Protein now seems throughout the whole meals and beverage business. Supermarkets worldwide inventory protein-fortified yoghurt, milk, and cereal, and even protein sodas, as well being and wellness developments form what shoppers purchase.
Espresso is following the identical sample. The world protein espresso market is predicted to develop from US$6.67bn in 2026 to US$11.53bn by 2034, and to date, chains have led the best way. Starbucks, for instance, launched protein chilly foam in Europe, North America, and Asia-Pacific between September 2025 and June 2026, and the tempo alerts a class that’s more likely to final.
Specialty espresso outlets, specializing in high quality above all else, have a gap to supply protein with extra intent. As a substitute of including elements that complicate the menu, they will begin with one of many easiest elements they already inventory: milk.

Protein has change into an on a regular basis expectation
Protein is not a priority for athletes. Circana’s analysis discovered that 48% of US adults are actively making an attempt to eat extra protein. In Europe, in the meantime, seven in ten shoppers throughout all age teams are being attentive to protein of their weight-reduction plan.
The motivations for growing protein consumption are broad. Shoppers more and more hyperlink protein to fullness, improved power, and higher muscle restoration, backed by scientific analysis. Protein will increase satiety and urge for food management by reducing starvation hormones, together with ghrelin (the hormone that tells your mind if you find yourself hungry), triggering the discharge of satiety hormones like GLP-1, and slowing digestion to delay the return of starvation.
The rise in GLP-1 remedy use is a more recent driver. Gallup’s survey discovered that 11% of US adults presently take GLP-1 drugs for weight reduction, up from 3% in 2024, whereas different analysis estimates that 8.25 million folks within the UK have taken, are taking, or are contemplating taking GLP-1 weight reduction drugs. These medication suppress urge for food, so customers are suggested to prioritise protein as a way to protect muscle mass whereas losing a few pounds.
Different analysis from Circana exhibits that 65% of GLP-1 customers actively search extra protein at each meal, together with breakfast. For a every day behavior like espresso, this raises a sensible query. Prospects who need to improve protein consumption at each meal might quickly anticipate finding it of their morning espresso.
Why espresso is a pure touchdown spot for protein
Protein merchandise work finest when integrated into present client habits, and few are as common as espresso. The 2026 Nationwide Espresso Knowledge Tendencies Fall Report discovered that 66% of US adults drank espresso previously day, with specialty espresso consumption at a brand new report excessive. Milk-based espresso drinks account for a lot of this development, so protein comes from an ingredient prospects anticipate and know.
Dairy protein additionally issues for physiological causes. Analysis from 2024 explains that leucine, an amino acid present in high-quality proteins comparable to milk, triggers muscle protein synthesis. About 2.5 to 3g of leucine in a single meal is required to completely set off muscle development, which requires 25 to 35g of protein per meal.
Moreover, the mix of casein and whey proteins in milk helps muscle development. Whey is absorbed in about 60 to 90 minutes, spiking blood amino acid ranges, whereas casein absorbs slowly and releases amino acids over a number of hours. This offers a right away surge of amino acids for muscle constructing and a sustained trickle to stop muscle breakdown.
Many individuals drink espresso earlier than train, and caffeine is nicely documented as a efficiency support. The Journal of the Worldwide Society of Sports activities Vitamin discovered that caffeine persistently improves train efficiency at doses of three to 6mg per kg of physique mass. The mix of caffeine and protein can also be necessary; caffeine fuels efficiency throughout exercises, whereas protein protects your muscle tissue and begins the restoration course of after, so a milk-based espresso can ship a number of advantages.
Protein consumption is usually concentrated in night meals, however analysis suggests spreading protein evenly throughout the day retains a gentle provide of amino acids in your blood to maximise muscle restore and stabilise power. This implies high-quality milk-based espresso drinks, consumed within the mornings, could be a invaluable protein supply.
New alternatives for espresso outlets
Milk has lengthy been added to espresso, altering texture, sweetness, and dietary worth. Protein follows the identical intuition, however the scale of funding is new. Starbucks launched protein lattes and protein chilly foam throughout the US and Canada in September 2025, after which in Europe in April 2026 and Asia-Pacific markets from June 2026. Dunkin’ adopted with its personal protein milk in January 2026, signalling a serious shift in client preferences.
The broader market is transferring in the identical course. Circana tasks that households utilizing GLP-1 drugs will account for 35% of all US meals and beverage items bought by 2030, that means demand for protein-enhanced merchandise, together with espresso, will proceed to rise.
Protein is a query of margin in addition to vitamin for café homeowners. Starbucks costs US$1 so as to add protein milk and US$2 for protein chilly foam, and CEO Brian Niccol has referred to as the platform “extremely incremental”, that means it provides gross sales fairly than changing present ones. In supermarkets, fairlife ultrafiltered milk sells at a 190% premium per ounce over common entire milk at Walmart, in response to DairyReporter.
Client willingness to pay issues as a result of main chains like Starbucks, Dunkin’, and Pret A Manger have dropped plant-milk surcharges, decreasing what cafés can cost for various milks. A high-protein milk choice offers prospects another excuse to commerce up.
But it surely additionally poses operational challenges
Including protein to take advantage of might be difficult. Whey isolate is the quickest method so as to add protein to drinks at residence, but it surely is likely one of the tougher choices in a café. It’s because whey proteins change into much less soluble as a liquid’s acidity nears its isoelectric level (a impartial pH electrical cost). As filter espresso is acidic, normally between 3.97 and 4.25 pH ranges, whey proteins are more likely to curdle or kind a grainy texture.
Warmth from steaming additionally makes whey isolate proteins clump. Researchers at Wageningen College discovered vital aggregation above 70°C at pH 4.0 and 4.5, and the Wisconsin Middle for Dairy Analysis says drink producers normally want stabilisers, comparable to pectin, to mitigate clumping.
Powder additionally provides a preparation step. Starbucks, which makes use of powder, blends 2% milk with unflavoured protein powder and prepares it contemporary every day. For cafés that compete on texture and consistency, protein that’s already within the milk is a extra dependable choice.
The high-protein dairy choices for espresso
Cafés now have 4 methods to supply higher-protein milk drinks.
- Whey-blended milk: Commonplace milk blended with whey isolate. Starbucks’ model provides 12-16 g of protein to a grande latte. The protein dose is excessive, but it surely requires an additional step and might have an effect on texture in sizzling espresso.
- Ultrafiltered milk: Milk passes by means of a membrane underneath strain, concentrating the protein whereas water, some lactose, and minerals go by means of. It has extra protein and fewer sugar than normal milk, with a well-known style.
- Protein-fortified milk: Milk with added milk protein focus. Arla’s UK Protein semi-skimmed milk incorporates 5.5g of protein per 100ml, which Arla says is 53% greater than normal semi-skimmed.
- Double milk: Milk with some water eliminated, which concentrates protein, fats, and pure sugars. It provides physique and sweetness and improves foam construction. As a result of the sugars focus, it’s not a lower-sugar choice.
What’s double milk?
MILBOK, made by BeFood, is a key participant within the double milk class. The idea resembles double cream: a richer, extra concentrated type of single cream. Double milk is made by eradicating some water, with out including something.
The concept started in barista competitions, the place rivals focus their very own milk to construct sweetness, physique, and mouthfeel. The commonest technique is freeze-distillation. Baristas freeze entire milk and let it soften slowly, so the water-rich portion drains away, roughly halving the quantity. The World Barista Championship guidelines permit this, so long as the method makes use of no elements or components.
“MILBOK’s double milk incorporates 5.5g of protein and 5g of fats per 100ml, towards 3.2g and three.5g in entire milk,” says Alex Shilov, advertising supervisor at MILBOK. “That is about 70% extra protein than entire milk and about 5 instances the protein of a typical barista oat drink.
“The one ingredient is cow’s milk, with no components or powders. The method reduces 2 litres of milk to 1 litre, and all 8.6g of carbohydrate per 100ml comes from pure milk sugars.”
Guests can style double milk at upcoming European festivals: the Ljubljana Espresso Competition on 26 and 27 September, the place MILBOK is a sponsor, the Prague Espresso Competition on 24 and 25 October, and Rotterdam Espresso Fest from 5 to eight November.
The advantages of double milk
Past style and texture, double milk affords dietary advantages.
“A 250ml serving of MILBOK incorporates roughly 14g of protein from the milk alone, the equal of two eggs,” Alex says. “As a result of protein is of course a part of the milk, the product steams like abnormal milk. We advocate steaming to 55°C to create a steady microfoam appropriate for latte artwork.
“The concentrated milk sugars additionally add pure sweetness, which may cut back the quantity of syrup a drink wants,” Alex provides.
Consistency is one other benefit. Handmade competitors milk takes greater than 10 hours to arrange and varies in style between batches, whereas a business product delivers the identical specification in each carton. Sealed cartons additionally hold for as much as six months at room temperature (most 25°C), liberating fridge area and decreasing waste. As soon as opened, MILBOK advises refrigerating double milk and utilizing it inside three days, so cafés ought to match carton sizes to their volumes.
This makes it extra simple to construct a premium beverage tier. A protein flat white or cappuccino affords a richer texture, and a soiled espresso advantages from denser milk to take care of a separate layer beneath the espresso.
Past espresso
As demand for non-coffee drinks soars, even outpacing espresso at chains like Black Sheep and Clean Road, specialty cafés have a chance to develop the usage of high-protein milks.
“Double milk works nicely in matcha lattes, tea lattes, and sizzling chocolate, and plenty of cafés are on the lookout for protein choices throughout their entire milk-based menu, not solely espresso drinks,” Alex says.
Matcha and sizzling chocolate specifically profit from the additional physique and sweetness. Each are naturally bitter, with matcha having grassy, hay-like flavour notes, so the concentrated sugar in double milk offers pure sweetness.
Protein is not restricted to gyms and sports activities vitamin. Shoppers now search for it in cereal and sodas, and low is the following place many anticipate finding it. Chains comparable to Starbucks have proven that prospects pays for protein choices, whereas the expansion in GLP-1 use suggests demand will proceed.
Specialty cafés can serve high-protein milks in several methods, and they need to check choices towards their prices, prospects, workers, and gear earlier than including protein to their menus.
