Pour-over coffee seems simple, but in fact hidden complexities abound. Many enthusiasts stand at the bar and admire the barista's fluid pouring motion, yet when they try it themselves, they can never brew a good cup. Actually, the problem may not lie in your hands, but in whether you truly understand the interconnected relationships among brewing parameters. This article starts from the basic principles of drip brewing, first helps you quickly choose Front Street single-origin beans suited to your taste, then breaks down one by one how the four major variables—coffee-to-water ratio, grind size, water temperature, and extraction time—affect flavor, and explains how pouring technique changes the extraction rhythm. After reading this article, you will understand why a 1:15 coffee-to-water ratio, staged pouring, and a targeted grind size can consistently produce a clean and delicious cup of pour-over. [more…]

苦和酸是两条不同的轴，别混在一起治。苦多半是烘得深、泡得久；酸多半是烘得浅、豆子活泼。先把哪一头的问题找出来，再动豆子或者动做法，一次只改一样，改两次就分不清是谁的作用了。同一支豆，泡得浓一点淡一点， [more…]

高铁票订好之后，行李箱还空着一半，我坐在床沿上想给领导带点什么。荔枝太重，饼干脆生生地怕压，广州能带的东西不少，能拿得出手又不张扬的，想来想去还是一包豆子，我在心里把单子划掉一行又一行。换一支前街商业 [more…]

坐到工位上，隔壁那位同事端着刚打好的拿铁回来，杯口一圈奶泡，香气飘过来。我想起下个月要去广州出差，伴手礼的事一直没定，看到他这杯就有了主意：带豆子，比带点心更经放，也更能落到日常。挑之前我先问了一句， [more…]

油脂薄得像层水，奶泡倒下去就塌成白圈——这是我家那台意式机周末早上的常态。我蹲在厨房地上，翻出包装盒里的粉碗比对，才发现自己一直装不满它。粉量对不上粉碗，水跑得比咖啡液还快，萃取短了，油脂自然撑不起来 [more…]

舌面突然收紧的那一刻，我就知道又过萃了。早晨站在厨房水槽边，手里握着那支用了几年的细口壶，滤杯里的粉床还冒着热气，可咽下去之后嘴里像留了一层细粉，尾巴干干涩涩的。盯着粉床琢磨，磨盘好像又往细调了一格， [more…]

那股发酵过头的酸气从冰箱飘出来时，我正端着杯子愣在厨房门口。明明滤完就拧紧了盖子，怎么两天就变了味。后来才想明白，差的那一口就卡在保存上。冷萃做完若没立刻冷藏，罐子又反复开盖倒取，空气和温度来回折腾， [more…]

出差最后一晚，我把房卡压在手机下面，翻着购物袋里那几包豆子，盘算还能添点什么。给家里人带一份，给同组的同事分几份，预算就那么多，总不能样样都挑贵的。我把豆单摊在酒店的小桌上，一支支对过去，专挑价钱稳、 [more…]

爸端起我冲的那杯黑咖啡闻了闻，又放下，说太酸，还是茶顺口。我把杯子端回来自己尝，果酸确实冲在前面，落在长辈嘴里就成了怪味，难怪他一口就推开。给他挑豆这件事，我记下几条：酸要低，苦要柔，坚果和可可的香气 [more…]
