Do you assume that cafés who use automated milk foamers are dishonest? Or that the selection to hurry issues up can also be a call to compromise on high quality? Effectively, this would possibly shock you, however each time you steam milk, you’re quietly including water to it. Swap to automation, and that water disappears. If you steam milk, steam condenses into the liquid, that condensate turns into a part of the drink, so the whole quantity will increase… By A LOT!! So which one is dishonest?
Go steam your self some milk. Weigh the milk at the beginning and weigh it once more after heating it to 55°C (the best serving temp for a latte). You’ll virtually definitely have gained ~7.5–10% in water weight.
Which means a latte with 200-mL milk might include:
And from a style and texture perspective, that’s not ideally suited. In reality within the WBC, the pattern has been getting in the other way. Notably current previous winners Jack Simpson and Anthony Douglas: two World Barista Champions doing all the things they will to focus their milk by way of strategies like cryodessication — to make it much less watery. So there’s a major benefit automation has over conventional milk steaming — while it doesn’t focus the milk, no less than it doesn’t water it down.
We’re writing a brand new on-line course and certification proper now known as The Café Administration Course, and we’ve been doing numerous interviews with actually good and skilled specialists in all facets of café administration. And we immediately realised that, by not diluting your milk with steam — as has been the usual apply for no less than 120 years of café tradition for the reason that first Ideale machines hit the bars replete with steam wands —, café homeowners are going to be paying fairly much more to make every milk-based beverage. These subsequent few tables will shock you.

Milk Dilution Ranges by way of Steaming
Let’s say your café’s latte is made with 200mL of milk. And we all know you’ve been getting between 7.5–10% dilution from steaming. And also you make 500 of those a day. Listed here are the numbers.
Value Influence (Australia)
How a lot does it value you if you happen to immediately miss out on the dilution issue? Right here’s an estimate on the way it works out if you happen to’re based mostly in Australia. After all, it depends upon what number of coffees you make and if you happen to use a budget and cheerful homogenised Holstein Friesian milk or the great natural homogenised milk, so we’ll work out a variety for you on milk prices. Right here’s a low, mid, and excessive milk worth per L so that you can ponder if you happen to’re not getting that 7.5-10% dilution degree you’re accustomed to:
Cleansing Chemical substances Value
Not like steam wands which could be simply wiped, rodded, unscrewed and purged with ~120°C steam which sterilises them, automated milk programs require chemical cleansing. That’s since you’re piping milk by means of a warmth trade system and plenty of ¼ inch pipes and it will get unhygienic until they’re cleaned on the each day. You’re really useful to make use of 50 mL/day of the liquid cleaning soap they make for this goal and it prices painfully greater than you’ll anticipate. Right here’s a Cleansing Value desk to contemplate:
Electrical energy Prices
There’s one closing value to contemplate and that’s the electrical energy value on working an additional equipment. Right here’s our estimate on what it prices to warmth the milk in query. These numbers are based mostly on 500 lattes a day. On paper, a unit just like the Übermilk is a 3.0–3.1 kW machine, however that’s its most draw, not its fixed consumption. For a café serving 500 milk drinks per day, heating roughly 100 litres of milk from fridge temperature to serving temperature would require about 6 kWh/day at minimal, which interprets to roughly A$730–A$860 per 12 months at present Victorian small-business electrical energy charges.

The place’s the Tipping Level?
In the event you at the moment solely use one barista and also you make fewer than 100 milk-based drinks per day, until you’re swayed by the milk focus advantages, you completely mustn’t think about getting an automatic milk resolution, as a result of all it’ll do is drive up your fastened prices. However after 100-a day, issues get fairly advanced…
In some wonderful analysis within the early days of the Übermilk, Seven Miles concluded that fifty% of 1 barista’s time was freed up when the Übermilk arrived, however in addition they identified that that didn’t imply that particular person was not required to do their shift. And if you happen to want one and a half individuals, you want two. After all Seven Miles didn’t learn about prebatched espresso once they did that analysis, in order that’s a drastic imply of turning one and a half baristas into one barista, however that’s a bridge too far for many café homeowners proper now.
The Übermilk Plus can do a number of completely different milks without delay
It’s almost ten years since these machines first hit the bar, and early iterations had points: Cooked milk flavour when sitting idle, as an illustration. Bubble dimension was not as small as steamed milk. They usually couldn’t do a variety of temperatures for additional scorching orders, and many others. These days are behind us with new machines just like the Übermilk Plus, which may faucet in different milks — we’ve even seen Beta Espresso in Sydney serving prebatched espresso by way of the Übermilk in 12 seconds. (Although you bear in mind we just lately established that there’s no style profit in recreating crema in prebatched espresso.)
Figuring out that the fastened prices stand to rise by as a lot as $12.8K per 12 months and the unit prices loads greater than that too, based mostly on Seven Miles expertise, there’s zero monetary profit within the first 12 months. After that, the trade-off between labour saving and stuck value kicks in, however simply remember that if you happen to’re considering of utilizing automation to chop labour prices, over the 200 drinks/day mark, the fastened prices swallow up almost half of the labour financial savings.
Simply preserve one factor in thoughts: In the event you see an automatic milk possibility in a café that’s buzzing with comfortable clients and stuffed with a crew of chilled however impressed trying baristas, it could possibly be that they’ve not parachuted in automation to save cash and kill the excitement. It could possibly be that they need to give their baristas a nicer shift, and so they choose wealthy undiluted milk, served at a gloriously constant temperature.
