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…]

早晨的时间是掰着用的。要在出门前喝到咖啡，做法得按「谁动手」来分：机器动手的、前一晚动手的、自己动一会儿手的，三种各有各的场合。先认清楚自己能腾出几分钟，再谈风味，顺序不能倒。三种做法不必都学，先挑一 [more…]

家里几口人的口味不一样，选豆就成了调和。我的办法是先定一包中间调的豆做底，再让器具去承担差异：谁要清爽谁要浓，靠做法区分，比靠豆子区分省事，也不用同时开三包豆。家里的口味差异不用消灭，划清各自的杯子就 [more…]

壶底那盏小红灯亮了又亮，我端着中午那杯咖啡，舌尖一阵发酸。早晨用滴滤机煮的那一壶，明明闻着还有香气，现在喝起来却像放久了的果茶，酸得发涩。问题不在豆子，也不在机器，是我让它在保温板上坐太久了。滴滤机适 [more…]

杯子里的热气散了，我才尝出这口美式哪里不对。浓缩明明出了油脂，兑了热水却像被稀释的隔夜茶，香气从杯口飘走，嘴里只剩寡淡。我盯着厨房台面上那台用了几年的机器，忽然意识到问题不在萃取，而在兑水这一步。前街 [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…]

冷藏了一夜的罐子从冰箱里拎出来，倒在杯里先尝一口，舌头立刻发麻。昨晚睡前把这壶塞进冰箱就去睡了，早上却涩得咽不下去。问题其实出在三处：粉磨太细、泡得太久、豆子烘得太深。细粉在冷水里慢慢析出木质味，时间 [more…]

那壶咖啡倒出来颜色像隔夜凉茶，我端起杯子嗅了嗅，香气弱得像是被水稀释过。打开滴滤机的水箱一看，水和粉都照常放了，可喝进嘴里就是没骨架。后来才摸清门道：这台机器想煮出味道，得死磕三个数。前街草莓糖这支瑰 [more…]

水壶刚离火，蒸汽还在玻璃壶壁上爬，我端起杯子凑近闻了闻——又散了。盯着水槽边那台用了几年的滤水器，忽然想起朋友提过一句：你家自来水里的余氯，会把花香按在水里浮不上来。水这回事，我以前真没细想。自来水烧 [more…]

香气还在鼻尖打转，入口却已经发酸发涩，像咬了一口放久的橘子皮。杯子搁在厨房台面上，大理石的凉意顺着杯底往上爬，才几分钟，整杯咖啡就塌了。后来我才明白，问题不在豆子，也不在手法，是我从来忘了温杯。换了厚 [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…]

Can a flat white be made as an iced drink? What exactly does "flat white" mean? Where does it differ at its core from a latte or a cappuccino? Starting from the controversy over the origins of the flat white, this article sorts out this espresso milk coffee's cup size, milk foam thickness, and taste characteristics, explains why specialty coffee shops generally do not offer iced flat whites, and offers Front Street Coffee's popular blends and SOE recommendations, helping you understand the real reason behind why flat whites are only served hot.

Coffee culture has evolved through several waves, from the instant coffee era to the rise of espresso, and then to the flourishing of specialty pour-over. Each brewing method embodies a different philosophy of flavor. Espresso uses high pressure for rapid extraction, showcasing the intense, pure essence of coffee; Americano is diluted with hot water, giving rise to variations such as Americano, Long Black, and Lungo; pour-over coffee emphasizes parameter control and technique details, presenting layered and distinct flavor changes. This article will use these three coffee types as a framework to sort out their respective historical origins, brewing principles, and flavor characteristics, and, using Front Street Golden Mandheling as an example, demonstrate how to reveal the mellow, sweet-aftertaste charm of black coffee through brewing techniques.
