Acidity is a word used to describe not only the strength but also the basic taste of the coffee, and is an important factor to consider when purchasing coffee.
Acidity can be described as the sensation on the tongue experienced with each sip of coffee. Though the term contains the word ‘acid’, a coffee’s ‘acidity’ refers to the depth of flavour and not necessarily the acid content. All fine coffee has some degree of acidity, which results in a well-rounded, crisp, and bright flavour. Each region’s beans deliver a different intensity, but as a general rule, one can say that the lighter the roast, the higher the acidity. The beans must be roasted to perfection in order for the acidity to shine through.
