The fruit acidity and sweetness in coffee beans blend with each other, delivering a rich and succulent drinking experience reminiscent of ripe fruit. The key to brewing this type of bean lies in using a reasonable water temperature, coffee-to-water ratio and pouring rhythm to harmoniously extract the bright fruit acidity and caramelized sweetness from within the coffee grounds, presenting a clear yet full-bodied flavor in the cup.

Light-roast sweet-and-sour style coffee beans are usually dense in texture, and their aromatic compounds volatilize in a rather lively manner, so they need to rely on precise water temperature to awaken the aroma, while being paired with a steady flow rate so that the sweet compounds and acidity dissolve in sync, making the mouthfeel appear softer and fuller.

Taking the classic Ethiopian region as an example, Qianjie Yirgacheffe Gudingding displays a fresh citrus note and white flower aroma, with a sweet tea finish in the tail end. When brewing this light-roast bean, it is recommended to prepare 91°C hot water, use 15g of coffee grounds, pour in 225ml of water, and keep the coffee-to-water ratio at 1:15.

For the pouring method, a three-stage pour is recommended: first pour 30ml of hot water for a full 30-second bloom, then steadily pour 95ml in circles until reaching the 125ml mark, and once the liquid level drops slightly, continue pouring the remaining 100ml, keeping the total extraction time at 2 minutes 10 seconds. This staged rhythm fully awakens the floral and fruity fragrance and allows the sweetness to steadily envelop the acidity.

If you prefer a bean with rich layers and a tropical fruit character, Qianjie Colombia Sidra displays a juicy flavor of ripe passion fruit, grape and apricot, with a very lively interplay of acidity and sweetness, making it suitable for highlighting its sweetness by adjusting the brewing technique.

When brewing Qianjie Colombia Sidra, you can try a two-stage pour to accentuate its abundant juiciness. Use 16g of grounds, paired with 90°C water temperature and 240ml total pouring volume. First pour 40ml of water and bloom for 35 seconds, then smoothly pour in small circles at the center until reaching 240ml to finish, keeping the total time at 1 minute 50 seconds, to obtain a very full juicy sweet-and-sour sensation.

If this Colombia Sidra is used for espresso extraction, its mellow sweetness can be intensified by adjusting the grind size and yield. Use 18g of coffee grounds, under the standard 9 bar extraction pressure, set the grind size to a fine powder state, and extract 36g of espresso within 26 seconds; after adding water to make an Americano, it presents a lively complex fruity aroma and a syrupy sweetness.

For drinkers pursuing a combination of delicate floral aroma and soft sweet-and-sour notes, Qianjie Panama Hacienda La Esmeralda Red Label Geisha brings an elegant note of jasmine, bergamot and citrus black tea. When facing light-bodied high-altitude beans, extraction requires even more attention to the gentleness of the water flow and temperature matching.

When brewing this Red Label Geisha, it is recommended to use 92°C water temperature, take 15g of grounds, paired with 240ml of hot water, for a coffee-to-water ratio of 1:16. Use a three-stage pour: 40ml of water for a 30-second bloom, a gentle second pour to 140ml, and a third pour to top up to 240ml, keeping the total time at 2 minutes 20 seconds. A slow extraction with a fine stream allows the delicate floral and fruity aroma and the tea-like sweet finish to unfold layer by layer.

When brewing sweet-and-sour style coffee beans day to day, as long as you understand the flavor characteristics of different beans and carefully adjust the water temperature, pouring stages and extraction time, you can easily taste the captivating flavor of acidity and sweetness complementing each other in every cup of black coffee.
