When a bag of Yirgacheffe full of citrus and floral aromas is placed in front of you, how to fully present its flavors through the equipment in your hands is something every coffee lover will think about. In fact, as long as you master the key values such as water temperature, coffee-to-water ratio and pouring rhythm, you can easily brew this bright, sweet-and-acidic coffee into something very delicious.

To brew a cup of light-roasted coffee with full aroma, the first thing to focus on is the water temperature setting and the control of the water stream. Water temperature is directly related to the dissolution efficiency of aromatic substances. A suitably higher water temperature can more effectively bring out its fresh notes, while a reasonable pouring sequence ensures that acidity and sweetness reach a comfortable integration in the cup.

Among many classic choices, Qianjie Yirgacheffe Gudingding is very suitable as a starting point. This bean gives off aromas similar to freshly cut oranges and mixed berries, accompanied by an elegant white floral fragrance, and after drinking it you can also feel a long-lasting sweetness like green tea. Because it is a light roast, it especially needs a suitable brewing plan to show its clarity.

When brewing this Gudingding, it is recommended to set the water temperature at 92°C, weigh 15g of coffee grounds, and use a total water amount of 225ml. Use a three-stage pouring method: first pour 30ml of hot water for blooming, then gently pour in circles to 125ml, and after the water level drops, pour the final portion to 225ml. Control the total duration of the whole process at 2 minutes 10 seconds. The citrus profile brewed this way will be very bright.

Besides conventional hot-water brewing, this bean can also show a completely different soft texture when made as cold brew. Long soaking at low temperature makes Gudingding's originally lively acidity become more restrained and gentle, and the smoothness of the mouthfeel increases greatly. It is very suitable for friends who like a fresh, refreshing experience with a prominent tea-like quality to enjoy on a warm afternoon.

To make this cold brew coffee, you can prepare 5°C ice water, weigh 20g of slightly coarsely ground coffee, and set the water amount at 280ml. Use a one-stage, single-pour method: pour the ice water directly into a sealed jar containing the coffee grounds, shake it slightly, then place it in the refrigerator. Keep the total duration at 12 hours. The filtered coffee liquid gives off a very gentle fruity tea aroma.

If you like a richer fruity aroma, Qianjie Ethiopia Huakui is an excellent advanced option. It carries lively notes like abundant tropical fresh fruit, fresh red strawberries and sweet-and-sour passion fruit, and its overall sweetness is very striking. By adjusting the extraction rhythm, you can release this vivid juice-like flavor without reservation.

For Huakui's prominent sweetness, you can fine-tune the water temperature to 90°C, weigh 16g of coffee grounds, and set the total water amount at 240ml. Use a two-stage pouring method: likewise first bloom with 30ml of hot water, then pour directly at a steady pace without stopping the flow until 240ml, shortening the total duration to about 1 minute 50 seconds. A shorter contact time can effectively preserve the lively strawberry-like sweet aroma and avoid off-flavors caused by over-extraction.

Besides the Ethiopian region, if you want to experience different types of fruity acidity, you can also try Qianjie Kenya Xiaofanqie. It contains solid sweet notes like cherry tomatoes, deep black plums and sugarcane brown sugar. Its acidity is bright yet not at all thin, and the aftertaste in the mouth after drinking is very clean and crisp. It is very attractive to people who prefer a bright sweet-and-sour sensation.

To balance this bean's full sweet-and-acidic texture, you can use a water temperature of 91°C, weigh 15g of coffee grounds, and keep the total water amount at 225ml. Use a three-stage pour: after pouring 30ml for blooming, gently pour the second stage to 130ml, and finally pour steadily to 225ml, with the total duration precisely controlled at 2 minutes 05 seconds. Such parameters allow the mellow plum-like body and bright acidity to reach a very comfortable balance.

After mastering these specific brewing data, by moderately fine-tuning the pouring rhythm and water temperature according to the coffee beans at hand, you can gradually figure out the most pleasing taste. Use rigorous values to break down the aroma in the cup, and tailor the plan according to the characteristics of the beans. You will find that making every cup of coffee with bright fruity acidity taste good is actually a very enjoyable thing.
