The oat milk most people assume they're drinking, and almost never are.
London Coffee Festival is on Brick Lane this week. Twenty-two thousand people, four days, the best baristas in the world pulling shots in real time.
Every cup on the LCF stage will start with fresh espresso. Most of those same cups will be finished with milk that's been sitting in a carton since spring.
Three things that follow from that. How it tastes. How it pours. And how you actually get fresh oat milk delivered to a kitchen in Tobermory on a Tuesday.
Taste. Fresh coffee deserves fresh-made milk.
Coffee culture has a small inconsistency that nobody talks about.
We grind beans the second we want to brew them. We dial in the espresso. We watch the extraction, time the pour, fuss over the crema. Then we top it with milk that's been sitting in a carton since spring.
If a barista handed you a coffee made with beans roasted six months ago, you'd send it back. Nobody sends back the milk.
“Fresh coffee deserves fresh-made milk. Not something that has sat in a carton for weeks and needs dipotassium phosphate to hold itself together.”
What's actually in a carton of barista oat?
Pull a carton off the shelf and turn it round. Most of the back label is fine. Then you'll see things you didn't ask for.
Dipotassium phosphate. Acidity regulators. Sometimes lecithin. Sometimes a quiet little “added sugar”.
None of these belong in oat milk. They're in there because the carton has to survive a journey the oats can't survive on their own. Months in a warehouse, weeks on a lorry, a few more weeks on a shelf. Without help, the proteins start to fall apart and the foam gives up the moment it meets a hot espresso.
Dipotassium phosphate is the clearest tell. It's the chemical that stops oat proteins curdling in coffee. Take it away and most carton oat milks split in the cup. Leave it in and they hold long enough to be poured. That trade is invisible to whoever's drinking it. But it's the cost of putting oat milk in a carton.
What we did instead
We took the water out.
A MYOM Barista pouch is a small concentrated blend. Drop it into a glass bottle, top up with cold water, shake. A litre of fresh barista oat drink in about thirty seconds. The milk going into your coffee was made closer to now than the beans were ground.
Because we make it fresh, the ingredient list gets short. Oats. Cold-pressed rapeseed oil. A little salt. Water. Fortification: calcium, vitamin D3 from lichen, vitamin B12, iodine. Fava bean protein in the Barista blend, for the foam.
No dipotassium phosphate. No gums. No emulsifiers. No added sugar. The oat drink most people assume they're already drinking, and almost never are.
Performance. Built for the bench.
Pouch. Bottle. Water. Shake.
Anyone who has watched a bartender make a cocktail recognises the rhythm. Twenty seconds of motion, two hands, ice rattling off the inside of the tin, and something better than the sum of its parts arrives. We borrowed it.
A MYOM Barista pouch goes into a glass bottle. Cold water tops it up. Cap on. Shake for twenty seconds. By the time you've reached for the portafilter, there's a fresh litre of barista oat drink on the counter, ready for the steam wand.
No carton waiting in the fridge for three weeks. No flat morning pour because the milk's been sitting since the bank holiday. Every time you make it, it's the first pour of the day.
What baristas need from a barista oat
Talk to anyone running a busy café and they'll describe the same four things. The milk has to:
- Foam glossy and fine, so the latte art lays cleanly across the surface and the flat white has that silky pull on the lip.
- Hold its nerve at 60 to 65 degrees, where oat foam wants to behave. A degree past that and it splits, and you're starting again.
- Pour the same on the fifteenth cup as it did on the first. Because the fifteenth customer paid the same money.
- Carry the espresso, not flatten it. The cup is about the coffee. The milk supports it, the way a good sauce supports a steak.
Carton barista oats meet most of these most of the time, with help from dipotassium phosphate and friends.
MYOM Barista meets them without the supporting cast. Fava bean protein for the structure. A touch of cold-pressed rapeseed oil for the elasticity. Made fresh in the past minute. That's the whole formulation, and it's the whole performance.
The home barista's edge
If you're pouring at home, here's the part that should make you smile. The fifteenth-cup-of-the-morning problem isn't yours. You're making one flat white. Maybe two. With MYOM Barista, you're starting that pour with milk that was a pouch, water and a bottle thirty seconds ago. Café-grade, fresher than anything a café could realistically buy in.
That's not a marketing line. That's just the maths of how it gets there.
Barista-grade isn't a label. It's a behaviour. And on a good morning, in a quiet kitchen, you're delivering it.
Access. Wherever you actually live.
London Coffee Festival is wonderful. It is also in E1.
Most of UK coffee culture happens somewhere else. A flat in Manchester. A kitchen above a pub in Edinburgh. A surf shack in Cornwall. A camper van outside Tobermory. The Glasgow flat white drinker watching Coffee Masters on a phone propped against the kettle. None of them are at Brick Lane this weekend. All of them want a decent flat white on Saturday morning.
MYOM Barista is delivered direct to your door. No store visit required. It lives in your cupboard, not your fridge, until you open it. Order on Wednesday and you'll have it by Saturday, anywhere with a UK postcode. There's no London Edition, no specialty stockist near you to chase, no carton to bring back from the city. Just a small black pouch, a glass bottle, and twenty seconds with the cap on.
The pouch on Brick Lane and the pouch on the Pembrokeshire coast come from the same line. Made fresh by you, in the same thirty seconds, in whichever kitchen you happen to be standing in.
How to pour it. The barista standard, executed.
With the right product on the bench, the technique is straightforward. Six steps. Each one matters.
1. Start cold. Below 6 degrees Celsius.
Pour MYOM Barista straight from the fridge. Colder milk absorbs air more gradually, which creates smaller bubbles and a finer microfoam. If the milk is warm when you start, the window to stretch and polish the foam closes too quickly.
2. Fill the jug halfway.
Use a stainless steel jug with a proper spout. Fill to just below the bottom of the spout. Milk expands when you steam it, so halfway gives you room to grow.
3. Stretch in the first three to five seconds.
Position the steam wand tip just under the surface. You should hear a gentle hiss, not a harsh tearing sound. This is the stretch phase. Add about 20% volume in the first three to five seconds, then stop introducing air.
4. Whirlpool for the gloss.
Drop the wand tip slightly deeper and angle it to set the milk spinning. The whirlpool breaks large bubbles into small ones. This is where the gloss and the silky texture come from. Keep it rolling until the jug is warm to the touch but not hot.
5. Stop between 60 and 65 degrees Celsius.
Around 60 to 65 degrees is the sweet spot for oat drink. Hotter than that and the oat flavour flattens, the proteins start to destabilise, and the foam separates from the liquid. A thermometer helps at first. Your palm on the side of the jug learns quickly.
6. Tap, swirl, pour from height.
Knock the jug on the counter twice to burst any stray large bubbles. Swirl the jug to polish the foam into a glossy, paint-like texture. For latte art, start pouring from height to push through the crema, then drop close to the surface to lay the pattern as you finish.
Five drinks to pour during LCF week
Whether you're inside the festival or watching from your kitchen, here's what to pour over the four days.
- Flat white. 60ml double ristretto, 120ml MYOM Barista steamed to 60 degrees, 3 to 5mm of glossy microfoam. The Saturday morning benchmark.
- Iced oat latte. Double espresso over ice, cold MYOM Barista poured straight from the bottle. Cleaner than most iced lattes, because of the protein. The drink for when the Brick Lane queue turns sweaty.
- Cortado. Equal parts espresso and warm MYOM Barista at around 55 degrees. Foam minimal, balance everything. Sunday afternoon, while the Coffee Masters final plays out somewhere in the background.
- Dirty chai. Espresso into a hot chai latte made with MYOM Barista. The natural sweetness of the oat lifts the spice. Friday night, debrief over the week.
- Cold foam iced latte. Whip cold MYOM Barista with a handheld frother for 30 seconds until it doubles. Spoon over an iced long black. Café standard, two minutes flat.

Frequently asked questions
Why does fresh-made matter for oat milk performance?
Fresh-made oat milk foams better than carton oat milk because the proteins and starches that build microfoam haven't had time to break down. Carton barista oats are heat-treated and stored for months before they reach a steam wand. MYOM Barista is made from a concentrated pouch in about 30 seconds, so the proteins are intact and the foam holds together cleanly for latte art.
What is dipotassium phosphate and why does carton barista oat use it?
Dipotassium phosphate is the chemical that stops oat proteins curdling when the milk hits hot espresso. Without it, most carton barista oats split in the cup. It's there because the carton has to survive months in storage before it reaches you. MYOM Barista doesn't need it. We make the oat drink fresh from a pouch when you want it, so the proteins are still intact when they hit the steam wand.
What does barista-grade oat milk actually mean?
Barista-grade is shorthand for an oat milk that does four things on the bench. It builds fine, glossy microfoam. It holds its nerve between 60 and 65 degrees without splitting. It pours the same on the fifteenth cup as it does on the first. And it carries the espresso instead of flattening it. MYOM Barista does all four, made fresh from a concentrated pouch the moment you shake.
Can I get MYOM Barista delivered outside London?
Yes. MYOM Barista posts to any UK postcode in 1 to 3 days. The box lives in your cupboard until you open it. Whether you're in central London, the Highlands, Cornwall, Belfast or anywhere in between, you order the same product and pour fresh, café-grade oat milk the same day it arrives.
How is MYOM Barista different from Oatly Barista?
MYOM Barista is a concentrated pouch you mix with water at home to make a fresh litre of oat drink in around 30 seconds. The ingredient list is short: oats, rapeseed oil, fava bean protein, salt, water and the standard fortification. No dipotassium phosphate, no gums, no added sugar. Oatly Barista is a 1L carton that has been pasteurised, stored for months and shipped through a longer route, with dipotassium phosphate and oil in the recipe to keep the foam stable through that journey. The MYOM pouch also weighs roughly a sixth of what a carton weighs, and posts through a letterbox.
What temperature should I steam MYOM Barista to?
Steam MYOM Barista to between 60 and 65 degrees Celsius. Above 65 degrees the oat flavour flattens, the proteins start to destabilise and the foam separates. MYOM Barista holds its structure reliably in this range because the foam is built on fava bean protein and oat starches, not on synthetic stabilisers.
Can I use MYOM Barista without a steam wand?
Yes. A handheld milk frother or an automatic frothing jug both work well with MYOM Barista. Start with the milk fully chilled below 6 degrees Celsius, run the frother for 20 to 30 seconds until the volume doubles, then tap and swirl the jug. The foam will not match a proper steam wand result, but it holds long enough for a flat white, latte or cortado.
How do I use the MYOMXLCF26 discount code?
Add the MYOM 1L Barista Oat Everyday Bundle to your basket at myom.shop, then enter MYOMXLCF26 at checkout. You will save £8, bringing the bundle price to £10.99. The offer is valid until 31 May 2026.
Fresh coffee, fresh-made milk. Pour something better this week.
LCF will be brilliant, as it always is. The Coffee Masters will pull shots that go on TikTok by Sunday night. Latte Art Live will produce pours nobody at home is going to copy first try. The Demo Bar will show off machines that cost more than rent.
Watch all of it. Take notes. Copy what you can.
And when it's over, when the lanyards come off and the kettle goes back on at home, you'll pour your espresso into something. Make it something fresh.
