Why Do Costa Rican Coffee Beans Undergo Honey Processing_ Is Sugar Added to Honey-Processed Coffee?

Professional Coffee Knowledge Exchange

Have you ever paid attention to the processing method of coffee beans when buying coffee? Or do you simply order an Americano or a latte at the coffee shop?

If that is how you drink coffee, you probably do not yet know how to appreciate it properly. Next time, try ordering a specialty coffee and noticing its origin and processing method. Listen to the barista's explanation and savor the flavors carefully. Before you enter the sophisticated coffee world, you must have heard of washed coffee and natural coffee, the two most common processing methods.

The flavors of these two methods are very different: washed coffee tends to be acidic, while natural coffee tends to be sweet. Let's use scientific research to explain the difference between them.

Coffee Cherry Structure

Coffee beans are the seeds of the coffee cherry. In appearance the cherry looks like an undried red date, and because it is a small red fruit resembling a cherry it is called a "coffee cherry" in the West.

Structurally, a coffee cherry has several layers from outside to inside: skin, pulp, pectin layer and coffee beans. Different processing methods leave different layers on the bean, which naturally affects the flavor.

After farmers harvest the cherries, they first remove the unripe fruit, then use different methods to process the beans.

Natural Processing Method

If the farmers judge that the weather allows natural processing, they spread the selected cherries directly on large courtyards and let them dry in the sun for 2 to 3 weeks. Once the cherries are dry, the outer shells are removed to obtain the beans. These naturally processed beans retain dried pulp and pectin, making the coffee richer in flavor and sweeter in taste.

Washed Processing Method

In the washed method, selected cherries pass through a depulping machine to remove skin and pulp, leaving the beans with their pectin layer. These are placed in clean water tanks and fermented for 12 to 24 hours by symbiotic bacteria on the coffee itself, such as acetic acid bacteria and lactic acid bacteria. These strains digest the pectin layer outside the beans, producing acids that penetrate the beans, making washed coffee more acidic in flavor.

A 2001 study explored fermentation changes in washed coffee beans. The results found that the pH of the beans was about 5.7 before fermentation, and after 20 hours of fermentation it dropped to 3.8. Sugar content decreased significantly while organic acid content rose substantially, indicating that washed beans do contain more acidic substances, making their flavor more acidic.

Advantages and Disadvantages

Natural and washed processing each have their pros and cons. Natural processing is simple: just use sunlight to dry the cherries. But because it depends heavily on several consecutive weeks of strong sunshine, it is limited by weather. If it rains for several days, an entire batch of cherries can be ruined. High-quality natural beans therefore command premium prices at auction. Washed beans also have processing constraints; in countries with water scarcity or poor water quality, the washed method may not be usable.

Honey Processed Coffee Beans

Honey processing is popular in Costa Rica and is considered a semi-washed method. Unlike washed processing, the beans are not fermented in water tanks, so some pectin layer remains on them. After drying it forms a honey-wax color (amber spots), hence the name "honey processing." This method gives coffee more flavor. No sugar is added.

Exploring Different Coffee Flavors

Next time you drink coffee at a coffee shop, try coffees with different flavors. Don't just order Americanos or lattes.
