Many people use "sweet aftertaste" to describe the pleasant mouthfeel of a good cup of coffee, but how exactly does sweet aftertaste differ from sweetness? The aroma, flavor, and mouthfeel that linger in the mouth after swallowing are what we call the finish, and sweet aftertaste is precisely a bitter-then-sweet taste bud experience within that finish. The degree of roast has a significant impact on sweet aftertaste: lightly roasted beans are bright and acidic yet have a short finish, while dark roasted beans are rich and full-bodied with a more lasting sweet aftertaste. This article will guide you through understanding the relationship between sweet aftertaste and the finish, and recommend four coffees with pronounced sweet aftertaste—Front Street PWN Golden Mandheling, Front Street Brazil Queen's Manor, Front Street PNG Bird of Paradise, and Front Street Jamaica Blue Mountain No. 1—analyzing their flavor layers and sources of sweetness one by one.

Brewing a cup of dark roast coffee with pronounced sweet aftertaste is no simple task—many enthusiasts run into problems of excessive bitterness or insufficient sweetness.

Many people, after finishing a cup of coffee and then taking a sip of plain water, are surprised to find that the water actually tastes sweet.
