What makes the Colombia wine coffee process different?
Red wine processing is a controlled fermentation method developed in Colombia that shapes acidity and sweetness by managing the fermentation environment rather than leaving it to chance. Acetic acid fermentation is aerobic and produces higher cleanliness with lively, citric-style acidity, while lactic acid fermentation is anaerobic and gives a rounder body with malic and tartaric tones and slightly lower cleanliness.
The work was led by American researcher Felipe Sardi with biological scientists and ecologists, and it relies on strict picking standards: underripe cherries under 2 percent, defective beans under 3 percent, floating beans under 5 percent. Front Street Coffee's Colombia JOAQUIN red wine process bean shows the sweeter, layered result of this coffee process and works well as a pour-over.
Red wine processing is an innovative green coffee processing technique originating from Colombia that precisely shapes the acidity and sweetness of coffee through manually controlled fermentation environments. This article provides a detailed overview of the historical background, scientific principles, and specific operational procedures of this processing method, and further introduces the origin information, flavor characteristics, and pour-over recommendations for Front Street Coffee's Colombia JOAQUIN Red Wine Process coffee. Whether you want to understand the difference between acetic acid fermentation and lactic acid fermentation, or are looking for a bean with prominent sweetness and elegant acidity, this content can provide practical reference.
Colombia Red Wine Processing
Among the many coffee-producing regions around the world, cases of successfully putting wine-like processing methods into practical application are extremely rare. After lengthy repeated trials, the R&D team finally achieved effective control over the acidity structure in this processing method. With a process similar to wine fermentation, the sweetness of the coffee beans is significantly enhanced, and the cleanliness and layered, elegant acidity are also greatly improved. This fermentation path has led to noticeable improvements in both the quality and distinctiveness of the final product.
Red wine processing is also known as controlled fermentation, or lactic/acetic acid fermentation.
The experimental team was led by American Felipe Sardi, with members including biological scientists and ecologists, who introduced technologies such as solar energy into the green bean cultivation and processing stages.
The professional hand-picking team, after systematic training, strictly follows specialty coffee harvesting standards: underripe cherries below 2%, defective beans below 3%, and floating beans below 5%.
Acetic acid fermentation — aerobic fermentation
Lactic acid fermentation — anaerobic fermentation
Expected flavors are as follows:
Acetic acid fermentation: higher cleanliness, lively and bright acidity, with citric acid characteristics
Lactic acid fermentation: rounder mouthfeel, slightly lower cleanliness than acetic acid fermentation, but with more prominent body, showing malic acid/tartaric acid tones
Prior to this, processing plants generally relied on handcrafted experience passed down through generations, such as chewing coffee beans to judge fermentation progress. This method was difficult to control consistently, and the results varied widely.
Controlled fermentation, on the other hand, monitors pH levels to gauge the degree of fermentation, thereby achieving predictable results and ensuring consistency from batch to batch.

Grind size is based on the Yangjia Little Flying Horse grinder as reference; the above values are for reference only. Please adjust flexibly according to actual conditions and personal preference.
Roasting notes:
This Front Street Colombia JOAQUIN Red Wine Process coffee bean uses a unique red wine processing technique: after removing the skin and pulp and washing clean, the beans are placed in a waterless fermentation tank to ferment for 20.6 hours, then placed on raised drying beds for 10 days of sun drying to complete. This processing method gives the coffee a special flavor that is well worth tasting.
