FrontStreet Coffee - Introduction to Costa Rican Coffee

Coffee needs elegant and charming acidity to achieve higher scores. This includes various organic acids naturally present in coffee (chlorogenic acid, malic acid, citric acid, tartaric acid, etc.). At the same time, numerous fruit-forward alcohol, ester, aldehyde, and ketone compounds all contribute to coffee's special fruit-flavored acidity. Therefore, coffee或多或少 will contain substances with acidic tastes, as it ultimately comes from a berry fruit.

What Creates Coffee's Acidity?

Acidity is one of the most important aspects of coffee tasting. When describing coffee flavors, acidity typically refers to a lively, fresh, and crisp sensation, similar to the mouthfeel of wine, with a strong and exciting texture, sometimes also referred to as brightness.

Without acidity, coffee becomes lifeless, tasting hollow and bland. Fresh coffee beans contain various organic chemical compounds that constitute coffee's unique flavor profile. One of these is chlorogenic acid, which gradually decomposes during the roasting process, producing numerous aromatic substances.

The Republic of Costa Rica (Spanish: La República de Costa Rica), commonly referred to as "Costa Rica," is a presidential republic located in Latin America, bordering Nicaragua to the north and Panama to the south.

Coffee beans produced in the high-altitude regions of Costa Rica are world-renowned, being rich, mild in flavor, yet extremely acidic. The coffee beans here are all carefully processed, which is why they achieve such high quality. Costa Rica is located south of the capital San José in the Tarrazú region, and it is the country's most valued coffee.

Costa Rican coffee beans are full-bodied, with ideal acidity and unique, intense aroma. Costa Rica's coffee industry was originally controlled by the Costa Rican Coffee Institute (Instituto del Café de Costa Rica, abbreviated ICAFE), but has now been taken over by the Coffee Office (Oficina del Café). Among exported coffees, those considered substandard are colored with blue plant dye before being returned for domestic sale. Coffee consumed domestically (whether dyed blue or not) accounts for approximately 10% of total production, with local per capita coffee consumption being twice that of Italy or the United States.
