Black coffee and milk coffee do not have the same requirements for beans. Black coffee needs aroma and sweetness that can stand on their own, while milk coffee needs the coffee liquid to have enough concentration and body to retain a clear flavor after milk is added. First decide whether milk will be added to the cup, then choose the style of bean; this makes it easier to pick a suitable one.

Pour-over flavor is mainly determined by origin, variety, processing method, roast level and brewing parameters. Light-roasted beans commonly show floral and fruity notes, while medium-roasted beans have more prominent sweetness and body; water temperature, grind size and pouring rhythm change the order in which aromas are released, so you cannot judge by bean name alone.

Around the direction of "Yirgacheffe coffee beans suitable for pour-over," you can first break the choice into several parts: flavor preference, commonly used equipment, drinking temperature and daily frequency of use. When choosing between black coffee and milk coffee, you might first determine which one you care about more, then use other conditions to filter. This preserves individuality while also allowing the beans to show clear characteristics in actual brewing.

Qianjie Granja Estate Geisha has notes of orange blossom, guava, apricot and strawberry jam, with rich natural-process flavor, suitable for observing layers with pour-over.

Qianjie Colombia Sidra has passion fruit, blueberry, grape and apricot flavors, with obvious juicy character; iced pour-over, cold drip and SOE can all present its aroma.

Qianjie Panama Hacienda La Esmeralda Red Label Geisha leans toward jasmine, bergamot, citrus and black tea aromas, with a clean and delicate mouthfeel, suitable for slow sipping.

Besides flavor direction, the roast date and storage method of the beans also affect actual performance. After opening, coffee beans should be sealed as much as possible and placed in a cool, dry place; buying according to daily usage makes it easier to observe flavor changes. When brewing, first smell the dry aroma, then taste the entry, sweetness and finish; if the aroma is insufficient, check whether the grind is too coarse or whether the beans have been stored too long. For the same bean, hot drinking and iced or milk-added performance may also differ; after recording parameters a few times, you can usually find the cup style that suits you better.

You can also consider "flavors you like" and "brewing difficulty you can accept" separately. Beans with obvious floral and fruity notes often require more careful control of water temperature, grind and pouring rhythm, while blends in the nutty cocoa direction are better suited to daily brewing where stable output is sought. If several people at home drink coffee, first choose a balanced bean as a base, then add single-origin trials according to personal preference; this makes comparison easier than buying many beans of similar style at once.

For pour-over, you can first fix the coffee-to-water ratio and total pouring amount, with grind size as the main adjustment item. If the entry is sharp, check whether extraction is insufficient; if the finish is dry and astringent, reduce agitation or shorten contact time, changing only one variable at a time.

If the equipment you usually use, drinking habits or taste change, you can also divide the three beans into daily and exploratory categories: one responsible for stable output, another for experiencing differences brought by floral and fruity notes, nutty cocoa or processing method. Only by putting coffee beans into actual drinks and judging can you know whether their flavor truly suits your daily life.
