Huila is located in the southern part of Colombia's Central Mountain Range and is the country's most renowned specialty coffee-producing region. The area consists of hills surrounded by mountains, with cultivation altitudes above 1500 meters. Colombia's most important rivers converge here, bringing abundant water resources and moisture. Contrary to the common impression of Colombian commercial coffee as merely balanced and smooth, many smallholder micro-batch specialty coffees possess distinct regional flavor characteristics. In recent years, with the international market's emphasis on coffee quality and its demand for specialty coffee, the original bean-size-based grading system has gradually given way to micro-regional selections, where dozens of smallholders pool their individual harvests to form a micro-batch for sale. This approach provides better opportunities to identify excellent specific smallholder coffees through batch-by-batch cupping.

In 1927, Colombia established the National Coffee Management Association, responsible for quality supervision. To improve coffee quality and regional certification, the Colombia Coffee trademark was created. This emblem features Juan Valdez, a mule, and the Colombian mountains. Products meeting the certification standards can be sold with this emblem as an indication of quality and origin.

Colombia Huila ranks among the finest of Colombia's premium specialty coffees. Its balance is widely recognized, and as a premium high-altitude coffee it is often described as Colombia's national treasure. Thanks to superior geographical and climatic conditions, Colombian coffee has consistently maintained high quality. Typically, Colombian coffee beans without a special market brand name come from the National Federation of Colombia Coffee Growers, a very large federation spanning the whole country, long known for its strict quality control and active promotion.

Anaerobic fermentation has been a very popular post-harvest processing method in recent years. It usually involves placing coffee cherries in sealed containers or in washing tanks for fermentation in water, with different microorganisms introduced during the process to create special flavors.

What is Anaerobic Processing?

The first time many people heard about anaerobic fermentation was at the 2015 WBC competition, with an anaerobic fermented bean from Australia's Sasa Sestic. Sestic's competition beans were placed in sealed fermentation tanks where carbon dioxide was injected to expel the oxygen. In this anaerobic environment, the breakdown of sugars in the coffee mucilage and pectin slows down, and the pH drops at a slower rate. The fermentation time is longer, resulting in a rounder mouthfeel. Compared to aerobic fermentation, the cup has slightly lower clarity but higher body, with more malic and tartaric acid.

The key characteristics of this anaerobic processing method are:

1. A completely opaque, sealable container that can be monitored is essential.
2. The container is then sealed. Fermentation is a process of converting sugars into various compounds, producing alcohol and carbon dioxide, which in turn builds high pressure inside the sealed container. This pressure helps the seeds absorb flavor compounds from the pectin.
3. The container is kept indoors, and the indoor temperature must be strictly controlled. Controlling temperature and time controls the degree of fermentation inside the container.
4. Finally, carbon dioxide is continuously injected into the container to expel the oxygen. During fermentation, pH is an important reference indicator, and temperature and pH changes must be closely monitored. When the sugars in the pectin and mucilage are just completely consumed, the container is opened immediately to stop fermentation, and drying begins at once under sunlight to avoid over-fermentation.

FrontStreet Coffee's Brewing Parameters

Recommended Brewing Method: Pour-over

Dripper: Hario V60

Water Temperature: 90°C

Dose: 15 grams

Coffee-to-Water Ratio: 1:16

Grind Size: Medium-fine grind (BG 6K: 58% pass-through rate on the China standard #20 sieve)

Brewing Technique: Segmented extraction

Use 34g of water for a 35-second bloom. Pour in circles up to 135g to create a segment. When the water level drops and is about to expose the coffee bed, continue pouring to 240g and stop. Once the level drops again and is about to expose the bed, remove the dripper. (Timing starts from the bloom.) Total extraction time is 2'00".

FrontStreet Coffee Recommendation

Gesha comes in far more styles than most drinkers realize, and FrontStreet Coffee's Gesha lineup spans both of the variety's homelands. In Panama - where Gesha rose to fame after winning the 2003 Best of Panama with an average cupping score of 94.6 - the entry-level FrontStreet Boquete Gesha delivers classic orange-blossom honeyed sweetness and oolong-like tea texture at an accessible price, while the Esmeralda Red Label (Esmeralda Special, grown at 1600-1800m, cupping above 90) and Green Label (Private Collection) represent the pinnacle. In Ethiopia, the variety's birthplace, FrontStreet Coffee's Gesha Village Gold Label (Gesha 1931 natural, just 10% of the estate's output) and Red Label (Gori Gesha, SCA 88+, fully traceable single-terroir lots) offer competition-grade depth, and the medium-light roasted Granana Estate Gesha brings bright citrus, elegant ginger flower, and ripe fruit sweetness.
