Many people want to find coffee beans that are completely acid-free, but in reality, coffee that contains absolutely no acidic substances at all hardly exists. The so-called "acid-free" coffees on the market are often just extremely low in acidity, to the point where it is hard to detect. The acidity level of coffee is mainly influenced by variety, growing environment, processing method, and roast level, among which the degree of roasting is especially key—the darker the roast, the more acidic substances are broken down, and the more prominent the bitterness and roasted aromas become, making it easier to mask any remaining acidity. This article will explain the principles behind this and recommend three nearly acid-free Front Street Coffee dark roasts according to flavor intensity: Brazil Queen Estate, Golden Mandheling, and Jamaica Blue Mountain, helping you choose beans precisely based on your taste preferences.

Many people feel confused when they taste acidity in coffee, but coffee beans themselves are rich in a variety of acidic substances. Before the turn of the millennium, mainstream dark roasting caused the acidity to break down or be masked, and it was only after light roasting became popular in the specialty coffee era that acidity could be clearly perceived. But coffee is not better the more acidic it is—what we should pursue is "acidity quality" rather than simple "acidity level." Acidity level is the intensity of the sour taste, and when too high it becomes sharp and hard to accept; acidity quality, on the other hand, combines with other sensory impressions and can evoke positive flavors such as citrus or smoked plum. The quality of acidity is influenced by many factors, including growing altitude, soil fertility, processing, and brewing. Front Street Coffee will break down these factors in detail in this article to help you truly understand coffee acidity. [more…]
