What Does Honey Processing of Coffee Beans Mean? And What Is Costa Rica's Raisin Honey Processing?

The processing stage of green coffee beans greatly influences the flavor of coffee. Different fermentation methods guide coffee to produce distinctive flavor profiles. Natural, washed, and honey processing are the three classic methods in coffee processing!

Natural processed coffee typically exhibits rich fruit flavors with complex layers and high sweetness; washed processed coffee is remarkably clean with bright, well-rounded acidity; honey processing combines the advantages of both, creating overall balance with cleanliness and high sweetness.

Compared to the first two methods, honey processing is not as widely used. However, what distinguishes honey processing from them is that it's not a single processing method but rather offers several different variations to choose from.

In the honey processing operation, after removing the skin and pulp of the coffee cherry, the mucilage is retained for drying. Since mucilage is rich in sugar content, the more mucilage remaining on the green beans indicates more attached sugar. The amount of sugar determines the sweetness level of the processed beans, which is why people distinguish between yellow honey, red honey, black honey, and white honey processing based on the amount of residual mucilage!

Raisin Honey Processing: A Special Variation

In addition to these classic "colored" honey processing methods, honey processing also has a very special variation—Raisin Honey Processing.

What is raisin honey processing? Speaking of raisin honey processing, it shares an interesting naming misconception with regular honey processing. Many people have likely seen promotional descriptions for honey processing like "sweet as honey" or "honey-like sweetness," leading some to mistakenly believe that honey processing involves adding honey during the process, or that the name was simply chosen due to its extreme sweetness. Actually, that's not the case~~

Honey processing is called so mainly because during the process, the mucilage oxidizes and presents a very viscous texture, which directly reminds people of honey, which has a similarly viscous quality. Thus, the name "Honey Processing" was established. The misconception about raisin honey processing is almost exactly the same~

Key Differences Between Honey Processing and Raisin Honey Processing

Many friends wonder what differences exist between raisin honey processing and regular honey processing. What impact do they have on flavor? Great! Next, FrontStreet Coffee will answer these questions one by one!

Let's first look at the operation pattern of regular honey processing: The first step in honey processing is to float the coffee beans, sorting out the floating unripe and defective beans.

Then, machines are used to remove the skin and pulp of the coffee cherries, preserving the mucilage layer, allowing the green beans to ferment and dry with the mucilage! The drying time is primarily determined by the amount of mucilage retained—more mucilage means longer sun-drying time (with black honey having the most, followed by red, yellow, and white), until the green beans are dried to the target moisture content, which basically completes the process!

Raisin honey processing, however, differs from them right from the start! After harvesting the cherries, coffee farmers first dry the entire cherries with their husks intact for at least three days. After drying, the coffee cherries take on a shriveled appearance similar to "raisins," after which the skin and husk are removed, and then the honey processing steps begin.

The advantage of this method is that it uses almost no water! Additionally, by sun-drying the cherries, it allows for 100% preservation of the mucilage! Complete mucilage provides more sugar to the coffee beans, presenting the highest sweetness. Although black honey processing retains almost all mucilage, the violent mechanical hulling still affects the integrity of the mucilage to some extent.

This processing method requires higher standards and carries higher risks of spoilage. Coffee farmers need to invest more energy in managing the coffee beans during processing to avoid the development of undesirable negative flavors.

Flavor Profile of Raisin Honey Processing

As Brother Qiang said, the rougher the waves, the more precious the fish. The complex operation of raisin honey processing gives coffee a highly distinctive flavor expression. For example, the Bahia from FrontStreet Coffee's bean selection, which comes from the Canet Estate in Costa Rica, under the enhancement of raisin honey processing, emits rich fermentation aromas. Since its fermentation aroma is very close to that of grapes, it easily reminds people of the taste of raisins.

In addition to regular berry and caramel flavors, it also has distinctive notes similar to blueberry and lavender. After swallowing, the mouth is filled with the lingering taste of dark chocolate, leaving a very deep impression!
