Processing, quality and crema: where specialty coffee is moving
In specialty coffee, quality is built long before a bean reaches the cup. Those working across the chain have known this for some time: variety, microclimate and altitude still matter, but post-harvest processing is playing a growing role in shaping the final sensory profile, alongside the factors tied to origin. The shift is most visible in certain parts of the sector, where producers, roasters and buyers are speaking a more technical and more precise language.
Colombia is one of the clearest examples of that change. The country has built a solid reputation in international competitions and auctions, helped by its microclimates, varieties and producer and research networks. In that context, when a lot performs well through a particular fermentation or a carefully executed drying method, the result does not stay isolated: it becomes easier for others to observe, adapt and repeat. Competitions and auctions end up working as accelerators, rewarding quality in visible terms and giving a concrete incentive to experiment.
Processing is now the area where creativity has the most room to move. Controlled fermentations, co-fermentation with fruit or selected yeasts, and more advanced drying systems can produce very different cup profiles from the same terroir. That opens real commercial opportunities, but it also brings a risk that is often discussed less often: exposure. Experimenting on small lots, treating the first trials as learning phases rather than models to scale immediately, and protecting those who take on the financial risk of innovation are practices the sector is trying to formalise. The question is not only how to create new flavours, but how to ensure that value also returns to the people who carried the initial risk.
From recognising value to building it
There is a useful parallel with wine, where the figure of the vigneron has gradually come to stand alongside terroir in shaping a bottle’s reputation. Something similar is happening in specialty coffee, at least in part of the category: processing is becoming a signature, an identity marker through which producers and farms can stand out. In some cases, that shifts the balance from being a price taker to trying to negotiate price with greater confidence. But the move only works if the market is willing to read that difference, and if technical skills are not concentrated in just a few pockets of the chain.
That is where training programmes such as those run by Coffee Quality Institute, an international coffee-quality organisation, come in. The group is expanding beyond sensory evaluation into post-harvest management, with an emphasis on building good practice and learning how to structure controlled experiments. It is a subtle but important shift: from reading quality after the fact to actively building it where coffee is transformed.
Crema: a detail specialty coffee still argues over
Specialty coffee is comfortable questioning assumptions that once seemed settled. The recent debate around espresso crema is a good example. For a long time, the reddish-brown foam on top of a shot was treated as a visual sign of freshness and quality. Today, however, some professionals are asking whether it can also contribute bitterness, astringency and a drier mouthfeel.
Michael Harris Conlin, a three-time Philippine Barista Champion and founder of Henry and Sons, a coffee company, brought that question to the stage of the World Barista Championship, presenting a device designed to separate crema from espresso. In the first round, his espresso received the highest score. It is not a final answer, but it is a useful sign of how seriously the topic is being taken in competitive coffee.
Still, the issue is more balanced than the shorthand version suggests. Crema is not only a possible source of bitterness: it also contributes to structure, to the release of volatile aromatics and to the overall mouthfeel of the drink. Removing it is not automatically an improvement, but one variable among many, depending on the coffee, the roast profile and the experience the barista wants to create. That may be the most revealing point of all: the fact that such a specific question now has space in specialty coffee says a lot about how the category has evolved. Espresso is no longer just a ritual to be repeated, but a field of sensory testing where even familiar conventions can be reconsidered.
Processing, education and sensory identity are different sides of the same shift. In quality coffee, value is increasingly built with more precise tools. And in this part of the sector, there is less and less appetite for accepting the obvious as final.
