2, look at the place of origin: coffee beans produced in different regions will have different characteristics in color, aroma and taste, just like Brazil, the coffee produced is fuller, the taste is sweet, and the sour taste is basically not felt. Due to the mild and humid environment, coffee produced in Colombia has good characteristics of sweetness in acid and bitterness in bitterness. I suggest that you can look at coffee beans from different regions when choosing, which is more in line with your own taste.
