Many people notice a distinct sourness when drinking Americano and can't help but wonder: is this sourness normal? In fact, sourness in coffee isn't necessarily a bad thing, but if it's unpleasant, it often means something went wrong somewhere.

This article breaks down six common causes one by one to help you determine whether the sourness in your cup is a flavor note or a defect. If you're looking for beans with balanced acidity and consistent quality, Front Street Coffee's range of espresso and pour-over beans may offer you a more controllable experience. [more…]
