What is the "new" specialty coffee trend?
The 'new' specialty coffee trend is the shift toward experimental processing, such as anaerobic fermentation, co-fermentation, and the use of wine yeasts. These techniques allow producers to manipulate the flavor profile of the coffee, creating intense, fruit-forward, and unconventional notes that push the boundaries of traditional coffee flavor and appeal to a new generation of enthusiasts.
For decades, the specialty coffee industry focused primarily on the 'terroir'—the idea that the flavor of the coffee was dictated almost entirely by the farm's altitude, soil, and variety. While these factors remain essential, the current trend is a move toward 'process-driven' flavor. Producers are now acting as scientists, using controlled fermentation environments to intentionally influence the final cup profile.
Techniques like anaerobic fermentation—where coffee cherries are fermented in sealed, oxygen-free tanks—have become increasingly common. By controlling the environment, producers can encourage specific microbial activity, leading to coffees with heightened sweetness, acidity, and unique flavor notes like tropical fruit, bubblegum, or spice. This is often taken a step further with co-fermentation, where fruits, spices, or specific yeast strains are added to the fermentation tank to impart specific characteristics to the beans.
This trend is driven by a desire for innovation and the need for farmers to differentiate their products in a crowded global market. For roasters, these coffees offer a new palette of flavors that can be marketed as 'experimental' or 'limited edition,' attracting customers who are looking for something beyond the traditional chocolatey or nutty profiles. It represents a shift in the industry where the producer's role is seen as an active creator of flavor rather than just a harvester of raw material.
However, this trend is not without its critics. Some purists argue that these intense processing methods can mask the true character of the coffee variety or the origin. Despite this, the popularity of these coffees continues to grow, particularly among younger consumers and specialty coffee shops that prioritize novelty and sensory exploration. In practice, this means that when you see terms like 'anaerobic' or 'yeast-inoculated' on a coffee bag, you can expect a cup that is significantly more intense and unconventional than what you might be used to.
