The flavor logic of light-roasted beans is "preservation": the roasting time is short, so the floral and fruity aromas and acidity of the origin are retained in greater amounts, and when brewed properly it is a bright, clean cup. In the light-roast version of Qianjie Yirgacheffe Gudingding, the citrus and green tea sweetness are crystal clear, and the acidity is a lively fruit acidity rather than a sharp, biting sourness - the sweet-and-sour sensation of light roasting is its entire meaning.

The taste of a cup of pour-over is written jointly by the origin's terroir, the bean variety, the processing method, the roast level and the brewing technique. Light-roasted beans lean toward floral and fruity notes, while medium-roasted beans excel in sweetness and body; when the parameters change, the order in which aromas are released also changes, so guessing flavor from a name is not reliable.

Brewing light-roasted beans requires "giving enough": water temperature above 92°C, a slightly finer grind, and full extraction, so that the sweet-and-sour structure is complete. These light-roasted beans are all brewed this way.

Qianjie Yirgacheffe Gudingding's flavor leans toward citrus, berries, floral notes and a green-tea-like sweetness; when brewed as a light-roast pour-over the aroma is clearly expressed, and after making it into cold brew the acidity mellows considerably.

Qianjie Ethiopia Hua Kui's aroma falls in the category of tropical fruit, strawberry and passion fruit; with its lively sweetness, it suits pour-over, iced pour-over and cold brew alike.

Qianjie Kenya Little Tomato presents a flavor combination of cherry tomato, smoked plum and yellow sugar; the acidity is bright and well-supported, suited to drinkers who seek a juicy mouthfeel and a crisp finish.

Storage sounds trivial, yet it determines how long a bean's flavor can last. Unopened beans can simply be kept at room temperature away from light; after opening, it is best to put them in a well-sealed container and expel as much air as possible. There is also a method for observing flavor: first smell the dry aroma, then after sipping appreciate the sweetness and the finish; iced drinks and milk coffee will differ from hot drinks in their expression. Brew the same bean several times with different parameters and write it down, and a cup suited to your own taste will become easier and easier to reproduce.

When choosing beans, you can first ask yourself two questions: what flavor do you want more, and how many parameters are you willing to adjust for it. Beans with prominent floral and fruity notes are like precision instruments - changes in water temperature, grind and flow rate all get written into the cup; blends in the nut-and-cocoa direction are like reliable companions, with stable everyday output. If several people at home have different tastes, choosing a balanced bean as the shared option and then pairing single origins for those with preferences is smarter than hoarding homogeneous beans.

When making pour-over, fix the coffee-to-water ratio and the total amount of water first, and fine-tune mainly through the grind. If you taste sharp acidity, consider that extraction is insufficient; if you taste dryness in the finish, slow the pouring, reduce the agitation force or shorten the overall duration - change only one thing at a time, then compare after the change.

If you usually switch between brewing devices and your taste swings between strong and weak, you might keep two types of beans on hand: one as an everyday staple, stable and easy to drink; the other reserved for moments of curiosity, to experience jasmine floral notes, citrus acidity or the layers of anaerobic fermentation. Taking your drinking habits and flavor preferences into consideration together will make your approach to choosing beans clearer.
