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…]

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…]

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…]

日历上圈着朋友生日，正好落在我从广州回来那周。他家厨房角落摆着一排手冲器具，滤杯擦得发亮，手冲壶的壶嘴细长。上回在他家喝的那杯，酸甜干净，我到现在还记得。送礼送到这份上，摆件他看不上，豆子才对他的胃口 [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…]

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…]

选豆这件事，我习惯让客人先回答三个问题：早上有多少时间、台面能放多大、愿不愿意洗。三个答案合起来，器具就定了，豆子的方向也跟着清楚。反过来先买豆，往往要退货，或者放进柜子里积灰。这不是绕弯子，是把钱花 [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…]
