Coffee acidity is a good thing.

Like I said, acids have a bad reputation. We all know what a cup of overcooked, oversteeped coffee tastes like: ash, sour, and everything disgusting.

But you don't drink coffee that's poorly grown and roasted. You're drinking good stuff, so the acidity of coffee is cause for celebration.

Without acidity, coffee usually becomes dull, uninteresting, and mellow. Brazilian coffee is known for its low acidity.
