Why We Make Unhomogenised Milk
Share with friends
Rebecca’s dad was the first person to say it out loud. A cattle farmer in Cheshire, he had spent a lifetime around livestock and could tell good work from bad on instinct. British retail milk, he reckoned, had drifted from what a good dairy cow can produce. There was room for someone to do it properly.
He said as much to Rebecca and Shaun, who at the time were living in London, thinking about what they might make together. Her father had seen more farms than they had. He was telling them something they were unlikely to arrive at on their own. You should do milk.
A coffee lens on a milk problem
Shaun came at the idea from the other side. He had moved to London at nineteen to work in coffee, spent time behind the bar at Kaffeine, won the English Aeropress Championship, and eventually set up a cart of his own, Noble Espresso. Speciality coffee has spent twenty years making one argument, over and over. That the small decisions are the whole game. That a bean grown in the wrong conditions, picked at the wrong time, processed on the wrong day or roasted too dark will never taste as good as one treated with care at every step. The best cups are not an accident, and neither are the worst. When he looked at milk through that lens, Rebecca’s dad’s observation started to make sense.
"A coffee is only as good as its weakest ingredient, and the milk was usually the weakest."
Homogenisation is a choice
Most of the answer is pasteurisation. Gentle heat, for safety. But most large dairies then do a second thing, quieter and less discussed. They run the milk through a machine that pushes it through pinpoint nozzles at pressure, to break up the fat globules until they are too small to rise. This is Homogenisation. It was invented, in the early twentieth century, to solve a retail problem. Supermarket customers did not want to see cream at the top of a bottle that might not be theirs yet.
Initially, we did not want to solve that problem. We wanted to solve a different one. Speciality coffee had spent twenty years raising the ceiling on what a coffee could taste like. Beans sourced with real care, roasted with precision, pulled on machines built for millimetre control. The milk being steamed into most of those cups had not kept up. A coffee is only as good as its weakest ingredient, and the milk was usually the weakest.
That was the gap we wanted to close. A milk that could hold its own against the coffee it was going into.
What unhomogenised milk tastes like
What you taste instead is the point. There is a roundness to unhomogenised milk that homogenised milk cannot replicate. A weight on the tongue. The fat sits differently, wrapped in the delicate
membrane the cow’s body built around it. Break that membrane and the compounds inside the fat leach out into the rest of the milk. Everything gets pre-mixed. You taste a blur of the whole thing at once. Leave it alone and you taste every element.
There is another thing too. Our milk moves through the year. In spring, when the cows come off winter feed and back onto fresh pasture, the cream line deepens and turns a richer gold. In high summer it is almost sweet. In winter it is paler and restrained, you can taste where you are in the calendar.
The membrane the cow built
None of this is a romantic argument, or not only one. The fat globule membrane that homogenisation destroys is a real biological structure. The cow’s body builds it, carefully, to hold the fat in suspension and to deliver it whole. There is research underway into what that membrane does in the human body too, how it carries certain lipids, how it behaves in digestion. The science is still developing, and we are careful not to overstate it. But the underlying principle feels sound enough. If an animal has spent its biology assembling something with intention, the default assumption should probably be to leave it intact.
"The cream line is a signature. Proof the milk is behaving the way real milk behaves."
It lets the quality of the milk show
There is a more practical reason too. When milk from hundreds of farms is pooled and blended before bottling, a uniform bottle is the only honest one you can sell. Our milk does not work that way. It comes from a smaller, known herd, on pastures we know, and we do not want to hide any of that. The cream line is a signature. It is proof that the milk is behaving the way real milk behaves, from cows doing what cows should be doing. If we homogenised it we would be erasing the evidence of the farmers work.
Left alone
That is really all we have been trying to do. Take what Rebecca’s dad pointed at, and put it in a bottle. A milk that looks the way milk is supposed to look, from a herd that is doing what cattle are supposed to do. Nothing done to it that does not need doing.
Frequently asked questions
Is unhomogenised milk better for you than homogenised?
It is less processed, which is the clearest answer. Research into the milk fat globule membrane and digestion is ongoing and promising, but we are careful not to overstate it. What we can say confidently is that our milk is closer to its natural state, and that the ingredients have not been altered for cosmetic reasons.
Does unhomogenised milk keep as long?
Yes, provided it is pasteurised (ours is). Homogenisation has no meaningful impact on shelf life. Keep it cold, keep it upright, use by the date on the bottle.
Why does the cream rise to the top?
Fat is less dense than water. Left undisturbed, fat globules gradually float. In homogenised milk they have been broken small enough to stay suspended. In ours, they are whole, so they rise.
This is the cream line, the visual signature of unhomogenised milk. Some people also call it cream-top milk, for exactly that reason.
Is unhomogenised milk the same as raw milk?
No. Raw milk is unpasteurised.
Unhomogenised milk can be pasteurised or raw. Ours is gently pasteurised but left unhomogenised so the cream structure stays intact. The two words describe different things.
How do I use unhomogenised milk in coffee?
Skim the top layer for cappuccinos if you want extra body, or shake the bottle and use the whole milk for flat whites and lattes. The natural fat structure steams to a silkier microfoam than homogenised milk tends to.
