Non-coffee drinks gain ground as functional beverage needs shift

Coffee is still the anchor, but the job description is changing

Coffee is not going away. What is changing is why people reach for something in a cup, and that shift is opening a real lane for non-coffee drinks that can do more than impersonate an iced latte. A FoodNavigator-USA analysis syndicated on EU Agenda, drawing on Spate data, makes the key distinction plainly: consumers are not simply abandoning coffee, they are looking for functional upgrades around it.

That matters because it changes the whole playbook. The old non-coffee story was substitution, build something that tastes coffee-like and hope it captures the same habit. The newer story is more interesting and much harder to fake: build a beverage with a clear job to do. Some shoppers want energy without the crash, some want something lighter on the stomach, and some want focus, hydration or calm. That is why tea-based drinks, mushroom beverages and functional waters keep showing up with better-defined purposes instead of just caffeine mimicry.

Why this is more than a replacement trend

The smartest takeaway from this category shift is that consumers are buying into rituals, not just ingredients. A mushroom latte, a functional water or a tea-based energy drink does not need to behave like coffee if it delivers the feeling the buyer wants at that moment. That is a much better business opportunity than trying to win a head-to-head taste contest with a cup of drip coffee.

It also explains why the most successful non-coffee beverages are being positioned around daypart behavior and wellness goals. Morning is not the only moment that matters anymore. Midday hunger, post-workout appetite, afternoon brain fog and the desire for steadier energy all create openings for drinks that can claim more than refreshment. In that sense, the non-coffee aisle is being rebuilt around use cases, not just flavors.

Protein is the clearest proof that function is moving into the cup

Protein is the most revealing part of this shift because it shows how far beverage thinking has moved beyond simple caffeine replacement. A protein coffee is not really competing with coffee on coffee’s terms. It is blending energy, satiety and convenience into one format, and that is a very different promise.

For protein strategists, the opportunity is not just “add protein to coffee.” The stronger angle is problem solving. A beverage with protein can make more sense than coffee alone when the consumer wants to stay full longer, smooth out a rushed breakfast, recover after exercise or get something that feels more nutritionally complete without becoming a full meal. That is where the whitespace is real: not in copying coffee, but in meeting a need coffee never claimed to solve.

The chains are already testing the format at scale

The clearest proof that this is not just a theory is how aggressively major chains are building protein coffee into menus. Starbucks launched Protein Lattes and Protein Cold Foam in September 2025, and the company says those drinks can deliver up to 36 grams of protein per grande, which it defines as 16 oz. Starbucks also says protein-boosted milk and Protein Cold Foam can be added to nearly any beverage, with customers able to customize 90% of beverages using those options across the U.S. and Canada.

Starbucks has been explicit about the consumer logic behind the rollout. Citing the 2025 IFIC Food & Health Survey, it said 70% of Americans are trying to consume protein, and that protein has been the nutrient most Americans say they are trying to consume for five straight years. The chain later said its protein drinks were bought most often on Fridays at 8 a.m., which is a useful clue: this is not only a gym-adjacent format. It is becoming part of the morning coffee habit.

Dutch Bros is taking a similar path with a dedicated Protein Coffee menu that includes protein latte, protein mocha and protein coffee variants. Its own positioning is straightforward: amp up your coffee with protein, and high in calcium. Peet’s Coffee has also moved into the space with products like Vanilla Protein Latte, Golden Protein Latte and Iced Golden Protein Latte, with the Golden Protein Latte offering 20 grams or more of whey protein in a medium size.

What the market data says about the size of the bet

The broader market numbers suggest this is not a niche experiment. One report estimates the global functional coffee market at US$21.5 billion in 2024, with growth to US$48.1 billion by 2035. Another pegs the global protein coffee market at US$1.64 billion in 2024. Even if those estimates come from different market lenses, they point in the same direction: the category is getting materially larger, and function is the growth engine.

That growth is also happening alongside other format shifts. A market overview of mushroom drinks includes mushroom coffee, teas and elixirs, and frames the category around health-conscious consumers and interest in natural and organic products. Separately, drinktec has noted that tea is increasingly being used as a base for ready-to-drink energy drinks and functional beverages because tea already brings caffeine and antioxidant properties to the table. In other words, the industry is not waiting for one winner. It is building a wider toolbox of ingredients and formats that can be tuned for alertness, calm, digestion, hydration or satiety.

So is there whitespace, or just another wellness wave?

The honest answer is both. There is real whitespace for protein-forward beverages, but only when the product is solving a specific need state. If the drink is only there to borrow coffee’s cultural power, it is probably just another adjacent wellness trend. If it can credibly own balanced energy, hunger management, or post-exercise recovery, then it starts to look like a distinct beverage occasion.

That is why the next round of winners will likely be hybrid formats, not purist replacements. The strongest products will not try to beat coffee at being coffee. They will do something coffee does not do well enough: keep people full, deliver steadier energy, and make function feel like part of the daily ritual instead of an extra task.
