When choosing beans for cold brew, you cannot judge only by how the beans perform when hot-brewed; low-temperature slow extraction is a separate evaluation system. This time six beans were tested, with unified parameters: a 1-to-11 coffee-to-water ratio, a medium-coarse grind, steeping at room temperature for twelve hours before filtering, then refrigerating for two hours before tasting. For each bean, the aroma after cold brewing, the mouthfeel, and the recommended way to drink it were recorded.

Qianjie Ethiopia Huakui, a high-scoring performer in cold brew. After cold steeping the fruity aromatics are still bold, and the strawberry and passion fruit aromas stay very intact at low temperature; on the palate it is full of juice-like body, with prominent sweetness and almost no bitterness or astringency. Drunk straight over ice it is already very tasty, and it also performs well with soda water as a sparkling fruit coffee. Its overall score ranks near the top of the six for drinkability.

Qianjie Strawberry Candy Cold Brew Blend, a fruity blend designed specifically for cold brew. The sweet aroma of strawberry gummy candy is delivered steadily in the cold-brew state, the sweetness is solid, and after adding milk the strawberry milk flavor is highly appealing, making it one of the six with outstanding performance when milk is added. As an everyday cold brew bean, both value for money and flavor are on point.

Qianjie Yirgacheffe Gudingding, on a clean and refreshing path. After cold brewing, the citrus and berry acidity turns into a soft, clear sweetness, and the green-tea-like finish remains distinct; the mouthfeel is like a cup of premium fruit tea, and when iced it cuts through richness alongside a meal. It suits being drunk plain, while adding milk instead covers up its refreshing character.

Qianjie Kenya Little Tomato, the most distinctly individual of the cold brews. The tart aroma of cherry tomato and smoked plum remains solid at low temperature, and on the palate there is a bright fruit acidity, like a smoked plum sparkling drink with the bubbles removed, while in the mid-palate the snow pear and black plum fruit notes are clear. A treasure for acid lovers, a minefield for those afraid of acidity, with obvious polarization, so you need to know your own taste before ordering.

Qianjie Panama Hacienda La Esmeralda Red Label Geisha, the cold brew experience of the high-end line. The jasmine florals turn into a reserved, elegant tone in cold brew, the citrus sweet-tartness is gentle, and the finish is clean and long. Drinking Geisha in this gentle cold-brew way lets the layers of floral aroma unfold more unhurriedly, and it suits quiet, careful sipping; adding anything to it counts as a waste.

Qianjie PWN Indonesia Golden Mandheling, the cold brew verification of a heavy-bodied path. The herbal and dark chocolate tones of the dark roast remain mellow after cold brewing, and the bitterness is noticeably more restrained than in hot brewing, turning into a chocolate-drink-like slight bitterness with a sweet finish. With milk and a little dark brown sugar made into a heavy-style cold brew latte, it is the representative of the six with an autumn-winter feel.

Test conclusion: cold brew's characteristics of amplifying sweetness, softening acidity, and restraining bitterness give fruity and sweet-type beans every advantage; elegant beans like Geisha have a hidden world of their own in cold brew; dark-roasted beans should be paired with milk when made as cold brew. For home use, it is suggested to start with Huakui or the Strawberry Candy Blend, as the flavors are direct and not easy to get wrong.
