Wine Processed Coffee Beans for Espresso and Latte Art

If you’ve ever wondered why some espresso shots taste like dark cherry reduction or why your milk drink carries hints of red wine without a drop being added, the answer might lie in how the beans were processed—not just where they were grown. One experimental method is turning heads for delivering wine-like complexity in the cup.

The key? A 20.6-hour anaerobic fermentation after removing the coffee cherry’s skin and pulp, followed by 10 days of sun drying on raised beds. This wine processing method isn’t just a gimmick—it creates distinct flavor profiles sought after by baristas and coffee enthusiasts alike.

What Is Wine Processed Coffee?

Wine processing, also called anaerobic fermentation, involves removing the coffee fruit’s outer skin and pulp, then fermenting the beans in a water-free, sealed environment for a set time—here, exactly 20.6 hours. This controlled fermentation mimics conditions similar to winemaking, allowing the beans to absorb unique aromatic compounds. After fermentation, the beans are spread on high, ventilated drying racks (raised beds) and sun dried over 10 days. The result is a coffee with wine-like aromatics and layered fruitiness.

Why This Process Creates Unique Flavors

By removing the cherry’s skin and pulp and fermenting the beans without water in an oxygen-free environment for 20.6 hours, this method concentrates and transforms the beans’ flavor precursors. The extended fermentation period allows for the development of complex, wine-associated esters and acids. Following this, the slow 10-day sun drying on raised beds helps preserve those volatile compounds while developing sweetness and body. The combination leads to tasting notes often associated with red wine—dark cherries, berries, and subtle tannic structure—alongside traditional coffee sweetness and acidity.

How to Use Wine Processed Beans in Espresso and Milk Drinks

This style of processed coffee shines in espresso-based drinks. Its inherent sweetness, body, and wine-like fruit character make it ideal for lattes and cappuccinos, where it contributes to smooth mouthfeel and complex crema. Baristas report stable latte art due to the coffee’s balanced texture and crema retention. For espresso, expect a syrupy shot with notes reminiscent of dark fruit and a velvety finish. The process also complements blends designed for milk drinks, enhancing both flavor depth and visual appeal in drinks featuring latte art.

How long is the fermentation for wine processed coffee?

The fermentation lasts precisely 20.6 hours in an anaerobic (oxygen-free), water-free environment before the beans are moved to raised beds for drying.

How are the beans dried after fermentation?

After 20.6 hours of anaerobic fermentation, the beans are dried on high, ventilated raised beds (sun drying) for 10 days, which helps develop sweetness and preserve fermentation-derived flavors.
