Wine Processing Method: A Controlled Fermentation Approach

The wine processing method, also known as the controlled fermentation method or lactic/acetic acid fermentation method, represents an innovative approach to coffee processing.

The Research Team

The experimental team is led by American Felipe Sardi and consists of biological scientists and ecologists.

Harvesting Standards

The specialized harvesting team is trained and strictly follows the specialty coffee bean harvesting requirements: unripe fruits are carefully selected.

Fermentation Methods

Acetic Acid Fermentation — Aerobic fermentation (produces cleaner, lively acidity with brighter quality, primarily citric acid)

Lactic Acid Fermentation — Anaerobic fermentation (results in rounder mouthfeel, slightly less clean than acetic fermentation but with higher body, primarily malic/tartaric acid)

Quality Control

Through controlled pH monitoring, the degree of fermentation is tracked to achieve predictable results with consistent quality across batches.

Visual Characteristics

Coffee beans processed with the wine method typically have a deeper color, with silver skin showing wine-red or brown-red tones attached to the green beans, making them highly recognizable.
