price down into the mid thirties, with some farmers paid under thirty pence. By the spring of 2026 the UK average had fallen to around 34 pence.
Do that sum. Around 44 pence to make it. Around 34 pence paid for it. The farmer is losing something like ten pence on every single litre his cows produce, and a dairy cow does not stop producing because the price went wrong.
He cannot pass that on. A handful of giant processors and supermarkets sit across the table from thousands of small farmers, and they set the number. He takes it, or he pours good milk down the drain.
The meeting did not go badly for everyone, mind. In the very stretch that farmers were being paid below the cost of production, the big processors were posting record results, hundreds of millions in profit, ploughing hundreds of millions more into new plant and capacity. The squeeze simply moved up the chain, out of the cold parlour and into the warm boardroom, where it turned into a bonus.
So the farmers leave. There are now only around seven thousand dairy farms left in the whole of Great Britain, down from many tens of thousands a generation ago. The small family herds went first. The milk comes from fewer and bigger units every year, and the patchwork of family dairies that once covered this country is wearing through to nothing.
The shopper sees cheap milk and feels lucky. The cheapness is a quiet transfer, out of a farmer's livelihood and into the appearance of a bargain, paid for in ten pence pieces by a man in a cold parlour at half past five in the morning, working out how many more months he can afford to feed you.
