Protein coffee is having its moment. I had questions. I got answers. Some of them surprised me.
Let me set the scene.
It’s a Tuesday morning. The café I’m in has a new item on the menu, placed between the oat milk flat white and the hojicha latte. It’s called a Vanilla Protein Cold Brew. The menu description reads: cold brew, vanilla protein foam, 25g protein, 150 calories.
The person next to me orders one without hesitation. The barista makes it with the practised efficiency of someone who has already made forty of these today. It arrives looking appealing: a cold brew base, a thick cream-coloured foam, and a light dusting of something across the top.
I look at it for a moment. Then I order one too.
This is the proffee review nobody asked for. You’re getting it anyway.

What proffee actually is
Proffee, or protein coffee for the uninitiated, is what it sounds like: coffee with protein added in some form. The earliest versions were simple and a bit rough. You stirred a scoop of whey protein powder into iced coffee and hoped it dissolved, and if you weren’t thorough, it stayed lumpy.
The café version is much more refined, and it sits somewhere between a morning coffee and a treat. The protein arrives as a cold foam, whipped and stable, that sits on top of the coffee rather than mixing into it. Sometimes it’s a protein-enriched milk base. At the more experimental end, it’s a protein shot added to an espresso drink, the way a flavour shot would be.
Large chains have started adding protein options to their menus, and independent cafés are offering them often enough that this doesn’t look like a passing fad. Like mushroom coffee, it appeals to people who want their morning cup to do more than wake them up.
The case for it
I’ll make the case for proffee fairly before I get to my reservations, because the case is reasonable.
Many of us don’t eat much protein at breakfast. Breakfast is the meal most likely to be cut short, skipped, or reduced to whatever takes the least preparation. Coffee is one of the few things many people reliably have in the morning.
If you can add a meaningful amount of protein to the drink someone was already going to have, with little change to the ritual, that’s useful. For some people it’s an easy way to get a bit more protein into the morning.
There’s also a wellness angle, and it’s a big part of why proffee sells. More people want drinks that taste good and feel like they’re doing something for them, whether that’s protein, adaptogens or less sugar. Proffee responds directly to that wish.
What it actually tasted like
The Vanilla Protein Cold Brew I ordered was good. I want to be precise: not extraordinary, not a revelation, but pleasantly good.
The cold brew base was clean and smooth, well extracted and properly chilled. The protein foam had a mild vanilla sweetness that complemented the coffee without overpowering it. The texture surprised me most. The foam was stable enough that you got a layer of it in every sip, rather than it dissolving straight into the coffee, so the flavour stayed consistent all the way through the cup.
What it wasn’t was coffee in the way a pour-over is coffee, or a filter, or even a well-pulled espresso. The protein pushes it into the territory of a coffee-based wellness drink. That’s fine, and it’s probably what most people who order it want.
The question is whether that’s what you want when you sit down with a cup.
My reservations, honest ones
Here they are, plainly.
Protein has a flavour. Even the best protein powders, clean-label whey included, and the plant-based alternatives all bring something to the cup that isn’t coffee. There’s a slight thickness and a faint aftertaste that lingers after the coffee notes have faded. Nothing offensive, but something is there.
If you care deeply about what coffee tastes like at its best, the brightness of a washed Ethiopian, the depth of a natural process, or the particular character of a well-sourced single origin, the protein will compete with that. It will round off the edges of the flavour in ways you may not want.
Proffee isn’t built for those people. It’s built for people who want a filling, enjoyable morning drink that happens to be based on coffee. Those are different things, and both are legitimate.
Who it’s actually for
If your morning cup is mostly about ritual and taste, and you’re the person who notices when the barista has changed the grind and wants to talk about it, proffee probably isn’t your drink.
If your morning cup is about getting the day started well, feeling good, staying full until lunch, and enjoying something that tastes better than a protein shake from a shaker bottle, proffee might be exactly your drink. There’s no shame in that. Those are sensible priorities.
The café world has always been broad enough for both. Pour-overs and frappuccinos coexist. Single-origin tasting menus and caramel macchiatos coexist. Proffee and filter coffee can coexist too.
The only mistake is treating one as the standard by which all the others must be judged.
Would I order it again?
Honestly, yes. Not every day, and not instead of my filter coffee when I want to taste what’s in the cup. But on a morning when I’ve skipped breakfast and want something that works as both a coffee and a proper start to the day without stopping for food, yes.
The Vanilla Protein Cold Brew earns that morning.
Rating: 7/10 as a functional morning drink, 5/10 as a coffee. That isn’t a criticism. It’s a clarification of what the drink is trying to be.

Have you tried proffee, café-made or at home? Did the protein change the experience, or did you barely notice?
