Why do some coffees taste like wine?

When you encounter a coffee with distinct wine notes, you are often tasting the result of intentional post-harvest processing. While all coffee is technically a fruit, the natural process—where the coffee cherry is dried whole—allows the bean to absorb the sugars and acids from the fruit pulp during the drying phase. This fermentation process can produce intense, fruit-forward flavors that range from jammy berries to bright, vinous acidity.

Modern processing techniques have pushed these boundaries even further. Methods like anaerobic maceration involve fermenting the coffee in oxygen-free tanks, which can significantly increase the presence of carboxylic acids, such as lactic and acetic acid. These acids are the same compounds found in wine, and they contribute to that recognizable, tangy, and complex profile that specialty coffee drinkers often describe as 'winey.'

It is not just the processing that creates this effect; the variety of the coffee plant also plays a critical role. Certain varieties, such as Geisha or specific Ethiopian heirlooms, are genetically predisposed to express floral and fruit-forward characteristics that, when paired with careful processing, result in a cup that is remarkably similar to a glass of wine. The terroir also ensures that these flavors are grounded in the specific mineral content of the soil.

For the consumer, this means that 'winey' coffee is rarely an accident. It is the result of a producer carefully managing the fermentation environment to highlight specific sensory attributes. When you brew a coffee that reminds you of a Pinot Noir or a crisp white wine, you are experiencing the intersection of advanced agricultural science and traditional processing. In practice, these coffees are best enjoyed as pour-overs, where the clarity of the brew method allows these delicate, complex notes to shine without being masked by the heavy body of an immersion brew.
