In the world of specialty coffee, cold brew has won the hearts of many coffee lovers for its uniquely refreshing taste and rich yet non-bitter flavor. Compared to traditional hot brewing methods, cold brew involves steeping coffee grounds in cold water for an extended period. The low-temperature environment reduces the release of large-molecule bitter compounds, allowing the sweet and acidic flavors to shine through, resulting in a smoother and cleaner overall mouthfeel.

The key to cold brew lies in bean selection. Generally speaking, medium to dark roasted beans tend to release excessive roasted aromas, sometimes resulting in a monotonous bitterness that overshadows subtle flavor layers. In contrast, medium to light roasted beans usually exhibit distinct floral and fruity notes, which can release a richer spectrum of acidity and sweetness during cold brewing, creating a cold brew coffee with clear layers and a three-dimensional flavor profile.

The logic behind cold brew extraction is to steep medium-ground coffee in cold water for an extended period (typically 12 to 24 hours). The low-temperature environment suppresses the release of bitter and astringent substances while promoting the expression of fruit acids and sweetness. This extraction method not only preserves the original flavor characteristics of the coffee beans but also delivers a softer mouthfeel experience. For readers trying cold brew for the first time, choosing a medium to light roasted bean with distinct flavors and suitable for cold brewing is the first step to success.
