Why Cafés Filter Crema From Americanos | Clean Taste vs Traditional Espresso

 This question is something I’ve noticed quite frequently over the past year while café hopping. Of course, it’s not a new topic for me—I’ve already touched on it multiple times in previous articles. Personally, I’ve encountered it so often that I’ve almost become “desensitized” to the idea of filtering crema from an Americano. But if we take a more rational step back, the reason many cafés now promote over-extraction–style Americanos is fairly clear: they’re chasing a cleaner, more stable, and smoother mouthfeel, while trying to avoid unpleasant flavors.

From my point of view, over-extraction–based Americanos and traditional “espresso + water” Americanos follow fundamentally different extraction and brewing logics. In that context, removing the crema can be a 1 + 1 > 2 kind of optimization. However, if it’s just a standard espresso shot that’s brewed normally, then filtered for crema, and only afterward diluted with water, I personally feel it would be better to leave the crema intact. After all, that crema is the soul of the espresso.

So why do so many cafés filter out the crema when serving an Americano? It’s undeniably a widespread and discussion-worthy phenomenon in today’s specialty coffee scene. By “crema,” I’m referring to the oily substances in coffee beans (along with some ultra-fine coffee particles). Strictly speaking, this isn’t true oil. Rather, it’s a stable, oil-like foam formed through emulsification under high pressure—what we commonly call crema.

Not long ago, I talked about how crema is often considered the soul of espresso, and I believe many people still hold that view. In traditional Italian coffee culture, a perfect espresso is expected to have a thick, fine, brown crema on top. It’s seen as a marker of freshness and successful extraction, contributing to a richer mouthfeel and longer-lasting aroma. In some evaluation systems, the color and thickness of the crema are even key scoring criteria. What we’re seeing now is, to some extent, a departure from that tradition—a redefinition of how we understand espresso’s role as a base in beverages like the Americano.

I think this shift also reflects how people’s flavor preferences have evolved. The industry has gradually moved away from the classic pursuit of “intense, bitter, and heavy-bodied” coffee toward a preference for “clean, sweet, and transparent” flavors. Under this new paradigm, crema can sometimes work against the desired profile. Crema contains a relatively high concentration of compounds such as quinic acids, which can introduce sharp, lingering bitterness and astringency.

This becomes even more apparent now that many espresso programs favor light or light-medium roasts, aiming to highlight fruity notes, floral aromas, and bright acidity even in espresso. In such cases, the bitterness and harshness associated with crema can easily overshadow the coffee’s elegant origin characteristics.

In China, drinking espresso straight is still relatively uncommon, but I’d still like to point out one thing: if you are going to drink espresso on its own, it’s important to stir the crema thoroughly into the liquid before drinking. Otherwise, the crema can actually detract from the overall mouthfeel. Also, the flavor of crema changes over time. Fresh crema tastes very different from crema that has been sitting for a few minutes—it oxidizes and breaks down, becoming less pleasant. In that sense, the problem isn’t always the crema itself, but sometimes the way we approach drinking it.

Another key consideration is consistency. The amount of crema varies from shot to shot, which means each Americano can look slightly different and deliver a subtly different initial taste. If there are roasting defects, crema can further amplify undesirable flavors such as burnt bitterness, smokiness, or rubbery notes. By filtering out the crema, cafés can make every cup look clear and uniform, while also reducing the amplification of flavor flaws in the finished Americano.

On top of that, cafés today are highly visual spaces. The appearance of a drink matters. When espresso is poured directly into water, the crema floats on the surface, and that foamy layer isn’t always visually appealing. Sometimes it breaks apart awkwardly or clings to the sides of the cup. To many consumers, that’s the very definition of “not photogenic.” It’s only natural, then, that cafés would try to avoid this and gradually adopt crema filtration as a standard practice.

Seen this way, filtering crema from an Americano is essentially a deliberate choice—a form of flavor selection and mouthfeel optimization. It also introduces a new layer of dialogue at the point of ordering. If you’re someone who loves crema, it’s worth asking whether the café filters it by default. And if you enjoy the richness and heavier body that crema brings, you may want to ask the barista not to filter it out.

In the end, there’s no right or wrong when it comes to flavor and texture—only personal preference. In that sense, the Americano has gained yet another dimension of choice. And perhaps, on a deeper level, this trend reflects a more nuanced understanding of quality within the industry, as well as a growing respect for the diversity of consumer tastes.
