What are the Flavor Differences Between Yellow Honey, Red Honey, and Black Honey Processing in Costa Rica?

Introduction to Costa Rican Coffee

Coffee cultivation in Costa Rica began in 1779 with introductions from Cuba, with the first exports only occurring in 1820. Today, there are approximately 32,000 coffee farmers, each cultivating an average area of less than one hectare (10,000 square meters). Costa Rica has a population of 4.1 million (as of 2006), with coffee cultivation covering 82,500 hectares. The annual production reaches 1.7 million bags (60kg per bag), with domestic consumption at 380,000 bags. The average per capita annual consumption is 5.5kg, higher than Japan's 4kg and significantly more than Taiwan's current average of just over 1kg.

Costa Rica's Coffee Heritage

Costa Rica was the first country in Central America to introduce coffee cultivation, boasting a long history and a comprehensive system from production to sales. Located in the Central American isthmus, the country features numerous volcanoes and enjoys natural advantages of abundant sunshine and fertile land. The climate is moderated by Pacific and Atlantic ocean currents and sea breezes, producing coffee with distinctive local microclimate characteristics. In both quality and quantity, Costa Rican coffee has consistently received global recognition and is ranked among the world's high-quality coffees.

Many towering volcanoes in the country reach altitudes of 2,000 meters, allowing coffee cherries to grow slowly in fertile volcanic ash soil and high-altitude cool environments, nurturing coffee beans with complete and rich flavors.

Coffee Growing Regions

Coffee cultivation in Costa Rica began two hundred years ago, with the earliest plantings located on the slopes of Poas and Barva volcanoes—today known as the Central Valley region. After years of development, Costa Rica now has eight main growing regions: Guanacastes, West Valley, Central Valley, Turrialba, Orosi, Tres Rios, Tarrazu, and Brunca.

According to ICO statistics, Costa Rica produces approximately 1.6 million bags of Arabica coffee annually. While production volume is lower than other Central American countries like Guatemala and Honduras, its quality and price are significantly higher.

Climate and Processing Innovations

Costa Rica has two distinct seasons: the dry season from December to April, which coincides with coffee harvest, and the rainy season from May to November. In recent years, micro-mills have proliferated, requiring only 5% of the water consumption of traditional washed processing plants and eliminating the need for large water tanks and drying patios, thus requiring relatively smaller investments.

Honey processed coffee, characterized by low acidity, increased complexity, and rich sweetness, has become a competitive target in the coffee industry in recent years. Outstanding examples have excelled in major competitions, significantly enhancing the international reputation of various estates.

Sumava Estate

Sumava Estate is a relatively young estate. Originally engaged in coffee trading, Francisco Mena acquired this land and preserved most of the original forest, developing only a small portion for coffee cultivation to maintain the estate's natural ecological balance.

Sumava Estate is situated at altitudes between 1,670-1,790 meters in another renowned Costa Rican region—the West Valley. The significant temperature variations, combined with fertile soil, create ideal conditions for coffee cultivation.

Estate owner Francisco Mena introduced Villa Sarchi, a quality variety that reached the top 13 in the Cup of Excellence. This is a rare variety developed through hybridization of Red Bourbon trees. It resists strong winds, thrives in high-altitude environments, and possesses excellent acidity with various fruit aromas. High sweetness, bright and delicate citrus acidity, deeper raisin and nut aromas, high complexity, and excellent balance characterize this variety.

Most of the estate is left as forest to maintain the natural environment. In estate management, considerable care is taken with broken wood, rotten wood, and weeds—instead of traditional burning, wood is shredded and mixed with organic fertilizer for use on the farm.

Honey Processing Method

Honey processing, also known as Honey Process or Miel Process, produces what's called Honey Coffee. Coffee estates in Costa Rica, Panama, Guatemala, and other regions have adopted this processing method. The so-called honey processing refers to the process of making raw beans by sun-drying with the mucilage intact. After removing the outer pulp from coffee beans, a layer of viscous gelatinous substance remains. Traditional washed processing uses clean water to wash this away, but due to water resource limitations in some high-altitude areas, this direct drying method was developed.

Alongside the two traditional processing methods of washed and natural, honey processing stands out as unique. The taste difference between honey and washed processing: honey processed coffee is sweeter, has higher sugar content, and relatively more body (compared at the same roast level).

Honey processing allows coffee to retain the cleanliness of washed processing. Although the brightness decreases, it increases sweetness and caramel flavors. According to the degree of honey processing, honey processed coffees are divided into yellow honey, red honey, and black honey.

According to summaries from green bean company Nordic Approach run by expert Tim, Seattle Coffee from the US, and Origin Coffee:

Yellow Honey: About 40% of mucilage is removed; drying requires the most direct heat absorption, receiving maximum sunlight exposure, taking about 8 days to reach stable moisture content.

Red Honey: About 25% of mucilage is removed; compared to yellow honey, drying time is longer, reducing direct sunlight exposure time, even using shade nets, taking about 12 days.

Black Honey: Retains nearly 80% of mucilage; takes the longest drying time, minimum of 2 weeks, using coverings to avoid excessive sunlight, preventing too-rapid drying and allowing more complete sugar conversion.

The advantage of honey processing is its ability to best preserve the original sweet flavors of ripe coffee cherries, presenting coffee with elegant brown sugar flavors and stone fruit sweetness, while berry flavors support a red wine aroma base, considered very elegant products.

The biggest difference between honey processing and Brazilian semi-washed processing is that the former uses no water at all, requiring selection of flawless red cherries for sweet mucilage. Honey processing requires higher precision mucilage removal equipment, which must accurately control the thickness of mucilage removal, much like a grinder.

Basically, red honey processing is much more difficult than yellow honey processing, but the flavor profile has more depth. It initially presents slightly wild notes that instantly transform into rich fruit sweetness, reminiscent of the refined fermentation flavors of famous natural Ethiopian Yirgacheffe coffees like Biloya and Aricha, which is stunning.

The main difference between white honey and yellow honey processing is the "drying thickness distinction." Drying thickness determines drying speed and uniformity, which in turn affects the coffee's sweetness and fermentation degree.

Regarding the topic of "Central and South American honey processed coffee lacking clear flavor profiles and excessively pursuing fermentation characteristics," cupping found that white and yellow honey coffees lack the traditional fermentation and soy sauce flavors of honey processing. Instead, with full sweetness, the acidity more closely resembles excellent washed coffee. This honey processing approach brings red berry-like acidity and a clean, refreshing body.

Tarrazu Region and Processing Excellence

Coffee beans produced in Costa Rica's high-altitude regions are world-renowned—rich, mild in flavor but extremely acidic. The coffee beans here are carefully processed, which is why they achieve high quality. Tarrazu, located south of the capital San José, is one of the country's valued coffee growing regions.

While coffee cultivation has a long history, in the past 10+ years, the innovative "dry" processing method has become popular, collectively known as "honey processing." Honey processing is a method between natural and washed processing. It allows coffee to retain the cleanliness of washed processing while significantly increasing sweetness and caramel flavor because it's dried together with the pulp mucilage.

What does failed honey processed coffee taste like?

Failed honey processed coffee has a strong defective natural flavor, similar to rough naturals with onion, durian, fermented tofu notes, and in more severe cases, alcoholic medicinal flavors. Normal honey processed coffee has soft acidity. If it's so acidic that it makes you pucker, it's not a good product.

Honey processing prioritizes freshness. If the production period exceeds 10 months, the charming fruit sweetness will diminish.

Why doesn't natural processing, which retains 100% pulp, have as much sweetness?

Natural processing still retains the fruit skin, and some microbial fermentation processes aren't as deep, so sugar might remain in the dried pulp. Of course, each processing method has its own characteristics, and each year's climate also affects coffee flavor. If you want to understand the flavor differences between different processing methods more deeply, direct tasting is the most intuitive approach.

Flavor Differences Between Yellow, Red, and Black Honey

Simple understanding: processing methods that retain more mucilage result in coffee with richer flavors and higher sweetness. Here are flavor comparisons of several honey processed coffees from our coffee shop:

Phoenix Estate Red Honey: Dried fruit, vanilla, honey, thick and delicate mouthfeel, excellent sweetness, gentle fruit acidity, round and full, persistent aftertaste, with plum, red berry, chestnut notes and strong cane sugar sweetness in the finish, apple peel freshness emerges.

Elisa Red Honey Yellow Honey: Famous for excellent natural geographical conditions and superior regional planting management techniques, nearly perfect classic flavors, with lively citrus notes in acidity, blackberry fruit aromas, thick acidity and mouthfeel, melon sweetness, smooth mouthfeel, stone fruit/light floral notes, while the aftertaste has significant coffee flower aroma—a coffee full of Latin rural charm.

La Minita Estate Black Honey: With the gentle fruit acidity, smooth mouthfeel, and sweet quality berry flavors of honey processing, their most obvious difference is increasing sweetness from yellow, red to black, plus richer fruit notes. The biggest characteristic is amazing sweetness, preserved plum, honey, and brown sugar aftertaste.

Simple Summary:

Sweetness: Black Honey > Red Honey > Yellow Honey > White Honey

Cleanliness: White Honey > Yellow Honey > Red Honey > Black Honey

Balance: Red Honey/Yellow Honey > Black Honey/White Honey

FrontStreet Coffee's Honey Processing Brewing Recommendations

Our so-called techniques are not for adjusting flavors, because flavors are determined by coffee bean origin, processing method, and roasting method. Techniques are for adjusting the speed and ratio of water passing through coffee grounds, thereby regulating the amount of flavor extraction. The quality of flavor necessarily depends on the following points:

1. Speed of water passing through coffee grounds (equipment choice)

2. Water temperature

3. Grind size and condition

4. Roast level

5. Bloom time duration

Usually pour-over extraction, single serving, 15g coffee, with grind size and water temperature slightly adjusted according to different roasts:

1. Yellow Honey (medium roast): Fuji "Oni" grinder 3.5, water temperature 90-91°C, water-to-coffee ratio 1:14

2. Red Honey (medium roast): Fuji "Oni" grinder 4, water temperature 89-90°C, water-to-coffee ratio 1:15

3. Black Honey (medium-light roast): Fuji "Oni" grinder 3.5, water temperature 90-91°C, water-to-coffee ratio 1:14
