Those who chase crema often reach a fork in the road: the thicker the crema, the richer the flavor, but the delicate floral and fruity notes tend to blur along with it. Richness and clarity are like the two ends of a seesaw—finding your own balance point is more worth pondering than simply piling on more crema.

A coffee bean with balanced acidity and sweetness is not simply a matter of adding sourness and sweetness together; rather, it has a bright sensation on entry, followed by a soft sweetness, with a finish that is neither sharp nor astringent, and is not overpowered by bitterness.

To talk about single-origin pour-over coffee beans with a mild balance of acidity and bitterness, we have to start with the actual taste in the cup.

From the day coffee beans finish roasting, the internal gases, aromatic compounds, and extraction state are constantly changing. When made into an SOE Americano, these changes are stretched out by the hot water: drink it too early, and the acidity may seem jumpy while the aroma has yet to unfold; once it enters the right stage, the transition between acidity and sweetness becomes smoother, and the fruit notes are more complete. Therefore, judging [more…]
