很酸的咖啡是好咖啡吗 我家的咖啡粉是散装的，没牌子，冲出来很酸。[最佳]认识酸溜溜的咖啡 「小姐,为何今天的早餐咖啡喝来酸酸的,我不喜欢,能不能给我一杯不酸的咖啡?」此问题一直困扰著咖啡业者. 一般人误以为咖啡不新鲜就会有酸味,acidic coffee不是好货.这真是天大的抹黑与误解!其实,coffee本身就是acid性饮料,coffee acid not.

Is a more acidic cup of coffee better or worse？ [Best]Coffee has acidity which is normal; how can that be bad～`Acidity will affect the quality of the bean and variety; generally speaking, beans roasted less have more acidity while beans roasted deeper have less acidity.

Should there be some acidity in every cup of coffee? When drinking clear-roasted beans（清烘焙）， one always feels a slight sourness； friends say that one big characteristic of clear-roasting is its sour-bitter taste. [Best]Pure Coffee has some natural acidity.
