在home-barista看到这篇" Coffee Roasting Defects Pictorial",见猎心喜,就把它给留存了。 虽说咖啡要喝了才准,但,用看的也可以找出不少问题,在逻辑上并没有冲突。 源自于"Home Roasting Competition"的讨论(对象是水洗豆) Quaker: 未熟豆

Center line charring: 中心线烧焦,脱水至一爆前之火力过强造成

Under roasting: 烘焙不足,刚进一爆不久,豆子的平面和半圆型面成90度,用于杯测OK,不适宜日常饮用

More dinkable roast: 一爆完成,中心线两侧微鼓起,豆体有较好的扩展

Bean expansion after 1st crack: 完成一爆后的豆体膨胀裂开,中心线未烧焦,可以明显看到缝内的银皮

附注:中心线在二爆前会变黑,这可以作为一爆结束与二爆前判断的一个依据
