Exploring Colombia El Vergel Estate Yellow Bourbon

In Melbourne's vibrant specialty coffee scene, filter brewing methods have gained remarkable popularity for their ability to showcase the intricate flavour profiles of single origin coffees. At Manta Ray Coffee Roasters, we take pride in our carefully curated selection of exceptional filter coffees, each telling a unique story of origin, variety, and processing. This article delves into the captivating world of pour-over brewing through the lens of one of our most distinctive offerings: Colombia El Vergel Estate Yellow Bourbon Anaerobic Natural.

The Filter Coffee Renaissance

Filter brewing represents coffee in its purest expression—a transparent brewing method that reveals the true character of each bean without the intensity of espresso extraction. The growing appreciation for filter coffee reflects a maturing coffee culture that values subtlety, complexity, and the distinctive terroir of single origin offerings.

Why Filter Coffee Matters

Unlike espresso and milk-based beverages that often highlight specific flavour components, filter brewing unveils the complete spectrum of a coffee's character:

• Clarity of Flavour: Clean cup profile allows subtle notes to shine through
• Aromatic Complexity: Lower brewing temperature and pressure preserve volatile compounds
• Evolving Experience: As the coffee cools, different flavour notes emerge and develop
• Origin Transparency: The true expression of terroir, processing, and varietal characteristics

Spotlight on Colombia El Vergel Estate Yellow Bourbon

The El Vergel Story

The journey of this remarkable coffee begins in 1995, when the Bayter family embarked on an agricultural venture at El Vergel farm in Colombia's Tolima region. Initially focused on avocado cultivation, their path took an unexpected turn when market conditions forced them to diversify in 2006. They planted their first coffee trees—varieties like Catimore, Red Caturra, and Yellow Caturra—unknowingly setting the stage for coffee excellence.

The true transformation came in 2016 when, guided by coffee expert Miguel Jimenez, they embraced specialty coffee varieties. By 2018, El Vergel had evolved into a hub of coffee innovation, particularly in experimental fermentation techniques. Today, under the visionary leadership of Martha Montenegro alongside partners Elias and Shady, El Vergel Estate represents the perfect harmony of tradition, community, and cutting-edge coffee science.

The Yellow Bourbon Variety

Yellow Bourbon stands as one of coffee's noble varieties—a natural mutation of the classic Bourbon cultivar, distinguished by its yellow cherries when ripe rather than the typical red. This variety offers:

• Elevated Sweetness: Naturally higher sugar content than many other varieties
• Complex Acidity: Bright yet balanced, with multi-layered fruit notes
• Distinctive Mouthfeel: Silky texture that carries flavour beautifully
• Exceptional Potential: Responds remarkably to advanced processing techniques

Anaerobic Natural Processing: Crafting Complexity

What truly sets this coffee apart is its meticulous processing method. The anaerobic natural process represents both ancient wisdom and modern innovation:

1. 48-Hour Anaerobic Fermentation: Freshly harvested cherries are placed in sealed tanks without oxygen, allowing controlled fermentation that develops precise fruit characteristics and sweetness
2. Eight-Day Mechanical Silo Drying: After fermentation, the cherries dry slowly in specialised silos, allowing for even moisture reduction while preserving developed flavours
3. 35-Day Resting Period: Following drying, the beans rest in Grain Pro bags, allowing flavours to stabilise and integrate before the final milling process

This painstaking approach results in a coffee with extraordinary complexity and a distinct flavour profile impossible to achieve through conventional processing.

Tasting Notes: A Sensory Journey

When brewed as a filter coffee, Colombia El Vergel Estate Yellow Bourbon Anaerobic Natural presents a captivating sensory experience:

Aroma

The first impression reveals intoxicating notes of overripe strawberries, candied citrus, and sweet stonefruit—an aromatic preview of the cup to come.

Flavour Development

• First Impressions: Vibrant overripe strawberry notes dominate, creating an immediately juicy and fruit-forward experience
• Mid-Palate: Candied tangerine peel emerges, offering bright citrus complexity and a sophisticated sweetness
• Finish: Luscious yellow peach notes reminiscent of canned peaches provide a comforting, sweet roundness

Structure and Mouthfeel

The cup presents with a silky, medium body that carries flavours beautifully across the palate. A refined, wine-like acidity provides structure without overwhelming, while the sweetness offers perfect counterbalance—reminiscent of candied fruit and natural honey.

Brewing Guide: Unlocking El Vergel's Potential

To fully appreciate the exceptional qualities of this coffee, we recommend precise brewing parameters:

Recommended Pour-Over Specifications

• Brewing Ratio: 1:16 (15g coffee to 240g water)
• Grind Size: Medium-fine (slightly finer than typical filter settings)
• Water Temperature: 92-94°C (slightly lower than boiling to protect delicate flavour compounds)
• Total Brew Time: 2:45-3:15 minutes
• Filter Type: Paper filter (to highlight clarity and brightness)

Step-by-Step Pour-Over Method

1. Preparation: Rinse filter paper thoroughly with hot water to remove paper taste and preheat equipment
2. Bloom Phase: Pour 45g water (three times coffee weight) and gently stir to ensure even saturation; allow to bloom for 45 seconds
3. First Pour: Slowly add water in concentric circles until reaching 150g total, avoiding the edges of the filter
4. Second Pour: After draining slightly, continue pouring until reaching 240g total water weight
5. Agitation: Give the brewer a gentle swirl to flatten the coffee bed for even extraction
6. Drawdown: Allow all water to drain through; total brew time should fall between 2:45-3:15

Temperature Journey

For the full experience, we recommend:

• Initial Tasting: Begin at around 65°C when aromatic intensity peaks
• Mid-Temperature Tasting: Experience how flavours evolve as the cup cools to 45-50°C
• Cool Temperature Appreciation: Note how sweetness often amplifies at lower temperatures (35-40°C)

The Filter Coffee Experience: Beyond the Cup

What makes filter coffee particularly special is how it invites mindfulness. The slower brewing process and evolving flavours encourage a more contemplative coffee experience—one that rewards patience and attention.

Creating Your Filter Ritual

Consider developing a personal filter coffee ritual:

• Dedicated Time: Set aside 15-20 minutes to fully appreciate the brewing and tasting experience
• Sensory Focus: Note how aromas develop from dry grounds to wet brewing to final cup
• Flavour Evolution: Return to the cup as it cools to discover how flavours transform
• Comparative Tasting: Try different brewing parameters to find your preferred expression
