What is "funk" in specialty coffee?

In the past, coffee flavor was largely defined by origin and variety. Today, we are in the era of the 'process-driven' flavor, where the way a coffee is fermented can be just as influential as the soil it was grown in. When you hear a barista describe a coffee as 'funky,' they are usually referring to the results of controlled, experimental fermentation techniques that produce bold, non-traditional flavors.

'Funk' is not a technical term, but rather a shorthand for the complex, often wild flavors that emerge from anaerobic fermentation, carbonic maceration, or the use of specific yeast inoculations. During these processes, producers manipulate the environment—often by removing oxygen or adding specific bacteria—to encourage the development of unique acids and esters. The result can be a cup that tastes like fermented pineapple, red wine, or even balsamic vinegar. It is a departure from the clean, predictable profiles of traditional washed coffees.

For many, this 'funk' is the pinnacle of specialty coffee innovation. It represents a level of control and creativity that allows producers to highlight the potential of their harvest in entirely new ways. However, it is also a polarizing subject. Some drinkers find these flavors exciting and refreshing, while others feel they mask the inherent character of the coffee bean. It is a reminder that coffee is an agricultural product that can be transformed through human intervention.

In practice, if you are curious about 'funky' coffees, look for labels that mention 'anaerobic,' 'carbonic maceration,' or 'experimental process.' These coffees are often best enjoyed as a pour-over, where the clarity of the brew allows the complex, fermented notes to shine. Be prepared for a different experience; these coffees are rarely subtle. They are designed to challenge your palate and offer a glimpse into the future of coffee processing, where the line between coffee and fine wine continues to blur.
