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 clear flavors after milk is added. First decide whether milk will be added to the cup, then choose the style of beans; that 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 often 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 "high-value Yirgacheffe coffee bean recommendations," you can first break the choice into several parts: flavor preference, commonly used equipment, drinking temperature and daily frequency of use. When choosing for black coffee versus milk coffee, it is worth first deciding which one you care about more, then using the other conditions to narrow it down. This preserves individuality and also lets the beans show clear characteristics in actual brewing.

Qianjie Grana Estate Geisha has notes of orange blossom, guava, apricot and strawberry jam, with rich natural-process flavors, and is suitable for pour-over to observe its layers.

Qianjie Colombia Sidra has passion fruit, blueberry, grape and apricot notes, with obvious juicy character, and can show aroma in iced pour-over, cold drip and SOE.

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 kept 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 coffee and iced, milk-added versions may also perform differently; 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 drinking where stable output is the goal. If several people at home drink coffee, first choose a balanced bean as a base, then add single-origin experiments 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. 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, your drinking habits or your taste change, you can also divide the three beans into daily and exploratory categories: one for stable output, and another to experience differences brought by floral and fruity notes, nutty-cocoa notes or processing methods. Only by putting coffee beans into actual drinks can you know whether their flavor truly suits your daily life.
