After coffee is planted and harvested, the next step is 'processing methods'. Previously, most processing methods were mainly natural and washed, followed by the rise of the 'honey processing method', which is further divided according to the proportion of pulp retained: black honey, red honey, yellow honey, and white honey, each with different flavor characteristics.

The 'wine aroma natural processing method' with extended fermentation time that approaches natural flavor, and the 'wine honey processing method' that adds enzymes similar to those used in red wine fermentation, approaching honey processing flavor.

Red wine processing method has once become a hot topic in the industry. In the process from coffee cherry to green coffee bean, 'fermentation' occurs to varying degrees, whether it's washed processing, honey processing, or natural processing—all undergo this chemical change. Different substances participating in fermentation (coffee skin, coffee pulp, coffee pectin, types of microorganisms, distribution of bacterial count), different fermentation environments (with or without water, aerobic or anaerobic, pH environment, etc.), and different drying processes (container materials, natural sun drying, drying equipment, number of turns, etc.) all contribute to different post-processing flavors and mouthfeel.

What is 'Anaerobic Fermentation Processing Method'?

Artificially harvested 100% ripe fruits undergo 'anaerobic fermentation method', with an average fermentation time of about 24 hours! This processing method has four key elements:

1. Shade System

Shade effectively blocks sunlight, allowing the pulp to generate more sugar, resulting in coffee with more sweetness and wonderful acidity.

2. Stainless Steel Containers (Most Important)

Coffee beans are placed in stainless steel containers for fermentation immediately after picking, abandoning traditional cement or other containers. These traditional containers absorb the flavor of the coffee beans rather than retaining more coffee flavor in the coffee pulp, while stainless steel containers allow the coffee flavor to be cleaner.

3. Carbon Dioxide

The coffee beans placed in stainless steel containers are sealed and pressurized with carbon dioxide, ensuring no air remains in the container. This guarantees that all coffee flavors and aromas are retained in the coffee, making the original coffee flavor more distinctly preserved.

4. Controlled Temperature

These coffee beans are all processed in temperature-controlled environments, allowing the coffee beans to have consistent flavors, whereas traditional processing methods make it difficult to maintain consistent flavors for each batch of processed beans.

FrontStreet Coffee's [Panama Hartmann] uses this processing method. The red wine processing method gives these beans a rich fermented wine aroma that is truly impressive!
