Good Cup · 6 November 2026
The people who prepare the cup for you, then the coffee, then the equipment. The same beans taste different in different hands, and the cafés we rate highest are, almost without exception, the ones with skilled people behind the bar.
The person making your coffee has the largest effect you can control as a customer. Grind size, dose, water temperature and timing change every cup, and they drift through the day as the beans age and the room warms. A trained barista tastes and corrects; an untrained one repeats the recipe and hopes. That is why 94 % of the cafés we rate Outstanding have someone on the team with championship results, against 6 % of Solid Specialty cafés.
The coffee itself sets the ceiling. A roaster decides which green coffee to buy, from which farm, and how far to roast it. A café that pours a strong roaster starts higher: 86 % of our Outstanding cafés pour a roaster we rate Top or World-class. Some cafés roast their own, like Origin, Calico and Formative in London. Others serve a roaster from elsewhere, like 4850 in Amsterdam, which serves La Cabra from Denmark.
Origin and processing decide what the cup can taste like. A washed coffee from Ethiopia and a natural from Brazil are different drinks before anyone touches them. Cafés that list the farm, the variety and the process on the menu are telling you they chose the coffee on purpose.
Equipment matters less than people think, and more than nothing. A good grinder and a stable espresso machine let a skilled barista repeat a great cup. They do not make an unskilled one good.
Water is the hidden variable. Coffee is more than 98 % water, and hard or chlorinated water flattens flavour. Serious cafés filter or remineralise theirs.
